I. Marin, 9 Sept. 2010. Short diagnosis. Carapace (Fig. 2 a, b) swollen, smooth, with well-developed antennal, hepatic and supraorbital teeth, with supraocular teeth; hepatic spine similar to antennal. Rostrum (Fig. 2 a) horizontal, compressed, slightly overreaching scaphocerite, with tip slightly turned upward, with deep ventral part. Rostral formula 2+6–7/4 (Fig. 2 a, b). Eyes (Fig. 2 a) well developed, with semispherical cornea; eyestalk subcylindrical, without a knob on it medial anterodorsal margin; with accessory pigment spot. Pereiopod I slender; palm about twice longer than wide, subcylindrical, fingers simple, slender, with acute tips and straight cutting edges. Pereiopod II similar in size and shape (Figs. 1, 2 e); with slender segments; palm subcylindrical, about 3 times as long as maximal width; fingers simple, slender and straight, about 4 times as long as wide, with acute tips and straight cutting edges (Fig. 2 f). Pereiopod III (Fig. 2 g) relatively slender; merus about 8 times as long as wide; carpus about 4 times as long as wide, with projected distodorsal margin; propodus about 10 times as long as wide, with ventral margin bearing 3 single and 4 paired ventral spines and a pair of distoventral spines; dactylus (Fig. 2 h) moderately robust, about 5 times as long as maximum width, tapering distally, with stout curved unguis. Pereiopods III–V similar. Coloration. Body and appendages generally translucent covered by irregular brown, white and red dots (Fig. 3). Habitat. In Nhatrang Bay, the species was found in association with unidentified antipatharians (black corals), gorgonians and alcyonarians Dendronephthya sp. (Nephtheidae). Shrimps inhabit hosts in groups of 20–30 individuals. The single ovigerous female from GBR of Australia was found in association with bushy antipatharian (Octocorallia, Antipatharia) (Marin & Caley, 2011). Known in associations with antipatharians, gorgonians and hydroids (Chace & Bruce, 1993). Distribution. Eastern Africa to Maldive Islands, South China Sea, Japan, Indonesia, Queensland of Australia and New Caledonia (Chace & Bruce, 1993; Bruce & Coombes, 1995; Li & Bruce, 2006; Marin, 2012; Okuno & Chan, 2012).
