Discussion: Formerly included intercastellanus, interpositus (= vestitus) and lullulae (see G. G. George, 1979). Flannery et al. (1987) first suggested that the southern races may prove to be specifically distinct; Flannery (1990) did not adopt this course, but Flannery (1994 a) separated them. Two undescribed species, related to P. orientalis, occur on Mt. Karimui. The species needs revision; Flannery (1995 b) provisionally recognized only Solomons/Bismarcks breviceps as a subspecies.
