A new species of the genus Bulbistridulous from Hubei Province is described with demonstration of the Karyotype.The type speciemen is deposited in the Institute of Zoology,Shaanxi Teachers University. Bulbistridulous dentatus, sp.nov. (Figs. 1～3) This new species is similar to B. furcatus Xia et Liu and B. simplicis Xia et Liu,but differs from former in:♂ cerci not bearing branches; and differs from latter in: 1) end of cerci spiniform with inner denticle; 2) subgenital plate with deeper middle gap,the length nearly equal half total length of subgenital plate. Female: unknown. Body length:♂ 20.0mm; pronotal length:♂ 5.0mm; elytra length:♂ 29.0mm;hind femoral length:♂ 22.0mm. Holotype♂,Shennongjia,Hubei, 3-Ⅷ-1995.Collected by You Ping. The complements of this species consist of (2n=32A+XY) five pairs of metacentric and eleven pairs of telocentric autosomes,and a pair of subtelocentric largest sex chromosomes.(Figs.4,5)
