Long-bodied polynoids, like Polyeunoa laevis McIntosh, 1885 and similar species which are often associated with cold-water corals, are regularly reported from Antarctic, Subantarctic and adjacent cold-temperate waters. The taxonomy ofthese species is confused and has been subject to various discussions in the past. For the revision presented here weexamined the available type material and additional specimens of the following species: Polynoe antarctica Kinberg,1858, Polyeunoa laevis McIntosh, 1885, Enipo rhombigera Ehlers, 1908, Hololepidella flynni Benham, 1921, Polyeunoedubia Hartmann-Schröder, 1965, Polyeunoa monroi Averincev, 1978, and Polynoe thouarellicola Hartmann-Schröder,1989. As a result we consider Polyeunoa laevis McIntosh, 1885, Parapolyeunoa flynni (Benham, 1921) n. comb., andNeopolynoe antarctica (Kinberg, 1858) n. comb. as valid species. Enipo rhombigera Ehlers, 1908, Polyeunoe dubiaHartmann-Schröder, 1965, and Polynoe thouarellicola Hartmann-Schröder, 1989 are junior synonyms of Polyeunoalaevis. Polyeunoa monroi Averincev, 1978 is a junior synonym of Hololepidella flynni Benham, 1921 for which the newgenus Parapolyeunoa n. gen. is erected. Polynoe antarctica Kinberg, 1858 is transferred to the genus NeopolynoeLoshamn, 1981 and represents the third known species within this genus. Three comprehensive tables illustrating the distinctive characters of the considered genera and species are given to facilitate the identification of the valid species.Keywordstaxonomy, Polyeunoa, Parapolyeunoa n. gen., Neopolynoe, Southern Ocean, SOAP workshop, cold-water corals

The Family

This is the first comprehensive taxonomic review of the family Lycaeidae. This study is based primarily on the extensive collections of the Natural History Museum, Denmark (NHMD, formerly ZMUC) and the US National Museum of Natural History, Smithsonian Institution, Washington DC, USA (USNM), and on additional material from the South African Museum (SAM) and in the South Australian Museum (SAMA). The two currently recognized genera in the family, Lycaea Dana, 1852 and Simorhynchotus Stebbing, 1888, are maintained with the latter still regarded monotypic with S. antennarius (Claus, 1871). Characters used to distinguish species in the past are re-evaluated in order to determine their validity. There are 15 nominal species of Lycaea in the literature, excluding Pseudolycaea pachypoda Claus, 1879 and Metalycaea globosa Stephensen, 1925. Pseudolycaea Claus, 1879 is regarded a synonym of Lycaea, as confirmed by this study, and M. globosa is a junior synonym of L. serrata Claus, 1879, as demonstrated by an examination of the type material. Of the remaining nominal species many have been synonymized with L. pulex Marion, 1874 in the past, often based on erroneous literature references. Thus, the taxonomic status of all nominal species was redetermined by the examination of type material or from the original literature reference if type material could not be found. In conclusion, ten species of Lycaea are recognized as valid, including three described as new. Lycaea bovallii Chevreux, 1900 is determined to be a valid species with the following as junior synonyms, L. gracilis Spandl, 1924, L. bajensis Shoemaker, 1925 and L. bovallioides Stephensen, 1925. It seems to be widely distributed and relatively common in the tropical regions of all the world’s oceans, including the Mediterranean Sea. The other species recognized as valid are L. lilia Volkov, 1982; L. nasuta Claus, 1879; L. pachypoda (Claus, 1879); L. pulex Marion, 1874 (L. robusta Claus, 1879, L. similis Claus, 1879 and L. pauli Stebbing, 1888 regarded junior synonyms); L. serrata Claus, 1879 and L. vincentii Stebbing, 1888 (Amphipronoe longicornuta Giles, 1888 a junior synonym). In addition, three species are described as new to science; L. intermedia sp. nov., L. proserrata sp. nov. and L. osbornae sp. nov. All were found in the tropical regions of the Atlantic, Pacific and Indian Oceans; the former two are relatively common and widespread. All species are described and illustrated and a key is provided to facilitate their identification.

