Review of the Palaearctic Acomopterella Zaitzev (Diptera,Sciaroidea, Mycetophilidae)

The distribution of Acomopterella species in the Palaearctic region has been re-examined in this study, using recently collected material. The European species was found to be distributed in the eastern Palaearctic as well. A second Palaearctic species from Honshu (Japan) is herein described. The morphology of adult specimens was studied by light microscopy and scanning electron microscopy. The shape of functional specialized setae on mid tibiae in Acomopterella and seven further fungus gnat genera is described and the suitability of this character for systematic studies is discussed. Details of a “hind tibial organ” are described.The position of Acomopterella in the tribe Gnoristini is briefly discussed. Acomopterella is found to be more closely related to Speolepta Edwards, 1925, than to any other recent genus.     

中国心菌蚊属研究(双翅目:菌蚊科)

心菌蚊属Ｃｏｒｄｙｌａ Ｍｅｉｇｅｎ生活于肉质真菌Ｒｕｓｓｕｌａ属及地下真菌Ｒｈｉｚｏｐｏｇｏｎ属,主要取食菌柄基部,形成小而致密的白丝茧,在地下化蛹。仅分布于全北区,已知欧洲２０种,新北区１０种。本文报道中国心菌蚊属１新种和１新纪录种,模式标本保存于浙江林学院昆虫标本室。本属为中国新纪录属。北方心菌蚊,新种Ｃｏｒｄｙｌａ ｂｏｒｅａｌｉｓａ Ｗｕ,ｓｐ．ｎｏｖ．（图１～３）雄翅长２．９～３．６ｍ     

中国菌蚊科属的系统发育关系分析(双翅目:眼菌蚊总科)

采用Hennig 86程序,以柄菌蚊科和喙菌蚊科代表种为外群,选取48个特征,使用mhen-nig^*和bb^*指令在586微机上运算,首次对菌蚊科中5亚科28属的28种进行支序分析,探讨各分类单元系统发育关系。结果表明：菌蚊亚科与滑菌蚊亚科的亲缘关系较近,二者互为姐妹群,粘菌蚊亚科属于原始类群;菌蚊亚科为5个亚科中的进化类群;邻菌蚊亚科可能为并系群;真菌蚊亚科是介于邻菌蚊亚科与菌蚊亚科之间的类群。
