Material examined. – 1 female, Wotou, Guangdong, intertidal, 23 Dec.1980 ; 1 male, 4 ovig females, CN 92 C-1120, Meixia, Lingao, Hainan Is., intertidal, coll. X. Li, 8 Apr.1992 ; 1 juv., CN 92 C-045, Xiaodonghai, Sanya, Hainan Is., 18 Mar.1992 .

Diagnosis. – Rostrum usually nearly horizontal with margins tapering to sharp apex in anterior half, with 2-3 + 7-13/3-5 teeth. Antennule with distolateral spine of basal antennular segment not over-reaching adjacent convex distal margin of segment, dorsal antennular flagellum with free part of short ramus 3 times as long as fused part. Mandible with well developed 3-segmented palp.

Distribution. – India, Burma, Taiwan to South East Asia, northern Australia, from the Kimberleys, Western Australia, to Moreton Bay, Queensland, Japan and Vladivostok, Russia; littoral marine waters.

Remarks. – This species is morphologically very close to P. pacificus . The size and number of the rostral teeth is variable and overlapping between the two species. The two species can only be distinguished by the shape of the rostrum and the the basal antennular segment.
