The species of Symplocodes Hebard (Blattodea: Ectobiidae: Blattellinae) with description of a new species from China

This paper provides a generic diagnosis, a species list and taxonomy for the genus Symplocodes Hebard, 1929. The new species Symplocodes euryloba sp. nov. from China is described and illustrated. Symplocodes tsaii Bey-Bienko, 1958 is regarded as a subspecies of Symplocodes marmorata (Brunner von Wattenwyl, 1893), i.e. S. marmorata tsaii comb. nov., and its differences from S. marmorata marmorata (Brunner von Wattenwyl, 1893) are discussed. Two known species, Symplocodes ridleyi (Shelford, 1912) and Symplocodes manubria Feng et Guo, 1990, are redescribed and illustrated, whereas one new specific synonym, i.e. Symplocodes brachialis, is proposed. A key to species worldwide is provided. The tarsal claws of these four species as well as one species of Chorisoserrata Roth, 1998 are examined and photographed to compare the intergeneric differentiation of claw specialization and to discuss its function.     

A new genus and new species (Orthoptera: Acrididae: Gomphocerinae) from south-east Xizang,China

In 2007, a 3-year survey was started in northeastern Italy to assess the influence of agricultural management on parasitoid composition and parasitism rates of parasitoids attacking larvae and pupae of Syrphidae (Diptera). Two types of management were considered – intensive (including wheat and maize monoculture with very low or null vegetation diversity) and extensive (with different types of habitats, characterized by a higher vegetation complexity). In habitats simplified by intensive agriculture, and particularly in maize fields, parasitism rates of syrphid larvae were higher than recorded in more diversified habitats. A substantial difference in the composition of the parasitoid complex was also found. In extensive and wheat sites, Diplazontinae (Braconidae), highly specialized to Syrphidae, were the dominant parasitoids, whereas in maize fields Pachyneuron (Pteromalidae) species, known as generalists, accounted for more than 80% of total parasitoids. In the habitats where Pachyneuron spp. were dominant, parasitism rates were very high. Conversely, in habitats where Diplazontinae were more abundant, the parasitism rates were very low. The higher rate of parasitism of syrphid larvae and pupae recorded in intensive monocultures could have a large impact on the development and control of aphid populations in such crops.     

Disjunct distribution of Szeptyckiella gen. nov. from New Caledonia and South China undermines the monophyly of Willowsiini (Collembola: Entomobryidae)

Morphology of scales is an important taxonomical character at all levels of Entomobryidae taxonomy. A new scaled genus of Collembola, Szeptyckiella gen. nov., and three new species are described: Szeptyckiella boulouparica sp. nov. and Szeptyckiella sinelloides sp. nov. from New Caledonia, and Szeptyckiella lii sp. nov. from South China. The genus, assigned to Willowsiini, is characterized by pointed scales on the body, eyes and pigment absent, antennal apical bulb absent, dens lacking spines and scales, and bidentate mucro with a short basal spine. It is closest to Hawinella from Hawaii but the latter possesses a falcate mucro. However, its morphological characteristics and its disjunct distribution raise a number of problems. Its widely disjunct distribution is difficult to explain in terms of palaeobiogeographical or more recent dispersal events. The new genus is similar to Sinella without consideration of scales, although both genera are placed in different tribes following the current supra-generic classification of Entomobryidae. We discuss other cases of paired genera differing only by the presence or absence of scales, and placed in either Willowsiini or Entomobryini. On this basis, we assume that scale presence could independently occur in the former tribe, questioning the monophyly of the tribe Willowsiini.     

Shamshevia,a new genus of long-legged flies from Namibia (Diptera: Dolichopodidae: Diaphorinae)

The genus Shamshevia Grichanov, gen. nov. is described from Namibia to accommodate a new species, Shamshevia hoanibensis Grichanov sp. nov. Despite flattened posterior mesonotum, the new genus is placed in the subfamily Diaphorinae and is considered close to the genus Dactylonotus Parent, differing from the latter in peculiar characters of male antenna, wing and genitalia.     

