A new species, Alsodes igneus, from the temperate Nothofagus forest, western slopes of the Andes Range, southern Chile, is described. This species is characterized by the combination of the following…
A NEW SPECIES OF TELMATOBIUS (ANURA: LEPTODACTYLIDAE) FROM NORTHERN CHILE
The tadpole of T. chusmisensis lack intramarginal mental papillae sharing this character with other Chilean species of the genus.
A NEW SPECIES OF TELMATOBIUS (ANURA: LEPTODACTYLIDAE) FROM RÍO VILAMA, NORTHERN CHILE, AND THE REDESCRIPTION OF T. HALLI NOBLE
The new species, Telmatobius vilamensis, from Río Vilama, near San Pedro de Atacama, Chile is described, and both taxa are compared with eight Chilean congeners that occur in the Andes.

Advertisement Calls And Relationships Of Chilean Frogs Eupsophus contulmoensis And E-Insularis (Amphibia, Anura, Leptodactylidae)
Allozymic and morphological differentiation in the South American frogs genus Eupsophus.
Four species of frogs genus Eupsophus were examined using electrophoresis at 19 loci, and 10 morphological characters employing discriminant analysis. The allozymic and morphological differentiation…
Heteromorphic sex chromosomes inEupsophus insularis (Amphibia: Anura: Leptodactylidae)
The chromosomes of the Chilean frog Eupsophus insularis are described for the first time, and based on the karyotype it is concluded that it is postulated that the Y chromosome is derived from a small ancestral metacentric chromosome that lost its heterochromatic segment.
Cytogenetic analysis of four species of the genus Alsodes (Anura: Leptodactylidae) with comments about the karyological evolution of the genus.
Transformation of euchromatin into heterochromatin and centric fissions and translocations are proposed as the main mechanisms that govern the chromosomal evolution of the frog genus Alsodes.
