The Tetrabothrus fauna of China

Including the newly described species, Tetrabothrus is now represented in China by six named species, four of which have been recorded from Yunnan, two from Shaanxi (one of them from the border region between Shaanxi, Hubei, and Chongqing), and one from northern Sichuan ( Map 1 ). Four species are currently known only from their respective type localities. All the specimens were sifted from leaf litter in various, usually moist forest habitats at altitudes of 1700-2510 m. The total number of Tetrabothrus specimens known from China amounts to twelve (one of them unnamed). As a rule, only a single specimen was collected per locality; only on two occasions were two specimens collected in the same locality.

The genus now includes a total of 28 named species, 18 of which have been recorded from the southern East Palaearctic region.
