The frog genus Atelognathus is currently represented by nine species distributed in Argentinean and Chilean Patagonia. It is mainly distributed in Argentina, and there are only three species in Chile (A. ceii, A. grandisonae and A. jeinimenensis). Regarding the morphological relationships among Atelognathus species, Meriggio et al. (2004) suggest that A. jeinimenensis is more related to A. salai than other species. A. salai was described from Laguna Los Gendarmes (Argentina), 90 km air line from the type locality of A. jeinimenensis. This paper presents a morphological analysis and a study of population genetics using mtDNA nucleotide data from Argentinean and Chilean localities to assess the genetic distance between A. salai and A. jenimenensis. We obtained 477 bp-long d-loop sequences from 51 Atelognathus specimens collected in four localities. According to our results, the morphological differences between A. salai and A. jeinimenensis populations are limited to size, and there are no distinctive characteristics that would separate two species, in addition to which a simple geographic pattern of genetic diversity suggests a single species of Atelognathus. Also, the populations from Chile (Cerro Castillo, RN Lago Jeinimeni and Chile Chico) and Argentina (Laguna de Los Gendarmes) have low levels of genetic divergence that may be consistent with glaciations during the Late Pleistocene. We propose Atelognathus jeinimenensis as a junior synonym of A. salai and that the Chilean populations should be assigned to A. salai.

Abstract Araucaria araucana (Mol.) K. Koch is one of the most important native species of Chile and Argentina, and also one of the most endangered. In this study, we report the development and characterization of a set of microsatellite markers in the species by means of the microsatellite-AFLP (M-AFLP) technique. A total of 25 M-AFLP derived bands, showing a typical microsatellite pattern, were selected and sequenced. Of these, 12 that contained microsatellite sequences, were used for primer extension. Six of the resulting SSR markers provided easily interpretable patterns and were used to investigate the level of genetic diversity in two populations of A. araucana. A total of 43 alleles were amplified. The mean overall loci of observed and expected heterozygosities for the Conguillio and Villa Araucaria populations were 0.322 and 0.443, respectively. The primers presented in this study may provide useful information for the establishment of a conservation strategy in the species.
