Species Description: Nunez JJ, Rabanal FE, Formas JR 2012 Description of a new species of Eupsophus (Amphibia: Neobatrachia) from the Valdivian coastal range, southern Chile: an integrative taxonomic approach. Zootaxa 3305: 53-68.

Eupsophus altor can be distinguished from other species by the following prominent cranial characteristics: deep palatal shelf of premaxilla, large pterygoid process, small nasals, nasals contacting maxillae, a type II cervical cotylar arrangement, moderately long zygomatic ramus of squamosal, long otic ramus of squamosal, broad and separate odontoid-ridge-bearing palatines, spheno-ethmoid whole and extends to contact with anterior edge of nasals. Endotrophic tadpoles. Differentiated from other Eupsophus species by its wintertime breeding, terrestrial tadpoles and unique advertisement call (Nuñez et al. 2012).
In both life and in preservative, dorsal coloration ranges from reddish to pink. Flank coloration is white with yellow in the axillary and inguinal areas. Ventral coloration is white. Light-gray spots are present on the dorsal surface, light-gray bracelets are present on the extremities, small melanophores distributed on ventral surface and the iris is yellow with black networking. In preservative, color is similar to color in life. (Nuñez et al. 2012).

The species authority is Nuñez, Rabanal, and Formas (2012).
This species was once thought to be Euposophus roseus, however, recent molecular analyses shows that Eupsophus altor is a separate and distinct lineage from E. roseus (Nuñez et al. 2012). The name, altor, is derived from Latin, meaning “one who looks after or brings up its offspring.” It is given because males were observed near clutches of tadpoles (Nuñez et al. 2012).
