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).

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 8.4 cm TL male/unsexed; (Ref. 5723); common length : 7.0 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).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00537 (0.00235 - 0.01227), b=3.14 (2.94 - 3.34), in cm total length, 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.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
