Abstract:
The Antillean genus Leptocereus represents an in-situ radiation among the Greater and Lesser Antilles of 19 currently recognized species. Extensive fieldwork carried out in the Dominican Republic over recent years has revealed that the species limits of Leptocereus of Hispaniola are more complex than previously thought. There are four currently recognized species that occur on the island, L. demissus, L. paniculatus, L. undulosus and L. weingartianus. We evaluate species limits in this group based on DNA sequence data and phylogenetic analysis, morphological characters and a survey of herbarium specimens from across Hispaniola. Based on our analyses, it is clear that at least five species occur on the island of Hispaniola, with the new species from Sierra de Bahoruco, L. velozianus, described here. We provide an identification key, distribution maps and photographic plates for all species on Hispaniola based on our own fieldwork and the study of herbarium specimens. The description of yet another species of Leptocereus on Hispaniola reiterates the importance of the poorly studied, but yet biodiverse, seasonally dry tropical forest in the Antilles.

Abstract:
Antecedentes y Objetivos: Los estudios fenológicos han mostrado su utilidad para entender la dinámica de los ecosistemas y pueden ser útiles para la conservación de especies vegetales. En cactáceas son escasos los estudios que evalúan la fenología reproductiva y vegetativa, en particular sobre especies de bosques semideciduos. El presente estudio aborda diferentes aspectos de la fenología de Leptocereus scopulophilus, una cactácea amenazada y endémica presente en un bosque semideciduo de Cuba occidental. Este estudio tiene como objetivos principales caracterizar la fenología de L. scopulophilus, comparar su comportamiento interanual con diferentes regímenes de precipitación y evaluar las relaciones entre las fenofases y las variables ambientales. Métodos: Se seleccionaron 50 individuos adultos y se registraron, mensualmente durante tres años, el número de botones, flores, frutos, así como el crecimiento vegetativo y los retrocesos de una rama seleccionada al azar. Se evaluaron mensualmente el porcentaje de iluminación, la temperatura, la humedad relativa y las precipitaciones. Los patrones anuales e interanuales de cada fenofase fueron comparados mediante estadística circular. La relación existente entre variables ambientales y las fenofases se evaluó con una correlación de Spearman. Resultados clave: Los patrones de floración y fructificación resultaron unimodales con máximos desfasados en un mes. La floración coincidió con el final de la época seca y la fructificación ocurrió al inicio de la época lluviosa. El crecimiento vegetativo fue generalmente de forma aleatoria y simultáneo a la reproducción, mientras el retroceso de las ramas sucedió durante la época lluviosa. La variable más correlacionada con las fenofases fue la iluminación. Conclusiones: La apertura del dosel del bosque semideciduo donde habita L. scopulophilus favorece la reproducción y el crecimiento de sus ramas. Este evento estuvo modulado por la duración e intensidad de las lluvias de la temporada previa.

Full text
Abstract:
Studies of seed mucilage in a number of species suggest that it has multiple ecological roles dependent on species and their environmental context. We evaluate whether mucilage facilitates seed germination for Leptocereus scopulophilus Areces, as well as whether light conditions influence the effect of the mucilage. Three combined treatments of light conditions: (1) shade (10% of sunlight), (2) semi-shade (30% of sunlight), and (3) full light exposure (100% of sunlight), and two seed types (with mucilage and washed) were used. Germinability was affected by light conditions but no effect of mucilage was found; higher germination occurred in shade than in semi-shade conditions. There was no germination in full light conditions. Germination rate (T50) was not affected by light conditions or by the mucilage, or the interaction of both factors. Minimal time to germination (Tmin) was affected by mucilage; seeds with mucilage germinated 2 days later than washed seeds. Thus, facilitation for imbibition of water does not occur in L. scopulophilus seeds. Perhaps the presence of mucilage in seeds of this species serves other purposes such as seed adhesion to soil or to deter predators.

Abstract:
Five new species of caddisflies are described from the Upper Tenasserim Range, including Chimarra keawpradubi n. sp., Ecnomus niyomwasi n. sp., Psychomyia pinsuwanae n. sp., Leptocerus suwannarati n. sp., and Setodes lertpongsombatae n. sp., based on distinctive characters of male genitalia. Chimarra keawpradubi n. sp. differs from other Chimarra spp. in ventral aspect of inferior appendages, each of which is rectangular with a bulging process apicoventrally and with an acute apex. The basal part of each inferior appendage is square and the apical part is narrow in E. niyomwasi n. sp., differentiating it from other species in the genus. Psychomyia pinsuwanae n. sp. differs from P. amphiaraos Malicky and Chantaramongkol 1997, a closely similar species, by characters of the inferior appendages; the inner branch of each inferior appendage has a long, straight spine on its inner side. Leptocerus suwannarati n. sp. can be distinguished from other Leptocerus spp. by the processes of segment X, which are long, thin, and symmetrical. Setodes lertpongsombatae differs from other Setodes spp. in characters of segment X, which is deeply divided subapically into two very long saber-like blades in lateral view.

