Phortica (Phortica) imbacilia Gong & Chen, sp. nov.

(Fig. 34)

Diagnosis. This species is somewhat similar to P. eugamma (Toda & Peng, 1990) and P. gamma (Toda & Peng, 1990) in having the male abdominal sixth tergite not extended on posterolateral corners and aedeagal outer membrane with minute, transparent spinules, but can be distinguished from the above-mentioned two species by having the aedeagal median rod distally with 1 spine-like process and 1 deeply bifurcated process per side, basally without didymous, rod-like processes (Fig. 34C); paramere curved basally (Fig. 34D).

Description. Frons dark brown to black above, brown below. Face brown. Mesoscutum, pleura and scutellum brown, with dark brown to black patches and pollinose patterns. Male terminalia (Fig. 34): Epandrium pubescent anteroventrally, with ca. 7 setae on dorsal to posterolateral portion per side (Fig. 34A). Surstylus lacking pubescence on outer surface, with several wedge-like prensisetae on apical margin (Fig. 34B). Posterolateral lobe of hypandrium undeveloped and lacking pubescence (Fig. 34C). Paramere with 1 sensillum and 3 teeth on apical process; medial and basal process slender and glabrous (Fig. 34D).
