Regasilus huiracocha View in CoL sp. nov.

( Figs. 10–11 View FIGURE 10 View FIGURE 11 )

Diagnosis. Very similar to R. apu sp. nov., but the hind femur is not fully black, it usually has a faint reddish basal stripe dorsally. Besides, the mystacal macrosetae are wholly black, as well as the katatergal macrosetae. The epandrium is straight, although a pointing-down projection is present at apex ( Fig. 10B View FIGURE 10 ); the ejaculatory apodeme is large, and the phallus narrow ( Fig. 10D View FIGURE 10 ).

Description of male holotype ( Fig. 10A View FIGURE 10 ). Lengths. Body: 16 mm; wing: 11 mm.

Head. Similar to R. apu sp. nov., but mystacal macrosetae wholly black; proboscis yellowish setose, as well as lower side of occiput. Thorax. As in R. apu sp. nov. but yellowish setae on uppermost portion of anepisternum, besides katatergal macrosetae black. Wing ( Fig. 2 View FIGURE 2 ). Similar to R. apu sp. nov.; halter yellowish. Leg. Similar to R. apu sp. nov., but hind femur with a faint reddish basal stripe dorsally, besides, black macrosetae predominate on femora. Abdomen. Similar to R. aiapaec sp. nov., but with different terminalia. Terminalia ( Figs. 10 View FIGURE 10 B–C). Shining black; epandrium elongate and straight, with a pointing-down projection at apex; long black setae on base, yellowish towards the apex, with conspicuous spiny yellowish macrosetae on posterior margin present; hypandrium broad, with long black setae, excision at posterior margin subrectangular ( Fig. 10E View FIGURE 10 ); gonocoxite subtriangular, apex pointed, with a notch on internal margin and black long setae on external margin ( Fig. 10F View FIGURE 10 ); gonostylus curved upwards, usually visible on lateral view; phallus narrow, almost straight; ejaculatory apodeme wide in lateral view, large, extending to seventh segment ( Fig. 10D View FIGURE 10 ).

Female ( Fig. 11A View FIGURE 11 ). Similar to male, except terminalia ( Fig. 11B View FIGURE 11 ); spermathecae situated almost at base of seventh abdominal segment, similar to R. apu sp. nov., but slightly bigger; common duct as long as arms of furca; expulsory ducts twice as long as capsular ducts and about half the length of common duct ( Fig. 11C View FIGURE 11 ).

Etymology. A masculine noun in apposition, given to Huiracocha, the prehispanic main god in the Andean region of South America, revered as the creator of all things.

Distribution ( Fig. 20A View FIGURE 20 ). Peru, Department of Cuzco, Cosñipata Valley, cloud forest on the eastern slopes of the Andes.

Holotype condition. Good. Detached terminalia placed in microvial with glycerin and pinned along with the specimen.
