Etymology: Erimystax: Greek, eri = aumentative prefix, a lot + Greek, mystax = moustache (Ref. 45335); insignis: From the words eri, an intensifying prefix; stigma, spot; and insignis, meaning remarkable (referring to the distinct pigment pattern) (Ref. 10294) More on authors: Hubbs & Crowe.

Inhabits rocky riffles and runs of clear small to medium rivers (Ref. 86798). Feeds on periphyton and aquatic insect larvae dominated by dipterans (midges and blackflies) and mayflies (Baetidae and Potamanthus) (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00235 - 0.01070), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 2.9 ±0.4 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 (24 of 100) .
