Abstract

We tested the phylogenetic position of Anaxyrus kelloggi, a distinctive toad species from coastal northwestern Mexico, using a ~2.4-kilobase fragment of mitochondrial ribosomal RNA gene regions and maximum likelihood and Bayesian analyses. The two approaches recovered nearly identical phylogenetic topologies, which provide strong support for placement of A. kellogi in the debilis group, as sister taxon to the clade formed by A. debilis and A. retiformis. Species relationships within the debilis group are also well supported and concordant with aspects of earlier, morphology-based hypotheses.

Evaluamos la posición filogenética de Anaxurus kelloggi, una especie de sapo distintivo de la costa noroeste de México utilizando ~2.4 kb de un fragmento de regiones del ARN ribosomal en el gen mitocondrial y análisis de máxima verosimilitud y bayesianos. Los dos criterios recobraron topologías filogenéticas casi idénticas, la cual provee alto soporte de la afiliación de A. kelloggi dentro del grupo debilis, como hermano al clado conformado por A. debilis y A. retiformis. Las relaciones de especies dentro del grupo debilis tienen alto apoyo y concuerdan con aspectos de las hipótesis previas basadas en morfología.
