Kanmiya, 1971
, but can be separated from the latter by the following features: gena 0.25 times as deep as eye in lateral view; palpus largely black; surstylus clavated in lateral view. In
D. nartshukae
, the gena is 0.3–0.4 times as deep as eye in lateral view; the palpus is entirely yellow; and the surstylus is nearly parallel in lateral view (

).
