Bolitoglossa splendida is close in size to other Bolitoglossa species like B. gomezi, B. pesrubra, and B. subpalmata. However, it has a relatively broad head that differentiates from B. bramei, B. gracilis, B. gomezi, B. pesrubra, B. subpalmata, and B. tica (Boza-Oviedo et al. 2012).
Bolitoglossa splendida is jet black coloration on the dorsal and lateral areas but paler on the ventral area. There is a dorsolateral band, varying between bright red or orange-red, that begins on the back of the head and extends to the base of the tail. The band is split at the base of the head into two stripes that extend to the back of the eyelids. The nasolabial protuberances are pale in contrast to the black coloration of the skin. The band has no breaks in it but has some melanin speckling. The lateral edge of the band is irregular. Bright yellow spots can be observed unevenly distributed on the lateral and ventrolateral surfaces (Boza-Oviedo et al. 2012).

General habitat alteration and loss
Based on Bayesian and Maximum Likelihood analyses on 16S and cyt b mtDNA, B. spendida, forms a polytomy with B. gomezi, the clade composed of B. bramei, B. kamuk, and B. pesrubra, and the clade composed of B. gracilis, B. subpalmata, and B. tica (Boza-Oviedo et al. 2012).
The species epithet, “splendida” comes from the Latin word, “splendidus,” which means “distinctly vivid in appearance” (Boza-Oviedo et al. 2012).
