Diagnosis. – Rostrum with 2 + 3-5 + 1-3/10-12 teeth, excluding epigastric tooth on carapace. Carapace with branchiostegal spine removed from margin by about length of spine. Mandible with well developed 2-segmented palp. First pereiopod with fingers distinctly longer than palm, palm subequal or slightly longer than carpus. Second pereiopod with fingers 1.5 times as long as palm, palm distinctly longer than carpus. Third pereiopod with propodus less than three times as long as dactyl. Third abdominal somite with dorsal profile nearly subrectangular, 5th abdominal pleuron with small acute tooth posteroventral tooth. Posterior margin of telson acutely triangular, inner pair of posterior marginal setae slender, with setulose.

Distribution. – Maldive Islands, northeastern India, Andaman Islands, Mergui Archipelago, Indonesian, China, New Caledonia.

Remarks. – See Remarks under Urocaridella antonbruunii . The collection depth records of this species were from about 3.7 m ( Kemp, 1922) to 125 m ( Bruce, 1990a), the material collected from northern South China Sea is from 22 to 79.5 m depth also shows it has a wide bathymetric range species, as well as being a common species in this area.
