Abstract: In this paper, Prosopocoilus suprebus Bomans, 1971 (Coleoptera, Lucanidae) is newly recorded from China. The main diagnostic characters of this species are introduced. The external morphological differences between this species and its allied species, P. spineus Didier, 1927 and P. wuchaoi Huang & Chen, 2017, are compared in detail, and the colour plates of the three species are provided.

  • 锹甲科Lucanidae隶属于鞘翅目Coleoptera金龟总科Scarabaeoidea,全世界已描述100余属1800多种(含亚种),其中中国已记录26属近300种(含亚种)[14]。锯锹属Prosopocoilus Hope & Westwood, 1845因其成员之大颚形状呈锯齿状而得名[5]。本文报道采自云南西双版纳景洪市地区的锯锹属中国一新纪录种:四斑锯锹Prosopocoilus suprebus Bomans, 1971。本种前胸背板与鞘翅各分布一对对称的橘黄色斑块,据此特征命其中文名为四斑锯锹。
