Narrowteuthis nesisi, a new genus and new species of the squid family Neoteuthidae (Mollusca: Cephalopoda)

摘要

A new neoteuthid genus and species, Narrowteuthis nesisi, is described on the basis of two specimens with the following characters that are unique within the family: laterally compressed proximal manal suckers, short tentacular clubs relative to mantle length, and smooth sucker rings on arm suckers. It is also the only neoteuthid in which the proximal and distal manus regions of the club are approximately equal in length.
