Material. 2 males, syntypes, SMF 8526, Indonesia, Ambon, coll. J. Brock.
Diagnosis. Medium-sized pontoniine shrimp. Carapace bearing supraorbital, antennal and hepatic teeth; antennal tooth larger than hepatic (Fig. 1 A–C). Rostral formula 1+6–7/2–3, with the most proximal dorsal tooth situated slightly behind the level of hepatic tooth. Scaphocerite of antenna significantly overreaching distal margin of blade (Fig. 1 D). Second pereiopod similar in size and shape, with robust segments (Fig. 2 A, B); merus with strong sharp distoventral tooth (Fig. 2 F); carpus with strong disto-lateral and disto-ventral teeth (Fig. 2 C–E), propodus about 4 times as long as wide; fingers with small triangular teeth situated in proximal half. Third pereiopod (Fig. 1 E) with robust segments, not overreaching the level of distal margin of scaphocerite, propodus without ventral spines, with a pair of small disto-ventral spines hidden by tuft of simple setae; dactylus simple (Fig. 1 F).
Remarks. The genus Cuapetes consists of several different Indo-Pacific groups of species mainly differing by form of rostrum, form of chelipeds and ambulatory pereiopods – “ nilandensis ” group (C. nilandensis (type species of the genus)), “ grandis ” group (C. grandis (Stimpson, 1860), C. tenuipes (Borradaile, 1989), C. kolumadulensis (Borradaile, 1915), C. platycheles (Holthuis, 1952), C. lacertae (Bruce, 1992), C. agag (Kemp, 1922)), C. darwiniensis (Bruce, 1987) and C. ensifrons (Dana, 1852)), “ seychellensis ” (C. seychellensis (Borradaile, 1915), C. johnsoni (Bruce, 1987) and, possibly, C. akiensis Kubo, (1936)) and “ elegans ” group of species (C. elegans (Paulson, 1875), C. amymone (De Man, 1902), C. longirostris (Borradaile, 1915), C. andamanensis (Kemp, 1922), C. anacanthus (Bruce, 1988), C. demani (Kemp, 1915), C. digitalis (Kemp, 1922) and C. suvadiensis (Borradaile, 1915)). Coral-associated Cuapetes kororensis (Bruce, 1977) probably should be separated into a new genus. Cuapetes amymone refers to “ elegans ” group and can be clearly separated from other species by the absence of ventral spines on propodus of ambulatory pereiopods.
Distribution. The species occurs in shallow water of the tropical Western Pacific from Nicobar Islands and Singapore to New Caledonia.
