Abstract:

This research aims to analyze the needs of tourists for this type of wellness tourism. The research was carried out with a survey method on 118 tourists who visited Ba Vi National Park. Research results show that 89% of tourists surveyed have a desire to travel healthily to improve their physical and mental health. Ba Vi National Park has many favorable conditions for the development of wellness tourism. Tourism products that meet the needs of tourists mainly focus on products that are close to nature and have health care activities. Factors of income, location of destination, and attractiveness of natural landscape are the main factors affecting the demand of tourists.

Abstract:

Ba Vi National Park, one of 28 Vietnamese National Parks, is currently preserved and exploited for a variety of purposes, including the preservation of intact natural forest ecosystems and genetic resources of rare plants and animals. This paper presents the monitoring results of microbial contamination in surface water environment of the Ba Vi National Park (Ha Noi) in the period 2013-2014 and 2018. The results showed that total coliform (TC) density varied from 23 to 11,000 MPN/100ml in bimonthly observation in 2013-2014 which was lower than that one of sampling campaign in 2018, from 900 MPN/100ml to 8,100 MPN/ml. Fecal coliform (FC) densities varied from 0 to 110 MPN/100ml in 2013-2014, lower than in 2018, when it varied from 0 MPN/100ml to 600 MPN/100ml. At several observation times, both TC and FC were higher than the allowable values of the Vietnam national technical regulation QCVN 08-MT: 2015/BTNMT column A1 for surface water quality. The exceeded values of TC and FC than the allowable values and the increase trend from the 2013 to 2018 periods indicated the potential risks to the public health in this region when people use water for domestic and agricultural purposes. Our results provide dataset for environmental management in the Ba Vi National Park in order to protect the eco-environment in parallel with social-economic development. Vườn Quốc gia Ba Vì, một trong 28 vườn quốc gia của Việt Nam hiện đang được bảo tồn và khai thác cho nhiều mục đích, trong đó có bảo tồn nguyên vẹn các hệ sinh thái rừng tự nhiên, các nguồn gen động, thực vật quý hiếm, các đặc sản rừng và các di tích lịch sử, cảnh quan tự nhiên trong vùng. Bài báo trình bày kết quả quan trắc, đánh giá mức độ ô nhiễm vi sinh vật trong môi trường nước mặt tại Vườn Quốc Gia Ba Vì, Hà Nội giai đoạn 2013-2014 và 2018. Kết quả cho thấy mật độ coliform tổng số (TC) biến đổi trong khoảng từ 23 – 11.000 MPN/100ml trong các đợt quan trắc định kỳ 2 tháng/lần trong hai năm 2013 - 2014 và trong khoảng từ 900 – 8.100 MPN/100ml trong một đợt quan trắc năm 2018. Mật độ fecal coliform (FC) biến đổi trong khoảng từ 0 - 110 MPN/100ml năm 2013 -2014 và từ 0 - 600 MPN/100ml vào năm 2018. Vào một số thời điểm quan trắc, mật độ FC và TC vượt giá trị cho phép của quy chuẩn kỹ thuật Quốc Gia QCVN 08-MT:2015/BTNMT cột A1 về chất lượng nước mặt. Các giá trị TC và FC vượt quá giá trị cho phép và xu hướng gia tăng TC và FC từ 2013 -2018 cho thấy nguy cơ tiềm tàng khi người dân sử dụng nguồn nước này cho các mục đích sinh hoạt và nông nghiệp. Như vậy, kết quả của nghiên cứu này nhấn mạnh nhu cầu giám sát thường xuyên chất lượng nước và cần thực hiện các giải pháp hiệu quả để xử lý và quản lý nguồn gây ô nhiễm trong khu vực nhằm bảo vệ môi trường sinh thái song song với phát triển kinh tế - xã hội của khu vực.

