 Issued from : K.A. Brodskii in Calanoida of the Far Eastern Seas and Polar Basin of the USSR. Opred. Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.154, Fig.68].

Nota: A characteristic feature of the new species are the form of the thoracic spikes, which are large, slightly converging apically, and the relatively wide segments of P1.

Points of last thoracic segment reaching to the end of first third of genital segment. 2 - Endopodal segment 2 of Md wuith 8 (7 terminal and 1 posterior) setae. 3 - Points of last thoracic segment exceeding the middle of genital segment. Exopodal segment 3 of P1 with external spine 1.30-1.47 longer than external spine of segment 2.
