Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10 - 12; Anal soft rays: 9 - 14; Vertebrae: 32 - 34. This new species of the subgenus Profundulus shares similar characters with members of the subgenus (viz., P. (P.) punctatus, P. (P.) guatemalensis, P. (P.) oaxacae): dark humeral spot, a scaled preorbital region and between 32-34 vertebrae. It differs from other members of the subgenus by having less than half of its caudal fin densely covered with scales; from P. oaxacae and P. punctatus by the not having conspicuous brown spots on the sides of the body; from P. guatemalensis by having fewer pectoral-fin rays, (13-16 vs. 17-20) and caudal-fin rays (13-18 vs.19-23); from P. guatemalensis, P. punctatus, by having a golden blotch covering most of the operculum and reaching the base of the pectoral fin. Profundulus (P.) kreiseri differs from all members of the subgenus Tlaloc (viz., P. (T.) candalarius, P. (T.) hildebrandi, P. (T.) labialis, P. (T.) portillorum) by the presence of a dark humeral spot and a scaled preorbital. It further differs from P. (T.) candalarius, P. (T.) hildebrandi, P. (T.) labialis by having 32-34 vertebrae (vs. 35-39) (Ref.91935).

The area where the species was collected from are both characterized as small tributaries ranging from 0.8 to 4 meters in width with stones (from pebbles to boulders) as the dominant substrate; estimated canopy cover of both localities 70-80%; and both creeks feature a variety of run, pool, riffle, rapid and small waterfall habitats (Ref. 91935).

Bayesian length-weight: a=0.01349 (0.00545 - 0.03342), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.4 se; based on size and trophs of closest relatives

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