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.This species is based on the following publication: Pramuk, J.B. and F. Kadivar. 2003. A new species of Bufo (Anura: Bufonidae) from southern Ecuador. Herpetologica, 59, 2003, p 270-283.

The first species were collected from Provincia Loja, Ecuador in the inter-Andean valley. B. amabilis and the B. spinulosus are the only species that occurs north of the Huancabamba Depression. B. Amabilis can be found in the Matorral Seco Montano Sierra life zone. This area has a mean annual rainfall of 250-500 mm with a mean annual temperature of 7-12°C.

Rhinella amabilis is a species of toads in the family Bufonidae that is endemic to Ecuador,[3][4] only occurring in a severely fragmented area less than 100 square kilometres (39 sq mi).[1]
Description
Males measure 49–97 mm (1.9–3.8 in) and females 50–85 mm (2.0–3.3 in) in snout–vent length.[4]
Range
This species is known only from elevations of 2,050 to 2,200 metres (6,730–7,220 ft) above sea level in the Loja Basin, an inter-Andean valley in Loja Province, Ecuador.[1][2][3][4] It has a restricted distribution, as surveys have confirmed.[1]
Conservation status
It is currently listed as Critically Endangered, in view of its small and fragmentary extent of occurrence and the fact that there is a continuing decline in the extent and quality of its habitat.[1]
The apparent declines of this species might in part be due to the modification of much of the Loja basin area for agriculture, urbanization, and other regional development. It appears that populations of this toad in the area surrounding Provincia Loja have been severely affected by human activities.[2] Disease might also be a factor but there is no evidence to confirm this.[1]
Population
Past collections indicate that the species was fairly common at areas nearby creeks, even near plantations; however, surveys undertaken between 1989 and 2001 failed to find the species. It appears that it has not been collected since 1968, and a serious decrease might have taken place.[1]
Habitat and ecology
The species has been collected in small pools and irrigation canals. Little is known of its habitat requirements or ecology, but breeding is presumed to take place in freshwater by larval development.[1] It is active by night.[4]
