Family: Typhlotanaidae Sieg, 1976

Diagnosis (new): Blind. Antennule three-articled. Antenna six-articled. Molar process wide. Maxilliped distal endites with two tubercles. Cheliped without side piece. Pereopods 1–3 with coxa, pereopods 4–6 clinging type, without coxa, with prickly tubercles on carpus (except Obesutanais and Hamatipeda ), dactylus and unguis not fused (if fused than modified to hook), pereopod-6 propodus with three terminal setae distally. Uropod rami one- or two-articled. Marsupium formed from four pairs of oostegites.

Male (where known): swimming type.

Genera included: Typhlotanais G.O. Sars, 1882 sensu stricto; Typhlotanais sensu lato; Peraeospinosus Sieg, 1986 ; Typhlotanaoides Sieg, 1983 ; Obesutanais Larsen et al. 2006 ; Hamatipeda n. gen.; Larsenotanais n. gen.; Pulcherella n. gen.; Torquella n. gen.; Typhlamia n. gen.

Remarks: Two species, Typhlotanais dubius and T. gruzovi , do not have the clinging form of pereopods 4–6. T. dubius almost certainly belongs in Pseudoparatanais , while T. gruzovi may belong to Paratyphlotanais or a similar genus (Bird, pers. comm.). As this material is not available for study the problem cannot be resolved for a while, but it is quite probable that these species cannot be included within the Typhlotanaidae as defined here.
