Robertsella meridionalis - Poupin & Corbari, 2016, in press, Guadeloupe (first record), Karubenthos II 2015, field det. J. Poupin, st. CP4524, 10 June 2015, 16°30.17'N, 61°42.4'W, 550-500 m, MNHN-IU-2013-18803.
Comment: Photographs were determined, with the help of D. Felder and M. Tavares (pers. com.). The determination is based on characters presented in Tavares & Gouvêa (2013). Robertsella meridionalis Tavares & Gouvêa, 2013 and R. mystica Guinot, 1969c are two very close species that can be easily confused. Although the specimen photographed matches very well with black and white photograph of R. mystica in Guinot (1969c, pl. V, fig. 1) it is attributed herein to R. meridionalis based on: a) aspect of left P2, being more pilose on carpus, propod and dactyl than in R. mystica (compare fig. 2D-H and 4B-D in Tavares & Gouvêa, 2013); b) aspect of P5 being ventrally tuberculate on its ventral margin (instead of almost smooth in R. mystica). Others characters useful to separate the two species in Tavares & Gouvêa (2013) cannot be verified on the photographs and must be checked with the specimen. This is a first record for Guadeloupe and a geographic extension range of R. meridionalis from Brazil (Santa Catarina, 27°S) to Lesser Antilles.
