Cumella portoricensis sp. nov. resembles C. croixensis sp. nov. from Puerto Rico having one denticle on the carapace and serrate ventral margin of carapace, pereopod 2 with dactylus with two setae on medial margin, short uropods. It differs from C. croixensis in: 1) ocular lobe with five lenses in C. portoricensis vs. six in C. croixensis; 2) dorsal denticle on frontal lobe vs. on carapace immediately behind frontal lobe (only in female); 3) smooth anterior margin of pseudorostrum vs. serrate; 4) pereopod 1 with setae on medial margin of carpus to dactylus vs. basis to dactylus; 5) pereopod 2 without setae on on medial margin of basis and merus, one on medial margin of carpus and two on medial margin of dactylus vs. simple setae on medial margin of basis and merus and two plumose ones on outer margin of carpus; 6) uropodal peduncle with one seta on outer margin and two on medial one vs. without setae.</description><description>Published as part of Petrescu, Iorgu, Chatterjee, Tapas & Schizas, Nikolaos V., 2016, New species and new records of Cumacea (Crustacea: Peracarida: Cumacea) from mesophotic reefs of Puerto Rico and U.
