Material examined. – 1 male, Luhuitou, Sanya, Hainan Is. , coll. J. Y. Liu, 21 Nov.1990 ; 1 ovig female, CN 92 C-1449, Xincun Harbour, Hainan Is. , 1-3m, with living corals, coll. X. Li & V. Neumann, 26 Mar.1992 ; 6 males, 1 female, 9 ovig females ( IOCAS) , 1 male, 1 ovig female ( ZRC) , 1 male, 1 ovig female (SI), CN 92 C-187B, Xincun Harbour, Hainan Is. , 1-3m, with living corals, coll. X. Li & V. Neumann, 27 Mar.1992 ; 1 male, CN 92 C-1412C, Lanmai, Lingao, Hainan Is. , coll. X. Li, 9 Apr.1992 .

Distribution. – Common and widely distributed in the Indo-West Pacific region, except for Red Sea and NW Indian Ocean. Free living, preferring coral reefs.

Remarks. – Duris & Bruce (1995) separated Palaemon petitthouarsii Audouin, 1826 and Periclimenes petitthouarsii var. spinifera De Man, 1902 from genus Periclimenes , and assigned them to a new genus Periclimenella , on the basis of their characteristic first and second pereiopods. The presence of a sound-producing mechanism in the chela of the second pereiopods was used to distinguish Periclimenaeus from Exoclimenella and the rest of the pontoniine genera (see Bruce, 1988). We follow Duris & Bruce (1995) here.
