Diagnosis.

Most similar to the new species P. kabaki sp. nov., especially in the distal part of the telopodite with a large, serrated lamella, differing by the short trapezoid lamella (vs larger rectangular one).

Descriptive notes.

Holotype 45 mm long, 2.9 mm wide, 52 podous + apodous PTs, general colour brown.

Male sexual characters.

Leg-pair 7 with two coxal processes ( Wang and Zhang 1993; Wang 1996). Gonopods (based on Wang and Zhang 1993: figs 24-26). Parallel, each gonopod with two asymmetrical, clavate prefemoroidal processes, with (pf1) larger and more setose than (pf2), the latter distally folded; one large broad and long coxal process (b), reaching the distal part of the telopodite and apically projecting in a pointed tip. Telopodite (T) with a stout stem, distally expanding into a lateral lamella with a serrated margin, separated by a deep notch from a median branch. Latter presenting a blunt subapical projection, and a longer twisted process, curved and bifurcating at the tip, with the opening of the solenomere (s) and parasolenomere (ps).
