Family Nototanaidae Sieg, 1976 and Typhlotanaidae Sieg, 1984

Abstract

The deep-water tanaidaceans of the family Typhlotanaidae Sieg, 1984 were examined. In the material seven species were recognized. Three of them Typhlotanais compactus Kudinova-Pasternak, 1966, Torquella angularis (Kudinova-Pasternak, 1966), and Peraeospinosus magnificus (Kudinova-Pasternak, 1970) were already known to science. Four others were undescribed, but because only one of them, Larsenotanais kamchatikus n. sp, was represented by more than one specimen, is described in this paper. Additionally, redescriptions of the poorly known T. angularis and T. compactus, supplement this paper.