Abstract:

The Vietnam Skink (Plestiodon tamdaoensis) was described from Tam Dao National Park, Vietnam, in 1937, and the species is currently known only from northern Vietnam and Hong Kong of China, whereas the Devouring Forest Skink (Scincella devorator) was described from Yen Tu Nature Reserve, Vietnam, in 2004, and the species is endemic to northern Vietnam. As a result of our field surveys in 2023 and 2024 in Ba Vi National Park, Vietnam, we reported new distribution records, morphological data, and natural history of Plestiodon tamdaoensis and Scincella devorator. In addition, we used species distribution modeling to predict the potential distribution of these species. The model showed that the potential distribution of P. tamdaoensis is approximately 110,000 km2 and that of S. devorator is approximately 130,000 km2, covering northern Vietnam, southern China, and northern Laos, significantly expanding its known range compared to the IUCN range map.

Abstract:

Among the protected area system of Vietnam, Cat Ba appears as an ideal national park for biodiversity research and conservation. It covers a large area of karst landscape including islands and different ecosystems ranging from forests, wetland, mangroves, caves and others. Since the establishment of Cat Ba National Park in 1986, biodiversity research and conservation within the park have been strongly promoted and raised. The park has been well known as home to highly diverse flora and fauna with many species endemic to the archipelago and Vietnam. A series of projects and programmes have been effectively implemented for urgent and long-term conservation of threatened species. However, results from scientific research also indicated that many sites and species are still almost unstudied while several sections of the park’s buffer zone are affected by human activities including unscientific development of ecotourism. We recently conduct a field survey and recorded 2 bat species and echolocation calls in their natural habitats. This paper provides an overview of achievements with recent records and recommendations for strengthening conservation of biodiversity and habitats in the park and surroundings. Trong hệ thống khu vực bảo vệ của Việt Nam, Cát Bà là một vườn quốc gia có điều kiện thuận lợi đối với công tác nghiên cứu và bảo tồn đa dạng sinh học. Vườn quốc gia này bao gồm diện tích lớn cảnh quan núi đá vôi với các đảo và hệ sinh thái đặc trưng như rừng trên núi, đất ngập nước, rừng ngập mặn, hang động và nhiều hệ sinh thái khác. Từ khi thành lập Vườn Quốc gia Cát Bà năm 1986, công tác nghiên cứu và bảo tồn đa dạng sinh học được quan tâm và thực hiện ngày càng nhiều. Vườn quốc gia cũng chứa đựng khu hệ động vật và thực vật đa dạng với nhiều loài đặc hữu cho quần đảo và Việt Nam. Nhiều dự án và chương trình đã được thực hiện nhằm bảo tồn cấp bách và lâu dài những loài bị đe dọa. Tuy nhiên, những kết quả nghiên cứu khoa học cũng cho thấy nhiều khu vực trong phạm vi vườn quốc gia gần như chưa được nghiên cứu trong khi một số tiểu khu thuộc vùng đệm đang bị ảnh hưởng bởi hoạt động của con người như sự phát triển du lịch. Chúng tôi đã ghi nhận được 2 loài dơi cùng với tiếng kêu siêu âm trong môi trường sống tự nhiên của chúng qua thời gian điều tra thực địa vừa qua. Bài báo này cung cấp dẫn liệu tổng quan và cập nhật về những kết quả đã đạt được với những thông tin cập nhật và đề xuất nhằm thúc đẩy công tác bảo tồn đa dạng sinh học và sinh cảnh ở vườn quốc gia và vùng phụ cận trong tương lai.

Abstract:

Three new species of Indochinamon Yeo & Ng, 2007, are described from Vietnam. The poorly known Vietnamese species Indochinamon kimboiense (Dang, 1975) is redescribed. The holotype of I. kimboiense is lost, and a topotypic specimen is designated as the neotype. Indochinamon bavi n. sp. from Ba Vi National Park, Ha Tay Province, and I. phongnha n. sp. from Phong Nha, Quang Binh Province, are allied to I. kimboiense, but can be distinguished by the characters of the carapace, chela and male first pleopod. Indochinamon dangi n. sp. is allied to I. lipkei (Ng & Naiyanetr, 1993) [type locality northern Thailand], but can be distinguished by characters of the carapace, telson, and male first pleopod.

