Las supuestas razas de Bufo arenarum y el concepto de subespecie críptica

Abstract

The author checking the alleged subspecies of Bufo arenarum, by biometrical methods, concludes that they are too poorly differenciated to be maintained, except B. arenarum mendocinus Philippi, which has such sharply defined physiological and serological characters that it may serve as an example of a valid cryptic subspecies.
