Diagnosis Original diagnosis by Gibbs (1971: 144): "Small nereids that are generally similar to Namanereis but which lack frontal antennae. Prostomium with two pairs of eyes and two biarticulate palps. Proboscis without paragnaths but with a pair of toothed jaws. Peristomium with three pairs of tentacular cirri but not parapodia. Parapodia are sesquiramous throughout, each lacking a notopodial lobe but with a notopodial aciculum. Superior neuropodial setae are spinigerous, the rest being falcigerous. At maturity, parapodia become biramous with the development of capillary setae." [details]
Etymology Not stated. The name of the genus is composed by the prefix of Greek origin crypto-, meaning 'hidden', 'invisible', or 'secret', followed the name of the genus Nereis Linnaeus, 1758. [details]
