中国弯翅蠊属(蜚蠊目:弯翅蠊科)研究

A STUDY ON THE GENUS PANESTHIA FROM CHINA (BLATTARIA: PANESTHIIDAE)

弯翅蠊属(Panesthia Serville,1831)是弯翅蠊科(Panesthiidae)中最大的类群。其种类生活于树林的枯枝朽木、地面落叶、垃圾、石缝及各种堆积物中,以各种腐殖质、树皮下的木质为生。过去,Brunner De Wattenwyl, C., Saussure, H., Hanitsch, R.以及Bey-Bienko,G.等曾零星报道过中国弯翅蠊10种,除2种异名,实为8种。近几年,我们结合野外采集,鉴定各地林虫标本,整理了我国弯翅蠊属,鉴定出8种,其中3种为中国的已知种,3种为中国新纪录,2个新种。本文长度单位均为mm。
