【摘要】 <正> 折蜂麻蝇属Oebalia Robineau-Desvoidy,1863隶麻蝇科蜂麻蝇亚科,由于雄性尾器形态特殊而极易辨认;过去仅知分布于欧洲及亚洲北部。本属长期以来以Ptychoneura Brauer et Bergenstamm,1889为属名,后经(1963)订正,确认Ptychoneura仅为本属的一个亚属。本文就青海省蝇类调查中发现的一新种进行描述,这也是本属在我国首次报道。更多还原

【Abstract】 The Eurasian genus Oebalia R.-D. may be easily recognized by a pev that orm in male tenninalia. It has not been recorded hitherto in our country. In this paper, a newspecies from northwest China is described.Oebalia (s.str.)pedicella, 禄sp.nov.(Fig. 1)Body length 5 mm. Very similar to Oe. (s.str.) sachtlebeni Rohdendorf in external features, The new species, however, possesses a leaf-like anal cercus, the middle portion of which is as thin as a pedicle; whereas in Oe. sachtlebeni, the anal cercus is sickle-like.It is also allied to Oe. unistriata Rohdendorf, but quite different in the maculation of abdomen. The new species is marked with a definite black median stripe on the 5th tergite, while there is no maculation on that of Oe. unistriaia.Holotype (?) , Banma, Qinghai, 1981-Ⅵ-10, Coll.
