Genus Scatomyza Fallén, 1810

Figs 31 , 67 , 70, 71, 76, 93–99.

DIAGNOSIS. Medium-sized flies (6–11 mm long). Proepisternum is covered with hairs at middle or in anterior part. Anepisternum is covered with hairs completely or almost completely, with hairs posterior to anterior spiracle. Katepisternum with a strong seta in upper posterior corner. Postmetacoxal bridge present ( Fig. 31 ). The presence of postmetacoxal bridge easily differs this genus from others genera of Scathophagidae .

REMARKS. There are three species in Russia: S. magnipennis (Portschinsky, 1887) , S. mellipes (Coquillett, 1899) and S. scybalaria (Linnaeus, 1758) .

S. magnipennis s known in Russia from Altai and Buryatia [ Gorodkov, 1967]; there are specimens from Altai in ZMUM (1 ♂, Kuray Ridge , 2500–2700 m (50.33ºN 87.75ºE), 3.VII.2008, Barkalov; 7 ♂♂, 4 ♀♀, Kosh-Agach env. (50.01ºN 88.66ºE), 1750 m, 2– 4.VII.2016, N. Vikhrev) .

S. mellipes is noted in Russia from Far East [ Gorodkov, 1986; Ozerov, Krivosheina, 2014b].

S. scybalaria is widespread species in Russia. It is known from European part to Sakhalin Oblast [ Gorodkov, 1986; Ozerov, Krivosheina, 2014b].
