Remarks. The distinctly trilobate rostrum immediately distinguishes P. h e t e ro c h ro u s from two congeners, P. militaris   and P. scabriculus   .

Yang (1983) and Yang & Xu (1994) recorded P. militaris   from the Xisha and Nansha Islands, China. However, the illustrated specimens seem referable to P. heterochrous   on the basis of the characteristic shape of the rostrum. Garth et al. (1987) recorded P. heterochrous   as an undescribed species from Enewetak Atoll, Marshall Islands.

Distribution. Nansha and Xisha Islands in China, Ryukyu Islands, Mariana Islands, Marshall Islands, Chesterfield Islands; subtidal to 23 m; occurring in crevices in dead coral rubble, dead branching coral, and on the base of living coral ( Yang 1983; Kropp 1984; Haig 1987; Yang & Xu 1994; Osawa 1998 c). The specimens examined from New Caledonia and the Loyalty Islands were collected at the depths of 1– 30 m.
