Guibemantis albolineatus

Guibemantis albolineatus, also known as the white-lined Madagascar frog, is a species of frog in the family Mantellidae. It is endemic to Madagascar.[1][2][3] It is known from the southeastern part of the island. However, there is some confusion between this species and Guibemantis bicalcaratus, as well as possibly undescribed species, making its actual distribution unclear.[1]

Description

Both males and females grow to about 24 mm (0.9 in) in snout–vent length,[3] although they are often smaller. The snout is square in dorsal and ventral view.[4] The fingers have rudimentary webbing whereas the feet are partially webbed. Dorsal skin is smooth. Coloration is chocolate brown with two greenish dorsolateral bands. Males have distinct and well-delimited femoral glands.[3]

Habitat and conservation

Guibemantis albolineatus is an arboreal frog inhabiting pristine rainforest at elevations of 300–1,500 m (980–4,920 ft) above sea level. It is in particular associated with Pandanus species (as is typical for the subgenus Pandanusicola[4]). The eggs are deposited in leaf axils, often those of Pandanus, and the tadpoles develop in this same microhabitat.[1][3] It is a rarely recorded species that is threatened by habitat loss. It is present in Andohahela and Marojejy National Parks, and probably in other protected areas too.[1]
