Ulidia sp. cf. erythrophthalma Meigen, 1826

( Fig 15 )

Material examined. China: Xinjiang: 3Ƥ: Tulufan, 20–140m, 8. VI. 1956 (Li Changqing) ( IZCAS), Xinjiang: 2Ƥ: Alaga, RuoQiang, 850m, 8. V. 1960 (Wang Shuyong) ( IZCAS).

Diagnosis. Frons black with the middle part dark-brown, subshining and shallowly dimpled. Head higher than wide, not expanded anteriorly. Frons distinctly wider than eye, almost parallel-sided. Gena about 1/4 times as high as eye. Parafacial not expanded, at most as wide as flagellomere 1. Antennae with 1st flagellomere round apically, slightly longer than wide. Thorax shining black; acrostichal seta present. Wing hyaline with yellowish tinge, postero-dorsal extension of cell bcu short, slightly longer than the transverse section of vein Cu2. Halter yellownish-brown. Upper calypter yellowish. All setae dark-brown. Legs black except mid- and hindtarsi brownish yellow. Abdomen entirely shining black.

Notes. This species belongs to the group of species superficially similar to European U. erythrophthalma , which also includes U. albidipennis Loew , U. parallela Loew , U. nigripennis Loew and possibly some other species that can be identified with certainty only from the structure of the phallus, whereas females are indistinguishable. Consequently, it is impossible to place these Chinese specimens with certainty now.

Distribution. China (Xinjiang).
