Abstract:

Eunicida have a complex jaw apparatus with a fossil record dating back to the latest Cambrian. Traditionally, Eunicidae, Onuphidae, and Lumbrineridae were considered closely related families having labidognath maxillae, whereas Oenonidae with prionognath type maxillae were thought to be derived. Molecular phylogenies place Oenonidae with Eunicidae/Onuphidae, and Lumbrineridae as the most basal taxon. Re-evaluation of the jaw types based on morphology and ontogeny demonstrated that the labidognaths Eunicidae and Onuphidae have a closer relationship to the prionognath Oenonidae than was previously thought. Lumbrineridae are neither labidognath nor prionognath; therefore a new type, Symmetrognatha, is proposed. Homologies of jaw elements and considerations of functional aspects of the jaw apparatus are explored to present a hypothesis of the Eunicida phylogeny. The earliest fossils are of placognath and ctenognath types, lacking maxillary carriers. While the former are extinct, the latter are represented by the extant Dorvilleidae. The interpretation of relationships between the carrier-bearing families depends on whether the carriers are thought to have evolved once only or twice independently. The similarity of the carrier structure and their associated muscles suggests the former, placing the Lumbrineridae as sister to Eunicidae/Onuphidae and Oenonidae. However, the ontogeny of the eunicid/onuphid apparatus as well as its adult structure differ greatly from those of lumbrinerids, indicating that the lumbrinerid carriers may have evolved independently and earlier than in eunicids/onuphids and oenonids.

Abstract:

In this study, we analyze the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation. Eunicida is an order of Errantia annelids characterized by the presence of ventral mandibles and dorsal maxillae in a ventral muscularized pharynx. The origin of Eunicida dates back to the late Cambrian, and the peaks of jaw morphology diversity and number of families are in the Ordovician. Species richness is heterogeneous among the seven recent families, with more than half of the valid species belonging to the Eunicidae + Onuphidae clade, one of the latest clades to diverge. Eunicidans inhabit soft and hard substrates from intertidal to deep waters in all oceans. The few freshwater species are restricted to Histriobdellidae, a family exclusively commensal/parasite of crustaceans. The reproductive biology, development and ecology of most families are poorly known and the information available suggests low dispersal ability. However, all families have records of widely distributed species. Scrutiny of these wide distributions has often revealed the presence of exotic species or more than one species. The exploration of the deep-sea and of new habitats has led to recent descriptions of new species. Furthermore, the revision of type specimens, the examination of new morphological features and the use of molecular data have revealed hidden biodiversity under unjustified synonyms, poor understanding of morphological features and incomplete descriptions. Molecular studies are still very few or nonexistent for the families Histriobdellidae, Hartmaniellidae, Lumbrineridae and Oenonidae. The integration of new methodologies for morphological and molecular study, along with information on biological and ecological traits appears to be the path to improve the knowledge on the diversity of Eunicida.

Abstract:

ABSTRACT. Introduction: The polychaete fauna inhabiting Chinchorro Bank has been poorly studied and only 35 species have been previously reported. Objective: To examine the taxonomic composition of the Eunicida and Amphinomida associated to dead coral substrates from this coral reef atoll, a Biosphere Reserve located in the southern Mexican Caribbean. Methods: In April 2008, dead coral fragments of the genus Porites were manually collected by SCUBA diving at eight stations between 4-16.2 m depth. Results: A total of 714 individuals belonging to 17 genera and 48 species of the families Amphinomidae, Dorvilleidae, Eunicidae, Lumbrineridae, Oenonidae and Onuphidae were identified. Eunicidae was clearly the more diverse (29 species; 60.4 %) and abundant family (479 individuals; 67.1 %), while the Oenonidae and Onuphidae were represented by only one individual-species each. Thirty-eight species (79.2 %) were new records for Chinchorro Bank, of which 23 species (47.9 %) were newly reported for the Western Caribbean ecoregion. Conclusions: The polychaete fauna recorded showed that the Chinchorro Bank reef is a species-rich habitat that deserves further study; the 48 species from six families identified were similar or even greater than the number of species reported from dead coral environments of other Caribbean Sea regions.

