Reproduction and larval morphology af adenomera diptyx (anura: leptodactylidae) from the Argentinean humid Chaco an Brazilian Pantanal

Whereas the external larval morphology of some species of Adenomera has been described, their internal morphology remains poorly studied. In this work, we provide information on the reproductive features and larval morphology of populations of Adenomera from northeastern Argentina and southwestern B...
