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.

Pachypops is a South American freshwater sciaenid genus characterized by having two anal-fin spines, three mental barbels, an inferior mouth, a swimbladder with a pair of short appendages anteriorly and a pair of longer appendages projected posteriorly, and the haemal spine of the first caudal distinctly expanded. Three valid Pachypops species are recognized herein. Of the six nominal species previously assigned to Pachypops, two are herein recognized as valid (Perca fourcroi and Micropogon trifilis), two are assigned to other sciaenid genera (Pachypops adspersus and Pachypops cevegei) and two are considered junior synonyms (Corvina biloba and Pachypops camposi). A seventh nominal species, Pachyurus nattereri, formerly considered a valid species of Pachyurus, is determined to be a junior synonym of Pachypops fourcroi, and lectotype and paralectotypes are designated for it. Pachypops fourcroi occurs in the Orinoco, Amazonas, Essequibo, Corantijn, and Approuague River basins, and Pachypops trifilis in rivers of Guyana and middle and lower reaches of the Rio Amazonas basin. A third valid species, Pachypops pigmaeus n. sp., is herein described from tributaries of the Rio Amazonas, Brazil.

AbstractAlloxysta Förster, 1869 (Hymenoptera: Figitidae) type material of 19 nominal species deposited in the Canadian National Collection of Insects (Ottawa, Ontario, Canada) and the United States National Museum of Natural History (Washington, District of Columbia, United States of America) were studied. Nine species are treated as valid: A. australiae (Ashmead, 1900), A. commensuratus Andrews, 1978, A. japonicus (Ashmead, 1904), A. lachni (Ashmead, 1885), A. longiventris Baker, 1896, A. minuscula Andrews, 1978, A. nothofagi Andrews, 1976, A. vandenboschi Andrews, 1978, and A. xanthopsis (Ashmead, 1896). The following synonymies are established: A. affinis (Baker, 1896) and A. quebeci Andrews, 1978 junior synonyms of A. castanea (Hartig, 1841); A. alaskensis Ashmead, 1902 and A. coniferensis Andrews, 1978 junior synonyms of A. macrophadna (Hartig, 1841); A. bicolor (Baker, 1896) and A. anthracina Andrews, 1978 junior synonyms of A. obscurata (Hartig, 1840); A. dicksoni Andrews, 1978 junior synonym of A. pilipennis (Hartig, 1840); and A. leguminosa (Weld, 1920), A. megourae (Ashmead, 1887), and A. rauchi Andrews, 1978 junior synonyms of A. brevis (Thomson, 1862). The type material of A. schlingeri Andrews, 1978 and A. halli Andrews, 1978 could not be found and we consider them as nomina dubia. Alloxysta vandenboschi Andrews is removed from synonymy with A. obscurata and considered a valid species. Comments on the type material are given. Complete redescriptions and images are presented for the valid species.

The Family

The family Plectopylidae is divided into two subfamilies: Sinicolinae subfam. nov. (included extant genera: Gudeodiscus Páll-Gergely, 2013, Endothyrella Zilch, 1959, Halongella Páll-Gergely, 2015, Sicradiscus Páll-Gergely, 2013, Sinicola Gude, 1899) and Plectopylinae Möllendorff, 1898 (included genera: Chersaecia Gude, 1899, Hunyadiscus Páll-Gergely, 2016, Naggsia Páll-Gergely & Muratov, 2016, Plectopylis Benson, 1860). The Eocene fossil Plectopyloides Yen, 1969 is classified into the Sinicolinae. The Plectopylinae are revised mainly based on historical type and non-type material, and the material of the Florida Museum of Natural History, collected in Thailand in the 1980s. The following species-group taxa are described as new: Chersaecia auffenbergi sp. nov., Chersaecia densegyrata sp. nov., Chersaecia mogokensis sp. nov., Chersaecia reversalis sp. nov., Chersaecia scabra sp. nov., Chersaecia shiroiensis subnagaensis subsp. nov., Hunyadiscus tigrina sp. nov., Naggsia oligogyra sp. nov., Plectopylis crassilabris sp. nov., Plectopylis malayana sp. nov. and Plectopylis thompsoni sp. nov. The genus Endoplon Gude, 1899 is treated as a synonym of Chersaecia. Consequently, the two species classified in Endoplon are members of Chersaecia: Chersaecia brachyplecta (Benson, 1863) comb. nov. and Chersaecia smithiana (Gude, 1897) comb. nov. The genus Plectopylis is redefined, and includes only species with fused anterior and posterior lamellae. Thus, the following species are moved from Plectopylis to Chersaecia: Chersaecia feddeni (Blanford, 1865) comb. nov., Chersaecia goniobathmos (Ehrmann, 1922) comb. nov., Chersaecia leucochila (Gude, 1897) comb. nov., Chersaecia magna (Gude, 1897) comb. nov. and Chersaecia woodthorpei (Gude, 1899) comb. nov. Altogether thirteen species and varieties are moved to the synonymy of valid species: Helix (Plectopylis) brachydiscus Godwin-Austen, 1879 syn. nov., Helix (Plectopylis) ponsonbyi Godwin-Austen, 1888 syn. nov., Plectopylis (Chersaecia) kengtungensis Gude, 1914 syn. nov., Plectopylis (Chersaecia) degerbolae Solem, 1966 syn. nov., Plectopylis lissochlamys Gude, 1897 syn. nov., Helix repercussa Gould, 1856 syn. nov., Plectopylis achatina var. obesa Gude, 1898 syn. nov., Plectopylis achatina var. infrafasciata Gude, 1898 syn. nov., Plectopylis achatina var. venusta Gude, 1898 syn. nov., Plectopylis achatina var. castanea Gude, 1898 syn. nov., Plectopylis achatina var. breviplica Gude, 1898 syn. nov., Plectopylis achatina var. repercussoides Gude, 1899 syn. nov., Plectopylis linterae var. fusca Gude, 1898 syn. nov. Plectopylis (Chersaecia) simplex Solem, 1966 is a subspecies of Chersaecia perarcta (Blanford, 1865), whereas Plectopylis muspratti Gude, 1897 is a subspecies of Chersaecia nagaensis (Godwin-Austen, 1875).

