( Figs. 1 A–C)

Locus typicus: USA, California, Los Angeles County, San Gabriel Mountains , San Gabriel Canyon , 800 m, maple mixed forest. Holotype: Male, 13.–19.iv.1996, leg. W. Mohrig, yellow trap ( PWMP) . Paratypes: 4 males, same data ; 7 males, 4.–9.iii.1996, same location ; 1 male, 7.–13.iv.1996, same location ; 4 males, 2.–16.iii.1997, leg. W. Mohrig, California, Los Angeles County, San Bernardino National Park, Silverwood Lake, mixed forest, 1200 m, Malaise trap; 1 male, 11.vi.–23.vii.1994, leg. E. Fuller, Canada, Alberta, Berland River at Hwy 40, 53.42°N, 118.20°W, pine forest, Malaise trap (PWMP, 1 male in PKHH, 1 male in MZH).

Description. Male. Head. Dark brown. Eye bridge 4 facets wide. 4th flagellomere with l/w-index 3.0, haired pale and longer than wide. Necks rather long. Palpus 3-segmented, short; basal segment with a slightly deepened sensory area and 2–3 bristles. Thorax. Brown. Scutum haired short and pale. Wings pale; R1= 2/3 R; c longer ½ w; y = x, bare; posterior veins bare. Haltere short, brownish. Legs brownish; tibial organ comb-like; middle and hind tibiae with one long spur, second spur reduced or absent; claws toothless. Abdomen. Brown, haired brownish. Hypopygium brown, ventral base closed, haired rather long but sparsely; gonocoxites strong, somewhat longer than gonostylus, haired sparsely at the inner ventral margin. Gonostylus flattened on inner side, with a minute apical tooth and 6–7 longer spines, located in the apical half of the inner side. Tegmen wide, apically with fine teeth. Body size: 2.5 mm.

Comments. The species is characterized by a very short apical tooth on the gonostylus and the subapical spines are much longer, 4–5 spines are located more in the middle of inner side, two at the level of apical tooth (or somewhat above). The flagellomeres are remarkably long. The species differs from Sc. subciliata Tuomikoski by less numerous but longer subapical spines whereas the apical tooth is short as well. The species belongs to the Sc. atomaria group.

Distribution. USA (California), Canada (Alberta).

* Awinita = fawn, Cherokee.