A new genus and species of Haplozetidae (Arachnida: Acari) from Great Britain with a key to the European genera

A new genus of mite, Pseudoprotoribates of the family Haplozetidae (Oribatida), is described and its systematic position discussed. The type species P. luxtoni was found in Great Britain, new to science and described herein. A key to the European genera of Haplozetidae is provided.     

A new genus Globulidrilus and three new enchytraeid species (Oligochaeta: Enchytraeidae) from Seoraksan National Park (Korea)

From the Seoraksan National Park, Korea, a new enchytraeid genus, Globulidrilus gen. nov., is defined and three new species, Globulidrilus helgei sp. nov., Fridericia seoraksani sp. nov. and Mesenchytraeus longiductus sp. nov., are described. Globulidrilus also includes Marionina riparia Bretscher, 1899 Bretscher, K. 1899. Beitrag zur Kenntnis der Oligochaeten-Fauna der schweiz. Rev Suisse Zool., 3: 369–426.  [Google Scholar] augm. ?ernosvitov 1928, a globally distributed species with a complicated taxonomic history. Pending a revision of Marionina riparia sensu latu (auct.), we retain the species name riparia for a variant of common occurrence in Europe.

A new genus and two new species of Argeiinae (Crustacea: Isopoda: Bopyridae) from the Indo-west Pacific

Three hosts from Indo-west Pacific including Kiribati, Guam Island and Australia were examined, and found to be infested by three species of the subfamily Argeiinae. We describe Paraeragia kiribatiensis gen. nov., sp. nov. from Kiribati infesting Synalpheus gracilirostris. The new genus is most related to Eragia and it can be distinguished by female with triangular pleon, lateral plates extend posteriorly, paired uropods, widely opened brood pouch. Argeiopsis guamensis sp. nov. from Guam Island infesting Synalpheus cf. stimpsoni. The new species is most similar to Argeiopsis inhacae but differs in female with curved posterior margin of first oostegite, partly fused pleomeres, and male with head separated from first pereomere, pleon as wide as seventh pereomere. We also record Stegoalpheon kempi from Australia for the first time, infesting Alpheus cf. perplexus. Keys to the nine genera of Argeiinae, and to three species of Argeiopsis are provided. A table for all 13 species of Argeiinae with localities and host records is also provided. A table comparing the distribution of lateral plates and morphology of pleopods and uropods among argeiine genera is presented.

Three new species of earthworms belonging to the genera Amynthas and Metaphire (Oligochaeta: Megascolecidae) from Yunnan,China

ABSTRACT

Herein, three new species are described, all from Yunnan Province, China: Amynthas hiatus sp. nov., Amynthas recavus sp. nov. and Metaphire daliensis sp. nov. Amynthas hiatus sp. nov. belongs to the Amynthas aeruginosus-group, A. recavus sp. nov. belongs to the Amynthas corticis-group and M. daliensis sp. nov. belongs to Metaphire insulana-group. Amynthas hiatus sp. nov. and M. daliensis sp. nov. have two pairs of spermathecal pores in 7/8-8/9, A. recavus sp. nov. has four pairs of spermathecal pores in 5/6-8/9. The male pores of A. hiatus sp. nov. are 1/3 circumference apart ventrally and each on top of a large, raised pulvinate pad; the male pores of A. recavus sp. nov. are 2/5 circumference apart ventrally and each on top of a raised, elliptic, collapse-topped porophore; the male pores of M. daliensis sp. nov. are 2/5 circumference apart ventrally and in the oval copulatory chambers. In this paper, the anatomical and morphological characters of these three species are described. We also sequenced COI and 12S gene fragments in order to provide an analysis of K2P distances and a neighbour-joining tree.     

