Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); marhabatiensis: The specific name is derived from its type locality, the town of Marhabatio (P’urepecha word of Maravatío). The P’urepecha word Marhabatio means beautiful thing or place.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 7 - 8; Anal spines: 1 - 2; Anal soft rays: 6 - 7. Can be identified by having the following combination of characters: pelvic fin with 7 branched rays, rarely 8; scales in transverse series 9, rarely 8; and a dark, narrow lateral stripe runs from around the pectoral fin to the origin of the caudal peduncle (Ref. 84762).

Occurs in a spring that is highly degraded and used for recreation. The spring has growing aquatic plants of the genus Ceratophyllum and substrate composed mainly of sand and gravel with many boulders at athe bottom of the pool and mud in the stream. Other fish species found in the spring include the native goodeids Girardinichthys multiradiatus and Goodea atripinnis, and the introduced cichlid Oreochromis sp. and the poeciliids Poecilia reticulata and Heterandria bimaculata (Ref. 84762).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.9 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
