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.

Karkata,a new genus of gecarcinucid freshwater crab with two new species,and four new species of Pilarta Bahir and Yeo, 2007 and Cylindrotelphusa Alcock, 1909 (Decapoda: Brachyura) from Kerala,India

A new genus of freshwater crab, Karkata gen. nov., with two species, K. ghanarakta sp. nov. (type species) and K. kusumbha sp. nov., and two new species each of Pilarta Bahir and Yeo, 2007 (P. aroma sp. nov. and P. punctatissima sp. nov.) and Cylindrotelphusa Alcock, 1909 (C. breviphallus sp. nov. and C. longiphallus sp. nov.), are described from Kerala, India. Additionally, C. granulata (Pillai, 1951) comb. et stat. nov. is recognised as a distinct species. Karkata gen. nov. is distinguished from other Indian gecarcinucid genera by a suite of carapace and gonopod characters, including a moderately arched, smooth carapace, the presence of a prominent suture between male thoracic sternites 2, 3 and 3, 4, the absence of a flagellum on the third maxilliped exopod, a very short terminal segment of the male first gonopod (G1), and a short distal segment of the male second gonopod (G2). Karkata ghanarakta sp. nov. is differentiated from K. kusumbha sp. nov. by the shape of the G1 subterminal segment and its live colouration. Pilarta punctatissima sp. nov. is distinct among the congeners mainly by its densely punctate carapace, densely setose anterolateral and posterolateral margins of the carapace, stouter G1 terminal segment, and relatively long G2 distal segment whereas P. aroma sp. nov. can be separated from P. anuka Bahir and Yeo, 2007 by its relatively smooth carapace, deep H-shaped groove, relatively long G1 terminal segment, and almost straight outer margins of the G1 terminal and subterminal segments. Cylindrotelphusa breviphallus sp. nov. is differentiated from C. longiphallus sp. nov. and C. steniops (Alcock, 1909) by its stout G1, with a stout, short terminal segment. Cylindrotelphusa longiphallus sp. nov. is distinguished from the congeners by its shallow, narrow cervical grooves and relatively slender ambulatory legs. An identification key to the species of Karkata, Pilarta and Cylindrotelphusa is 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.
