Description
Bufo amabilis is a new species recently discovered by John D. Lynch. It is the largest Bufo in the Bufo spinulosus group. Its average SVL is 82.6. It is characterized by a number of different features such as a large, defined tympanum with a plectral apparatus. It has a long, triangular snout, and its head is wider than it is long. The posterior parotoid glands are larger, more ovoid and broader than those anteriorly. They have sexually dimorphic glandular formations. The males have glandular and warty formations with a single keratinous spine per glandular formation (except on certain points on limbs and flanks). The females are less glandular and rarely have keratinous spines. The ventral granules are large and elevated. Digit I is of equal length to digit IV. The hind limbs are long, with basal webbing on the feet with about half of the toes webbed. The fingers, however, are not webbed. The cranial crest and tibial glands are absent.
