Revision of Comesomatidae (Nematoda)

The gross and fine morphology of the family Comesomatidae is reviewed and the systematic position of its members revised. Significant differentiating characters of the Comesomatidae within the Chromadorida are: a copulatory apparatus provided with apophyses, a female reproductive system with outstretched ovaries, the presence of marginal tubes within the oesophagus, and a non-sclerotized and enlarged tail tip. For classification within the family the following three main characters are used: the structure of the buccal cavity, the structure of the copulatory apparatus, and the arrangement of the cephalic sense organs. Structure of the Sabatieria type is considered basic. The genera are rearranged in three subfamilies as follows: Sabatieriinae ( Cervonema, Laimelia, Pierrickia, Sabatieria (syn. Actarjania), Scholpaniella ), Dorylaimopsinae (Dorylaimopsis (syn. Mesonchium), Hopperia, Metasabatieria, Paramesonchium, Vasostoma ), Comesomatinae ( Comesoma, Metacomesoma, Paracomesoma. ) Six species of Comesomatidae are described from the øresund, Denmark: Cervonema macramphis sp.n.; Laimelia filipjevi nom. nov. (syn. Sabatieria longicaudata Filipjev, 1922); Sabatieria hilarula De Man, 1922; S. ornata (Ditlevsen, 1918); S. punctata (Kreis, 1924); Dorylaimopsis punctata Ditlevsen, 1918. Representatives of these species constitute more than 40% of the total number of nematodes in the region.     

A revision of the genera Dirphys Howard and Encarsiella Hayat (Hymenoptera: Aphelinidae)

Abstract. Dirphys and Encarsiella are revised for the world, and include four and six species respectively. Three Dirphys and two Encarsiella species are described as new. Generic diagnoses and keys to world species of Dirphys and Encarsiella are provided, and their biology is reviewed. These genera are related to the large and economically very important genera Coccophagus and Encarsia , which between them contain about 400 currently valid species. Encarsiella was recently synonymized with Dirphys , and both have previously been confused with Coccophagus and Encarsia , adding to the difficulty surrounding the taxonomy of the latter genera. Computerized character analysis based on parsimony supports the reinstatement of Encarsiella as a valid genus and shows relationships between Dirphys, Encarsia and Encarsiella.     

Taxonomic revision of the genus Stauropoctonus Brauns, 1889 (Hymenoptera: Ichneumonidae: Ophioninae) in Japan

The Japanese species of the ichneumonid genus Stauropoctonus Brauns, 1889 are revised. As a result, three species are recognized. Stauropoctonus infuscus (Uchida, 1928 ) stat. rev. , previously synonymized with S. bombycivorus (Gravenhorst, 1829 ), is recognized as a valid species and re‐described. Stauropoctonus bombycivorus, which has already been recorded in Japan, is also recognized and re‐described based on Japanese specimens. Stauropoctonus aurantiacus sp. nov. is described based on a single male specimen from Yakushima Island, Kagoshima Prefecture, Japan. Stauropoctonus nigrithorax Lee & Kim, 2002 syn. nov. is newly synonymized with S. bombycivorus. Additionally, a key to the Stauropoctonus species and discussions on their phenology and collection methods are provided.     

Phylogenetic analysis of the scorpion genus Brachistosternus (Arachnida, Scorpiones, Bothriuridae)

A phylogenetic analysis of the scorpion genus Brachistosternus Pocock (Bothriuridae) is presented. The analysis is based on a data set including 38 of the 41 described species of Brachistosternus plus eight outgroup representatives of seven additional bothriurid genera and one buthid, scored for 116 morphological characters. The cladistic analysis of this matrix under implied weighting results in four most parsimonious trees. The monophyly of genus Brachistosternus is well supported; its subgeneric subdivision is redefined: the subgenera Brachistosternus Pocock and Ministernus Francke are considered valid, whereas Leptosternus Maury is synonymized with Brachistosternus . Illustrations of diagnostic structures are provided. The hemispermatophores of Brachistosternus peruvianus Toledo-Piza and Brachistosternus pegnai Cekalovic are illustrated for the first time. A key to species of Brachistosternus and maps with the distribution of the subgenera and main groups of species are provided.     

Chromadorida (Nematoda) from Guadeloupe and Polynesia with evidence of intersexuality

Spirobolbolaimus boucherorum sp.n. (Microlaimidac) and Sabatieria maboyae sp.n. (Comesomatidae) arc described, and Dorylaimopsis pellucidum (Cobb, 1920) is discussed. Intersex specimens have been found in all three species. Spirobolbolaimus boucherorum sp.n. is characterized by its multispiral amphidcal fovea, number and localization of the cervical setae arranged in six rows posterior to the amphids, and large banana-shaped sperm. Sabatieria maboyae sp.n., a member of the S. pulchra group, possesses long posteriorly located cervical setae and long spicules.     