ABSTRACT Hyphessobrycon itaparicensis was originally described from a small stream in the Itaparica coastal island, Bahia State, Brazil, and has been sampled in several coastal rivers draining Bahia and Sergipe States. Broad examination of type material and recently collected specimens resulted in the redescription provided herein. The presence of one humeral blotch, absence of pseudotympanum, and conservation aspects of H. itaparicensis are briefly discussed. Data obtained from the original description, paratypes and topotypes of H. sergipanus showed broad overlap with H. itaparicensis and absence of morphological diagnostic features supporting the recognition of H. sergipanus as a valid species. Thus, H. sergipanus is considered as junior synonym of H. itaparicensis. We emphasize the need of examining large population samples and type material of similar congeners to avoid improper propositions of new specific names.

Late Osagean to Meramecian Platycrinites and Eucladocrinus from Illinois, Iowa, and Missouri are redescribed and redefined from study of type material. Three of the oldest species were incorrectly synonymized with P. sarae, and this correction leads to a realignment of species systematics within Platycrinites. Accordingly, six species of Platycrinites and one species of Eucladocrinus are considered valid in the Keokuk Limestone through St. Louis Limestone of the stratotype area. Valid species include Platycrinites saffordi (Hall), P. sarae (Hall), P. georgii (Hall), P. pumilus (Hall), P. brevinodus (Hall), P. niotensis (Meek and Worthen), and Eucladocrinus millebrachiatus Wahsmuth and Springer. Nomenclatoral changes include the following: 1) P. sarae is redescribed and all junior synonyms are removed; 2) P. georgii is a valid senior synonym of P. bonoensis (White), P. aeternalis (Miller), P. boonvillensis (Miller), and P. cauducus; 3) P. pentagonus (Miller) is a junior synonym of P. niotensis; 4) P. pumilus is a valid senior synonym of P. prattenanus (Meek and Worthen), and P. monroensis (Worthen); 5) P. bloomfieldensis (Miller) is designated as a nomen dubium; and 6) Eucladocrinus millebrachiatus immaturus is a junior synonym of E. millebrachiatus.The evoluton of new species in Platycrinites was by a combination of cladogenesis and possibly anagenesis. Platycrinites sarae evolved from P. saffordi possibly through anagenesis, P. pumilus evolved from P. niotensis through cladogenesis, and P. hemisphaericus evolved through cladogenesis from P. brevinodus, although P. hemisphaericus does not occur in the geographic area of this study.

Trichodischia Bigot, 1885 is a Neotropical genus with a confusing taxonomic history. This was initially composed of two species: T. caerulea Bigot, 1885 and T. soror Bigot, 1885. Later, the genus Trichoraea Cortés, 1974 was erected for T. caerulea. When reviewing the taxonomic history of both species, we discovered that both genera have been considered synonymous based on erroneous information and without a formal synonymy being proposed. Herein, we redescribed T. soror, provide images of adults and describe the male terminalia for the first time. In addition, by examining the type material, we propose Trichoraea as a junior synonym of Trichodischia, syn. nov., confirm T. caerulea comb. rest. and T. soror as valid species and provide some comments about the taxonomy and host record of the genus.

Type material of the described species of Ascopus Marshall, 1951, Oreosecus Marshall, 1950, Perarogula Hoffmann, 1963 and Rhadinocopes Hustache, 1931 was examined and their taxonomic status is discussed. Oreosecus Marshall, 1950 and Rhadinocopes Hustache, 1931 are proposed as junior synonyms of Tapinomorphus Hartmann, 1904, Perarogula Hoffmann, 1963 is proposed as a junior synonym of Ascopus Marshall, 1951. Rhadinocopes curvipes Hustache, 1931, R. echinatus Marshall, 1951 and Perarogula lamottei Hoffmann, 1963 are transferred as valid species to the genus Ascopus, Rhadinocopes alticola Hustache, 1939, R. orientalis Hustache, 1931 and Oreosecus porculus Marshall, 1950 are transferred as valid species to the genus Tapinomorphus. Lectotypes of Rhadinocopes orientalis Hustache, 1931 and Rhadinocopes alticola Hustache, 1939 are designated. Ascopus girardi sp. nov. from Guinea, Mt. Nimba, is described and compared with all other species of the genus. Male and female genitalia of Ascopus are described and illustrated for the first time. A key to Ascopus species is presented.

