Spinomantis peraccae

Spinomantis peraccae is a species of frog in the mantellid subfamily Mantellinae. It is endemic to Madagascar and widely distributed in the northern, eastern, and central parts of the island.[1][2] The specific epithet honours Italian herpetologist Mario Giacinto Peracca.[3] Common name Peracca's Madagascar frog has been coined for it.[1][2]

Taxonomy

George Albert Boulenger described this species in 1896 within the genus Rhacophorus.[4] Rose M. A. Blommers-Schlösser transferred it to Mantidactylus in 1978.[5] Alain Dubois placed it in the then-subgenus Blommersia in 1992,[6] but it was moved to the then-subgenus Spinomantis by Glaw and Vences in 1994.[7]

Description

Adult males measure 34–44 mm (1.3–1.7 in) and adult females 39–45 mm (1.5–1.8 in) in snout–vent length. The snout is rounded. The tympanum is distinct and supra-tympanic fold is prominent. The fingers have expanded discs but no webbing; the toes are webbed but the discs are smaller than those on the fingers. The dorsum is brownish-greenish and has darker blotches. Dorsal skin is rather warty with dark, protruding dots. The lower parts are whitish; there are few dark spots on the throat.[8]

Geographic range

It is endemic to the eastern half of Madagascar.[1][2]

Habitat

Spinomantis peraccae occurs in pristine rainforest along streams at elevations of 500–2,000 m (1,600–6,600 ft) above sea level. It is arboreal. The eggs are laid on leaves above water. The tadpole develop in slow-flowing streams.[1]

Conservation status

Spinomantis peraccae is a locally abundant species, but it is suffering from habitat loss. It occurs in many protected areas. Because of its wide range and large overall population, it is not considered threatened.[1]
