3. Phortica (Ashima) nigrifoliiseta species group, new

Diagnosis. Pseudotracheae in labellum 7 per side (ch.14-1; Fig. 9C); aedeagal, outer membrane apically with long, narrow tube (ch.57-1; Figs 6H, 8I); aedeagal, median rod moderately sclerotized (ch.58-1; Fig. 8K).

Shared characters. Some interfrontal setulae as long as lowest setulae on ocellar triangle (ch.3-0). Arista with 1–3 dorsal branches (ch.5-1; Figs 8A, 9B) and apical, leaf-like expansion (ch.7-1; Figs 8A, 9B). Some anterior, cibarial, medial sensilla short, apically blunt, peg-like (ch.11-1; Fig. 8C). Prementum without pubescent patches (ch.12-0; Fig. 9D). Setulae just before prescutellar acrostichal setae somewhat longer than other acrostichal setulae (ch.15-1; Fig. 8B). Mid and hind femora and all tibiae entirely yellow (ch.16–19-0). Apical, downward curved setula on fore tarsomere V stout, as long as tarsomere V (ch.20-1; Fig. 8D). Caudal bands on tergites III and IV medially interrupted/constricted (ch.21-2). Abdominal sternite V wider than long (ch.25-1; Figs 8E, 9E). Epandrium widely round on ventral margin (ch.31-1; Figs 8G, 9F); setae on and/or near ventral margin of epandrium longer than those on other portions (ch.33-1; Figs 8G, 9F). Surstylus without expansion at caudoventral corner (ch.35-0; Fig. 9F). Hypandrial phragma as narrow as lateral gonocoxites (ch.41-1; Figs 8 I–K, 9G–I). Pregonite (Figs 8I, 9G) rod-like, with apical knob (ch.44-1); apical knob without fine serrations (ch.45-0). Aedeagal free sclerite absent (ch.59-0; Figs 8 I–K, 9G–I). Posterior, rod-like process of phallapodeme not longer than aedeagal median rod (ch.62-0). Aedeagal sheath and/or postgonites asymmetric (ch.63-1; Figs 8J, 9I), with lateral lobes bearing strongly sclerotized postgonites (ch.65-1; Figs 8 I–K, 9G–I).