Both sexes of Anastatus mantoidae Motschulsky, the type species of Anastatus Motschulsky, 1859, and females of Anastatus echidna (Motschulsky), the type species of Cacotropia Motschulsky, 1863, the oldest junior synonym of Anastatus (Hymenoptera: Eupelmidae: Eupelminae), are redescribed and illustrated based on original type material and compared to more recently collected material. Anastatus mantoidae, previously known only from Sri Lanka, is newly reported from Indonesia (Java and Sumatra) and Thailand, and a very similar species, A. motschulskyi n. sp., is newly described based on both sexes from Malaysia (Sabah) and Thailand and compared to A. mantoidae. Anastatus echidna, also originally known only from Sri Lanka, is newly reported from India, Pakistan and Thailand, and potential synonymy of one or both of Anastatus amarus (Subba Rao, 1957) and Anastatus acherontiae Narayanan, Subba Rao & Ramachandra Rao, 1960, under A. echidna is discussed.

Two very similar species of the genus Chiloplacus, namely C. magnus and C. insularis, are re-described and compared based on type material as well as Iberian specimens. Relevant new information is obtained for their characterisation and for elucidating their identity with more accuracy. Special mention is deserved by the findings regarding: i) the morphology of the lateral field at vulval level; and ii) the location of the vulva, which is either midventral or subventral, two remarkable traits that were originally overlooked. Chiloplacus magnus is distinguished by having the left lateral field expanded at vulval level and the vulva displaced to a subventral position, whereas C. insularis displays the usual pattern of the genus. The evolutionary relationships of the Iberian C. magnus are explored by means of D2-D3 sequence analysis. Chiloplacus similis is regarded as identical to C. magnus and is proposed as a new junior synonym of the latter.

Here we present a description of a new aphid species—Uroleucon (Uroleucon) lebanonense sp. nov. associated with Tragopogon coloratus (Asteraceae) in Lebanon. Apterous and alate viviparous females of the new species are described and illustrated, and compared with the morphologically similar species Uroleucon (U.) mongolicum Holman, 1975. An identification key to Palaearctic Uroleucon species with three setae on the first tarsal segment is provided. On the basis of the re-examination of the type material, we propose to restore the valid species status of U. (U.) altaicum Szelegiewicz, 1982 bona species which was regarded as a synonym of U. mulgedii (Nevsky, 1928). Additionally, we propose transfer of U. (U.) altaicum, U. (U.) bielawskii (Szelegiewicz, 1962) and U. (U.) mulgedii to the subgenus Lambersius Olive.

In accordance with the rules in the International Code of Zoological Nomenclature, the type species for the genus Edessa Fabricius, 1803 is now recognized to be Cimex antilope Fabricius, 1798 rather than the previously recognized Cimex cervus Fabricius, 1787. Edessa antilope is redescribed, as well as the following four species that have in the past been related or compared to E. antilope: E. arabs (Linnaeus, 1758) from French Guiana, Costa Rica and Panama (new record), E. helix Erichson, 1848 from Costa Rica, Panama, Venezuela, Suriname (new record), Guyana, Brazil (new record), Bolivia (new record) and Argentina (new record), E. ibex Breddin, 1903 from Costa Rica, Panama (new record), Ecuador, Brazil (new record), Peru and Bolivia (new record), and E. taurina Stål, 1862 from Mexico, Guatemala, Belize (new record), Honduras (new record). The distribution of Edessa antilope is expanded to Venezuela. The female of E. antilope and the male of E. taurina are described for the first time. Edessa antilope is removed from the synonymy of E. arabs and reinstated as valid species; additionally, E. costalis Stål, 1872 is removed from the synonym of E. helix and is placed as a junior synonym of E. antilope. Edessa saiga Breddin, 1903 is considered a junior synonym of E. ibex. Lectotypes are designated for all species. A key is provided for the identification of the species.
