Diagnosis. Dorsomedial, tentorial apodeme ≥ 2/3 basal, parallel portion of dorsolateral, tentorial apodeme (ch.1-0); abdominal tergites III and IV unicolor (ch.21-3); epandrium with triangular or hook-like projection on anteroventral margin (ch.31-2; Fig. 3B); pregonite (Fig. 3C) not strongly sclerotized (ch.43-2), plate-like (ch.44-0), with basal extension nearly rectangular to main body and apically broad (ch.49-2).
Shared characters. Arista with dorsal but no ventral branches; apical, leaf-like expansion apically with small, awn-like projection. Palpus with hollow-shaped sense organ (ch.9-2). Some anterior, cibarial, medial sensilla short, apically blunt, peg-like (ch.11-1). Prementum without pubescent patches (ch.12-0). Pseudotracheae in labellum 6 per side (ch.14-2). Setulae just before prescutellar acrostichal setae somewhat longer than other acrostichal setulae (ch.15-1). 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). Abdominal sternite III longer than wide (ch.22-0), not wider than IV (ch.23-0); IV not wider than long (ch.24-0); V wider than long (ch.25-1); III–V without dense setulae on medial surface (ch.26–28-0). Setae on and/or near ventral margin of epandrium (Fig. 3B) not denser than those on other portions (ch.32-0), longer than others (ch.33-1). Surstylus (Fig. 3B) without expansion at caudoventral corner (ch.35-0), with peg-like teeth (ch.37-0). Hypandrium symmetric (ch.40-0); phragma as narrow as lateral gonocoxites (ch.41-1). Pregonite (Fig. 3C) not serrated on ventrodistal portion (ch.50-0), with sensilla on submedial and basal portions (ch.52,53-1). Aedeagal, outer membrane bearing neither spiny ornamentation nor apical, long, narrow tube (ch.55-1, ch.57-0); median rod entirely or partly strongly sclerotized (ch.58-0); free sclerite absent within outer membrane (ch.59-0). Posterior, rod-like process of phallapodeme not longer than aedeagal median rod (ch.62-0). Aedeagal sheath with lateral lobes bearing strongly sclerotized postgonites (ch.65-1); sclerotized, posterior postgonites medially separated from each other (ch.66-0).
Included species. This species group comprises African species: Phortica (Ashima) angulata Prigent & Chen; P. (A.) curvispina Prigent & Chen *; P. (A.) machoruka Prigent & Chen; and P. (A.) unispina Prigent & Chen *. * The assignment was judged from the original descriptions by Prigent & Chen (2008).
