Abstract

The new species Leeonychiurus zijinensis sp. nov. is described from east China. It is similar to L. fusongensis Sun & Arbea, 2014 and L. mai (Wray, 1950) sensu Bernard (2015) as having the same dorsal pso formula (32/133/33343). However, the new species can be distinguished by pso formula on Abd. sterna II–IV as 111 (112 in L. fusongensis, and 001 in L. mai), presence of the unpaired axial chaetae m0 on Abd. tergum V (absent in L. fusongensis and L. mai), and more vesicles of postantennal organ (18–20 in the new species, 13–16 in L. fusongensis, and 15 in L. mai). A key to the world known species of the genus Leeonychiurus and a checklist of Chinese Onychiurini species are provided.
