Pseudoeurycea ruficauda is a medium-sized arboreal tropical salamander from Oaxaca, Mexico with long legs and widely splayed hands and feet with long separated digits. Along with the previous characters, its vivid coloration sets it apart from other congeners: red-orange tail and mottled black and orange head and body; an irregular and often discontinuous dorsal stripe that varies from tan-yellow to orange to reddish-brown extends from nape to tip of tail. Flanking black bands run from the scapular region to the base of the tail where they are broken into isolated spots dispersed over the tail. In many specimens there is a V-shaped mark on the head, beginning on upper eyelids with apex pointed posteriorly. P. ruficauda has a less robust body relative to its congeners and closest relative, P. unguidentis (Taylor, 1941), with slender legs and tail, and a prominent head which is differentiated from the trunk (i.e. a distinctive “neck”). Live specimens are also jumpy and tend to behave like P. saltator. Subadults range from 23.7-30.2 mm SVL, but adults may reach up to 45 mm. Members have a large, anteriorly directed eyes that protrude beyond the silhouette of the head. Nostrils are small, widely separated; head width ranges from 4.2-5 mm. Costal grooves are 13. Tail tapers to a narrow tip. Legs are long and usually overlap by 1-1.5 costal folds when adpressed. Fifth toe is well developed but noticeably shorter than the fourth. Teeth relatively numerous: premaxillary 5-8, maxillary 27-49, and vomerine 11-16.

This species is known from two general localities in the western portion of the Sierra Mazateca, Oaxaca. Both localities lie within high elevation, moist, pine-oak forest, with oaks dominating at present. Found under logs and bark. Two were found in bromeliads 2 m above ground.

Pseudoeurycea ruficauda, also known as the orange-tailed agile salamander, is a species of salamander in the family Plethodontidae. It is endemic to the Sierra Mazateca, a part of Sierra Madre de Oaxaca of Mexico.[2][4] The specific name ruficauda derives from the Latin words rufous (=reddish) and cauda (=tail) and refers to the reddish orange tail of this salamander.[3] P. jaguar is its closest relative.[1]
Description
Pseudoeurycea ruficauda can grow to 45 mm (1.8 in) in snout–vent length (SVL). The tail is slightly shorter than SVL in most individuals. The head is relatively large with large, protruding eyes. The body is slender and the legs are long. The hands and feet are broadly spread and have long, separated digits. Dorsal coloration is orange-tan with coppery-gold highlights mixed with black. The dorsal stripe is irregular and sometimes interrupted; its color varies from tan-yellow to orange to reddish brown. The tail is orange with black spots and a vivid, red-orange to yellow-orange tip.[3]
Habitat and conservation
Pseudoeurycea ruficauda occurs in moist, mixed pine and oak forest at elevations of 2,235–2,290 m (7,333–7,513 ft) above sea level. It is arboreal and can be found under the bark of logs, in epiphytes, and in stone crevices. Presumably, development is direct[2] (i.e., there is no free-living larval stage[5]).
Although common within its known range consisting of only two localities, the quantity and quality of its habitat are declining because of small-scale farming and wood extraction. It is not known to occur in any protected areas.[2]
