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。

CLADISTICS ANALYSIS OF PHYLOGENETIC RELATIONSHIP AMONG GENERA IN FAMILY MYCETOPHILIDAE FROM CHINA(DIPTERA:SCIAROIDAE)

In this paper the phylogenetic relationship of family Mycetophilidae was studied at the genera level based on 48 morphological characters. The cladistic analysis was performed using the Hennig 86 program (Version 1.5). The in-group consisted of 28 known genera, Bolitophila and Lygistorrhina were used as the out-groups according to Matile (1996). A total of 48 characters were scored in the character state matrix. The result of cladistic analysis suggests that Mycetophilinae and Leiinae are sister groups; Sciophilinae is a primitive group in family Mycetophilidae, and Mycetophilinae is a derived group. The result also shows Gnoristinae is a paraphyletic group, and the subfamily Mycomyinae is intermediate between Mycetophilinae and Leiinae.
