Abstract

Two new species of Thraulodes Ulmer, 1920 are described from Rio de Janeiro and São Paulo, Southeastern Brazil, based on male and female imagos. Thraulodes luisae sp. nov. differs from all other species of the genus by the short and wide penes spines, turning up to apex; triangular shape of styliger plate with median projection abrupt and short with rounded apex; abdominal and legs color pattern; and presence of 2-3 weakly marked cross veins basal to bullae. Thraulodes pinga sp. nov. differs from all other species of the genus by the wide shape of styliger plate with median projection short with wide base and truncated apex; abdominal and legs color pattern; and presence of 1 weakly marked cross vein basal to bullae.

摘要

基于雄性和雌性成虫，描述了采自巴西东南部里约热内卢和圣保罗的摇蚊科（Thraulodes Ulmer，1920）两个新物种。新物种路易莎摇蚊（Thraulodes luisae sp. nov.）与该属所有其他物种的区别在于：阳茎刺短而宽，向顶端上翘；抱握器板呈三角形，中部突起短而突然，顶端圆形；腹部和腿部的颜色模式；以及在气泡基部有2 - 3条微弱的横脉。新物种平加摇蚊（Thraulodes pinga sp. nov.）与该属所有其他物种的区别在于：抱握器板形状宽，中部突起短，基部宽且顶端截形；腹部和腿部的颜色模式；以及在气泡基部有1条微弱的横脉。
