Type material

Pallenoides amazonicus Stock, 1975 . Holotype: NL ZMA.PYC.P.1356 (not examined). Type locality: off Pará State, Brazil.

Material examined

MARTINIQUE • 1 ♀; SW of Vétiver ; 14°37.6ʹ N, 61°08.6ʹ W; depth 66 m; 7 Oct. 2016; st. AD612; MNHN-IU-2016-866/ MK411177 .

Remarks

This unique specimen is very close to Stock (1975a) ’s original description; however, we note a few discripencies that make this identification unsure, i.e., the shorter auxillary claws of the Martinique specimen (about half as long as in the holotype) and its conspicuous pointy tubercle on the dorsal surface of the chelifores. In the absence of a CO1 barcode sequence for P. amazonicus , we refrain from describing this species as new.

A single specimen was collected on the Caribbean coast, off Vévier.

Distribution

Pallenoides amazonicus is known from Brazil, with one juvenile that has been considered as a possible P. amazonicus collected in South Africa ( Arnaud & Child 1988), though this record seems very doubtful. If confirmed, the present record would be the first one for the Caribbean.

Depth range

Pallenoides amazonicus is known to dwell between 17 and 136 m. The present specimen was sampled at 66 m.
