Periclimenes acanthimerus, A.J.Bruce, 2006

Bruce, A. J., 2006, An unusual new Periclimenes (Crustacea, Decapoda, Palaemonidae) from New Caledonia, Zoosystema 28 (3), pp. 703-712 : 712

In P. foveolatus , for example, the distal ends of the exopods are provided with about 14 densely plumose setae, and a well developed arthrobranch with about 12 lamellae is present on the third maxilliped.In these respects Periclimenes acanthimerus n. sp. is generally similar to P. parvispinatus ; P. coriolis is intermediate in its morphology. The sparse setation on the dorsal surface of the scaphocerite appears to be an unusual feature, not previously reported in the Pontoniinae , but its presence in other species could well have been overlooked. Th ese setae appear similar, but more slender, to the spinules that occur on the ventral tubercles of the second pereiopod. The latter may also occur as transverse rows of up to four spinules in the ventral surface of the palm of the chela.
