MARTÍNEZ ARBIZU, PEDRO 1997 12 22. A new genus of cyclopinid copepods (Crustacea), with a redescription of Smirnovipina barentsiana comb. nov. (SMIRNOV, 1931). – Sarsia 82:313-323. Bergen. ISSN 0036-4827. A new genus, Smirnovipina gen. nov., is proposed to accommodate the cyclopinid copepod Cyclopina barentsiana. The species is redescribed on the basis of new material from hyperbenthic layers in the northern Barents Sea (Arctic Ocean). Smirnovipina gen. nov. is the only member of the Cyclopoida which has a rudimentary 1-segmented antennary exopod as an adult. The new genus is the sistergroup of a taxon comprising Cyclopinoides LINDBERG, 1953 and Ginesia JAUME & BOXSHALL, 1997. It shares with these taxa the absence of coxal inner seta on leg 5, structure of the inner basal spine on leg 1, modification of the inner seta on the first endopod segment of leg 4 and fusion of ancestral female antennulary segments XII-XIV.
