Doratura lukjanovitshi Kusnezov, 1929: 177

Diagnosis. The species is closely related to D. gravis ; it displays similar but more slender styles ( Fig. 26H ) with the central tooth directed ventrad, and a very slim aedeagus (26D, E). The hind margin of the female pregenital sternite ( Fig. 20H ) is straight. In rare cases it displays a very indistinct median notch.

Distribution ( Fig. 59 ). We studied material from Mongolia and Russia (Central Siberia). Apparently, there are no records for further countries.

Remarks. Kusnezov inserted D. lukjanovitshi in the original description near D. ivanovi (= impudica ) and D. stylata . The identification of Doratura material from Mongolia by Dlabola (1965) as D. lukjanovitshi is correct. Dlabola figured the styles of this material, which resemble the styles of D. gravis . However, many specimens in his collection identified by himself as D. lukjanovitshi belong to D. stylata or D. gravis .
