整理鉴定武陵山生物资源考察所采果蝇科标本,发现果蝇亚属(Drosophila)一新种。现记述如下。模式标本保存于中国科学院昆明动物研究所。 棒果蝇 Drosophila(Drosophila) fustiformis新种(图1—3) :体长约3.5mm,翅长约3.0mm。 头部:复眼红色,被微毛。触角第二节黄色,具2根长刚毛;第三节亦黄色;触角芒分枝毛背侧5,腹侧2,端叉大。下颚须黄色,顶端及外侧亚中部具2根长刚毛。腹外侧散生几根小刚毛。单眼三角区及眶区黄色,额棕黄色,单眼内侧棕色。单眼鬃长,外伸,具几对小刚毛。额从侧面观银白色,具额毛。额为头宽的1/2。颜浅黄色,鼻瘤下部高。
The present paper describes a new species, Drosophila (Drosophila) fustiformis Zhang et Liang, which belongs to immigrans species-subgroup. It is allied to Drosophila (Drosophtla) mberrimoides Zhang et Gan, especially in having similar structure of gonopod (?). Aedea-gus distally trumpet-like resembled Drosophila (Drosophila) burmae Toda. But it differs from them in the pattern of terminalia (figs. 1-3) in detail, Epandrium pubescent, with ca. 3 setae in upper part, ca. 5 in lower part, ventral margin truncate, with ca. 2 small setae. Cercus oval, pubescent and setigerous, with tuft of short stout setae at caudoventral corner. Sur-stylus slender, with ca. 7 primary presisetae in nearly straight row on submedia to upper distal margin. Caudoventrally with several small setae. Aedeagus yellow, distally expanded like trumpet, dorsolaterally with 1 pair of slender, acute, sclerotized projections, laterally with long sclerotized area from submedial to subapical part. Gonopod (?) transparent, club-shaped with small hairs. Hypandrium with a pair of paramedian spines, hypandrial process elongate, apically somewhat pointed. Parameres fused to hypandrium, with ca. 2 sensilla.Holotype Tian Ping Mountain, Sangzhi County, Hunnan Province, 1400 m, .July 22, 1988. Collected by Liang X. C.. Paratypes: 2, ditto.All the types are deposited in Kunming Institute of Zoology, Academia Sinica.
