Redescripción de la morfología larval externa de dos especies del grupo de Leptodactylus fuscus (Anura, Leptodactylidae)

Abstract

The larvae of Leptodactylus gracilis (D’Orbigny y Bibron, 1840) and L. mystacinus Bumeister, 1861 are re-described and compared with previous descriptions noting intraspecific variation in oral disccharacteristics (arrangement of papillae and rows of cornified teeth). The external morphological analysis of larvae of the Leptodactylus fuscus group suggest that the lack of comparable descriptions among species, as well as the lack of analyses of theirintraspecific variation, limits the use of larval characteristics for diagnostic purposes.
