Muscular Salamander, Salamandra Escaladora
Species Description: Parra-Olea G, Garcia-Paris M, Hanken J, Wake DB 2005 Two new species of Pseudoeurycea (Caudata: Plethodontidae) from the moutains of northern Oaxaca, Mexico. Copeia 2005:461-469
This species is distinguished from other species in the subfamily Bolitoglossinae by its muscular form. Pseudoeurycea smithi is closely related, and P. papenfussi has been misclassified in the past as this species. Pseudoeurycea papenfussi can be distinguished from P. smithi by having longer limbs and more teeth. When compared to Pseudoeurycea aquatica, P. papenfussi has shorter limbs and digits, a less depressed head, open nostrils (opposed to closed), and more maxillary teeth. Molecular features such as proteins and mtDNA sequences are also distinct (Parra-Olea et al. 2005).
In life, P. papenfussi is a chestnut-brown ground color. The coloration is paler near the head and darker near the tail, which generally has a brighter reddish-brown hue. Dark brown-gray costal grooves extend to the pale tan venter, which has a light chestnut hue. When preserved in alcohol, Pseudoeurycea papenfussi is generally a rich golden brown color. Specimens are darkest on the dorsum, costal grooves, and grooves between muscles. Pigmentation of costal grooves extends noticeably to the mid-ventral region. A paler venter is marked with small brown spots and flecks. The head is less pigmented than the rest of the body, and the snout, upper and lower jaws margins, facial area, eyelids, and temporal areas have a pale cream coloration. The limbs are also light in coloration (Parra-Olea et al. 2005).
Some living specimens of P. papenfussi have a similar marbled dorsal pattern to P. aquatica. Preserved specimens of P. papenfussi can have darker black and brown coloring on the back, and lighter coloring on the tail (Parra-Olea et al. 2005).

Pseudoeurycea papenfussi and P. smithi are sister taxa (Parra-Olea et al. 2005).
This species was named after Theodore J. Papenfuss, from the Museum of Vertebrate Zoology at UC Berkeley (Parra-Olea et al. 2005).
