2. Ditaeniella Sack, 1939 (Figs. 5, 7, 34, 66) Ditaeniella Sack, 1939: 37. Type species: Sciomyza grisescens Meigen, 1830 (original designation). Diagnosis. Frons matt with only 1 orbital seta. Prosternum with a few setulae. Propleural seta distinct. Wing hyaline without spots or reticulated pattern. Remarks. Of the 4 described species, only Ditaeniella grisescens (Meigen, 1830) is known from the Palearctic Region (its range extends into the Oriental Region); the other 3 species are Nearctic or Neotropical. Rozkošný (1987) reported D. grisescens from China, and it is still the only species of Ditaeniella known from China. About 10 males and 5 females were collected both in the Palearctic Region (Heilongjiang, Inner Mongolia, Beijing, Hebei, Xinjiang, Tibet) and the Oriental Region (Yunnan) of China, which is consistent with the known distribution of the genus in the Eastern Hemisphere.
