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.

背的软条 (总数) : 6; 臀鳍软条: 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).
鉴别: 与 美石鮰〔Noturus elegans〕 种群的其他成员借着具有区分了: 典型地 16个臀鳍鳍条;(vs.18 在 Noturus fasciatus 中) 典型地 8个腹鳍鳍条;(vs.9) 在颊部上的 2-10个中等- 巨大的体型黑色素细胞;(vs. 大的黑色素细胞在颊上不存在) 脂鳍条纹只有对基底延伸或一半的-在鳍上面的方法;(vs. 延伸鳍的一半-方法向上到边缘在 fasciatus 中) 脂鳍与尾鳍明显地在他们的接合结合;(vs. 弱的在 fasciatus 連接) 三均勻地有間隔的灰白與在尾鰭的深色條紋;(vs. 尾鰭條紋通常二與不平坦地有間隔的) 結實的體型, 藉由身體寬度在 SL 與大於臀鰭基底長度的胸鰭起源 23% 或更多.(vs. 細長的體型, 藉由身體寬度在 SL 的胸鰭起源 22% 以內而且少於臀鰭基底長度) 有一缺乏分享等位基因為八個 allozyme 現場 (mAAT-一, sACOHA, GPI-B, LDH-B, sMDHP-一, 活力-b, 活力-D, 與 PGM-一) 區別 crypticus 與 fasciatus, 也藉由 5% Cytb 序列分歧不同。 同樣地, 兩者的分享沒有等位基因在八個 allozyme 現場 (mAAT-一, sAATA-一, sACOH-一, FUM-一, GPI-一, GPI-b, LDH-B, sMDHP-一, 與活力-D) 而且是 Cytb 的 6.3% 發散的.(參考文獻 56218)
