Electrophoretic variation of proteins encoded by 14 loci was analyzed in eight (five continental and three insular) populations of the Chilean leptodactylid frog Batrachyla leptopus. The overall proportion of polymorphic loci was estimated to be 18.7% and the average number of alleles per locus, 1.2, while observed and expected heterozygosities were 1.7 and 5.1%, respectively. The estimated coefficient of genetic identity was 0.940; the corresponding figure for genetic distance was 0.063. F-statistics analysis showed a total inbreeding coefficient (Fit) of 0.855 and high levels of genetic subdivision (Fst = 0.596) as well as of inbreeding within populations (Fis = 0.640). However, there was only a moderate level of genetic differentiation (Fst = 0.181) between the insular group of populations and the continental group.

Electrophoretic variation in proteins encoded by 15 loci was analyzed in nine populations of the Chilean leptodactylid frog Batrachyla taeniata. The overall proportion of polymorphi c loci was estimated to be 16.2% and the average number of alleles per locus, 1.18. The mean observed and expected heterozygosities for the populations were 0.9% and 5.9%, respectively. The average Rogers genetic distance among pairs of populations was 0.105. F statistics analysis showed high levels of genetic subdivision (Fst D 0:450). An isolation-by-distanc e test indicated signi cant correlation between genetic and geographica l distance.Resumen.

Resumen. Se describen los renacuajos de Alsodes vanzolinii y A. verrucosus. Las descripciones incluyen morfología externa, cavidad oral y condrocráneo. Los caracteres morfológicos externos y la cavidad oral de las larvas han sido útiles en las diagnosis específicas.Abstract. The tadpoles of Alsodes vanzolinii and A. verrucosus are described. The descriptions include external, oral cavity, and chondrocranial morphology. The external characteristics, and those of the internal oral morphology, are useful in the specific diagnosis.
