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.
