Bolitoglossa meliana is most comparable to B. psephena by having a uniformly dark dorsum, but differs is having a squared snout in dorsal profile, a more slender body, and longer, narrower toes with truncate toe tips and less webbing. Bolitoglossa meliana is also a highland dry pine-oak forest to cloud forest species found at lower elevations of 1550 - 2730 m than B. psephena. Bolitoglossa franklini is distinguished from B. psephena by the former having a squared snout in the dorsal view, less webbing on the hands and feet, and a pattern of silvery gray, greenish, or orange spots and blotches on a black background. Additionally, the forearm and lower leg are considerably more robust than in both B. meliana and B. franklini. Bolitoglossa lincolni is a large species with a dramatic design of red and black that distinguishes it from B. psephena. Bolitoglossa morio is typically smaller than B. psephena in standard length, however, large female B. morio are occasionally equal to are larger than B. psephena. Bolitoglossa morio are also slightly more robust, have a relatively shorter tail, and no digit webbing. The two species also differ in coloration and patterning with B. psephena being almost uniformly dark over the whole body and B. morio having irregular white or pinkish spots or mottling on the flanks and venter (Campbell et al. 2010).
In life, B. psephena is generally uniformly dark over the whole body. When in preservative, the skin color turns to a uniform dark gray (Campbell et al. 2010).
