Melanophryniscus macrogranulosus

''Melanophryniscus macrogranulosus'' is a species of toad in the Bufonidae family. It is endemic to northeastern Rio Grande do Sul, southern Brazil.〔 It was for a long time only known from the type series collected in 1960 (the precise location of which was unknown), until another population was discovered in 2004. This was followed by the rediscovery of population at the type locality as well as few other populations, all in Rio Grande do Sul. Its common name is Torres redbelly toad, after the type locality.〔
==Description==
''Melanophryniscus macrogranulosus'' grow to at least snout–vent length. Individuals larger than about SVL are considered adults.〔
Colouration changes through development. Dorsum in newly metamorphosed juveniles is dark gray. The ventral surface is pale, partially translucent. Palmar and plantar surfaces are also pale. Later on, palmar and plantar surfaces and the posterior region of venter show a pallid orange colour that gets more intense over time. Larger juveniles have also dark green dorsal surface of body and limbs, dark blue ventral surface with white spots, and some orange-red patches on the axils and belly. Colouration is variable in adults. The dorsal colour varies from light to dark green to almost black. Ventral surface exhibits a green or grayish blue pattern with red patches; one patch is always present on abdominal region and axils, and often in gular and pectoral region. There are small white spots covering all ventral surface, including limbs, throat, pectoral and abdominal regions. Palmar and plantar surfaces have red orange colouration.〔
Colouration is suspected to be aposematic. These toads show the unkenreflex when disturbed.〔