Abstract:

Two new species of Marphysa Quatrefages, 1865 (Polychaeta: Eunicida: Eunicidae), M. bulla n. sp. and M. maxidenticulata n. sp., are described from the northern coast of China with comments on the usefulness of pectinate chaetae to separate species. A redescription of Marphysa orientalis Treadwell, 1936 originally described from China is given. The genus Marphysa is widely collected for bait for recreational fishermen and anglers in China and is also exported to Australia and Japan, yet the number of species involved or their native distribution are currently unknown. It is critical that aquaculture programs know which species they are attempting to breed and their native distributional ranges. A key to all described species of Marphysa from China, including two new species described in this paper is given.

Abstract:

AbstractThe present study is the first attempt to describe beta-diversity patterns in polychaetes of the Caribbean Sea, analysing depth changes in species composition of the Eunicida and Amphinomida inhabiting dead coral in Chinchorro Bank, southern Mexican Caribbean. In April 2008, dead coral fragments were collected by scuba diving in eight stations along two bathymetric gradients (4–9 m and 7–16.2 m depth); 755 individuals from 53 species of the families Amphinomidae, Dorvilleidae, Eunicidae, Lumbrineridae, Oenonidae and Onuphidae were identified. The highest number of species (32) and individuals (514) were found in the family Eunicidae. The Northern transect harboured 36 species, on average 18.75 ind. L−1, which decreased linearly with depth; the Central transect had 43 species, on average 19.01 ind. L−1, which increased at middle depths. The species inhabiting both these zones were moderately different (βsor = 0.603): 49.06% of the fauna occurred on both transects, but the components of beta-diversity, turnover and nestedness, displayed distinct patterns: in the Northern one replacement was the dominant factor (βsim = 0.3–1; βnes = 0–0.091), practically representing all faunal differences (βsor = 0.391–1); in the Central, dissimilarity due to nestedness increased (βnes = 0.031–0.829), mainly at the shallowest stations, but from 5 m depth, beta-diversity was almost completely explained by species replacement (βsim = 0.417–0.5; βnes = 0.031–0.318). Faunal differences were mostly related to higher abundances of Lysidice caribensis, Eunice goodei and Lumbrineris floridana in the Northern zone, and Lumbrineris perkinsi, Nicidion obtusa, Lysidice caribensis, Lumbrineris floridana, Lysidice unicornis and Eunice mutilata in the Central zone.

Abstract:

A new species of the Marphysa sanguinea group, M. iloiloensis n. sp. (Annelida: Eunicida: Eunicidae), is described from the Marine Annelids Hatchery of the Southeast Asian Fisheries Development Center, Aquaculture Department (SEAFDEC- AQD), Iloilo Province, Philippines. It represents the first record of this group in the Philippines. The new species is most similar morphologically to M. hongkongensa Wang, Zhang & Qiu, 2018, but can be distinguished from it by having fewer branchial filaments, a pair of faint eyes (absent in M. hongkongensa), and in slight differences in jaw morphology and chaetation. The embryos of the new species develop inside a jelly cocoon attached to the entrance of the adult burrow; this is the first time that egg-containing cocoons have been found in any species of the sanguinea-group. Phylogenetic analysis based on the mitochondrial gene cytochrome c oxidase subunit I (COI) revealed that Marphysa iloiloensis n. sp. is genetically distinct from all other analysed Marphysa species and forms a sister group to M. hongkongensa. A revised identification key to members of the sanguinea-group in Southeast Asia is provided.