Males of four new species of caddisflies from Kampong Speu and Siem Reap provinces, Cambodia [Psychomyia kimcheangi n. sp. (Psychomyiidae), Macrostemum siemreapensis n. sp. (Hydropsychidae), Leptocerus angkorwatensis n. sp. (Leptoceridae), and Trichosetodes kampongspeuensis n. sp. (Leptoceridae)] are described and illustrated. Psychomyia kimcheangi n. sp. can be distinguished from other species by characters of the inferior appendages. The main body of each inferior appendage has two branches that are separated near its base but are parallel and close together until the end. In Macrostemum siemreapensis n. sp. the dorsal tip of the phallus has no curved hooklet but instead a knot-like protruding structure in ventral view and looped-like structure in dorsal view. Leptocerus angkorwatensis n. sp. can be distinguished from others by the characters of long needled-like preanal appendages. Trichosetodes kampongspeuensis is distinguished from others by the characters of segment IX in ventral view, which is asymmetrical, and inferior appendages that are not divided and asymmetrical.

The ammonite Leptoceras studeri (Ooster) suggests Late Berriasian to Early Valanginian age. Geomagnetic polarity indicates M16-M14r magnetozones. Therefore, the base of the Valanginian sequence in eastern Crimea should be placed within the M14r magnetozone.

Abstract:
We examined amphipods collected from aboard the deepwater manned submersibles “Mir-1” and “Mir-2” at oil and methane seeps near Cape Gorevoy Utes (Central Baikal). Most of the 23 taxa registered inhabit the entire Lake Baikal within a wide depth range. Two species of the genus Echiuropus are probably new. Leptostenus leptocerus (Dybowsky, 1874), that, until now, was regarded as a rare species, is likely to be an indicator for methane and oil discharge areas. Additional data on the morphology of this species were obtained; cuticular sensory (lateral line organs) and nonsensory microstructures were examined by scanning electron microscopy. The density of nectobenthic amphipods was 5-6 times higher on bitumen mounds than that at neighbouring sites with flat bottom. Maximum density of benthic amphipods was recorded on bacterial mats. No amphipods were observed at the bottom with large oil patches. High density of amphipods at the oil-methane seep is attributed to highly structured habitats and food abundance.

Abstract:
Trichoptera emergences were cumulatively collected from two rivers in central Palawan over 11 months by use of specially modified emergence traps. The quantitative samples were identified at species level. Fifty morphospecies, of which fifteen have been recently newly described, are recognized. The highest species diversity was found in pristine headwater streams. Leptoceridae were most speciose with eleven Oecetis spp., four Leptocerus spp., two Adicella spp., and one species each of Tagalopsyche, Triaenodes, and Triplectides. Highest abundances were observed for Ecnomus cabayugani (Ecnomidae), Dipseudopsis digitata, and Hyalopsyche winkleri (Dipseudopsidae) which contributed alone 34% of the annual emergence. A mid-stream site where mayflies were mainly absent had the highest Trichoptera emergence, brackish water sites the lowest. Many species in Palawan (44% of the taxa) were recorded at a single locality, suggesting that they are stenoecious and that the real number of species on the island might be distinctly higher. This is the first study ever covering quantitative and species-level Trichoptera emergence data for a longitudinal river course.

