ZMMU Op-402, 1 specimen (4.8 mm in length, 1 mm in width, live), same locality, collected by T.A. Korshunova, A.V. Martynov, 0 3.08.2012. Type locality. Dalnie Zelentsy, Barents Sea. Etymology. This species is named in honour of the scientist and marine biologist Ninel Panteleeva (Murmansk Marine Biological Institute), who for a long time lived in the Dalnie Zelentsy settlement, close to the type locality of this species. Ninel also generously helped us with the field work at Dalnie Zelentsy. Description of adults. External morphology. The length of the holotype is 6 mm and width 1.2 mm (Fig. 1A– B). The length of more than one hundred observed living mature specimens ranged from 4 to 6 mm, the width ranged from 0.6 to 1.2 mm. The body is narrow. The rhinophores are similar in size to the oral tentacles, smooth. The cerata are relatively long, thin, finger-shaped. Ceratal formula of the holotype: right (2,2,2; anus, 2,2,1) left (2,3,3; 3,2,1). The foot is narrow, anteriorly rounded, no foot corners. Colour. The ground colour is whitish. The digestive branches in the cerata are pale brownish to pinkish. A few small opaque white spots are scattered at the ceratal tops. There are no white spots ... |