Abstract:

A new species, Quercus xuanlienensis Binh, Ngoc & Bon, is described from Xuan Lien Nature Reserve, Vietnam. The new species is morphologically similar to Q. edithiae Skan, in having 8–11 pairs of secondary veins, bowl-shaped cupules and ellipsoid to cylindrical-ellipsoid and basally convex nuts. It differs in having serrulate leaf margins only at apical 1/5–1/7, almost entire margins of bracts on cupule and much longer nuts. The species is also similar to Q. fleuryi Hickel & A. Camus in having leaves glabrous on both surfaces with only an apically serrulate margin but differs in having shorter petioles, cupules enclosing 1/5 of the nut and much longer nuts. In addition, Q. disciformis Chun & Tsiang. and Q. bella Chun & Tsiang., previously known from China, are newly recorded from Ba Vi National Park, Vietnam.

Abstract:

Assessing tourist satisfaction has become a hot topic for tourism research in recent years. Many studies have shown that improving tourist satisfaction not only has a positive impact on service providers and destination reputation, but also increases tourist loyalty, lowers price elasticity, lowers future transaction costs, and increases production efficiency (Chen et al., 2012; Nguyen Trong Nhan et al., 2014). Some other studies have also shown that improving tourist satisfaction will stimulate word-of-mouth advertising (Ekinci, 2004; Gonzalez et al., 2007; cited by Chen et al., 2012). Therefore, assessing tourist satisfaction is very important, it helps to find out the existing problems, limitations or strengths of service quality from the perspective of tourists, thereby finding solutions to contribute to improving the ability to provide better and better services. Hanoi as the capital, the economic - political - social center of Vietnam. Therefore, the tourism - hotel industry not only attracts tourists but also diplomatic, business and economic - political - social event participants. Hanoi has great potential for tourism - hotel with hundreds of famous landscapes, historical and cultural relics, traditional craft villages, festivals. In terms of natural tourism resources, Hanoi is famous for Huong Tich as "Nam Thien De Nhat Dong". A series of lakes such as West Lake, Hoan Kiem Lake, Dong Mo, Suoi Hai, Quan Son, not to mention the potential of mineral water resources. Hanoi also has many scenic spots around the foot of Ba Vi mountain, creating branded eco-tourism resorts such as Ao Vua, Vua Ba, Khoang Xanh, Suoi Tien, Thac Da, Thac Nga, Ba Vi National Park, etc. Keywords: Satisfaction, Tourists, Service Quality.

Abstract:

We describe Vietnamophryne cuongi sp. nov., a new species of microhylid frog from northern Vietnam, based on morphological and molecular differences. Although superficially similar to remaining Vietnamophryne members, the new species differs by a number of diagnostic morphological characters, such as body size, habitus, head dimensions, finger and toe morphology, skin texture, as well as colour pattern. Phylogenetic analyses based on a fragment of the mitochondrial 16S gene place the new species to be sister to V. orlovi, from which it differed by 2.4% genetic divergence. We also describe the first female known of V. orlovi, collected in the forest of Phia Oac-Phia Den National Park, Cao Bang Province. The latter species, for which we provide an extended description herein, was recently described based on the single male type specimen only from the same site in northern Vietnam. Vietnamophryne cuongi sp. nov. is only known from three specimens, two adult females and a juvenile, from the evergreen tropical forest of Ba Vi National Park, Hanoi. As such, it is likely to be at high risk of habitat loss. Considering its high ecological specialization and the small known distribution range of the new species, we propose Endangered as IUCN Red List status.

