查看更多>>摘要：The egg and five instars of Trepobates are described based on examined material of T. taylori and published information of T. inermis, T. knighti, T. panamensis, T. pictus, T. subnitidus and T. trepidus. The characters most useful in identifying nymphs I-V of Trepobates are: the width of the head; the lengths of the antennae, femora 1-3, tibiae 2-3 and tarsus 2-3; the Y-shaped ecdysial line of the head; the colour patterns of the pro- and mesonotum; and the urosternites VIII and IX. A key to the fivenymphal instars of Trepobates is provided. The five instars of T. taylori are described and illustrated for the first time, with emphasis on the morphometry and colour pattern of selected structures, and chaetotaxy of the antennae; the egg is figured and redescribed. The characters useful in identifying nymphs I-V of this species are: the colour pattern of the head; the chaetotaxy of the antennal segment I; the lengths of the antennal segment III and mesonotum; and the width of the pronotiim. Differences between sexes in nymphs IV and V are presented.
查看更多>>摘要：The genera Perinaenia and Isoura are revised, and four new species, P. mingchyrica sp. n. (Taiwan), P. atripunctum sp. n. (China, Shaanxi), P. nigrifascia sp. n. (Vietnam) and, clara sp. n. (Nepal, Vietnam and Indonesia) are described. The systematicrelationships of the genera Perinaenia, Isoura and Exophyla are discussed on the basis of their external and genitalic features.

Gymnogryllus (Gryllidae: Gryllinae) was established by Henri deSaussure in 1877, with Gryllus elegans Guerin-Meneville as the type species. It belongs to the tribe Gryllini and is easily separated from other members by the following characters: face distinctly longer than width; oblique veins of male tegmen nearly straight or slightly S-shaped; ectoparamere with widened distal part of large upper medial process and large proximal endoparameral apodeme; ovipositor short and armed with small hook before apical part of lower valvae (Gorochov 2001). This genus is knownto occur in the localities from India to Australia and most species of the genus are distributed in tropical areas of southern Asia, including the Indian subcontinent, west Himalaya, Burma, Vietnam and Malaysia (Gorochov 2001; Eades & Otte 2010). 34 species are currently reported worldwide (Chopard 1936; Chopard 1969; Otte & Alexander 1983; Otte et al. 1988; Liu et ah 1995; Desutter-Grandcolas 1996; Ichikawa 1996; Gorochov 1983, 1996, 1998, 1999, 2001; Xie & Zheng 2003; Eades & Otte 2010).

Two new speciesof Gryllotalpa from Henan and Zhejiang, China are also described. Gryllotalpa is the largest genus among the five genera in the mole cricket subfamily Gryllotalpinae. It is distinguished from other genera by the following characters: fore tibiae with four dactyls; tympana covered and opening in the form of a slit; basal spur of fore leg arising from femur; veins in lateral field of fore wings pointing toward wing-tips.

The second known species in the genus Parastethynium, P. hirsutum Huber sp. n.,from Indonesia (Sulawesi) is also described. The latter represents the first record from the Oriental region. The basic biology of P. maxwelli is presented. Mean progeny produced per female was 57 with a female proportion of 0.59. Mean egg to adult development time was 11 days, at 24.5°C-29.7°C and 72-93% relative humidity. Survival time of females and males fed on honey and water was longer compared to males and differed significantly with those provided with water only or nothing at all.
查看更多>>摘要：Heterotrissocladius Sparck from China, including 5 species is reviewed. Three new species, H.flectus sp. n., H. quartus sp. n. and H. reductus sp. n. are described and illustrated as adult males, and H. scutellatus Goetghebuer is recorded from China for the first time. A key to the males of the reviewed species is presented. Heterotrissocladius was erected by Sparck in 1922. Saether (1975) revised the genus from the Nearctic and Palae-arctic regions. To date, Heterotrisshcladius comprises 19 speciesrecorded worldwide: 9 species in the Palaearctic region, 7 in the Nearctic region and 6 in the Oriental region (Ashe and Cranston 1990, Oliver et al. 1990, Saether 1975, S^ther 1993, Ssther & Schnell 1988, Singh 1958, Star and Wiedenbrug 2005, Sublette and Sublette 1973, Yamamoto 2004).
