Genus Dichopygina Vilkamaa, Hippa & Komarova, 2004

Type species: Bradysia (Chaetosciara) triseriata var. nigrohalterealis Frey, 1948: 61 , 81. Literature: Menzel & Mohrig (2000): 213, 220‒121; Vilkamaa et al. (2004): 108‒120; Mohrig et al. (2013): 199; Shin et al. (2013): 835.

Diagnostic characters. The genus has been diagnosed by Vilkamaa et al. (2004). Additionally we like to state, that the genus is characterized by elongate gonostylus, mostly concaved in the apical half (rarely winged), having a short apical tooth and several (4‒13) longer spines at the inner side, often inserting from the apex to the base, without whiplash-like bristles. The ventral base of the hypopygium is more or less v-shaped and the tegmen more or less rounded. Palpus 3-segmented. The basal segment of palpus has one bristle (rarely two) but no deepened sensory pit. Flagellomeres are medium-sized. Posterior wing veins are without macrotrichia. Posterior pronotum is bare and fore tibiae have a horseshoe-like tibial organ. Claws are toothless.