Abstract:

Abstract Four new species of Heth are described from diplopods collected in different parts of Viet Nam: Heth vietnamensis sp. n. and H. tonkinensis sp. n. in Ba Vi National Park, Ha Tay Province; H. taybaci sp. n. in Lai Chau Province and H. taynguyeni sp. n. in Chu Yang Sin National Park, Dak Lak Province. The new species are morphologically related to those described from Papua New Guinea, but are differentiated by the form of the female cuticular armature. Heth vietnamensis sp. n. is characterised by the posterior end of the lappets overhanging the anterior pair of the lateral spines, the similar size of spines in both pairs and the presence of two pairs of small papillae on the anterior lip of the cloacal aperture. Heth tonkinensis sp. n. can be differentiated from the other species by having the longest lappets, lateral spines with fused bases and the unequal-sized spicule heads. Heth taybaci sp. n. has the shortest lappets of the described Vietnamese species, has gaps between the lateral spines that are wider than the spine base and the presence of a bursa-like cuticular fold at cloacal aperture level. Heth taynguyeni sp. n. males also have a bursa-like cuticular fold but, unlike H. taybaci sp. n., this species is characterised by the bifurcate distal tips of the spicule and the undulating inner margin of the lappets.

Abstract:

For a sustainable tourist destination, a multi-criteria assessment is essential. The assessment results are the basis for managers to make optimal development decisions for the destination. In particular, for the nature-based tourist sites (protected areas, national parks), the assessment of tourism potentials will establish the basis for protecting, monitoring ecosystems, and managing the tourism sustainable development calendar. The Multi-Criteria Method and additional methods were applied to assess tourism potentials as well as to propose conservation measures for Cat Ba National Park in Vietnam. Through the assessment of six criteria (location/accessibility, attractiveness, tourist capacity, environmental sustainability, travel duration, and tourism infrastructure/tourism technology), the results indicate that Cat Ba National Park (Vietnam) is an attractive tourist destination with a good tourist capacity, a convenient location for tourists to move, and a long tourism time of the year. However, Cat Ba National Park is a place where environmental sustainability is still limited; its exploitation needs to be considered along with its conservation, degradation prevention, and ecosystem monitoring.

Abstract:

Cat Ba National Park is the core zone of the Cat Ba Archipelago Biosphere Reserve. It contains quite diverse and unique ecosystems including 776 ha of mangrove forest. Although bats of the park were included in many publications, none were recorded from the mangrove ecosystem. We recently conducted field surveys through the wetland areas of the park and recorded three horseshoe bat species: Marshall's horseshoe bat (Rhinolophus marshalli), Pearson’s horseshoe bat (Rhinolophus pearsonii), and the least horseshoe bat (R. pusillus). Of these, R. pearsonii is the most common species. We here provide morpholocal and acoustic features of each species with notes on the importance of the mangrove forest in the park for bat research and conservation.

Abstract:

Dung beetles (Coleoptera: Scarabaeidae) are considered as an indicator group of habitat modifications. However, little is known about the indicative value of dung beetles for changes in tropical island karst ecosystems of Vietnam. We sampled dung beetles along the gradient of forest disturbances from primary forests to old secondary forests (> 15 years since abandonment), young secondary forests (< 10 years since abandonment) and Acacia plantations (< 10 years old) in Cat Ba National Park, Hai Phong Province. Our main aim is to detect dung-beetle species that could be used as potential indicator species of habitat changes. In total, 10 dung-beetle species were identified as potential indicator species of different forest types in Cat Ba National Park based on the indicator value (IndVal) of Dufrêne & Legendre (1997). Four species were identified as true specialists in old secondary forests including Onthophagus phanaeiformis (Boucomont, 1914), Sisyphus neglectus (Gory, 1833), Copris szechouanicus (Balthasar, 1958), and Onthophagus dorsofasciatus (Fairmaire, 1893). Three species, comprising Onthophagus sp1., Synapsis tridens (Sharp, 1881), and Onthophagus trituber (Wiedemann, 1823) could be considered as the indicator species of primary forests. Caccobius unicornis (Fabricius, 1798) and Onthophagus jeannelianus (Paulian, 1945) were indicator species of young secondary forests; Onthophagus luridipennis (Boheman, 1858) was the indicator of Acacia plantations. In the following, we gave an annotated and illustrated checklist of the indicator dung-beetle species that may be broadly useful for habitat monitoring and conservations in Cat Ba National Park.

