Abstract

We describe apterous and alate viviparous females of a new species of the Lachninae genus Eulachnus (Eulachnini) from China. The new species, Eulachnus blackmani sp. nov., can be easily separated from other Asian representatives of this genus: the ultimate rostral segments are without accessory setae; the spinal scleroites are larger than the pleural and marginal ones; there are a few very long setae on the distal part of the tibiae and on the hind tarsus. The new species is morphologically most similar to the European E. nigricola (Paek), and hence unusual within the Asian Eulachnus fauna.

摘要

我们描述了来自中国的 Lachninae 属 Eulachnus（Eulachnini）新种无翅和有翅胎生雌虫。新种 Eulachnus blackmani sp. nov. 可以很容易与该属的其他亚洲代表区分开来：末端额段没有附属刚毛；脊状骨片比侧板和缘片大；胫节和后跗节的远端有几根非常长的刚毛。新种在形态上与欧洲的 E. nigricola（Paek）最为相似，因此在亚洲 Eulachnus 动物群中是不寻常的。
