Chorti Worm Salamander
Species Description: Brodie ED Jr, Acevedo M, Campbell JA 2012 New salamanders of the genus Oedipina (Caudata: Plethodontidae) from Guatemala. J Herpetology 46: 233-240.
Diagnosis: Oedipina chortiorum can be distinguished from other members of the Oedipina subgenus by its costal grooves (14-15), intercostal folds (10-12), wide hands and feet (mean 1.55 and 2.10 mm, respectively), short tail (a little less than 1.5 times the snout-vent length), teeth (14-15 vomerine, 32-38 premaxillary plus maxillary), and digital webbing that extends to nearly the tip of its digits (Brodie et al. 2012).
Coloration in life: Oedipina chortiorum is almost uniformly black. The venter is slightly less dark than the dorsum (Brodie et al. 2012).
Coloration in preservation (alcohol after formalin): The body and top of the head is gray. The tail is mostly gray and is distally pale. The venter is slightly paler than the flanks of the boy and dorsum. The throat is a both a pale cream and gray color. The limbs are gray but are paler than the body (Brodie et al. 2012).
Variation: Oedipina chortiorum can have a snout length of 47.0-52.0 mm, head width of 5.00-5.20 mm, and head length of 7.20-7.60 mm. Individuals can have anywhere between 14-15 vomerine teeth and 32-38 premaxillary plus maxillary teeth. There can be 10-12 intercostal folds between adpressed limbs and their hands and feet have a mean of 1.55 and 2.10 mm, respectively (Brodie et al. 2012).
