‘ plicatus ’ group

Diagnosis: Pereonites 1–3 with minute transversal ridges.

Species included: Typhlotanais longimanus, Dollfus, 1897 ; Typhlotanais plicatus Kudinova-Pasternak, 1993 ,? T. variabilis Hansen 1913

Remarks: Typhlotanais longimanus and T. plicatus share the unique character of a corrugated cuticle on the first three pereonites. The third species, T. variabilis , has this character weakly developed (G. Bird. pers. obs.). The material obtained for this study was the poorly preserved type material of T. longimanus and T. variabilis , and one manca of T. plicatus . This slender material precluded dissecting any specimen and establishing a reliable set of characters for this morpho-group. Nevertheless, the corrugated pereonites 1–3 is a feature specific enough for provisionally distinguishing the ‘ plicatus ’ morpho-group.
