Diagnosis. Arista apically with distinct, leaf-like expansion narrower than long and apically tapering and pointed and 2–3 long and 1–3 minute branches dorsally and ventrally, respectively; longest, dorsal branch longer than longest seta on pedicel [“Fig. 19 (mislabeled as 18 on the plate)” in Cheng et al. 2008]; posterior postgonite apically blunt.

Supplementary description (not repeating characters common to P. pavriarista ). Supracervical setae 8–11. Dorsomedial, tentorial apodeme slightly longer than 1/2 basal, parallel portion of dorsolateral, tentorial apodeme. Cibarial, medial sensilla approximately 8 per side; posterior sensilla 6–7 per side. All tarsi with gray tarsomeres IV and V. Abdominal sternite III wider than long (ch.22-1), widest among sternites (ch.23-1), with dense setulae on medial surface (ch.26-1).

The antisymmetry is observed in the postgonites: in A-type, the left lateral lobe bears 2 anterior postgonites, and the right lobe 1 posterior and 1 anterior postgonites (the holotype; “ Fig. 3 View FIGURE 3 ” in Máca & Lin 1993b); but in B-type, vice versa (“ Fig. 4 View FIGURE 4 ” in Máca & Lin 1993b).

Specimens examined. Japan: 1♂ (A-type), Iriomote , Ryukyu Is., x.1994, M. T . Kimura leg. ( SEHU) . China: 1♂ (A-type), Mt. Emei , Sichuan, 550 m a.s.l., 18.vii.1992, M.J. Toda leg. ( SEHU) .

Distribution. Ryukyu Is., Taiwan, China ( Shaanxi, Jiangxi, Fujian, Guangdong, Guangxi, Guizhou, Sichuan, Yunnan).

Remarks. This species resembles P. pavriarista in the morphology of the aedeagal sheath and postgonites, but can be distinguished from it by the diagnostic characters.
