Range and Identity
Allohistium maydeni is accepted in the modern catalog, while its original description uses Etheostoma maydeni. It occurs in large Cumberland tributaries below Cumberland Falls in Tennessee and Kentucky. Records attributed broadly to the former Ashy Darter complex require careful reassessment.
Habitat and Behavior
The elongated, pointed snout and patterned sides belong to the broader complex. Red pigmentation on the outer lips helps distinguish this species. Diagnostic fin-ray and scale counts also contribute, so a common-name impression alone is less reliable than a complete set of features.
Food and Life History
The descriptive upper reference is eight centimeters standard length, excluding the tail. The checked treatment does not establish a detailed diet or a range-wide spawning calendar. Those biological gaps are not filled with measurements or behavior assigned to another member of the complex.
Field Note
A clear view of the lips can be useful, but keep it with a whole-body view and locality. Identification depends on a combination of features.
