摘 要:记述了飞虱科1新属和1新种:西藏宽唇飞虱Laticlypenus tibetensis gen. et sp.nov.。该属根据后足胫距和雄虫阳茎构造特征,应归属于飞虱亚科中的凹距飞虱族,其亲缘关系接近于圆翅飞虱属Yuanchia Chen et Tasi和奇节飞虱属Mirocauda Chen,但可根据下列的特征与后两者相区别:1) 后唇基基部膨大,向两侧扩张,明显宽于额的端部(后者为常态,仅稍宽于额的端部),侧面观,前唇基基部明显低于后唇基的端部,呈阶梯型(后者在同一线上);2)后足刺式为5-8-4(后者为5-6-4);3)后翅ⅡA1脉在端部分岔,A脉分为4支伸达后缘(后者ⅡA1脉在端部不分岔,A脉分为3支伸达后缘)。模式种为西藏宽唇飞虱Laticlypenus tibetensis sp.nov.。标本采自西藏墨脱上亚东村,灯光诱集。新种模式标本保存在南京农业大学昆虫标本室。A new genus and species of Tropidocephalini is described and photographed. In the aedeagus with phallobase and phallobasal process, and the shape of the head including vertex ,frons, clypeus and antennae) , the genus Laticlypenus gen. nov . is releted to Yuanchia Chen et Tasi and Mirocauda Chen,but can be distinguished from both the genera by the spinal formula of hind leg 5-8-4 (5-6-4 in the latter) ; the w ings w ith ⅡA1 vein forked at near apex (not forked in the latter) ,especially by the uniquely shaped clypeus, in w hich the postclypeus at base strongly expanded laterad,in lateral view ,anteclypeus distinctly lower than postclypeus,steps-shaped (at the same line in the latter) . Type species: Laticlypenus tibetensis sp. nov . collected at light in M etok,Tibet, China (29. 33°N ,95. 34°E; alt. 1 040 m) .
