Abstract

Parapsectrocladius setosus sp. n. is described and figured as pupa and male imago, based on material collected in Patagonia, Argentina. The male of the new species groups with P. escondido Cranston & Añón Suárez by having the anal point tapering triangular; inferior volsella simple, rounded, without any dorsal ridge and apically blunt. It can be distinguished from P. escondido by the possession of strong setae on the inner margin of inferior volsella. New material of Parapsectrocladius belonging from several localities allows us to emend the generic diagnosis of the adult male, female and larva of Parapsectrocladius, discuss its phylogenetic position and to expand the geographic distribution of P. acuminatus Cranston, P. escondido and P. reissi. Cranston.

摘要

基于在阿根廷巴塔哥尼亚收集的材料，描述并绘制了新物种毛拟摇蚊（Parapsectrocladius setosus sp. n.）的蛹和雄性成虫。新物种的雄性与隐匿拟摇蚊（P. escondido Cranston & Añón Suárez）归为一组，其肛尖呈渐细的三角形；下抱器简单、圆形，无任何背嵴且顶端钝圆。它与隐匿拟摇蚊的区别在于下抱器内缘有强壮的刚毛。来自几个地点的拟摇蚊新材料使我们能够修订拟摇蚊属成年雄性、雌性和幼虫的属诊断，讨论其系统发育位置，并扩大尖突拟摇蚊（P. acuminatus Cranston）、隐匿拟摇蚊和雷氏拟摇蚊（P. reissi Cranston）的地理分布。
