Material examined

Loyalty Islands: MUSORSTOM 6, stn DW431, 20 ° 22.259N, 166 ° 10.009E, 21 m, 18 February 1989, 1 „ (MNHN-Na 14916) .

Remarks

This common and widely distributed coral associate, one of the first pontoniine shrimps to be described, has not been previously reported from Loyalty Islands. The specimen has a rostral dentition of 1(?)+6/2, and lacks both second pereiopods. The second maxilliped has the characteristic diagnostic distal segments and the third maxilliped has a well-developed arthrobranch. The ambulatory dactyls are also typical of this species. The present depth record may represent the maximum depth from which this species has so far been recorded.

Distribution

Type locality: Tongatapu Island, Tonga. Also known from the Red Sea, Egypt, Israel, Saudi Arabia, Sudan, Ethiopia ( Eritrea), Kenya, Zanzibar, Tanzania, Comoro Islands, Madagascar, Seychelles, Maldives, Singapore, Vietnam, Japan, Indonesia, Australia (Northern Territory, Queensland), Coral Sea, Solomon Islands, Loyalty Islands , Tonga, and Samoan Islands .
