Fig. 7A-D

Drosophila (Drosophila) sonorae Heed & Castrezana, 2008: 28. Species "from Sonora": Wasserman 1982a: 95; 1982b: 54, 60; 1992: 508, 509.

Non-type material.

Strain E37.5c (Alamos, Sonora, Mexico), 1979: 2 ♂♂ (dissected), 8 ♀♀ (MZSP); 1 ♂, 3 ♀♀ (AMNH).

Male terminalia.

Epandrium (Fig. 7A ) microtrichose dorsally and on posterior medioventral area, with about 3 upper and 6 lower setae; ventral lobe expanded posterad (Fig. 7A ), partially covering surstylus. Cercus microtrichose, anteromedially fused to epandrium. Surstylus not microtrichose, with about 10 cone-shaped prensisetae, 3 outer and 4 inner setae. Hypandrium (Fig. 7A ) shorter than epandrium, anterior margin convex; posterior hypandrial process and dorsal arch absent; gonopod not microtrichose, devoid of seta, connected to paraphysis by membranous tissue. Aedeagus (Fig. 7A-D ) dorsodistally bifid and slightly turned dorsad, submedially expanded dorsoventrally; dorsal cleft along most of aedeagus length (Fig. 7B, C ); paraphysis not microtrichose, connected to gonopod by membranous tissue, subapically double-walled dorsally, and submedially bearing one setula on dorsal margin (Fig. 7D ). Aedeagal apodeme curved ventrad, slightly shorter than aedeagus and fused to it, posterodorsally bifid (Fig. 7C ). Ventral rod slightly shorter than paraphysis, dorsoventrally flattened.