Abstract:

Bat flies are highly specialized ectoparasites of the superfamily Hippoboscoidea and only associate with bats. They were rarely documented in Vietnam due to limited study in the country. Between 2017 and 2020, we conducted a series of field surveys in six localities in northern and central Vietnam with an emphasis on bat flies. Bats were captured using mist nets, harp traps, and handnets then morphologically identified following literatures relevant to the bats of each study site. Bat flies were collected using fine forceps and preserved in 70% alcohol for morphological identification. Twelve individuals of Brachytarsina cucullata and thirty-five individuals of Raymondia pseudopagodarum of the family Streblidae were collected over the surveys. Of which, B. cucullata is new to two localities in northern Vietnam (Nham Duong Mountain Area and Ha Long Bay) while R. pseudopagodarum is new to five localities in both northern and southern Vietnam (Bach Ma National Park, Cat Ba National Park, Ha Long Bay, Cu Lao Cham Island and Sop Cop Nature Reserve). Within Vietnam, B. cucullata and R. pseudopagodarum were only recorded from Cat Ba National Park and Vu Quang National Park, respectively. Notably, the previous records from Vietnam did not include either description or illustration. We here provide brief descriptions and illustrated photos of each species for morphological identification of these two bat fly species. A map showing the distributional records of each species is also included in this paper.

Abstract:

Climate change and an increase in the greenhouse effect are a matter of global concern. One of reasons for this phenomenon is the increase in greenhouse gases, especially CO2. Therefore, the authors investigated CO2 absorption from forests of 45 plots in Ba Be National Park, characterized by 3 forest states as rich, medium and poor forest, rehabilitated forest after exploitation to estimate carbon sequestration of the forest. In which, the carbon stock of rich forest reaches 273.17 tones/ha, the medium forest is 136.23 tones/ha and the poor forest, rehabilitated forest is 42.06 tones/ha. With a forest growth rate of 1.8% per year, the carbon sequestration in Ba Be National Park for 3 forest states is about 16,499 tones per year. This will contribute to improve environmental quality, reducing greenhouse gas emissions and creating a scientific basis for managers to develop a payment mechanism of forest carbon sequestration services.

Abstract:

Prior to the present study, literature reviews revealed that 31 species of bats belonging to six families and 14 genera were identified in Cat Ba National Park in Northern Vietnam However, the conservation status of many species remains unclear and is still subject to debate. Among the 31 species, 11 are common while the remainder have been rarely captured since 1942. At least two species, Hipposideros alongensis and H. khaokhouayensis, which are globally considered vulnerable, are very common in Cat Ba National Park. This paper provides an update on the current status of each species based on data from recent field surveys with reference to previous publications and the current IUCN Red List (iucnredlist.org). Results from the recent surveys included eight individuals provisionally identified as Myotis cf. pilosus. The taxonomic status of five species (Aselliscus dongbacanus, Hipposideros gentilis, Hipposideros grandis, Miniopterus magnater, Murina harrisoni) are updated following recent assessments. This information will inform future research and conservation actions.

