This species is distinguished from congeners by the following combination of characters: Small shore flies, body length 1.30-1.85 mm. Head: Antenna mostly dark gray; parafacial silvery white, concolorous with facial coloration. Gena moderately high, height usually slightly higher than length of basal flagellomere; gena-to-eye ratio 0.71-0.73. Thorax: Wing hyaline; costal vein ratio 0.66-0.82; M vein ratio 0.45-0.50. Hindtibia bearing an apical black seta ventrally. Abdomen: Tergites lacking wedge-like marking laterally but tergites 2-4 with wide medial area extensively dark slate gray to black; tergite 5 light gray to silvery gray with undifferentiated posterior margin, uniformly colored; medial coloration on tergites 1-4 narrow, sometimes only a stripe, slightly darker than color of lateral margins. Male terminalia (Figs 149-152): Combined structures generally elongate, in posterior view (Fig. 149) height about 2.5

width; epandrium with dorsal arch above cerci attenuate, not connected, dorsal 1/3-1/2 somewhat quadrate with angles rounded, ventral portion as 2 digitiform, thick, parallel lobes that connect subapically for a short distance, ventral margin moderately narrowly rounded with deep, very narrow, apical incision medially, dorsal half bearing setulae, in lateral view (Fig. 150) mostly parallel sided with anterior shallowly sinuous, apical 1/3 tapered to sharply rounded apex; cerci short, in lateral view height about twice width (Fig. 150), narrowly semicircular, not attached with epandrium; aedeagus in lateral view (Fig. 152) elongate, with length of sclerotized portion about 5

but can be distinguished from either of these two species by having a hindtibia that bears a black setula ventrally near the apex, a nearly parallel-sided ventral epandrial process, and by having a more robustly developed hypandrium, especially the anterior two-thirds (Fig. 151). In addition, the apical portion of the aedeagus is frequently greatly inflated (best seen in lateral view; Fig. 152)