Abstract:

The diversity and distribution of polychaete species under the families Nereididae, Syllidae and Eunicidae in sub-tidal fouling assemblage was studied by submerging wood as test substratum. Wooden panels were fitted onto a raft and submerged in Kudankulam coastal waters (south east coast of India) in pre-monsoon, monsoon and post-monsoon seasons from May 2003 to July 2005. Panels (in replicate) were retrieved from the raft at 15-day intervals. A total of 24 polychaete species belonging to the three families were identified from the test panels.Perinereis cultrifera,Platynereis dumerilii,Syllis variegata,Syllis truncata, andEunice australiswere the dominant species observed on the test panels. The abundance of major polychaete group was varied considerably between the panel series submerged in May 2003 (post-monsoon), November 2003 (monsoon) and July 2004 (pre-monsoon). The major difference in the polychaete community structure was the low abundance of both nereidids on pre-monsoon season panels and the eunicids on monsoon and post-monsoon season panels.

Abstract:

Through SEM observations a probable sense organ located at the base of the ventral side of each dorsal cirrus in some eunicid polychaetes is described. This organ is externally characterized by numerous long ciliary projections. Similar structures are also found on corresponding positions in species belonging to other family groups in the Order Eunicida but in the Order Phyllodocida were found only in Aglaophamus sp. This species also has a similar structure, with ciliary projections, at the ventral base of each dorsal cirrus. However, the situation is quite different from any Eunicida species in that numerous bundles of ciliary projections are also scattered on the lateral sides of the body. Although the function of the ciliated organ of eunicids still remains unknown, a brief TEM observation of this organ on Marphysa sanguinea clearly shows that this organ is a sensory receptor and seems to suggest that it serves as a chemoreceptor rather than a mechanoreceptor.

Cacing laut merupakan salah satu jenis pakan alami yang banyak digunakan sebagai pakan induk udang di pembenihan udang. Jenis-jenis cacing laut yang dimanfaatkan sebagai pakan alami induk udang di pembenihan udang antara lain dari famili Nereidae dan Eunicidae. Famili Nereidae terdiri atas Nereis sp., Namalycastis, Perinereis nuntia. Famili Eunicidae terdiri atas Marphysa sp.-1, dan Marphysa sp.-2. Berbagai jenis cacing laut tersebut mempunyai nama lokal yang berbeda-beda di beberapa wilayah seperti di Kabupaten Serang, Cilacap, Situbondo, dan Barru. Masyarakat setempat memperoleh cacing laut tersebut dari penangkapan di alam antara lain di kawasan mangrove, tambak, dan pantai. Pembenihan udang sebagai pengguna sangat mengharapkan cacing laut dapat dibudidayakan sehingga kebutuhan pakan alami tidak tergantung dari hasil penangkapan saja. Pembenihan udang telah siap menerima produksi cacing laut dari hasil budidaya jika cacing laut berhasil dikembangkan, hal ini menjadi peluang pasar yang menjanjikan sehingga potensi dan peluang sebagai salah satu komoditas penting untuk memenuhi kebutuhan pakan alami dalam industri akuakultur terpenuhi.

Abstract:

Members of one species of Leodice Lamarck, 1818, one species of Lysidice Lamarck, 1818, and another of Palola Gray in Stair, 1847 were found among material from rhodolith beds, collected off the states of Paraíba and Pernambuco, northeastern Brazilian coast. Of those species, one is new to science and the other two are new records for the state of Pernambuco, although their occurrence on neighbouring areas was already known. Leodice calcaricola sp. nov. resembles morphologically L. miurai (Carrera-Parra & Salazar-Vallejo, 1998) as members of both species share similar body size, moniliform prostomial appendages, similar numbers of branchial filaments (1–3 per branchia), and, especially, by having falcigers with bidentate blades on anterior chaetigers, and tridentate on posterior ones. These species differ, however, since specimens of L. calcaricola sp. nov. have distinctly shorter antennae and palps, homodont and heterodont pectinate chaetae, three types of aciculae and two subacicular hooks per midbody parapodium. The other two species which members were found on the rhodolith beds are Lysidice cf. unicornis (Grube, 1840) and Palola brasiliensis Zanol, Paiva & Attolini, 2000. We describe herein new species to science and provide a redescription for L. cf. unicornis because the Brazilian specimens of this species have never been formally described.

