Abstract

Chironomidae is a diverse Diptera family found worldwide. The genus Diplosmittia Sther, 1981, currently with 11 valid species, has been found exclusively in the New World, mainly in the Caribbean and in the northern parts of South America; only three species are recorded from Brazil and none from Colombia so far. In the present study a new species of Diplosmittia is described and illustrated based on material collected in northeastern Brazil. It appears to be most closely related to Diplosmittia beluina Andersen, 1996, but can be distinguished by morphological differences in the virga and gonostylus. Diplosmittia harrisoni Sther, 1981 is documented for the first time from Colombia, and D. carinata Sther, 1985 is formally placed as a junior synonym of D. harrisoni. In addition, an update identification key to all known species of the genus has been provide.

摘要

摇蚊科是一个分布于全球的多样化双翅目昆虫家族。1981年建立的双脉摇蚊属（Diplosmittia Sther）目前有11个有效物种，仅在新大陆被发现，主要分布在加勒比地区和南美洲北部；到目前为止，巴西仅记录有3个物种，哥伦比亚尚无记录。在本研究中，基于在巴西东北部采集的材料，描述并图示了双脉摇蚊属的一个新物种。它似乎与1996年的贝氏双脉摇蚊（Diplosmittia beluina Andersen）关系最为密切，但可通过阳茎和生殖突的形态差异加以区分。1981年的哈氏双脉摇蚊（Diplosmittia harrisoni Sther）首次在哥伦比亚被记录，1985年的脊状双脉摇蚊（D. carinata Sther）被正式定为哈氏双脉摇蚊的次异名。此外，还提供了该属所有已知物种的最新鉴定检索表。
