Etymology: Etheostoma: Greek, etheo = to strain + Greek, stoma = mouth; Rafinesque said "various mouths", but Jordan and Evermann suggest the name might have been intended as "Heterostoma (Ref. 45335); rufilineatum: From the words ruf, meaning red, and lineatum, lined (Ref. 10294).
Environment / Climate / Range
Freshwater; benthopelagic. Temperate, preferred ?; 38°N - 34°N
North America: known only from Cumberland (below Big South Fork) and Tennessee River drainages in Virginia, Kentucky, North Carolina, Tennessee, Georgia, Alabama and Mississippi in the USA.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.4 cm TL male/unsexed; (Ref. 5723); common length : 6.9 cm TL male/unsexed; (Ref. 12193)
Inhabit clear, fast rocky riffles of creeks and small to medium rivers (Ref. 5723); also found in streams (Ref. 10294). Adults feed on midge and blackfly larvae, with baetid and heptageniid mayfly nymphs, hydropsychid and hydroptilid caddis larvae, and water mites (Ref. 10294). Eggs are found buried in the substrate (Ref. 7043).

Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00513 (0.00205 - 0.01282), b=3.14 (2.92 - 3.36), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (19 of 100) .