Abstract:

In a series of studies on eunicids, there were explicit or implicit indications that Eunice riojai described from the north-western Caribbean Sea, and Eunice sebastiani described from south-east Brazil, were synonyms. This was based upon a then recent monograph on the genus, and on the fact that some specimens were found in drifting wood which would explain the large geographical range. The study of some large specimens of E. sebastiani, collected at the type locality, shows that there are several relevant morphological differences between the two species and thus both species names must be regarded as distinct. In fact, E. sebastiani is unique in the genus because their maxillae V are bidentate. Furthermore, herein we re-describe these two species and re-evaluate some morphological features described in previous studies.

Abstract:

AbstractThe present study reports polychaetes that bore into limestone rocks along the east coast of the Aegean Sea (eastern Mediterranean). Rock materials were collected at two depth intervals (0–5 and 5–10 m) at 15 stations in four localities of Ildırı Bay. A total of 276 specimens belonging to 12 species and four families (Eunicidae, Spionidae, Cirratulidae and Sabellidae) were recorded. Specimens belonging to Dodecaceria and Pseudopotamilla were identified at the genus level, because they differ from described species, were few in number or were in poor condition. Dipolydora giardia is a new species to the marine fauna of Turkey. The most dominant and frequent family in the area was Eunicidae, followed by Spionidae. Lysidice ninetta and L. margaritacea comprised 59% of the total number of individuals. The number of species and individuals, and the diversity index did not change with regard to depth or locality. Two species assemblages were found in the area, mainly formed by Dipolydora and Lysidice species. The Lessepsian species, Palola valida, which is a new record for the Aegean Sea, occurred abundantly at the study sites, posing a risk of damage to limestone rocks in the Mediterranean Sea. The morphological features of the species identified at the generic level and the burrow structure of these species are presented. The burrow shapes of Palola siciliensis and P. valida were described for the first time in the present study; they constructed complicated galleries, including more than four entrances.

Abstract:

Bioerosion is a major destructive force by mechanisms of grazing and boring organisms harmful on coral reef. The name of crypto fauna is associated with colonies of dead coral due to their role as bioeroding that alter the physical structure of reefs. Analysis of the cryptic polychaetes, totally 874 individuals were collected belonging to eight families among these families Eunicidae (14 species) is the best represented families, varied from 6 to 14 species in all the stations, where as the least number of species and numbers were collected in Johinder nagar (16.66 %) and maximum abundant in Bcori (52.56 %). The mean density of all the three stations varied from 8.785 ± 9.175 (Bcori), 5.142 ± 5.545 (Breakwater) and 2.785 ± 4.370 Johinder nagar. During this survey most abundant species Lydice collaris (30.34 %) followed by Eunice afra punctata (16.66%), L.ninetta (10.68%) and E. antennata (10.25 %) in all the three stations. They accounted for up to 50 % of the total number of individuals collected on dead corals and hard substrates. This study to evaluate the knowledge of the coral inhabiting polychaete distribution and to assist forthcoming researchers to know the particular groups taxonomy and towards better understanding utilization, in coral patches of the Nicobar areas.DOI: http://dx.doi.org/10.3126/on.v10i1.7754

Abstract:

Mass spawning dates of nyale worms (Eunicidae) have been scientifically predictable since 2019. The month of spawning is consistently following the pattern of the February full moon, while the date of spawning is consistently on the 20th of the lunar calendar. There are particular years with February only spawning, March only spawning, and split spawning in both February and March. The existing prediction of the split spawning, however, was constructed with very little available data. The present study aimed to revisit the split spawning prediction using the Metonic cycle, a 19-year lunisolar cycle. The results show that the spawning prediction very much follows the Metonic Cycle. There are minor dates on split spawning to be revised, when February full moon rises on 14th February. The revised hypothesis is that split spawning is very likely to occur when the full moon rises between the 7th to 13th of February. When February full moon appears before the 7th of February, single spawning will take place on the fifth day after the March full moon. When February full moon befalls after the 13th of February, single spawning will occur on the fifth day after the February full moon. The revised prediction method has only 2 (two) deviances in 114 years of simulation dates. The present study is the first to suggest the link between Polychaete spawning patterns and the Metonic Cycle.

