In general, C. casasi differs from C. aureus, C. ceronorum, C. lavae, C. melipona, C. nubilus, C. orculus, C. perotensis, and C. totonacus because of its larger body size in adults. When compared to C. chriopterus the female has a larger body size. Chiropterotriton casasi can be distinguished from C. chriopterus, C. melipona, C. nubilus, and C. totonacus due to its shorter tail. When compared to all of the species listed above C. casasi can be distinguished by its longer head except for C. totonacus, in which only the female C. casasi head is longer. Chiropterotriton casasi also has a broader head than all listed with the exceptions of C. chriopterus and C. totonacus. Chiropterotriton casasi has shorter limbs than C. lavae and C. totonacus and longer limbs than C. aureus, C. melipona, C. nubilus, and C. orculus (Parra Olea et al. 2020).
Only coloration in preservatives is known. Preserved specimens are a faded brown color, with mottled snout and limb coloration and a paler head and ventrum. There may be a pale band between the eyes. The dorsal end of the tail has a light stripe (Parra Olea et al. 2020).
Most of the morphologic measurements for both sexes are within the same intervals, except for the number of vomerine and maxillary teeth, which are more numerous in the female. The female specimen is mottled over its entire body, which is faded and dark brown. The female specimen also shows a light dorsal stripe at the base of the tail. Some specimens also exhibit a pale interorbital band (Parra Olea et al. 2020).

Chiropterotriton casasi was placed in the genus Chiropterotriton based on morphometric and osteological comparisons because genetic material is not available for phylogenetic analysis. As such, its exact placement in the genus is unknown as of 2022 (Parra Olea et al. 2020).
The species epithet, “casasi” is in honor of Mexican herpetologist Gustavo Casas Andreu who greatly contributed to the biodiversity of Mexican amphibians and reptiles (Parra Olea et al. 2020).
