Isthmura (Pseudoeurycea) naucampatepetl is a small member of the Isthmura (Pseudoeurycea) bellii complex. It is distinguished from its congeners by its coloration/pattern consisting of a pair of prominent, pink, rather than orange spots, on the head, a pair of similarly colored triangular shoulder spots followed by a series of ten pairs of small costal spots and a distinctive U-shaped spot above the pelvic region. The largest male attained a SVL of 82.1 mm (smallest male 67.6 mm) and the largest female attaining 82.9 mm. Broadly rounded, large snout with protuberant eyes. Head is broad, 14.3-16 svl. Adpressed limbs meet, slightly overlap, or slightly fail to overlap in males but fail to overlap by one to one-half costal folds in females. Fingers in order of decreasing length of 3-2-4-1; toes in order of decreasing length 3-4-2-5-1. Tails 74-84% SVL. Premaxillary teeth 3-4 and slightly enlarged in males, indistinguishable in females (Parra-Olea et al. 2001).

This species is only known from along a narrrow ridge extending east from Cofre de Perote and ends at Cerro Volcancillo at the type locality in the Sierra Madre Oriental in central Veracruz.

Life History, Abundance, Activity, and Special Behaviors
All specimens were found by scraping the surface of roadcut banks which consisted of moist soil with a dry outer crust. Most of these banks were shaded.