Abstract:

A new species of Marphysa is described from India using both morphology and molecular data. The new species, Marphysa madrasi, belonging to the Teretiuscula-group, is characterised by having antennae about 2x longer than the prostomium, maxillae II and IV with a relatively large number of teeth (Mx II with 8+9; Mx IV with 7+11), compound spinigers present on a large range of mid-body chaetigers (at least 83–159), and pectinate chaetae present from the first few anterior chaetigers. We discuss all the species of this genus lacking compound falcigers (i.e., those belonging to the Sanguinea-, Mossambica- and Teretiuscula-groups), which have been reported from India and compare them to our new species. Only two accepted species in these groups can be confirmed as occurring in India, M. madrasi n. sp. and M. gravelyi Southern, 1921. We provide a table that summarises the important characters useful to identify species in this group of Marphysa with compound spinigers.

Abstract:

The long discussion on the identity of the large Eunice species from the Adriatic and Mediterranean Seas is a result of the broader discussion on the identity and synonymy of Eunice roussaei and Eunice aphroditois. Here we show that the species occurring in the Adriatic Sea is Eunice roussaei and how this species can be differentiated from Eunice aphroditois; we also characterize the Mediterranean Eunice roussaei.

Abstract:

The eunicid polychaete Marphysa sanguinea was until recently believed to be a cosmopolitan species, with a distribution ranging from the south-west coast of England to the Pacific coast of America, and New Zealand and Australia in the western Pacific. However, there are many morphological and ecological inter-population differences that render the definitive identification of these numerous populations difficult. The recent designation of a neotype, together with a more detailed morphological description of specimens from the type locality in south-west England, has allowed the concept that M. sanguinea represents a series of cryptic species, to be investigated by examining populations of species previously referred to as Marphysa sanguinea. A new species Marphysa mullawa was described from Moreton Bay Queensland, Australia. In this paper we describe a new species from the western Cape of South Africa which has previously been referred to as ‘Marphysa sanguinea’, using an integrative approach combining morphological data, RAPD-PCR analysis and a study of the sperm ultra-structure. The South African species is a popular bait animal for local sea anglers and is heavily exploited throughout the western Cape. The RAPD-PCR analysis also demonstrates that populations referred to as ‘Marphysa sanguinea’ from other geographical locations studied have distinct genetic pools, providing further evidence that Marphysa sanguinea is not a cosmopolitan species and consists of a suite of cryptic species.

Abstract:

The reproductive cycle ofMarphysa sanguinea(Polychaeta: Eunicidae) was studied in the Lagoon of Tunis between May 2006 and May 2007.M. sanguineais a gonochoric species. There were no morphological differences between males and females, and spawning occurred without epitokal metamorphosis. Gonads are not well defined in either sex. The process of spermatogenesis takes place in the coelomic cavity. Mature males show all stages of spermiogenesis at any one time. The ovaries ofM. sanguineaconsist of coelomic germ-cell clusters surrounded by a thin envelope of follicle cells derived from the peritoneum. Germ cells in premeiotic and previtellogenic phases are observed in one cluster. In each cluster the more differentiated oocytes detach and float free in the coelomic cavity where they undergo vitellogenesis as solitary cells. The cytoplasmic material of the mature oocytes (diameter superior to 200 μm) is asymmetrically distributed; large lipid droplets and large yolk spheres occupy the vegetal pole of the oocyte while smaller yolk spheres are situated in the animal hemisphere. The female coelomic puncture has a heterogeneous aspect and shows different oocyte diameters. The reproductive period is more intense in winter period from January to March. Spawning occurs mainly in April.

