Description
This species is distinguished from congeners by the following combination of characters: Small shore flies, body length 1.30–1.95 mm. Head: Medial facial carina above facial prominence shallow; labella broad, fleshy, shorter than mediproboscis; clypeus microtomentose, usually gray.
Thorax: Presutural supra-alar seta present. Pleural area lacking stripes. Wing with costal vein ratio 0.32–0.38; M vein ratio 0.43–0.50. Legs blackish brown to black; midtibia bearing numerous, erect setae along dorsal surface.
Abdomen: Male 5th sternal flap in lateral view (Fig. 70) moderately elongate, bearing 3 long setulae apically; 5th medial process in lateral view (Fig. 70) very elongate, nearly straight, apex widened, bearing 4–5 apical setulae. Male terminalia (Figs 69, 71–73): Epandrium in posterior view (Fig. 69) rounded dorsally, constricted laterally at base of surstyli; epandrium in lateral view (Fig. 73) somewhat rectangular dorsally with anterior and posterior margins parallel sided, ventral portion with an anterior bulge and a narrow, sharp incision at about level of base of surstylus; cerci in posterior view (Fig. 69) approximate dorsally then extended laterally to form a lyre-like structure that curves laterally than ventrally, apex of cercus bearing 2 short setulae; cercus in lateral view (Fig. 73) shallowly sinuous, nearly parallel sided, apex not expanded, bluntly rounded; surstyli (ventral extensions of epandrium) in posterior view as relatively wide at base third, thereafter ventrally abruptly narrowed, especially along medial margin, to form an elongate process that is slightly spatulate apically, apical portion bearing several short setulae; surstylus in lateral view (Fig. 73) moderately narrow, slightly expanding with apex obliquely pointed, anteroventral surface of apex shallowly emarginate, bearing several, very short setulae; aedeagus in ventral view (Fig. 71) elongate, narrowly ovate, very slightly tapered apically, in lateral view (Fig. 72) elongate, nearly parallel sided, apex bluntly rounded; phallapodeme in lateral view (Fig. 72) triangular, keel abruptly tapered to narrow, digitiform apex; gonite in ventral view (Fig. 71) almost bar-like, wider basally, apex broadly rounded, with short, medial process, apex bearing setula, in lateral view (Fig. 72) only slightly wider basally, nearly straight, slightly tapered to blunt apex that is medially notched, producing a shallowly bifurcate apex, anterior and posterior process of shallow bifurcation bearing a single setula.
Type material
The holotype male is labeled “USA. OREGON. Baker: Goose Creek [35 km E Baker City] (44°49.2'N, 117°27.79'W; 825 m), 7Jun2006, D. & W. N. Mathis/HOLOTYPE ♂ Allotrichoma wallowa W. Mathis & T.
