( Fig. 19 C–D)

Locus typicus: USA, Arizona, Cochise County, Huachuca Mts. , Ash Cyn. Rd. , 31.39°N, 111.24°W, oak-pine woodland. Holotype: Male , 5.–30.viii.1993, leg. N. McFarland, Malaise trap ( PWMP).

Description. Male. Head. Dark brown. Eye bridge 3 facets wide. 4th flagellomere with l/w-index 1.8, haired longer than wide, necks rather long. Palpus 3-segmented, short; basal segment with slightly deepened sensory area and 1–2 bristles. Thorax. Brown; scutum haired pale. Wings pale; R1 = ½ R; c shorter ½ w; y nearly 1/ 2 x, bare; posterior veins bare. Haltere short, brownish. Legs yellowish brown; tibial organ small, comb-like; claws toothless. Abdomen. Brown, haired pale. Hypopygium brown; gonocoxites longer than gonostylus, inner ventral margin haired very sparsely. Gonostylus elongated, without tooth; with 3 small apical spines. Tegmen wide. Body size: 2 mm.

Comments. This small species is similar to Sc. awanatae in the shape of gonostylus with three apical spines. It differs by pale body hairs, shorter flagellomeres, shorter c and a very sparsely haired ventral side of the hypopygium. The species belongs to the Sc. inesae group.

Distribution. USA (Arizona).
