Ictaluridae (North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); crypticus: Name from the Greek stem 'kryptos', meaning hidden or secret, referring to this species' secretive habits, and for having kept its identity in secret for so long.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 6; Rayons mous anaux: 15 - 17. Diagnosis: Distinguished from other members of the Noturus elegans species group by having: modally 16 anal rays (vs. 18 in Noturus fasciatus); modally 8 pelvic rays (vs. 9); 2-10 medium-large sized melanophores on the cheek (vs. large melanophores absent on cheek); adipose fin band extending only to base or half-way up fin (vs. extending half-way up to edge of fin in fasciatus); adipose and caudal fins distinctly joined at their juncture (vs. weakly connected in fasciatus); three evenly spaced pale and dark bands in caudal fin (vs. caudal fin bands usually two and unevenly spaced); robust body shape, with body width at pectoral fin origin 23% or more of SL and greater than anal fin base length (vs. slender body shape, with body width at pectoral fin origin 22% or less of SL and less than anal fin base length). There is an absence of shared alleles for eight allozyme loci (mAAT-A, sACOHA, GPI-B, LDH-B, sMDHP-A, Pep-b, Pep-D, and PGM-A) distinguishes crypticus and fasciatus, which also differ by 5% Cytb sequence divergence. Similarly, both share no alleles at eight allozyme loci (mAAT-A, sAATA-A, sACOH-A, FUM-A, GPI-A, GPI-b, LDH-B, sMDHP-A, and Pep-D) and are 6.3% divergent for Cytb (Ref. 56218).
Migratory behaviour is undetermined (Ref. 126106).
