Discussion

Remarks.Ablabesmyia (Karelia) pictipes (Kieffer) and A. (K.) nilotica (Kieffer) have been known from the Palaearctic region. The female antenna of the former has 11 segments including the pedicel (Freeman 1955, Fittkau 1962), and the tibia of the latter has four black rings (Freeman 1955). The present species can be separated in the female antenna with 12 segments, and the tibia with three rings. Furthermore the species obviously differs from all the known species of Karelia in the prominent lateral lobe in the male aedeagal complex, and the apically clubshaped aeropyle in the pupal thoracic horn.
