Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); fasciatus: Specific name from a Latin work meaning envelop with bands, referring to the striking bands or saddles on th eupper half of the body.

背的软条 (总数) : 5 - 6; 臀鳍软条: 16 - 20. Diagnosis: Differs from other Noturus elegans species group by the following: anal fin more elongate with modally 18 rays (vs. 16); Nape with boldly contrasting pigment pattern of 3-4 ivory to yellow ellipses; dorsum interrupted by dark chocolate brown saddles (vs. pale blotches not strongly contrasting); adipose fin blotch extending to middle of fin, but nearly always to its edge (vs. blotch in lower half of fin or confined to base); small, dark saddle on ventral edge of caudal peduncle (vs. dark saddle absent from caudal peduncle); adipose fin rather high, intermediate in length and weakly connected to caudal fin (vs. low, long in length, and moderately connected to caudal fin in N. crypticus or moderate in height and length and well connected to caudal fin in N. elegans); diffuse band or crescent-shaped dark blotch at caudal fin base (vs. dark crescent-shaped blotch absent at caudal fin base); modally 36 post Weberian vertebrae (vs. modally 34-35); slender body shape, with body width at pectoral fin origin 21 % or less of SL and shorter than anal fin base length (vs. body width 23% or more of SL and longer than anal fin base length in N. crypticus). Noturus elegans and N. fasciatus differ by 6.6% sequence divergence (uncorrected p) for Cytb and unique genotype distributions for eight allozyme loci: s-AAT-A, FUM-A, GPI-A, sICDH-A, LDH-B, MPI-A, Pep-B, and PGM-A (Ref. 56218).
鉴别: 有别于其他 美石鮰〔Noturus elegans〕 种群藉由跟随: 具有典型地 18个鳍条的臀鳍更多的延长;(vs.16) 大胆地后颈有对比 3-4个象牙制的到黄色的椭圆的有颜色图案; 背面借着深褐色鞍状斑中断;(vs. 灰白的斑块不强烈地对比) 延伸至鳍的中央的脂鳍斑块, 但是几乎总是对它的边缘;(vs. 斑块在鳍的下半部中或局限于基底) 小的, 在尾柄的腹边缘上的黑色鞍状斑块;(vs. 黑色鞍状斑块尾柄没有出现) 脂鳍相当高又介于两者之间长度而且微弱地连接到尾鳍;(vs. 低又長的長, 與一般連接到尾鰭在 N. crypticus 中或中等的在 N. elegans 中的高度與長度與連接到良好的尾鰭) 在尾鰭基底的擴散條紋或新月形的黑色斑塊;(vs. 深色的新月形的斑塊在尾鰭基底不存在) 典型地 36個後 Weberian 脊椎骨;(vs. 典型地 34-35) 細長的體型, 與身體寬度在 SL 與短於臀鰭基底長度的胸鰭起源 21% 以內.(vs. SL 與長度超過臀鰭基底長度的身體寬度 23% 或更多在 N. crypticus 中) 美石鮰〔Noturus elegans〕 與 N. fasciatus 對於八個 allozyme 現場為 Cyt b 與獨特的基因型分布藉著 6.6% 序列分歧 (不改正 p) 不同: s-AAT-一, FUM-一, GPI-一, sICDH-一, LDH-B, MPI-一, 活力-B, 與 PGM-一.(參考文獻 56218)
Collected from riffle habitats with gravel, cobble, rubble, or slate substrate; mean depth of 0.2 meters (0.1 - 0.3 m), and stream width averaged 13.6 meters (range 8 - 25 m); mean current readings from the 3 capture sites ranged from 0.59 - 0.76 meters per second. Riffles are typically occupied during daylight hours when individuals are likely buried within the interstices of gravel. Based on its small adult size (to 72 mm SL), this species probably lives no longer than 2-3 years. Preserved females contain mature oocytes from late May to late July; females are mature at sizes as small as 44 mm SL (Ref. 56218).
采集自急流了栖息地有砾石的, 圆石，碎石或暗蓝灰色底部; 意谓 0.2 公尺的深度 (0.1- 0.3 公尺), 而且水流宽度平均了 13.6 公尺 (范围 8- 25 公尺); 意谓水流阅读从 3个抓取位置范围从 0.59- 0.76 公尺每秒。 当个体是埋藏在或许里面的砾石的空隙的时候，急流典型地在白天的时候被占领。 超过 2-3 年可能建立了在它的小成鱼大小 (to 72 mm SL) ，这种生命不再。 母鱼标本包含成熟的卵母细胞从迟的可以对七月下旬; 雌性是在像 44 mm SL 那样小的大小時成熟.(參考文獻 56218)
