2. Aedeagus reaches the level of bases of seta h3. (Females unknown) ............................. .................................................................................... D. allocaulus (Gaud & Mouchet)

­ Aedeagus only reaches the level of anterior end of terminal cleft; females with dilation on primary duct near the head of spermatheca ........ D. glyphonotus (Gaud & Mouchet)
