Drosophila (Drosophila) arizonae Ruiz, Heed & Wasserman, 1990: 39.

Non-type material.

Strain E2.2 (Navojoa, Sonora, Mexico), 1979: 2 ♂♂ (dissected) plus 22 ♂♂, 36 ♀♀ (MZSP); 1 ♂, 3 ♀♀ (AMNH).

Male terminalia.

Epandrium (Fig. 5A ) distally microtrichose, except lobe; bearing about 8 upper and 9 lower setae; ventral lobe partially covering surstylus; ventral margin concave; anterior and distal end sharply pointed. Cercus mostly microtrichose; anteromedially fused to epandrium. Surstylus not microtrichose, with about 12-13 cone-shaped prensisetae, 2 outer and 11 inner setae. Decasternum as in Fig. 5A . Hypandrium (Fig. 5A ) shorter than epandrium, anterior margin convex; posterior hypandrial process and dorsal arch absent; gonopod not microtrichose, connected to paraphysis by membranous tissue, bearing one seta on anterior inner margin. Aedeagus (Fig. 5B-D ) short, weakly sclerotized at tip, submedially bearing a single ventral, anterad pointed spur (probably by fusion of two); dorsal cleft ca. 1/3 length of aedeagus (Fig. 5B ); paraphysis not microtrichose, connected to gonopod by membranous tissue, distally double-walled, submedially bearing 1 setula adjacent to dorsal margin (Fig. 5C ). Aedeagal apodeme curved ventrad, slightly shorter than aedeagus and fused to it, laterally flattened, posterodorsally bifid (Fig. 5B ). Ventral rod as long as paraphysis, dorsoventrally flattened, completely fused to aedeagal apodeme (Figs 5B-D ).