Description of two new species and a new genus of bopyrid isopod parasites (Bopyridae: Pseudioninae) of hermit crabs from China

This is the first record from China of the bopyrid isopod genus Asymmetrione, of which the new species Asymmetrione globifera, a parasite of the hermit crab Dardanus hessii (Miers) in Beibu Gulf and South China Sea, is described. The female A. globifera differs from Asymmetrione nossibensis Bourdon in the shape of its barbula and ornamentation of the first oostegite. A tabulation of the occurrence of all currently known species of Asymmetrione is included. New genus Parasymmetrione is described. The type species, Parasymmetrione tuberculineata, sp. nov., a parasite of Clibanarius corallinus (H. Milne-Edwards) Xisha, is similar in appearance to Asymmetrione spp. but differs, in the female, in not having the propodi of its pereopods produced into sockets and having uniramous uropoda; the male of P. tuberculineata sp. nov. differs from species of Asymmetrione in having the dactyli of only its first pair of pereopods markedly longer than those of the following pereopods.

A new genus and species of Caprellidae (Crustacea: Amphipoda) from Kiribati

ABSTRACT

Luisacaprella eliae gen. nov, sp. nov. (Crustacea, Amphipoda, Caprellidae) is described bwct ased on specimens collected from Kiribati, Pacific Ocean. The new genus is close to Aciconula but can be mainly distinguished by the following characteristics: (1) pereonites 6 and 7 are fused in Luisacaprella gen. nov. while they are separated in Aciconula; (2) the setal formula of mandibular palp is 2-x-1 in Luisacaprella and 1-x-1 in Aciconula; (3) pereopods 3 and 4 are two-articulate in males and females of Luisacaprella, whereas there is sexual dimorphism in Aciconula, and males have pereopods 3 and 4 two-articulate while females have pereopod 3 two- or three-articulate and pereopod 4 four-articulate. The new species L. eliae is additionally characterised by its tiny size (<3 mm). The new taxon was collected from dead branching coral of shallow waters (3–32 m). Further studies targeting small caprellids which could easily be overlooked from substrates such as sediments and dead corals are needed to properly understand the global caprellid diversity of tropical and temperate areas.

Two new genera of the family Pilumnidae (Crustacea: Decapoda: Brachyura) from Queensland,Australia

Two new genera of Pilumnidae each with a single new species are described from southeastern Queensland waters. Priapipilumnus is defined by the greatly swollen base and simple blunt apex of the male first pleopod and the concomitant posteriorly protruding, bilobed, third abdominal segment. Takedana is separable by the very short spinous anterolateral margins, the swollen branchial regions, the moderately short walking legs, and the strongly spined chelae. Actumnus pugilator is reassigned to Bathypilumnus Ng and Tan, 1984.     

New genera and species of the Synchelidium group (Amphipoda: Oedicerotidae) from Asia-North Pacific

Four new species and two new genera belonging to the family Oedicerotidae are reported from Korea and Vietnam. Two new genera, Orthomanus and Imbachoculodes are described, with three new species, namely Orthomanus koreanus gen. et sp. nov., Imbachoculodes namhaensis gen. et sp. nov. and Imbachoculodes vietnamensis gen. et sp. nov. The monotypic genus Orthomanus is characterized by the very short carpi and transverse palms of gnathopods 1 and 2, the reduced dactyli on pereopods 3–6, and the greatly enlarged distolateral spine-tooth on the outer plate of maxilla 1. Imbachoculodes has slender gnathopods 1 and 2 with elongated carpi, pereopods 3 and 4 with elongated dactyli, and a narrow basis of pereopod 7. The fourth new species, Sinoediceros hwanghaensis sp. nov. has a greatly reduced flagellum on antenna 2, a broadened meri on pereopods 3 and 4, and an elongated maxilliped outer plate. Keys are provided to 1) the North Pacific genera of the Synchelidium group, 2) species of Imbachoculodes, and 3) species of Sinoediceros.
