Incertae sedis. Anonyx anivae Gurjanova, 1962 (gnathopod 1 propodus margins subparallel, antenna 2 without brush setae, mouthparts unknown); A. derjugini Gurjanova, 1962 (accessory flagellum not forming a cap); Anonyx lebedi Gurjanova, 1962 (gnathopod 1 ischium long); Anonyx magnus Gurjanova, 1962 (gnathopod 1 very weakly subchelate and no constriction on uropod 2 inner ramus).
Removals. Anonyx lebedi Gurjanova, 1962 to Tmetonyx. Gnathopod 1 with long ischium and propodus with subparallel margins.
Diagnostic description. Antenna 1 peduncle article 1 without anterodistal lobe; accessory flagellum forming cap covering callynophore. Antenna 2 with brush setae. Mandible molar setose with vestigial triturating surface. Maxilla 1 outer plate a well developed 7/4 crown. Maxilla 2 inner plate slightly to significantly shorter than outer plate. Gnathopod 1 subchelate (occasionally parachelate); coxa 1 large, about as long as coxa 2, subrectangular with straight or concave anterior margin; ischium short (length less than 2 × breadth); carpus short (length 1 to 2 × breadth) or long; propodus margins slightly tapering distally. Uropod 2 inner ramus constricted (weak to strong). Telson moderately to deeply cleft.
Remarks. Anonyx appears to be most similar to Onisimus. Both genera have a subchelate first gnathopod with a short carpus. However Anonyx has bush setae on antenna 2 (absent in Onisimus) and the molar is a strong setose tongue (a reduced column with triturating surface in Onisimus). Both genera are scavengers with wide-spread distributions in arctic/boreal regions.
Anonyx is also similar to Tmetonyx. They differ in the accessory flagellum cap (absent in Tmetonyx), the mandibular molar (setose with a reduced column with convex triturating surface in Tmetonyx), the ischium of gnathopod 1 (long in Tmetonyx), and the margins of the propodus (subparallel in Tmetonyx).
