7138A001EF37EB2B6FC3B1A89513CEA8.taxon	etymology	Etymology. Named after the Caribbean Sea.	en	Petrescu, Iorgu, Chatterjee, Tapas, Schizas, Nikolaos V. (2012): New genus and new species of Cumacea (Crustacea: Peracarida) from the mesophotic coral ecosystem of SW Puerto Rico, Caribbean Sea. Zootaxa 3476: 55-61, DOI: 10.5281/zenodo.211298
7138A001EF37EB2B6FC3B1A89513CEA8.taxon	discussion	Remarks. The new genus and species resembles three other genera within the family Nannastacidae: Almyracuma Jones & Burbanck (1959), Claudicuma Roccatagliata, 1981, both from American waters (Jones & Burbanck, 1959; Roccatagliata, 1981) and Picrocuma Hale, 1945 from Australia (Hale, 1945). The shared morphological characters of these genera are the carapace without any antennal notch and the pediform aspect of maxilliped 3. Cumellana caribbica gen. et sp. nov. can be distinguished from the three genera by a combination of characters: labium with a terminal forked seta, propodus of maxilliped 3 longest article of appendage, dactylus of pereopod 2 with short terminal setae, uropod peduncle shorter than uropod rami. There are some similarities between the new genus Cumellana and four species of the genus Cumella (C. clavicauda Calman (1911), C. coralicola Bäcescu (1971), C. murariui Petrescu (2002) and C. radui Petrescu & Iliffe (1992 )): carapace without evident antennal notch, uropodal peduncle shorter than last pleonite. However, the genus Cumellana can be differentiated from Cumella by the longer antennules, maxilliped 3 with shorter basis and longer propodus, and shorter terminal setae of pereopod 2.	en	Petrescu, Iorgu, Chatterjee, Tapas, Schizas, Nikolaos V.
