In the present, a subgenus and a new species of the genus Cyrtopsis Bey-Bienko, 1962 from China are described, and a key to the subgenera and species is given. The type specimens are deposited in Shanghai Entomology Museum, Chinese Academy of Sciences.
Cyrtopsis (Cyrtopsis) robusta, sp. nov. (Figs.7~11)
Male: Body of strong build. Tegmina extending to the middle of second abdominal tergit. Fore tibiae with 4 inner and 4 outer spines and a pair small apical spurs on ventral surface, middle tibiae with 3 inner and 5 outer spines and a pair small,apical spurs; hind tibiae with 26-28 spines on each side above and 3 pairs apical spurs. Tenth abdominal tergite, cerci and subgenital plate as in figs, 8-9, dorsal lobe of genitalia with projecting lateral angle and with a curved median lobe (Fig. 10).
Female unknown.
Coloration yellowish, with a red brown band on dorsal surface, bearing blackish longitudinal stripes at side of band (Fig. 7), hind keen and tibial spines darkish.
Length of body 14.0-15.0 mm; pronotum 7.0 mm; tegmina 2.0 mm; hind femora 13.5-14.5 mm.
Holotype: ♂, Neicujiang, Longsheng County, Guangxi Zhuangzu Autonomous Region, 1979-Ⅶ-26; Paratype: 1 ♂, Neicujiang, Longsheng County, Guangxi Zhuangzu Autonomous Region, 1963-Ⅵ-07, CHANG Lu-Lin.
This new species is similar to Cyrtopsis (Cyrtopsis) scutigera Bey-Bienko, 1962. But differs from the latter in the body noticeably larger sized, longer process of tenth abdominal tergite of male and shape of cerci and genitalia.
Neocyrtopsis subgen, nov.
Type- species: Cyrtopsis variabilis Hsia et Liu, 1993.
Description. Pronotum of male very large, almost occupied half of body, with metazoan considerably elevated and expanded, with low lateral plate and oblique hind margin, without humeral sinus. Tegmina concealed under the pronotum, with stridulatory fields in male. Fore coxae with a spine, all femora unarmed, lower lobe of hind knee spined, tibial auditory structure open on both sides, fore and mid tibiae with movable spines on lower margin, hind tibiae with 3 pairs apical spurs. Tenth abdominal tergite of male produced into two labes, epiproct well developed, subgenital plate with styles; genitalia with sclerotized dorsal lobe.
Included species: type species only.
Comparison. This new subgenus is very similar to Cyrtopsis (Cyrtopsis) Bey-Bienko 1962, It differs from the latter in the tenth abdominal tergtte of male hardly modified and epiproct well developed, Bey-Bienko (1962) supposed that this genus is related to the Mediterranean genus Cyrtaspis Fischer. Gorochov (1998) recognized that this genus is related to the oriental genus Xiphidonema Ingrisch.
