CORREA, Claudio et al. Confirmation of the presence of Alsodes pehuenche Cei, 1976 (Anura, Alsodidae) in Chile: morphological, chromosomal and molecular evidence. Gayana (Concepc.) [online]. 2013, vol.77, n.2, pp.125-131. ISSN 0717-6538.  http://dx.doi.org/10.4067/S0717-65382013000200006.

The presence of Alsodespehuenche in Chile was reported in the year 2010, based on the observation of larvae near the Chilean-Argentinean border, about 3 km east of the northeast corner of the Laguna del Maule (Región del Maule, Chile). The taxonomic history of this species dates from 1965, with the re-discovery of Telmatobius montanus (which was later transferred to the genus Alsodes) in two localities, near the Laguna del Maule and Valle Pehuenche, located in Chile and Argentina, respectively. The literature review shows that the locality of Argentina described in 1965 became the type locality of A. pehuenche, while the Chilean locality was ignored; thus this latter locality continues to be a valid record for A. montanus. In this study we provide morphological, chromosomal and molecular evidence, which confirms the presence of A. pehuenche in Chile, in two new localities located near the site recorded in 2010 and the Laguna del Maule. We also include some field observations, which are discussed in the context of the information available for this species.

Palabras clave : Andes Range; Laguna del Maule; microendemism; spiny-chest frog; Valle Pehuenche.
