Male holotype. Double mounted to a point, labelled: "Lancetilla 51.15 / Apr 4, 54 WBHeed / Rep. de Honduras / HOLOTYPE [red label] / Drosophila sticta Wheeler", deposited in NMNH. Male terminalia. Epandrium (Fig. 8A ) dorsodistally microtrichose, with ca. 2 upper and 8 lower setae; ventral lobe posteriorly dorsally membranous, not covering surstylus. Cercus slightly microtrichose on dorsomedial area, linked to epandrium by membranous tissue. Surstylus microtrichose distally on central area, with about 8-9 cone-shaped prensisetae, 4-5 outer and 9-13 inner setae. Decasternum as in Fig. 8B . Hypandrium (Fig. 8C-E ) longer than epandrium, anterior margin convex; posterior hypandrial process absent; dorsal arch vestigial, not projected posterad; gonopod not microtrichose, fused to paraphysis, bearing 1-2 long setae on anterior inner margin. Aedeagus (Fig. 8F-J ) apically trifid (in dorsal and ventral views, Fig. 8F, J ), subapically dilated; the dilatation with a pair of ventral spurs and a dorsal membranous area covered with tiny spines (Fig. 8F-J ); dorsal cleft reduced to a small anterior opening (Fig. 8F, G ); paraphysis long, conspicuously narrow, slightly widening towards distal end, not microtrichose, fused to gonopod, submedially bearing two setulae on anterior inner surface (Fig. 8E ). Aedeagal apodeme 1/3 aedeagus length and fused to it, rod-shaped, posterodorsally bifid (Fig. 8G ). Ventral rod vestigial (Fig. 8I, J ). Figure 8.
