Description: Length of each forewing 2.9–3.1 mm (n = 10). Specimens in alcohol with compound eyes black, legs brown, dorsal surfaces of thorax and abdomen dark brown, ventral surfaces pale cream. Forewings with forks II, III, IV, and V present, crossveins s, r, m-cu and m zigzagged; hind wings with forks II, III, and V present, R 1 atrophied, but discernable, R 2+3 ending at Sc (Figs 7e, 7f).
Male genitalia: Tergum IX and sternum IX distinctly separated from each other (Fig. 5a). Apical sclerites discernible in dorsal view (a.s. in Fig. 5d), each with lower margin produced into triangular lobe at midlength. Preanal appendages subrectangular in lateral view (pre.app. in Fig. 5a), slightly clavate in dorsal view (pre.app. in Fig. 5d), with thickened bases and apices. Coxopodites fused and indistinguishable from basal plate (b.p. in Fig. 5e). Harpagones setose, bifid, in ventral view pincer-shaped (har. in Fig. 5e), each with lateral branch wider than mesal one. Phallic apparatus with phallotheca elliptical; endotheca with base having pair of processes (Figs 5b, 5c, 5e), and apex having apical hook in lateral view (Fig. 5a), and with ejaculatory duct opening anterior to apical hook.

Distribution: China (An-hui, Fu-jian, Hu-bei, Jiang-xi, Si-chuan, and Zhe-jiang).
Remarks: The species has tergum IX incompletely fused with preanal appendages and is discernible in both dorsal and ventral views. Furthermore, the species has relatively simple harpagones. Therefore, we treat it as a member of Schmid’s P. pusilla Species Group.