Abstract:
Macro invertebrate communities from September 2003 to August 2004were studied in riffles and pools of the Mardi and the Vijayapur streams, Pokhara, Nepal. A total of 47 genera (32 from the riffles and 34 from the pools) belonging to 38 families and 12 orders were recorded. The generic richness was lower (30 genera) in the Vijaypur stream than in the Mardi stream (38 genera). Ephemeropteran, dipterans, and trichopteran were found predominant orders comprising 11, 8 and 8 genera respectively. Heptagenids, baetids and leptophlebids; chironomids, ceratopagonids and tip lids and hydropsychids, psychomyids and polycentropodids were dominant sub-groups/families among ephemeropterans, dipterans and trichopterans respectively. The dominant genera were, Heptagenia, Rhithrogena and Baetis; Tendipes, Culicoids and Simulium;Hydropsyche and Psychomyia; Psephenus and Heterlimnius; Octogomphus and Argia and Planaria among ephemeropterans, dipterans, trichopterans, plecopterans, coleopherans, odonates and tricladids respectively. The tax occurred at both streams and sub-habitats were, Ephemera, Heptagenia, Rhithrogena, Ecdyonurus, Ephemerella, Baetis, Leptophlebia, Caenis; Tendipes, Culicoides, Simulium; Hydropsyche, Psychomyia, Psephenus, Heterlimnius and Planaria. Those occurred only in the Mardi stream (Site 1) were Habrophlebia, Siphlonurus; Glossosoma, Hydroptila, Leptocerus; Nemoura, Protonemura, Octogomphus, Argia and Gyraulus convexiculus, whereas, only in the Vijaypurstream (Site 2) were Centroptylum; Antocha, Psychoda, Tabanus, Agapetus and Ectopria. The lower taxa richness at the site having urban influence reflects perturbation of riverine environment due to urbanization and needs measures to control further deterioration.

Abstract:
Abstract Conservation planning of threatened taxa relies upon accurate data on systematics, ecological traits and suitable habitats. The genus Gazella includes taxa with distinct morphologies and ecological traits, but close phylogenetic relationships. The North African Gazella cuvieri and Gazella leptoceros loderi share morphological and physiological characters but the former is darker and found in mountain areas, while the latter is lighter and associated with sand dunes. Here we aim to assess the genetic distinctiveness of these taxa, to characterize their ecological niches and to identify potential occurrence areas, by analysing 327 samples across North-West Africa. Phylogenetic analyses based on mitochondrial (CYTB) and five nuclear gene fragments (KCAS, LAC, SPTBN1, PRKCI and THYR) show that both taxa comprise a single monophyletic group. However, ecological niche-based modelling suggests that populations of these taxa occupy distinct geographic areas and specific environments. Predicted areas of sympatry were restricted, as a consequence of local sharp transitions in climatic traits. The lack of genetic differentiation between these taxa suggests they should be lumped into G. cuvieri, while ecological and morphological differences indicate they correspond to distinct ecotypes. Conservation planning of G. cuvieri should consider the preservation of both mountain and lowland ecotypes to maintain the overall adaptive potential of the species. This integrative approach provides valuable insights in identifying evolutionary units and should be extended to other gazelles.

Abstract:
Temporal and spatial occurrence and upstream flight of lotic mayflies and caddisflies were studied by means of kick netting, slit traps and floating emergence traps in Lake Konnevesi and its outlet stream (Siikakoski), mainly in 1983. Twenty species of mayflies and 78 species of caddisflies were recorded. Clearly lotic mayflies in the material were Baetis subalpinus, Heptagenia sulphurea and Ephemerella mucronata, which occurred only in the stream samples. Females of lotic Baetis rhodani had a long distance upstream flight in the area and occurred frequently in the floating emergence traps especially in sandy littoral habitats of L. Konnevesi. Procloeon bifidum and Nixe joernensis, which in some regions occur mainly in streams, were frequently found in the stony littoral belt of L. Konnevesi. Most of the mayflies recorded in the area were univoltine, but Baetis rhodani and Centroptilum luteolum at least had two generations in 1983. Strictly lotic species among caddisflies were Ceratopsyche nevae, Hydropsyche saxonica, Halesus digitatus, Ceraclea perplexa, Ylodes detruncatus, Athripsodes commutatus and Hydroptila forcipata. These were mainly found in stream samples. A short distance upstream flight of females (c. 0.1-0.4 km) was observed in the populations of H. siltalai, Psychomyia pusilla and Oxyethira frici and a moderate distance flight (at least 0.6 km) by females of Hydropsyche pellucidula, Cheumatopsyche lepida and Polycentropus irroratus. The most abundant caddisflies of the stream Siikakoski (Brachycentrus subnubilus, Neureclipsis bimaculata, Rhyacophila nubila, Agapetus ochripes, Micrasema setiferum and Hydroptila cornuta) were frequently found also in floating emergence traps in the lake (3. 7 km from the rapids). Females of Brachycentrus, Neureclipsis and Rhyacophila favoured traps on sandy substrata while females of Hydroptila were usually found in the stony belt. In the trap material of Agapetus ochripes, males were more abundant than females. According to emergence data, all caddisflies recorded in the area were univoltine though the emerging period of several species such as Rhyacophila nubila and Neureclipsis bimaculata was long. Maximum emergence was observed in early June when brachycentrids were swarming and another peak in August when limnephilids and leptocerids were abundant.