A taxonomic revision of the genera Phrygionis Hübner and Pityeja Walker (Geometridae: Ennominae, Palyadini)

Phrygionis and Pityeja belong to the Palyadini, a tribe of neotropical Ennominae. The moths of both genera bear striking wing markings and mere variants were frequently described as species with the consequence that species diversity was overestimated. Numerous taxonomic changes are made in this work based on the study of primary types and much other material. Variation and distribution is recorded for each species and subspecies. Phylogenetic relationships within Phrygionis are examined, and comments are made on the evolution of wing pattern within this genus.
Fifteen full species are recognized in this study (13 in Phrygionis and two in Pityeja ), of which four (all in Phrygionis ) are described as new; 19 species-group (specific and subspecific) names refer to valid taxa. Twenty-four species-group names are synonymized (19 in Phrygionis and five in Pityeja ) and five are recombined with different genera (four with Phrygionis and one with Pityeja ). Three generic names are synonymized (one in Phrygionis and two in Pityeja ).     

Nematodes from the Strait of Magellan and the Beagle Channel (Chile): Description of four new species of the Comesomatidae

Four nematode species of the Comesomatidae from the Strait of Magellan and the Beagle Channel, Chile, are described as new to science. Comesoma hermani n. sp. can be separated from similar species, Comesoma bermudense Jensen & Gerlach, 1977, Comesoma minimum Chitwood, 1937 and Comesoma chilense Jensen & Gerlach, 1977 by the difference of body length, cephalic setae length, the ratio of the subcephalic setae to cephalic setae length and the ratio of spicule to anal body diameter. Dorylaimopsis magellanense n. sp. is identified by the lateral differentiation of 3–4 longitudinal rows of enlarged dots, the curved spicules are prominently jointed and with a ventral protrusion. Hopperia beaglense n. sp. could be easily recognised by both the rounded tail tip and anterior head end which differs from all the species of this genus except H. dorylaimopsoides (Allgén, 1959), which has, however, a smaller de Man ratio 'a' and reflexed ovaries. Hopperia arntzi n. sp. has a shorter body length which differs from the closest species, Hopperia americana Ward, 1984 and Hopperia muscatensis Warwick, 1973. Furthermore, the de Man ratio 'a' is different between our specimens and the other two species. An identification key to all known species of the genus Hopperia is provided.     

Revision of Trigonostomum Schmidt, 1852 (Platyhelminthes, Typhloplanoida, Trigonostomidae) with the description of seven new species

A morphological and taxonomic account of the genus Trigonostomum is provided. All known species are discussed and briefly re-described where necessary. Seven new species are described: T. franki from Curaçao, Florida (USA), the East African Coast and New Caledonia, T. nataschae from the French sub-Antarctic island Kerguelen, T. spinigerum from New Caledonia and T. watsoni from the Australian East Coast and New Caledonia. T. tori and T. galapagoensis , both formerly enclosed in T. setigerum , are considered new species, while T. australis also belongs to the same species group. Proxenetes denhartogi is transferred to Trigonostomum . Based on a comparison of old and new material, T. marki is synonymized with T. penicillatum , while T. prytherchi and T. divae are regarded as junior synonyms of T. lilliei ; T. intermedium and T. quadrifolium are considered synonyms of T. coronatum . Three species are considered species inquirendae : T. brunchorsti , T. piriforme and Marinellia lingulifera . Similarities and differences of the 17 valid species are discussed and summarized in an identification key.  © 2004 The Linnean Society of London, Zoological Journal of the Linnean Society , 2004, 141 , 271–296.     

Systematics and phylogeny of the caryophyllidia-bearing dorids (Mollusca, Nudibranchia), with descriptions of a new genus and four new species from Indo-Pacific deep waters

The phylogenetic relationships of the caryophyllidia-bearing dorids are studied, based on the examination of the type species of all the genera previously described. The phylogenetic hypothesis supports that the caryophyllidia-bearing dorids are a monophyletic group and the sister group of the clade formed by Astemnotus Ehrenberg, 1831 and Halgerda Bergh, 1880. Several genera previously considered as valid or regarded as uncertain are here synonymized: Peronodoris Bergh, 1904, Trippa Bergh, 1877, Phlegmodoris Bergh, 1878, Petelodoris Bergh, 1881, Kentrodoris Bergh, 1876, Audura Bergh, 1878, Centrodoris P. Fischer, 1883, Anisodoris Bergh, 1898, Awuka Er. Marcus, 1955, Rhabdochiia P. Fischer, 1883, Boreodoris Odhner, 1939, Dictyodoris Bergh, 1880, Gravieria Vayssiere, 1912, Aporodoris Ihering, 1886. The following genera are regarded as valid: Astemnotus, Atagema J.E. Gray, 1850, Jorunna Bergh, 1876, Platydoris Bergh, 1877, Diaulula Bergh, 1878, Rostanga Bergh, 1879, Halgerda Bergh, 1880, Baptodoris Bergh, 1884, Gargamella Bergh, 1894, Alloiodoris Bergh, 1904, Sclerodoris Eliot, 1904, Taringa Er. Marcus, 1955, Thorybopus Bouchet, 1977. The new genus Nophodoris is described based on two new species from New Caledonia deep waters. Two additional new species from New Caledonia belonging to the genera Atagema and Gargamella are also described. Nomenclatural and taxonomic problems are discussed, and several type species, neotypes and lectotypes are selected.     

