Drosophila (Drosophila) nakanoi Zhang et Toda, 1995

    Diagnosis: Body color generally brown in both sexes, without strong sexual dimorphism. Fore femur with row of ca. 8 (7-11) stout, black, ctenidial spines on distal 1/2 of inner side. Acrostichal setulae in 10 rows. Male fore tarsus anteriorly with long, recurved setae, 1st tarsomere with thick hair tuft on distal 2/3 of inner side. Aedeagus ventrolaterally with 1 pair of sclerotized, apically poited edges.

    Remark: The nomenclators assign this species to the D. hypocausta species-subgroup, based upon combination of the following characters: hypandrium with 1 pair of distinct hypandrial processes; dorsal process of aedeagus not differentiated; and paramere completely fused to hypandrium, althouth this species has the ctenidial spines on inner side of fore femur and does not show the distinct sexual dimorphism in body color. This species can be distinguished from other members of the D. hypocausta species-subgroup by the other characters designated in the diagnosis.

    Distribution: Sumatra.
