Etymology: Profundulus: Latin, profundus = deep (Ref. 45335); mixtlanensis: Derived from the word 'Mixtlan' in the Nahuatl language. The Tenoch culture used to call Mixtlan the region where the new species occurs. Mixtlan is a compound word, consisting of words Mixtli (cloud) and -Tlan (place). It means 'the place of the clouds'.

背的软条 (总数) : 10 - 13; 臀鳍软条: 12 - 21. Profundulus mixtlanensis can be diagnosed from other congeners by the following characters: a pronounced lower jaw; 30-35 lateral scales; lack dark body spotting on the posterior half of the body caused by melanization of the base of the scales; in lateral view, dorsal profile of the head shows a concavity just above the supra-occipital crest, which quickly reaches a flat profile posteriorly, an attribute that becomes more pronounced with age; body height <2/3 of SL; pre-pectoral distance <1/3 of SL; distance between ventral and anal fins 15% of SL; caudal peduncle depth 13% of SL; post-anal length 15% of SL; head length 26-28% of SL; preorbital length 26-30% of HL; eye diameter 26-28% of SL; anal-fin length 16-17% of SL; 30-35 lateral scales; 12-21 anal-fin rays; 14-17 pectoral-fin rays (Ref. 106146).
Body shape (shape guide): fusiform / normal.
Occurs in springs at altitudes between 710 and 2,300, but mostly above 2000 m (Ref. 106146).