Abstract:

A taxonomic survey of Marphysa species (Polychaeta: Eunicida: Eunicidae) from coastal regions of northern Australia including recently collected specimens from a fish farm near Darwin, yielded three species: M. mullawa Hutchings & Karageorgopolous, 2003, a first record from northern Australia; M. mossambica (Peters, 1854; was Nauphanta mossambica), first confirmed record from Australia; and a new species, M. fauchaldi. The new species was recorded from intertidal muddy shores as well as in the sediments of fish farm ponds, where it was extremely abundant. It is characterised by a unique combination of chaetal features. A newly proposed informal subgroup of Marphysa, the Teretiuscula-group, is erected to contain the new species and other Marphysa species that share the possession of compound spinigerous chaetae in anterior parapodia only and the peculiar behaviour of encapsulating embryos in jelly cocoons. Morphologically, the new species falls between a group of Marphysa species having only compound spinigers and the recently resurrected genus Nauphanta, which completely lacks compound chaetae. The discovery of this new species necessitated a re-evaluation of the morphological features of Nauphanta and Marphysa species lacking falcigers, in particular homology of fan chaetae, the only apparent synapomorphy of Nauphanta. Fan chaetae appear to be a specialised type of pectinate chaetae, which are found also in species of Marphysa including the new species. Based on this finding, and an evaluation of other characters, Nauphanta is returned to synonymy with Marphysa. Further, an analysis of size-related variation of key morphological characters in M. mossambica and comparison with those in the types of M. novaehollandiae (Kinberg, 1865; formerly Nauphanta) and M. simplex Treadwell, 1922, indicated that both species should be synonymised with M. mossambica. A key is provided to identify Marphysa species of the Indo-west Pacific.

A new species of Eunicidae, Eunice decolorhami sp. n., from the southeastern Pacific Ocean, is described. The species was collected at the slope of the Desventuradas Islands (San Félix and San Ambrosio) and in three nearby seamounts of the Nazca Ridge, in dead coral rubble bottoms from 180 to 340 m depth and inhabiting inside parchment-like branched tubes. Eunice decolorhami sp. n. can be distinguished from other species of the genus, mainly by the coloration pattern of the subacicular hooded hooks along the body segments, the beginning of the subacicular hooded hooks, the beginning of the branchiae, the maximum number of branchial filaments, and the maxillary formula. A key for the seven Eunice species recorded off the coast of Chile and Peru, including the new species described herein, is provided.

Abstract:

A vast polychaete fauna is hidden behind complexes of cryptic and pseudo-cryptic species, which has greatly hindered our understanding of species diversity in several regions worldwide. Among the eunicids, Marphysa sanguinea Montagu, 1813 is a typical example, recorded in three oceans and with various species considered its junior synonyms. In South Africa, specimens previously misidentified as M. sanguinea are now known as Marphysa elityeni Lewis & Karageorgopoulos, 2008. Of the six Marphysa Quatrefages, 1865a species recorded from the same region, three have their distributions restricted to South Africa while the others are considered to have worldwide distributions. Here, we evaluated the taxonomic status of the indigenous M. elityeni and investigated the presence of the widespread species Marphysa macintoshi Crossland, 1903 and Marphysa depressa Schmarda, 1861 in South Africa using morphological and molecular data. Our results reveal that M. elityeni is a junior synonym of Marphysa haemasoma, a species previously described from South Africa which is herein reinstated as a valid species. Both M. macintoshi and M. depressa are not present in South Africa and their status as being distributed worldwide deserves further investigation. Marphysa durbanensis Day, 1934 and the new species described here, M. sherlockae n. sp., had been misidentified as M. macintoshi and M. depressa respectively. Thus, the number of Marphysa species with distributions restricted to South Africa increased from three to five. This study reiterates the importance of implementing an integrated taxonomic framework to unravel local biodiversity.
