Species "from Navojoa": Wasserman 1982a : 95-98; 1982b : 54, 57, 59. Non-type material. strain E2.1 (Navojoa, Sonora, Mexico), 1979: 2 ♂♂ (dissected) plus 23 ♂♂, 14 ♀♀ (MZSP); 1 ♂, 3 ♀♀ (AMNH). Male terminalia. Epandrium (Fig. 6A ) dorsally microtrichose, slightly microtrichose on posterior medioventral area, with about 2 upper and 9 lower setae; ventral lobe narrow, distally round, not covering surstylus. Cercus mostly microtrichose, anteromedially fused to epandrium. Surstylus not microtrichose, with about 11-12 cone-shaped prensisetae, 1 outer and 3 inner setae. Decasternum as in Fig. 6A . Hypandrium (Fig. 6A ) slightly 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. 6A-D ) distally expanded dorsoventrally and bearing a bulbous, membranous, and microtrichose area; submedially bearing a single ventral, anterad pointed spur (probably by fusion of two); dorsal cleft ca. 4/5 length of aedeagus (Fig. 6B, C ); paraphysis triangle-shaped, not microtrichose, connected to gonopod by membranous tissue, submedially bearing one setula on dorsal margin (Fig. 6D ). Aedeagal apodeme shorter than aedeagus and fused to it, laterally flattened, dorsodistally bifid (Fig. 6B, C ). Ventral rod as long as paraphysis, dorsoventrally flattened, completely fused to aedeagal apodeme (Fig. 6D ). Figure 6.
