Asymphyloptera View in CoL sp. 2: Sinclair, 1995: 686.

Type material. HOLOTYPE, ♂ labelled: “ USA:A[ri]Z[ona]:Cochise Co./ Chiricahua M[oun]t[ai]ns./ 1– 2.VI.1991 6500' [1980 m]/ East Turkey C[ree]k./ B.J. Sinclair BS9102”; “ HOLOTYPE / Asymphyloptera / chiricahua / Sinclair [red label]” ( CNC). PARATYPES: USA. Arizona: Same data as holotype (5 ♂, 6 ♀, CNC, USNM).

Additional material examined. 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 View FIGURES 8 – 12 ). 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 View FIGURES 1 – 3. 1 ); crossvein h distinct; base of wing with slender setulae along posterior margin. Halter light brown.

Male terminalia ( Fig. 11 View FIGURES 8 – 12 ): 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 View FIGURES 8 – 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 View FIGURES 4 – 7 , 17 View FIGURE 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.
