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).
Eponymy: José ‘Pepe’ Lugo Guajardo has acted as a guide for many scientists studying the fauna of Mexico’s Cuatro Cienegas Basin. He also has a reptile named after him. (Ref. 128868), visit book page.

Grootte / Gewicht / Leeftijd
Maturiteit: Lm ?  range ? - ? cm
Max length : 3.5 cm SL mannelijk / geslacht onbekend; (Ref. 26684); 3.8 cm SL (female)
Dorsale stekels (totaal) : 8 - 11; Dorsale zachte stralen (totaal) : 9 - 11; Anale zachte stralen: 6 - 8; Wervels: 36 - 38. Presence of seven paris of branchiostegal rays; nuptial males have a blue throat; subdued body and fin markings; absence of bright or dark green coloration on the flanks; pectoral-fin base without scales.
Body shape (shape guide): elongated.
Adults most often occupy open (not vegetated) although complex bottoms comprised of gravel to cobble-sized fragments of tufa and tufa stromatolites. This substrate is formed largely by calcareous material accreting through physical and biological precipitation of calcium salts as well as by transport of fragmented tufa from upstream that deposits to form armored bars where channels widen abruptly.
