Type locality: Thailand .

This species is distinguished from the other 2 species in the genitalia by having preanal appendages reaching the fused hump of the apicodorsal setose lobes, and presence of 2 steps in the intersegmental depression between segment IX and segment X. In P.pectinata , new species only 1 step is present, and in P. yitungshana , new species no steps are present. There are significant differences among the 3 species also in the groove and setal wart patterns both on the head and on the thorax. Examination of a male paratype revealed that the species has a setal theca, the alveoli on the basolateral part, present on the first 13 segments of each flagellum, indicating presence of pecten. On the abdomen, a sternal projection (hammer) is present on the posterior margin of segment VI, forming an elongated, robust, rod reaching the segment margin. This sternal projection is reinforced by the ventrad curving internal ridge of the longitudinal suture, possibly giving attachment surface for muscles operating the hammer. The sternal process, especially the ventral surface, is densely covered by closely-set microtrichia.
