: Antenna mostly dark gray; parafacial silvery white, concolorous with facial coloration; gena-to-eye ratio 0.17. Thorax: Wing with costal vein ratio 0.72-0.78; M vein ratio 0.52-0.54. Forefemur lacking a distinctive, comb-like row of stout setulae along anteroventral surface; tibiae mostly gray. Abdomen: Tergites 3-4 with wedge-shaped silvery-gray areas. Male terminalia (Figs 120-123): Combined structures generally elongate, in posterior view height more than twice width, generally sparsely setulose dorsally, setulae becoming sparse or lacking ventrally; epandrium lacking dorsal arch above cerci, in posterior view (Fig. 120) with basal 1/2-2/3 quadrate, thereafter ventrally narrowed as a taper to apex, apex with medioapical, small, U-shaped notch, in lateral view (Fig. 121) very elongate, moderately narrow with apical 3/4 straight, nearly parallel sided, basal 1/3 wider, somewhat rectangular; aedeagus in lateral view (Fig. 123) tubular, very elongate, narrow, more than 6 times longer than wide, mostly parallel sided, apical portion tapered to broad point, ventral view (Fig. 122) narrow, elongate, apical 1/8 tapered to rounded apex; phallapodeme in lateral view (Fig. 123) irregularly crescent shaped, more elongate and narrow toward base of aedeagus, keel elongate along most of phallapodeme but not extended more than width of phallapodeme, process toward hypandrium short, pointed, in ventral view (Fig. 122) somewhat I-shaped with unequal crossbars; gonite in lateral view (Fig. 123) as a very shallowly curved to sinuous, rod-like process, about equal in length to phallapodeme, in ventral view (Fig. 122) very shallowly curved to straight, slightly tapered at both apices; hypandrium in lateral view (Fig. 123) narrowly developed, parallel sided, length 3/4 that of aedeagus, in ventral view (Fig. 122) length about twice basal width, tapered from posterior to rounded, more narrowed anterior margin, deeply and narrowly notched anteromedially, posterior margin moderately deeply U-shaped, lateral margins slightly flared laterally.
