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.