Abstract:

Banke national park, located in Banke district of western Nepal with an area of 550 sq. km was established as the tenth national park in 2010 A.D. Forest community structure, species diversity and natural regeneration were studied in the Park. A total of 1067 plots at every interval of 200m were laid by line transect method for the study. In each plot three concentric rings of radii of 10m, 5m, and 1m were laid down for the study of trees, shrubs/saplings and herbs/seedlings respectively. The park was floristically rich with a total of 113 species of trees representing 57 genera and 28 families. Similarly 85 species of shrubs including climbers and 107 species of herbs including herbaceous climbers, and grasses were recorded. The obtained results from the size class distribution of the trees resembling inverse ‘J’ shape indicated the good regenerating capability of the forest in the park. Fifty eight species of saplings and 40 species of seedlings of trees were recorded. From the quantitative study of the trees, the dominant species was Shorea robusta based on IVI (important value index) values, which was followed by Terminalia alata, Anogeissus latifolius, Mallotus philippinensis, etc. The total density stand (D) and basal area (BA) of the park were 291.48 trees/ha and 21.13 m2/ha respectively. The highest density (D) and the basal area (BA) of S. robusta was 46.07 trees /ha and 5.07m2/ha respectively. The species diversity index (H) of the tree species in BaNP was 1.32, with species evenness (J) of 0.64 and index of dominance (C) of 0.08. A total of seven forest community types were estimated in the Park. The size class distribution diagram of all trees showed right skewed (inverse J shaped) pattern indicating a good regenerating capability of the forest. The regeneration of S. robusta, T. alata and A. latifolius were higher in comparison to other tree species which was indicated by the higher seedlings and saplings density of them. S. robusta was the dominant with saplings density of 200.49 / ha and seedlings density of 27153.4 /ha.Nepal Journal of Science and Technology Vol. 16, No.1 (2015) pp. 17-30

Abstract:

At the present time, non-vascular plants (bryophytes) are less studied, especially in Vietnam. Therefore, this research focuses on studying biological activities of some bryophytes species collected in Bidoup–Nui Ba National Park, such as antioxidative, antibacterial activity, acetylcholinesterase inhibitory activity and quantitative analysis of the major secondary metabolites. Moreover, one of the most potential species was micropropagated in vitro in order to get the initiative pharmaceutical materials. Among the six bryophyte species collected in Bidoup–Nui Ba National Park, three of them are mosses (Pyrrhobryum spiniforme, Bryum argenteum and Campylopus umbellatus) and three of them are liverworts (Lepidozia fauriana, Plagiochila trabeculata and Schistochila blumei). Our results showed that L. fauriana had the highest antioxidative activity and acetylcholinesterase inhibitory activity (IC50 = 6.617 ± 0.080 mg/mL), S. blumei had the potent antibacterial activity. In vitro propagation results showed that silver moss could be micropropagated using spores in MS medium supplemented with 1 mg/L 2,4-D and 2 mg/L kinetin.

Abstract:

Abstract The intensity of wildlife conflicts with humans has recently tended to increase. The conflict between humans and wildlife is a problem that can cause material losses and loss of life. Conflicts can occur because of the lack of food resources in the forest. Another factor is the high rate of land conversion; forest ecosystems are converted into plantation land. This problem is worrying because numerous wild animals descend into human settlement areas to find food and cause conflict with humans. This study was conducted in March 2021 in nine villages around Gunung Leuser National Park (GLNP), Management Section of National Park (MNSP) VI Besitang. The purpose of this study was to calculate how much loss was caused by wildlife-human conflicts in the village around the MNSP VI Besitang, GLNP. This study found that conflicts between humans and wildlife are incredibly detrimental. The method used in this research is an open interview with the community and key respondents with purposive sampling, counting crop damage, livestock eaten, harvest failure, building damage, and fatalities caused by human-wildlife conflict. This study also includes the time lost by the community due to the conflict, which differs from similar studies. The study’s results found a value economic loss in Besitang is Rp. 224,254,550 /year.

