Bathypalaemonetes brevirostris — Cleva, 2001: 773 , figs. 7, 8; 2004: 506, fig. 6f.

Material examined. Philippines, Panglao I., stn. CP2343, 9°27.4’N – 123°49.4’E, 273–302 m, sa ndy/muddy substrate, 23 May 2005: 1 ovig. female 9.9 mm.

Remarks. Bathypalaemonetes brevirostris has been well illustrated by Bruce (1986) and Cleva (2001). Dorsal border of the specimen’s rostrum with ten mobile spines (one situated on the carapace proper), plus four–five fixed spines on the distal part; ventral border with six fixed teeth. RL/CL ratio about 0.75.

Colouration. General colouration of the carapace pink-reddish, with six relatively well defined longitudinal white bands; rostrum whitish, with lateral carina pink-reddish; abdomen pink-reddish with somewhat seven transversal white bands on the four first pleura; telson and caudal fans pink-reddish; antennular peduncle and flagella, antennal basis and carpocerite reddish; antennal flagella whitish; all pereopods pink-reddish, the colouration becoming clearer from the basal to the distal articles: ischio-merus reddish, propodus and dactyls rather pinkish, merus to chela of large P2 pinkish.

Though the colouration seems to present some variations (see Cleva 2004, fig. 6f and description by Bruce, 1986: 264), the reddish and white banded pattern appears to be characteristic.

Distribution. Northwest Australia, 306–308m; New Caledonia, 315–410m; Indonesia, 315–348m; Taiwan, 221– 254 m. The specimen, collected between 273–302 m, represents the first record for the Philippines.
