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.     

Taxonomy of the genus Tantunema Siddiqi, 1982 (Dorylaimida: Tylencholaimidae) with description of one new and two known species

A review of the genus Xistra Bolivar 1887 (Orthoptera: Tetrigidae) with description of two new species

Two new species, Onychiurus gulinensis sp. nov. and Onychiurus antennalis sp. nov., are described from Eastern China. The two new species share most features with Onychiurus, but possess 11 chaetae in the distal whorl of tibiotarsus (seven or nine in Onychiurus), granulated sense clubs on Ant. III organ (smooth in Onychiurus) and three manubrial rows of chaetae present (two in Onychiurus). Here we place the two new species in Onychiurus rather than erect a new genus and the three characters considered to be unstable in many genera are discussed.

Notes on the Amazonian genus Hyogonia China (Hemiptera: Cicadellidae: Proconiini) with a description of a new species

Oncometopia batesi Distant, described from northern Brazil (State unknown), is transferred to the genus Hyogonia China. Hyogonia brasiliana sp. nov. is described from Northern Brazil, Pará State, the easternmost record of the genus. The new species is easily distinguished from all other Hyogonia species by the following combination of characters: (1) pronotum without distinct transverse contrasting band; (2) pygofer with short processes that do not attain its apex; (3) both pairs of aedeagal atrial processes divergent and short, never longer than aedeagal shaft; and (4) aedeagal caudal pair of atrial processes with bases close to each other, appearing as a single bifurcated robust process. Hyogonia batesi and H. brasiliana, together with an unidentified female from Acre State, represent the first authentic records of the genus Hyogonia from Brazil. Previous records of H. reticulata (Melichar) and H. youngi Emmrich and Lauterer from Brazil are erroneous as their recorded locality ‘Cumbase’ is most probably located in Peru (San Martín Department). Other new records from countries and major federal divisions are noted as follows: the genus Hyogonia (unidentified species) from Barinas State (Venezuela); H. batesi from Ecuador (Orellana Province); H. reticulata from Amazonas and Junín Departments (Peru); and H. youngi from Ecuador (Napo Province). A key to the known species of Hyogonia is provided.     

The African grasshopper genus Acanthacris (Orthoptera: Acrididae: Cyrtacanthacridinae)

The genus Acanthacris Uvarov is revised and four species are recognized: A. aithioptera sp. nov., A. deckeni (Gerstäcker), A. elgonensis Sjöstedt and A. ruficornis (Fabricius). Acanthacris elgonensis is raised to specific status for the first time. Acanthacris ruficornis is considered as two distinct geographical races: A. r. ruficornis and A. r. citrina (Serville). The following nominal taxa have been synonymized with A. r. ruficornis: A. ruficornis yemenita Uvarov, Gryllus locusta lineatus Stoll and Acridium ruficorne var. subimmaculata Finot. An identification key is provided for males, based largely on external morphological characters combined with those of the phallic complex. All the valid taxa are redescribed. Measurements, figures of genitalia and distribution maps are provided.

Review of the Japanese flatfishes of the genus Samariscus,with the description of a new species from Tonking Bay

Summary

The genus Samariscus of the right eye flounder has thirteen known species including the two described here. A key is given to all the species, and the Japanese forms are reviewed. Samariscus japonicus Kamohara and S. latus Matsubara and Takamuki live in somewhat deeper water, 100 to 200 metres. A certain isopod parasite is often found in the branchial cavity of the ocular side of S. japonicus. S. xenicus n. sp. from Kochi frequents a depth of about 20 metres in the littoral zone. Kamohara's S. huysmani is relegated to synonymy of this new species. Also a flatfish from Tonking Bay represents a new species described herein as S. asanoi.

A key to the species of Stelomon is included.     

Pentatrichosiphum (Sternorrhyncha: Aphididae), a generic account with the description of a new species from Hainan,China

The aphid genus Pentatrichosiphum Basu, 1969 Basu, A. N. 1969. Four new genera and nine new species of aphids (Homoptera) from West Bengal, India.. Oriental Insects, 3: 169–186. [Taylor & Francis Online] , [Google Scholar] is reviewed. Pentatrichosiphum longirostrum n. sp. from Lauraceae in Hainan, China is described. Pentatrichosiphum luteum Basu, 1969 Basu, A. N. 1969. Four new genera and nine new species of aphids (Homoptera) from West Bengal, India.. Oriental Insects, 3: 169–186. [Taylor & Francis Online] , [Google Scholar] is recorded for the first time from China, the first record of this genus. Some hitherto unknown morphs of P. luteum are described. The genus is redefined and keys to the four known species worldwide are also provided. The taxonomic status of Pentatrichosiphum is discussed based on morphological characters. Type specimens are deposited in the Zoological Museum, Institute of Zoology, Chinese Academy of Sciences, Beijing, China (ZMCAS).     

Considerations about the genus Pentoniscus Richardson, 1913 (Crustacea: Isopoda: Oniscidea) with description of a new species

The status of the neotropical genus Pentoniscus Richardson, 1913 is reconsidered and a diagnosis of this genus is given. It is shown that Pentoniscus Richardson, 1913 is a valid genus and not a synonym of Philoscia Latreille, 1804 as discussed by Schultz (1968). The type species, Pentoniscus pruinosus Richardson, 1913 is redescribed and for the first time figured in detail. A new species of Pentoniscus Richardson, 1913 is described from Costa Rica, Central America, which differs remarkably from its congeners in being unpigmented and blind.     

The genus Coralaxius redefined,with the description of two new species (Crustacea: Decapoda: Axiidae)

The genus Coralaxius is rediagnosed, and the type species C. nodulosus (Meinert, 1877), the holotype of which was found to be identical with C. abelei Kensley and Gore, 1982, is redescribed. The two new species of Coralaxius are described, viz. C. galapagensis from the Galapagos Islands, and C. indopacificus from Fiji and the Comoro Islands. On the basis of carapace, gill and appendage characters, it is concluded that C. indopacificus is more primitive than the other two species. The genus is thought to have had a tethyan distribution, with the eastern Pacific representative being cut off from the western Atlantic form with the raising of the Isthmus of Panama.
