USA . Arizona : Cochise Co., 12.5 km S Sierra Vista Ramsey Cyn, 10– 17.xii.1986 , MT, oak/pine/juniper, B.V. Brown (1 ♀, CNC ). Recognition . This species may be distinguished by dark pleura and legs; narrow, elongate surstylus with rounded apex; apex of phallus setose and arched anteriorly. Description . Male . Postpedicel globular with long, slender apical extension, arising subapically ( Fig. 10 ). Ocellar setae stout, similar in length to postpedicel extension. Labrum slightly shorter than clypeus; palpus brown, subequal to labrum, tapered to slender apex. Pleura dark brown with thin bluish pruinescence. Chaetotaxy very stout; 1 pprn short, very slender; 2 npl, lower slender and shorter; 4 dc, anterior dc offset; 2 apical sctl, 1.25X longer than prescutellar dc, lacking lateral sctl. Legs dark brown; fore and mid femora with antero- and posteroventral rows of pale, slender setae, subequal in length to width of femur; fore tibia with biserial row of erect setae. Wing length 1.8–2.1 mm ( Fig. 2 ); crossvein h distinct; base of wing with slender setulae along posterior margin. Halter light brown. Male terminalia ( Fig. 11 ): Cercus with short anterior lobe and long, slender posterior lobe. Hypandrium prolonged as broad, paired postgonites; apical margin of postgonite extended anteriorly, narrow, hook-like. Epandrium narrow, with short setae on apical half. Surstylus long, slender, slightly arched lobe; apex rounded, extended beyond phallus. Phallus slightly arched anteriorly; apex rounded with microsetae; ejaculatory apodeme narrow, not expanded. Female . Similar to male except as follows: lacking long ventral setae on fore and mid femora and fore tibia. Sternite 8 extended beneath cercus; posterior margin of sternite 8 invaginated, forming wide plate with lateral sclerite extending to posteroventral margin of tergite 8 ( Fig. 12 ). Spermatheca elongate, slender. Etymology . Named after the type locality, the Chiricahua Mountains of southeastern Arizona. Distribution . Known only from the type locality in southeastern Arizona ( Figs 5 , 17 ), a small stream shaded by oaks, juniper and pine. This was the first known Nearctic record of the genus ( Sinclair 1995 ), collected during the 1991 field meeting of the North American Dipterists Society.
