Species Description: Revalidation of Rand (1952), removed from synonymy with O. taylori by Brodie ED Jr, Acevedo M, Campbell JA 2012 New salamanders of the genus Oedipina (Caudata: Plethodontidae) from Guatemala. J Herpetology 46: 233-240.

Oedpina salvadorensis is similar to Oedipna taylori and synonomyized with O. tayori from 1960 to 2012. However, O. salvadorensis has 7 - 13 premaxillary/maxillary teeth, 6 - 18 vomerine teeth, and has a geographic range that is 100 - 120 kilometers away from O. taylori. Oedipna taylori, on the other hand, have no maxillary teeth, only 5 vomerine teeth, and a larger, oval postiliac gland. The postiliac gland in O. salvadorensis is smaller and more circular (Brodie et al. 2012). Rand (1957) also mentions that O. taylori has shorter limbs with 15 costal folds between adpressed limbs vs O. salvadorensis’s 13 folds.
In life, the dorsal side of O. salvadorensis is mainly black with a slightly lighter on the ventral side giving the species an overall brownish tint. There is a white spot behind the hind leg and the top limbs are also a slightly lighter color than the bottom limbs (Rand 1957).
The specimens of O. salvadorensis are similar with regards to color and structure (Rand 1957).

PHYLOGENETIC RELATIONSHIPS:The description of Oedipina salvadorensis was published 11 days after the descriptions O. ignea and O. taylori in 1952. In 1960, Brame concluded that they all be listed under O. taylori. It wasn’t until 2012 that Brodie et al. reexamined the specimens and, based on morphological data, removed them from synonymy (Brodie et al. 2012).