The hydrozoan genus Zyzzyzus is revised based on reexaminations of all available type specimens and on additional material. The taxon includes four valid species: Zyzzyzus spongicolus (von Lendenfeld, 1884), from the eastern Indian and southwest Pacific oceans; the type species, Z. warreni Calder, 1988, from the Atlantic, western Indian, and western Pacific oceans; and Z. floridanus Petersen, 1990 and Z. robustus Petersen, 1990, both from the northwest Atlantic. Although type specimens of Z. calderi Petersen, 1990 could not be located, it has been assigned here to the synonymy of Z. warreni because of similarities between the two in nematocyst dimensions, in number and structure of endodermal canals, and in external morphology of the hydrocaulus and hydrorhiza. A sixth nominal species (Corymorpha iyoensis Yamada, 1958) has on one occasion been assigned to the genus, but detailed studies of the type material are needed to resolve its taxonomic affinities.

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

Emended Description

Abstract The type species of Trophomera, T. iturupiensis, is redescribed from type material and important errors in the original description corrected. As a result of this emended description, Benthimermis is proposed as a junior synonym of Trophomera and its species transferred accordingly. The family name Benthimermithidae is retained according to articles 23.1 and 40.1 of the International Code of Zoological Nomenclature. Trophomera is diagnosed and an annotated list of nominal species presented. Trophomera litoralis sp. n., collected from the tidal zone of Ushishir Island (Kuril Archipelago), is described on the basis of four males. The males of T. litoralis sp. n. differ from those of other Trophomera species primarily by the much higher number of precloacal supplementary organs (105-108 vs 2-68). Trophomera litoralis sp. n. is most similar to T. regalis comb. n. yet differs by shorter body length (5.8-9.3 vs 14.9 mm), body proportions (a = 67-107 vs 124.4; c = 61-97 vs 135.7), greater length of the intermediate spermatoduct between the anterior and posterior testes (ca 1/7th vs ca 1/140th of body length), tail shape (rounded conoid vs pointed conoid), and number of precloacal supplementary organs (105-108 vs 49).

Type Population

Summary The type population of Meloidogyne polycephannulata is synonymised with M. incognita based on morphological and morphometric characters, as well as biochemical, molecular and phylogenetic studies. Morphological variability and a wide host range were reported for M. incognita during its first description and later re-description. Meloidogyne polycephannulata was described in Brazil from specimens collected in a carrot field (type population). The esterase phenotype (Est) characterised for this species was identical to the phenotype Est I2 of M. incognita, the most ubiquitous phenotype used for diagnostics. Morphological and morphometric characters of the descriptions of the two nominal species showed major similarities, as well as variability within the range of variation detected in M. incognita. In PCR assays, three SCAR markers species-specific for M. incognita (incK14 F/R, Mi/FR and incB06 F/R) amplified the same fragments of 399 bp, 955 bp and 1200 bp, respectively, for populations in both species. In phylogenetic studies based either on concatenated sequences of ITS1-5.8S-ITS2, D2-D3 rRNA, mitochondrial COII regions or on RAPD and AFLP data, the populations of both species grouped in the same clade with high bootstrap support. Altogether, these results provide congruent evidence that the M. polycephannulata type isolate deposited at the Embrapa Cryopreserved National Collection of Root-knot Nematodes is not a valid species but rather a junior synonym of M. incognita.

