Distribution & Ecology: Sala y Gomez; Marquesas (Nuku Hiva) - Marine; Deep (391-408 m); ?Hard bottom.

Regional Records: EASTER ISLAND - Plesionika (Plesionika) ensis - Burukovsky, 1990: 204 (Seamounts Sala y Gòmez and south-western part of Nazca ridge, 24°58'-25°33' S - 86°34'-97°26' W; 300-800 m). - Parin et al., 1997: 162, tab. 3 (List of Decapoda for the Nazca and Sala y Gòmez submarine ridges). - Remark - This is a sibling species of P. reflexa Chace, 1985 present in French Polynesia. Morphological differences between these two species need to be clarified (see Chan & Crosnier, 1997: 194). Comparison of specimens from Sala y Gòmez and French Polynesian Islands would be interesting. - FRENCH POLYNESIA - Plesionika ensis - Unpublished specimen, MNHN, det. A. Crosnier, MUSORSTOM 9, st. CP1169, Nuku Hiva, 391-408). - Confusion has been often observed between this species and sibling P. reflexa. Presence of P. ensis in Polynesia should thus be confirmed by study of more specimens.

Depth distribution: 391 - 408 m
