2.2. Phortica (Ashima) tanabai species subgroup, new

Diagnosis. Prementum with a pair of patches of pubescence (ch.12-1; Fig. 6B ); aedeagal, outer membrane ornamented with somewhat long, conical spines (ch.55-0, ch.56-2; Figs 6E,G , 7G,H ).

Shared characters. Some interfrontal setulae as long as lowest setulae on ocellar triangle (ch.3-0; Fig. 7B ). Arista apically with leaf-like expansion (ch.7-1; Figs 6A , 7C ). Setulae just before prescutellar acrostichal setae somewhat longer than other acrostichal setulae (ch.15-1). Fore and mid tibiae entirely yellow (ch.17,18-0). Abdominal sternites III–V wider than long (ch.22,24,25-1; Figs 6C , 7D ); III widest among sternites (ch.23-1; Figs 6C , 7D ), with dense setulae on medial surface (ch.26-1; Figs 6C , 7D ). Pregonite not concave on dorsosubapical margin of apical knob (ch.48-0; Figs 6E , 7G ), without basal extension (ch.49-0; Figs 6E , 7G ). Posterior, rod-like process of phallapodeme not longer than aedeagal median rod (ch.62-0; Fig. 6E ). Aedeagal sheath without lateral lobes bearing strongly sclerotized postgonites (ch.65-0; Figs 6F , 7F ).

Included species. Phortica (Ashima) huiluoi Cheng & Chen *; P. (A.) mediarista ; P. (A.) tanabei ; P. (A.) akutsui sp. nov.; and P. (A.) halimunensis sp. nov. * The assignment was judged from the original description by Cheng et al. (2008).
