绳蚋亚属(Gomphostilbia)的分组研究(双翅目:蚋科)

STUDIES OF SUBGENUS GOMPHOSTILBIA ON DIVIDE INTO GROUPS (DIPTERA:SIMULIIDAE)

Takaoka和Davies(1996),Crosskey和Howard(1997),把绳蚋亚属分成5个种组,作者在研究中国新疆绳蚋时,发现草地绳蚋S.(G.)meadowi An,Ma and Ma和阿勒泰绳蚋S.(G.)altayenseCai and An的跗突无或很短、细、顶端平齐或尖形,这些特征可作为新的组征,建议组成新组,即阿勒泰altayense组。我国现有绳蚋30种,分列4个组中,并附蚋种名录。

The Subgenus Gomphostilbia was first well defined by Crosskey （1967） and later by Datta （ 1973）, Takaoka （1983） and Davies ＆ Gyorkos （1987）. The most distinctive character of Subgenus Gornphostilbia is a combination of the haired katepisternum with the bare pleural membrane of both sexes of adults. This subgenus was divided into five-groups by Takaoka and Dvies （1996） and Crosskey and Howard （1997）. However, Simulium （Gomphostilbia） altayense Cai, An and Li, 2005 and Simulium （Gomphostilbia） meadowi An, Maha and Ma, 2003 from Xinjiang, China differ from the known Gomphostilbia species for having calcipala lacking or not developed, short, slender, tip level or point. On the basis of these different diagnostic characters within the Subgenus, the Xianjiang, China species of Gomphostilbia was divided into a new group （ altayense-group）, of which the main characteristics are as follows： pleural membrane bare, katepisternum covered densely long hairs, costa with spinules as well as hairs, basal portion of radius fully haired, hind basitarsus lacking calcipala or not developed with short, slender, level or point tip, pedisulcus develoved, the female claws with large basal tooth, spermatheca ellipsoidal, with longitudinal stripe pattern on surface.
