摘    要:炭色厕蝇种团Fannia carbonaria group是厕蝇属Fannia中的12个种团之一。该种团全世界已知20种,主要分布于全北界。报道了产自中国的该种团8个种的名录及分布,编制了该种团分种检索表,对其中2个新种F.antilocera sp.nov.,F.tauricornis sp.nov.和1个国内新记录种F.imperatoria Nishina,2002分别予以记述。新种F.antilocerasp.nov.同小须厕蝇F.minutipalpis(Stein,1895)相近缘,但后触角第三节长为宽的3倍,盾片具灰色粉被,后足股节后腹鬃列分布到基部2/3处,尾器明显不同等可予以区别。新种F.tauricornis sp.nov.同羊角厕蝇F.capricornis Xue,1996相近缘,但新种触角第三节长为宽的3倍,前缘基鳞黄色,足暗棕色;第一腹板具毛,侧尾叶后缘中部无角形突出,杆状突分为两个短突等即可区别;另与本亚种团的F.trigonfera Chillcott,1961,F.japonica japonica Nishida,1974,F.japonica amamiensis Nishida,1975亦相近,但新种肛尾叶外侧突横臂较长,侧尾叶后缘中部无角形突出,杆状突分为2个短突等亦可区别。新种模式标本和其它研究标本均保存于沈阳师范大学昆虫研究所昆虫标本室。

Abstract:The present paper deals with the Fannia carbonaria species group (Diptera: Fannidae) in China. Eight species are recorded, 2 of them are described as new to science, i.e. F. antilocera sp. nov. and F. tauricornis sp. nov., and F. imperatoria Nishina 2002 is recorded for the first time in China. Fannia antilocera sp. nov. is most closely related to F. minutipalpis (Stein, 1895), but can be identified by the third antennal segment 2.5 times as long as broad, scutum with brownish-grey, hind femur with a row of pv setae only at basal half. F. tauricornis sp. nov. is very close to F. capricornis Xue, 1996, but is separated on the third antennal segment 3 times as long as wide, basicosta yellow, legs dark brown, the first sternite with hairs, surstylus without expansion on median dorsal; bacilliform process with 2 short processes. In addition, F. tauricornis sp. nov. is fairly related to F. trigonfera Chillcott, 1961, F. japonica japonica Nishida, 1974, F. japonica amamiensis Nishida, 1975, but sets apart by several distinctive characters: cereal plate with longer arm of outside projection, surstylus without expansion on median dorsal, and bacilliform process with 2 short processes. The paper also reports the characters of the F. carbonaria species group. The group as a whole can be recognized by the hind femur without rows of pv setae at apex, the mid tibia with 2 ad and 2 pd setae and the single strong prealar seta.
Keywords:Diptera  Fanniidae  Fannia carbonaria species group  new species  China
