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); parvipinne: From the words parvi, meaning short or small, and pinne, fin (Ref. 10294) More on authors: Gilbert & Swain.
Environment: milieu / climate zone / depth range / distribution range

Maturity: Lm ?  range ? - ? cm
Max length : 6.7 cm TL male/unsexed; (Ref. 5723); common length : 4.6 cm TL male/unsexed; (Ref. 12193)
Inhabits clay and sand-bottomed runs and pools of vegetated, spring-fed headwaters and creeks (Ref. 5723, 10294). Feeds on midge larvae, dipteran pupae, caddisfly larvae, dytiscid beetle larvae, and small crayfish (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00236 - 0.01278), 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.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
