Abstract

The genus Tonkinosoma Jeekel, 1953 has hitherto been known to contain only two species, both from northern Vietnam. T. flexipes Jeekel, 1953, the type species of the genus, is recorded from Guangxi, southern China, for the first time. T. tianisp. n., a presumed troglobite, is described from caves in Guizhou, southwestern China. A key is presented to all three species of the genus.

Keywords: Guangxi; Guizhou; Tonkinosoma; key; new record; new species; troglobite.