Abstract:
Nomenclatural confusion has been generated regarding the large Australasian terrestrial orchid genus Caladenia following publication from 2001 onwards of three major treatments of Caladeniinae. Here, we review concepts for Caladenia and allied genera in the subtribe, we revise three sister genera of Caladenia (Cyanicula, Ericksonella and Pheladenia), and we present an annotated nomenclatural checklist with many new synonymies and some new combinations. A revised circumscription of ten genera in the Caladeniinae is presented, including both Adenochilus and Eriochilus, which have recently been segregated as monogeneric subtribes by others. We argue for retaining Caladenia in the broad sense, largely reflecting Robert Brown's original concept, differing only in the recognition as genera of Cyanicula, Pheladenia, and Leptoceras, as well as two monotypic genera not known to Brown but later described as species of Caladenia (Praecoxanthus and Ericksonella). Thus Caladenia remains a large Australasian genus of terrestrial orchids with 243 species and six subgenera. This approach maximises nomenclatural stability while ensuring that hypothesised monophyly is upheld in the light of molecular phylogenetics analyses. The valid type for Caladenia is C. carnea, while that for Caladenia sect. Calonema is C. longicauda. The genus Jonesiopsis and generic combination Phlebochilus (Benth.) Szlach. were validly published. These conclusions call into question many recently erected taxa and combinations of other authors. Synonyms of Caladenia include Arachnorchis, Calonemorchis, Drakonorchis, Jonesiopsis, Petalochilus, Phlebochilus and Stegostyla. Pentisia is a synonym of Cyanicula. Calonema (Lindl.) Szlach. and Calonema (Lindl.) D.L. Jones and M.A. Clem. are invalid generic combinations as the name Calonema had already been used for a fungal genus. New taxa described herein include Ericksonella, Cyanicula subgenus Trilobatae, C. aperta, C. ixioides subsp. candida, × Cyanthera and × C. glossodioides. New combinations include Caladenia subgenus Stegostyla (D.L. Jones and M.A. Clem.) Hopper and A.P. Br., C. graniticola (Hopper and A.P. Br.) Hopper and A.P. Br., C. saccata (R.S. Rogers) Hopper & A.P. Br., C. orientalis (G.W. Carr) Hopper & A.P. Br., and C. villosissima (G.W. Carr) Hopper & A.P. Br., and Ericksonella saccharata (Reichb.f.) Hopper and A.P.Br.

Abstract:
The sawfly genus Euura of the tenthredinid subfamily Nematinae, in which species level taxonomy has long been regarded as controversial, is particularly species rich in northern parts of the Holarctic. Among a majority of species with more or less free-living larvae, a sizeable minority belongs to a monophyletic lineage whose larvae complete their whole development in galls. We present illustrated keys to the adults and galls of 66 gall-inducing Euura species that occur, or might occur, in northern Europe. The distribution of these species is briefly reviewed, with an emphasis on the fauna of Sweden, where 55 species are now definitely recorded, two of them for the first time (E. bigallae, E. myrtilloidica). The species-level taxonomy of gall-inducing Euura remains partly problematic. Nominal species described on the basis of experimentally tested or assumed host plant specificity, but which cannot be recognised using morphological or genetic characters, are treated as conspecific with currently indistinguishable segregates ("host-plant races") associated with other Salix species. 20 new synonymies are proposed (valid names in parentheses): Eupontania acutifoliae baltica Vikberg & Zinovjev, 2006 and Pontania acutifoliae daphnoides Zinovjev, 1993 (Euura acutifoliae (Zinovjev, 1985)), Euura boreoalpina Kopelke, 2001 (Euura lanatae Malaise, 1921), Euura cinereae Kopelke, 1996 preoccupied and Euura lapponica Kopelke, 1996 preoccupied (Euura auritae Kopelke 2000), Euura gemmacinereae Kopelke, 2001 and E. nigritarsis Cameron, 1885 (Euura mucronata (Hartig, 1837)), Euura phylicifoliae Kopelke, 2001 (Euura myrsinifoliae Kopelke, 2001), Nematus westermanni Boheman, 1852 nomen oblitum (Euura scotaspis (Förster, 1854) nomen protectum), Nematus acerosus Hartig, 1840 (Euura saliciscinereae (Retzius, 1783)), Nematus alienatus Förster, 1854 and Phyllocolpa rolleri Liston, 2005 (Euura leucapsis (Tischbein, 1846)), Nematus angustus Hartig, 1837 (Euura atra (Jurine, 1807)), Nematus erythropygus Förster, 1854 (Euura leucosticta (Hartig, 1837)), Nematus impunctatus Herrich-Schäffer, 1840 (Euura amerinae (Linnaeus, 1758)), Pontania carinifrons Benson, 1940 and Phyllocolpa plicaglauca Kopelke, 2007 (Euura destricta (MacGillivray, 1923)), Pontania obscura Kopelke, 2005 (Euura bridgmanii (Cameron, 1883)), Pontania viminalis var. lugubris Enslin, 1918 and Eupontania collactanea rosmarinifoliae Vikberg & Zinovjev, 2006 (Euura collactanea (Förster, 1854)). Euura weiffenbachiella nom. nov. is proposed as a replacement name for Euura weiffenbachii Ermolenko, 1988; preoccupied in Euura by Pteronidea weiffenbachi Lindqvist, 1958 (Euura piliserra (Thomson, 1863)). Lectotypes are designated for the following 9 taxa: Euura insularis Kincaid, 1900, Euura lanatae Malaise, 1921, Euura lappo Malaise, 1921, Euura lappo var. hastatae Malaise, 1921, Nematus acerosus Hartig, 1840, Nematus leptocerus Förster, 1854, Nematus vallisnierii Hartig, 1837, Pontania megacephala Rohwer, 1908, and Pontania piliserra var. mascula Enslin, 1915. Because of secondary homonymy within Euura, the valid name of the Nearctic species E. arctica MacGillivray, 1919 is E. delicatula (MacGillivray, 1919). The Nearctic Euura megacephala is removed from synonymy with the Holarctic E. destricta and treated as a valid species. 34 species names are newly combined with Euura.

