Diagnosis

This species is similar to P. latipenis in the male terminalia, it can be distinguished from the latter species by the paramere; in the new species, paramere black and bifurcated distally, the posterior branch strongly expanded submedially, with one acute projection apically ( Fig. 4C ) (in P. latupenis : paramere neither black nor expanded in posterior branch; as in Chen et al. 2005, fig. 7C).

Etymology

Toponym, according to the locality of type specimens in the language of the Dai community in Yunnan, China.
