Allied to D. vagans Loew, 1864 (Europe), in having wings basally black and ante- 

 riorly fuscous, but differs in the less distinct dark cloud on posterior crossvein and in 

 the shape of egg-guide (distally not narrowing in vagans, Okada, 1960b) and ventral 

 receptacle (apical invagination shallow triangular in vagans, Okada, 1960b).