Abstract:
Due to the scarce information about the root organization of Galeandra genus representatives, this study aimed to describe the root anatomy of Galeandra leptoceras, describing adaptations related to hydric relations and characters of taxonomic interest. Five roots of three plants were fixed and preserved in 50% alcohol. These ones were cut in midline with the use of razors. The sections were stained with 0.05% Safrablau and mounted in glycerin. It was observed that the roots of species are structurally adapted to epiphytism; however, some anatomical features show that this species requires more frequent watering or environments with constant humidity. The anatomical characteristics described for roots support results reported by authors that include the genus in subtribe Catasetinae, Cymbidieae tribe. The anatomical characters have generic uniformity, serving as a tool for the genus’s systematic.

Abstract:
The effect of anthropogenic activities on natural intermittent stream and diversity of adult caddisfly were studied at the University of Phayao, Thailand. The caddisfly adults were collected monthly from 2 intermittent streams (the Huai Thub Chang and Huai Luang streams) from February to May 2015 (cool-dry to hot-dry season) using a black-light trap. Huai Thub Chang stream received wastewater from the oxidation pond, while Huai Luang stream was affected by an agricultural field of the university. Both streams are located in a deciduous forest. The 14 species of 7 families were collected and identified. Cheumatopsyche lucida (Hydropsychidae) and Leptocerus dirghachuka (Leptoceridae) were found in both streams. C. lucida was the most abundant species. Micrasema turbo, Amphipsyche meridiana, C. globosa, Diplectrona lavinia, Macrostemum dohrni, Marilia sumatrana, and Wormaldia relicta were found only in Huai Thub Chang stream, whereas C. dhanikari, Lepidostoma doligung and Chimarra toga were found only in Huai Luang stream. A high number of C. lucida in both streams from February to April reflected a drought effect on the emergence of the caddisflies. Huai Thub Chang stream had a higher diversity of Trichoptera species than Huai Luang stream because of the variety of substrate types which were suited for the larval stage, especially hydropsychids.

Abstract:
The life cycle of Digenea subclass trematodes that mostly involves snails as intermediate host in the larval stage in the form of sporocysts, redia and cercariae. This study aims to determine the species of freshwater snails, populations and stages of trematoda larvae that infect freshwater snails in the paddy fields and also the factors that influence the population of trematoda larvae. This research method uses purposive random sampling. Snails were collected from paddy fields in Sleman Regency, Yogyakarta City and Bantul Regency, Special Region of Yogyakarta. Snails and Trematodes larvae were identified based on morphological characters with a microscope. The results showed that the species of freshwater snail as an inang antara of Trematode was Lymnaea sp. (96.9%), Pomacea canaliculata (2.6%), and Brotia sp. (0.5%). The total population of trematoda larvae in freshwater snails was 4329 individuals with the largest population in Sleman Regency (2784 individuals). Trematode larval stages found were sporocysts (4.8%), redia (8.3%), Leptocercous type cercariae (35.2%), and Furcocercous type cercariae (51.7%). The most trematode larvae found in fresh water snail was Furcocercous type cercariae. Factor affecting trematode larvae population are the species and abundance of freshwater snail.
