title: Onychiurid species from Wanda Mountains in China, with descriptions of two new species (Collembola, Onychiuridae).
abstract: A checklist of onychiurid species from the Wanda Mountains in China is presented. Eighteen species belonging to twelve genera have been found, including two new species. Bionychiurus qinglongensis sp. n. can be easily distinguished from other known species of the genus by the absence of pseudocelli on Th. I tergum and fewer number of vesicles in postantennal organ. Onychiurus heilongjiangensis sp. n. is diagnosed by pseudocellar formulae as 32/133/33352 dorsally and 3/011/31120 ventrally, parapseudocellar formula as 0/000/111001+1(m), ratio of anal spine/unguis as 0.6, unguiculus without inner basal lamella, and male ventral organ absent.
