Drosophila (Drosophila) guayllabambae Rafael & Arcos, 1988: 167.

Non-type material.

Wild-caught male coded C50, labelled "PERU Cuzco, 1 km NE E.F. [ Estación Ferrocarril] Machu Picchu, 13°07'S, 72°32'W, C.R. Vilela coll., 02.III.1984 / Drosophila guayllabambae C.R. Vilela det."

Male terminalia.

Epandrium (Fig. 3A ) posteriorly microtrichose, except lobe; bearing ca. 4 upper, 2 median and 12 lower setae; ventral lobe triangle-shaped, partially covering surstylus. Cercus mostly microtrichose, anteromedially fused to epandrium (Fig. 3A, B ). Surstylus not microtrichose, with about 13 cone-shaped prensisetae, 6 outer setae and 8 inner setae. Decasternum as in Fig. 3B . Hypandrium (Fig. 3C ) shorter than epandrium, anterior margin convex; posterior hypandrial process and dorsal arch absent; gonopod not microtrichose, linked to paraphysis by membranous tissue, bearing one seta on anterior inner margin. Aedeagus (Fig. 3D-H ) with a pair of pointed, ventral, long spurs on subdistal margins, slightly bifid dorsally at tip (in dorsal and ventral views, Fig. 3D, H ), blunt and slightly expanded distally (in lateral view, Fig. 3F ); dorsal cleft ca. 2/3 length of aedeagus (Fig. 3E ); paraphysis not microtrichose, anteriorly narrow, distally wide and double-walled, linked to gonopod by membranous tissue, subdistally with 1-3 setulae at dorsal margin (Fig. 3D, E, G, H ). Aedeagal apodeme about half aedeagus length and fused to it, curved ventrad, laterally flattened, posterodorsally bifid (Fig. 3E ). Ventral rod slightly shorter than paraphysis, dorsoventrally flattened, completely fused to aedeagal apodeme.