Review of the family Anthribidae (Coleoptera) from the Jurassic of Karatau: Subfamily Protoscelinae. Genus Protoscelis Medvedev

The subfamily Protoscelinae from the Middle to Late Jurassic of Karatau is transferred from the family Chrysomelidae to the family Anthribidae. The genus Protoscelis, comprising five species, is reviewed. Males and females of the genus are described and keys to the identification of male and female specimens are provided. The new species P. medvedevi sp. nov. is described. The generic names Cerambyomima Medvedev, 1968, Pseudomegamerus Medvedev, 1968 and Protosceloides Medvedev, 1968 are synonymized under Protoscelis Medvedev, 1968, and the species Pseudomegamerus grandis Medvedev, 1968 is synonymized under Cerambyomima longicornis Medvedev, 1968. The new combinations Protoscelis longicornis (Medvedev, 1968) comb. nov. and P. nitidicornis (Medvedev, 1968) comb. nov. are established.     

A revision of the tribe Plectrothripini of fungus-feeding Thysanoptera (Phlaeothripidae: Phlaeothripinae)

Abstract The tribe Plectrothripini is redefined with examination of its systematic relationships. Keys are provided to the ten genera and forty-seven species in this tribe; one genus and eighteen species are newly described; one genus and two species are newly synonymized; two genera, Chiridothrips and Eurytrichothrips , are here removed from this tribe. The species of the tribe occur throughout the tropical and subtropical regions of the world; seventeen species are recorded from the Oriental Region, seventeen species from the Neotropical Region, ten species from the Afrotropical Region, two from Australia and one from the Pacific. They seem to be fungus-feeders, being found mainly under the bark of trees or on dead branches.     

The plam-feeding planthopper genus Ommatissus (Homoptera: Fulgoroidea: Tropiduchidae)

Abstract The tribe Trypetimorphini, the genus Ommatissus , and its two subgenera and eleven species are redescribed or described as new. Evidence for the monophyly of both the genus and of the tribe to which it belongs is examined; it is concluded that while the genus is monophyletic, the monophyly of the tribe is in doubt. Keys for the separation of the three genera of the tribe and for all of the known species of Ommatissus are presented. A new subgenus of Ommatissus is described: O.(Opatissus) , with the type-species O.vietnamicus . Four new species are described: Ommatissus magribus from Morocco, O.kamerunus from Cameroon, O.natalensis from South Africa and O.vietnamicus from Vietnam. The 'Dubas bug', Ommatissus lybicus Bergevin, formerly regarded as a variety of O.binotatus Fieber, is raised to full species status. Trichoduchus is synonymized with Trypetimorpha resulting in the new combinations Trypetimorpha biermani Dammerman, T.china Wu and T.japonicus Ishihara. Trichoduchus japonicus Fennah is synonymized with Trypetimorpha japonicus Ishihara.

On the phylogeny of Euryteinae (Crustacea,Copepoda, Cyclopoida), with description of one new species from Korea

Euryte koreana sp. nov. is described from the shallow littoral on the East Coast of South Korea, and represents the first record of the subfamily Euryteinae Monchenko, 1974 in the Pacific Ocean north of the tropics. It belongs to a group of species that have the caudal rami length/width ratio of around four, but differs from all congeners by a number of morphological features. Detailed drawings and extensive scanning electron micrographs of many characters of ornamentation provided for this species should serve as a benchmark for distinguishing closely related species in this subfamily with conservative macro-morphology. A morphologically distinct population from anchialine caves in Mallorca, identified previously as Euryte longicauda Philippi, 1843, is described as another new species: Euryte jaumei sp. nov. To test the phylogenetic relationships of its members and previous hypotheses about generic placement of two species associated with scleractinian corals, several cladistic analyses are performed on all 16 currently recognized species of Euryteinae and two outgroups, Neocyclops australiensis Karanovic, 2008 and Troglocyclops janstocki Rocha and Iliffe, 1994, using 25 morphological characters. All resulting trees suggest a close relationship between the two commensal species and them as a sister clade to all other Euryteinae. They are transferred into a newly erected genus Coraleuryte gen. nov., as C. bellatula (Humes, 1991) comb. nov. and C. verecunda (Humes, 1992) comb. nov., and a revised diagnoses is provided for the genus Euryte Philippi, 1843. Obtained cladograms also show that Ancheuryte Herbst, 1989 is nested deeply within the Euryte clade, so the genus is synonymized and its only species is transferred, as E. notabilis (Herbst, 1989) comb. nov. A key to species of Euryteinae is also provided.
