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

(Fig. 37)

Diagnosis. This species is very similar to P. subradiata (Okada, 1977) in the shape of paramere, but can be distinguished from the latter by having the vertical process of gonopod radiated apically (Fig. 37C); two basal bridges of aedeagal median rod fused to each other (Fig. 37C).

Description. Frons dark brown. Face brownish. Mesoscutum and pleura brownish yellow, with brown spots and pollinose pattern. Scutellum brownish yellow, with 1 pair of dark brown patches distolaterally. Male terminalia (Fig. 37): Epandrium pubescent anteroventrally, with ca. 14 setae on dorsal to posterolateral portion per side (Fig. 37A). Surstylus basally pubescent on outer surface, with ca. 6 wedge-like prensisetae on apical margin (Fig. 37B). Posterolateral lobe of hypandrium undeveloped and lacking pubescence (Fig. 37C). Paramere expanded and pubescent distally; apical and medial processes each with 1 tooth and 1 sensillum; basal process round apically (Fig. 37D). Vertical process of gonopod apically with 4 or 5 of projections per side (Fig. 37C). Aedeagal median rod submedially with 1 pair of small processes (pr in Fig. 37C) and 1 small projection (ps).