Recently, we (Akkari & Enghoff 2011) described a new species of the genus Rharodesmus Schubart, 1960, discussing the taxonomic state of the family Pyrgodesmidae and providing notes on the four genera occurring in the west Palaearctic area. However, we failed to present details on the holotype of the new species, which we now provide in this note in order to make the species name available. Thus, we describe here the new species Rharodesmus tabarkensis Akkari & Enghoff by reference to the full description given in Akkari & Enghoff (2011) with the following information on the type material: Holotype ♂, TUNISIA, NW, Jendouba Governorate, Tabarka, N36°57.8, E8°44.6, alt. < 40 m, coastal slope below the Genoese fort, under stones, 9.iii.2009, N.

The parasitic isopod family Cymothoidae Leach, 1818 of the India exclusive economic zone is reviewed. A total of 56 nominal species corresponding to 48 valid species belonging to sixteen genera are reviewed from 73 host species belonging to 35 families. Mothocya plagulophora (Haller, 1880), Nerocila depressa Milne Edwards, 1840, Nerocila loveni Bovallius, 1887, Nerocila trichiura (Miers, 1877), Norileca triangulata (Richardson, 1910) and Ryukyua globosa Williams & Bunkley-Williams, 1994 are redescribed. Indusa pustulosa Pillai, 1954 is synonymised with Agarna malayi Tiwari, 1952; Cymothoa krishnai Jayadev Babu & Sanjeeva Raj, 1984 is synonymised with Cymothoa eremita (Brünnich, 1783) and Nerocila priacanthusi Kumari, Rao & Shyamasundari, 1987 is synonymised with Nerocila arres Bowman & Tareen, 1983. Ourozeuktes bopyroides (Lesueur, 1814) is revised and excluded from the Indian fauna. The Indian cymothoid species Agarna bengalensis Kumari, Rao & Shaymasundari, 1990, Cymothoa asymmetrica Pillai, 1954 and Nerocila hemirhamphusi Shyamasundari, Rao & Kumari, 1990 are regarded here as species inquirenda. A key to the Indian genera of the family Cymothoidae and keys to the Indian species of the genera Cymothoa, Joryma, Mothocya, and Nerocila are presented. A checklist of the valid Cymothoidae species until now reported from Indian marine fishes are compiled. Host preferences, morphological variability and distribution are discussed.

A taxonomic conspectus is presented for the genus Oxysarcodexia Townsend, 1917, which is one of the most species-rich genera of New World flesh flies. It has its center of diversity in the Neotropical Region, with some species reaching into the Nearctic and a few species introduced to the Australasian and Oceanian Regions. Species within this genus are primarily dung-breeders, but some species have also been bred from vertebrate carcasses. Oxysarcodexia is defined and diagnosed, and a diagnosis, distributional data and known biological data are provided for each species together with figures of the habitus and male terminalia. Oxysarcodexia currently comprises 91 valid species, including six species newly described herein: O. alectoris sp. n. (French Guiana), O. angulosa sp. n. (Costa Rica), O. ariozanoi sp. n. (Brazil), O. graminifolia sp. n. (Colombia and Ecuador), O. maiae sp. n. (Ecuador), and O. rimata sp. n. (Ecuador). Two nominal species based on a male holotype, Oxysarcodexia bomplandi (Hall, 1937) and O subsericans (Walker, 1858), were left unidentified pending examination of their terminalia. Four nominal species, O. aureiceps (Macquart, 1855), O. dorisae Dodge, 1965, O. flavifrons (Macquart, 1846) and O. neivae Mattos, 1919, all described solely based on females, are considered of uncertain status pending a comprehensive study of females of this genus. Asioboettcheria Verves, 2001 is proposed as a junior synonym of Oxysarcodexia Townsend, 1917, syn. n., Oxysarcodexia cuernavaca Dodge, 1966 is proposed as a junior synonym of O. ventricosa (Wulp, 1895), syn. n., and Stackelbergeola papei Nandi, 1994 is proposed as a junior synonym of O. thornax (Walker, 1849), syn. n. A lectotype is designated for Sarcophaga varia Walker, 1836 [= O. varia (Walker, 1836)]. The newly-described O. ariozanoi and O. maiae are included in the “xon group” (former “Xarcophaga group”). New country-level distributional records are provided for O. adunca Lopes, 1975 (Ecuador), O. berlai Lopes, 1975 (Peru), O. cocais Carvalho-Filho, Sousa & Esposito, 2017 (Argentina), O. insolita Lopes, 1946 (Ecuador), O. jamesi Dodge, 1968 (Costa Rica), O. marina (Hall, 1938) (Brazil), O. nitida Soares & Mello-Patiu, 2010 (Ecuador), O. notata Soares & Mello-Patiu, 2010 (Brazil and Ecuador), and O. terminalis (Wiedemann, 1830) (Paraguay).
