21. Pachygrapsus corrugatus (von Martens, 1872)

– Reported from French Guiana by Corbari et al. (2015: 165–167, from Iles du Salut 2014 Expedition, stn SM04, shoreline, 01/10/2014, MNHN-IU-2014-8309 at http://coldb.mnhn.fr/catalognumber/mnhn/iu/2014-8309). Obviously not Pachygrapsus corrugatus, based on photograph available at MNHN link, but most probably Goniopsis cruentata (re-id. from photo D. Felder, for this study).
