Comments: Type locality, La Luz Spring (lower Lerma), Zamora, Michoacán, CPUM 1509 (holotype of Zoogoneticus purhepechus, 3.412 cm SL, adult male). It is widely distributed in different drainages along the occidental part of Central Mexico, in the last 5 years, a reduction in its distribution of almost 75% of the historical occurrence points has been observed. The most common alterations reported in the localities where the species has disappeared are the introduction of exotic species, water pollution and desiccation (Ref. 83562). Status of threat: This species should be considered as in danger of extinction, following the criteria and categories of the MER-Aii,Bi,Ci,Di (SEMARNAT 2002) and the International Union for the Conservation of Nature and Natural Resources IUCN A,1a,c,e (83562).

Description synthétique Clés d'identification | Morphologie | Morphométrie

Rayons mous dorsaux (Total) : 13 - 14; Rayons mous anaux: 13 - 14. This species differs from its sister species Zoogoneticus quitzeoensis in having a shorter preorbital distance (Prol/SL mean = 0.056, SD =0.01); a longer dorsal fin base length (DFL/SL mean = 0.18, SD = 0.03); 13-14 dorsal fin rays (Ref. 83562).

The type locality is a permanent spring of lentic and clear waters and forms a small pond of approximately 1500 sq.m; the bottom rocky in its periphery and muddy in most of the pond. Aquatic vegetation composed of Iris sp. and Ceratophyllum sp, emergent vegetation Typha sp. and Scirpus sp., and the introduced species Eichhornia sp; the terrestrial vegetation is of the subtropical forest type. Associated fish fauna are the native species, Alloophorus robustus, Chapalichthys encaustus, Goodea atripinnis, Skiffia multipunctata (Goodeidae); Poeciliopsis infans (Poeciliidae); Lampetra geminis (Petromyzontidae); and introduced species Poecilia mexicana, Xiphophorus hellerii (Poeciliidae), Oreochromis spp. (Cichlidae), Cyprinus carpio, and Ctenopharingodon idella (Cyprinidae) (Ref. 83562).

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.2 ±0.1 se; based on size and trophs of closest relatives

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