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.

摘要

新物种紫金李氏长角跳虫（Leeonychiurus zijinensis sp. nov.）在中国东部被描述。它与抚松李氏长角跳虫（L. fusongensis Sun & Arbea, 2014）以及麦氏李氏长角跳虫（L. mai (Wray, 1950) sensu Bernard (2015)）相似，具有相同的背侧伪眼公式（32/133/33343）。然而，新物种可通过以下特征区分：腹部腹板II - IV的伪眼公式为111（抚松李氏长角跳虫为112，麦氏李氏长角跳虫为001）；腹部背板V上存在不成对的轴刚毛m0（抚松李氏长角跳虫和麦氏李氏长角跳虫中不存在）；触角后器的泡囊更多（新物种中有18 - 20个，抚松李氏长角跳虫中有13 - 16个，麦氏李氏长角跳虫中有15个）。提供了李氏长角跳虫属已知世界物种的检索表以及中国长角跳虫科物种名录。
