Abstract

A new collembolan species is described, Spinonychiurus sinensis sp. n., which has seven chaetae in the distal row of the tibiotarsi. It is placed in the genus Spinonychiurus due to two important characters: the two subsegments on Abd. III sternum and the absence of d0 on the head. This is the first report of the genus Spinonychiurus in China. The diagnosis of Spinonychiurus is broadened and the key to the world species is provided.

Keywords: Taxonomy; Thalassaphorurini; key; tibiotarsi.
