Bathypalaemonetes pilosipes – Cleva, 2001: 776 , Fig. 9.

Material examined. – 1 female 10.5 mm ( NTOU), “ TAIWAN 2001”, R. V. “OCEAN RESEARCHER 1”, st. CD 139, 22 10.73’ N-120 14.1’E, 852- 718 m, 23 Nov.2001 .

Remarks. – This well-preserved specimen fits the previous descriptions. The rostrum is just a little longer than the carapace and overreaches the tip of the scaphocerite; it bears 11 small articulated spines proximally on its dorsal border and five fixed teeth ventrally. Some small differences have been noticed compared to the previously studied specimens: propodus of the major P2 1.10 times carapace length (versus as long as or a little shorter) and tubercles on the fingers more individualized and less blunted.

Coloration. – Cephalothorax orange- to red-brownish (rostrum); abdomen, telson, pleopods, caudal fans pink to reddish; pereiopods pinkish to reddish (major P2 pinkish, minor P2 more or less translucent) ( Fig. 6g ). Some differences can be seen from the coloration described by Bruce (1986: 264).

Distribution. – B. pilosipes is known from north west Australia (390-504 m), New Caledonia (535-560 m), Philippines (410 m), and Japan (350 m). This is the first record for Taiwan and significantly extends the bathymetric range of the species (718-852 m).
