Drosophila (Drosophila) comosa Wheeler, 1968: 432

Male holotype.

Double mounted to a point, labelled: "Golfito Costa Rica / WB Heed HL Carson Jun Jul 1959 / HOLOTYPE Drosophila comosa Whlr. [pink label] / Drosophila comosa Wheeler", deposited in NMNH.

Male terminalia.

Epandrium (Fig. 9A ) distally microtrichose; upper setae absent; ca. 19 lower setae; ventral lobe distally sinuous, partially covering surstylus. Cercus mostly microtrichose, anteromedially fused to epandrium. Surstylus not microtrichose, with about 9 long, sharply pointed prensisetae, 12 outer and 15 inner setae. Decasternum as in Fig. 9B . Hypandrium (Fig. 9C ) remarkably developed, twice as long as epandrium, anterior margin convex; posterior hypandrial process and dorsal arch absent; gonopod not microtrichose, devoid of seta, submedially bearing a circular depression adjacent to inner margin; connected to paraphysis by membranous tissue. Aedeagus (Fig. 9D-H ) rounded at tip, subdistally expanded ventrad and with a pair of spurs pointed anterad (Fig. 9E-H ), dorsally convex at middle and shallowly concave beyond middle; dorsal cleft ca. 1/2 length of aedeagus (Fig. 9D, E ); paraphysis conspicuously narrow and curved laterad, not microtrichose, connected to gonopod by membranous tissue, distally double-walled and bearing one setula at the very tip (Fig. 9F ). Aedeagal apodeme about 1/3 aedeagus length and fused to it, rod-shaped, posterodorsally bifid (Fig. 9E ). Ventral rod vestigial, bifid (Fig. 9G, H ).
