Diagnosis. Projections at anterolateral corners of the cibarium longer than 1 / 2 width of cibarial, anterior margin (ch. 10 - 1; Fig. 2 C); mid-dorsally constricted epandrium (ch. 29 - 1; Figs 3 B, D, 4 B, 6 D, 7 E, 8 G, 9 F); less sclerotized, broad lobe-like surstylus (ch. 34 - 1; Figs 3 E, 4 B, 5 C, 6 D, 7 E, 9 F); hypandrium with a pair of anterolateral, inward extensions articulated to base of pregonite (ch. 42 - 1; Figs 3 C, F, 4 D, 5 E, 6 G, 7 F, 8 J, 9 I). Shared characters. Characters described as commonly seen across this subgenus (the Phortica foliiseta species complex at that time) by Chen et al. (2005 b) are not repeated here. Occipital setae on lower portion shorter than postocular setae (ch. 2 - 0; Figs 7 A, 9 A). Pedicel with only 1 thick seta (ch. 4 - 0; Figs 2 A, 4 A, 5 A, 6 A, 7 C, 8 A, 9 B). Clypeus medially pale (ch. 8 - 1; Fig. 8 F). Lateral membrane of proboscis scale-like patterned (ch. 13 - 1; Fig. 2 D). Prominent postpronotal seta 1. Epandrium not extended at anteroventral corner (ch. 30 - 1; Figs 3 D, 4 B, 6 D, 7 E, 8 G, 9 F). Surstylus completely or largely covered with epandrium (ch. 36 - 1; Figs 4 B, 7 E, 8 G, 9 F), with pubescence (ch. 38 - 0; Figs 3 E, 4 B, 5 C, 6 D, 7 E). Cercus longer than twice of width (ch. 39 - 0; Figs 3 B, D, 4 B, 5 C, 6 D, 7 E, 8 G, 9 F). Pregonite articulated to tip of aedeagal guide (ch. 54 - 1; Figs 3 G, 4 I, 5 G, 6 E, 7 G, 8 D, 9 C), without sensilla on apical portion (ch. 51 - 0; Figs 3 G, H, 4 C, 5 D, 6 E, 7 G, 8 I, 9 G). Phallapodeme vertically flat plate, with posterior, rod-like process apically articulated to aedeagal median rod (ch. 60,61 - 1; Figs 3 G, H, 4 C, 5 D, 6 E, 7 G, 8 I). Aedeagal sheath with more or less sclerotized postgonite (s) (ch. 64 - 1; Figs 3 F – H, 4 D, 5 D, E, 6 F, H, 7 F, 8 I – K, 9 G – I).