Abstract:

Cat Ba National Park contains a high diversity fauna of bats including a species endemic to Vietnam. Since 1999, we conducted a series of bat surveys in the park with an investigation into bat files. All individuals of flies collected from each bat individual were preserved in a plastic tube filled with pure alcohol. They were analysed and identified at the Institute of Ecology and Biological Resources. Results from our research provide records of 8 bat fly species belonging to 4 genera, 2 families; of these, 3 species belong to the family Nycteribiidae (Basila roylii, B. burmensis, B. pundibunda) and 5 remaining ones belong the family Streblidae (Ascodipteron phyllorhinae, A. wenzeli, Brachytarsina amboiensis, B. cucullata, Maabella stomalata). These fly species parasitize 8 bat species belonging to 4 families: 5 species of Hipposideridae (Hipposideros alongensis, H. armiger, H. grandis, H. khoukhouayensis, H. pomona), 1 species of Miniopteridae (Miniopterus fuliginosus), 1 species of Rhinolophidae (Rhinolophus marshalli) and 1 species of Vespertilionidae (Hypsugo pulveratus). Basilia pundibunda was the most common bat fly species within the study area. The first data on ecological correlation between flies and bats from Vietnam were also recorded and given in this paper.

Full text

Abstract:

Coarse woody debris (CWD) has historically been extensively utilized in Korea, with significant accumulation occurring mainly after the establishment of protected areas. This study, conducted in Odaesan National Park (designated in 1975), investigated the distribution and characteristics of CWD across five forest types with permanent plots. It also examined the effects of human and natural disturbances on CWD dynamics and evaluated its role in carbon storage. CWD mass varied significantly, ranging from 0.7 Mg ha−1 in Pinus-Quercus (PQ) forests to 31.9 Mg ha−1 in Broadleaved–Abies (BA) forests. The impacts of disturbances shifted markedly before and after the park’s designation; prior to this, human activities such as logging substantially affected BA, PQ, and Prunus-Salix (PS) forests, while Quercus-Tilia (QT) forests were primarily impacted by wildfires. After designation, natural disturbances became the primary contributors to CWD accumulation, with a major windstorm in BA forests adding 12.09 Mg ha−1 of CWD (37.8% of the total). Late-successional forests exhibited higher CWD mass, advanced decay stages, and greater diversity, as well as elevated CWD-to-carbon storage ratios, highlighting their role as crucial carbon reservoirs. In light of climate change, these findings emphasize the need for forest management practices that enhance CWD’s contributions to biodiversity conservation and carbon storage.

Abstract:

Arisaema condaoense V.D. Nguyen was described as a new species from Con Dao National Park, Ba Ria–Vung Tau Province, Vietnam in 2000. However, this species has been suspected of being a form of Arisaema roxburghii Kunth, a species widespread in the whole Indochina and Malay Peninsula. This was due to the original description based on dried specimens with male inflorescences only. Morphological characteristics of female inflorescences, which are of taxonomical importance to identify the species, have not been known. In June 2015, we re-sampled the plant in Con Dao National Park with both male and female inflorescences for detailed examination of morphological characteristics. Besides, the matK gene of the chloroplast genome of this species was sequenced to analyse its phylogenetic relationship with other Arisaema species. The gathered morphological and molecular data indicate that A. condaoense is certainly a distinct species, not a synonym of A. roxburghii. The noted morphological characteristics also provide key differences to distinguish A. condaoense from two other morphologically close species of sect. Fimbriata (i.e A. maxwellii from Thailand and A. pierreanum from Vietnam which also share yellow spathes and several other characteristics in common), which are supported by the molecular data. Thus, the species is endemic to Con Dao National Park in Ba Ria–Vung Tau Province, Vietnam. Furthermore, this study allows us revising the description of A. condaoense with, for the first time, supplemental key taxonomic characteristics and illustrating colourful photographs taken from the fresh materials. A key to all eight known Vietnamese species of sect. Fimbriata is also given.

Abstract:

The description of a new species of oribatid mites (Oribatida) of the family Zetorchestidae—Zetorchestes krisperi sp. nov.—is proposed based on adult and tritonymph specimens collected from rainforest soil of Bi Dup-Nui Ba National Park (southern Vietnam). We also review the distinguishing characteristics for Zetorchestes species and present an identification key to Zetorchestes species of the world. Diagnostic features of Zetorchestes nymphs are discussed.
