A new species of Cumella (Cumacea, Nannastacidae) from Argentina, and a partial redescription of Cumella vicina Zimmer, 1944

A new nannastacid cumacean, Cumella biformis, is described from the Argentinean continental shelf. C. biformis is readily distinguished from the other known species of Cumella by having: (1) a short, upturned pseudorostrum lacking projecting siphons and (2) uropods with distal spines fused to the ra...
