Eunicidae

Abstract: Fauchald, Kristian. A Review of the Genus Eunice (Polychaeta: Eunicidae) Based upon Type Material. Smithsonian Contributions to Zoology, number 523,422 pages, 117 figures, 53 tables, 1992.—The genus Eunice has been widely reported in all kinds of marine environment. A total of 286 names have been applied to taxa originally described in, or subsequently referred to, the genus. All such taxa published prior to 1985 have been accounted for below. Of these, some or all types of about 175 are available and are described below. Twenty-five species are incompletely known; types are missing and original descriptions (or subsequent descriptions of types) are insufficient to relate these species to the rest. The descriptions of these species have been briefly summarized. A key to species includes nearly all species for which types were available. Species considered incompletely known are excluded from the key, but are included when possible in a set of tables comparing similar species. Forty-seven named taxa are indeterminable. Twenty-two have been referred to other genera, including some new combinations. In some cases the type lot included two species; some of these types could be referred to other, known species; however, four species are described as new. Seven species have been given new names for nomenclatural reasons. Attempts to group the 206 reasonably well-characterized species into supra-specific taxa using cladistic techniques did not lead to interpretable results. The reasons might include the very large number of species compared to the number of characters. A detailed analysis of the characters has been started using freshly collected material in an attempt to expand the number of characters and measure the variability of currently used characters. Similar reviews are planned for the remaining eunicean genera.

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: Species traditionally considered to belong to Eunice are now, also, distributed in two other genera Leodice and Nicidion recently resurrected to reconcile Eunicidae taxonomy with its phylogenetic hypothesis. In Australia, Eunice species have been reported from all seas and sum up to 22 species. In this study, we propose 10 new combinations for traditional Eunice species, which should be moved to Leodice; describe seven new species, four of Eunice and three of Leodice; and comment on species previous recorded from the Australian Coast. Previous records of E. denticulata, E. filamentosa, E. grubei, E. indica, E. longicirris, E. microprion, E. paupera, E. tridentata, E. tubifex and E. vittata from Australia are considered dubious. Eunice tribranchiata, originally described from Australian specimens, is considered here to be an indeterminable species. This study also includes descriptions of Eunice, Leodice and Nicidion as well as key to these genera and their species recorded from Australia.

Abstract: 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 Felix 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.
