Overview

Comprehensive Description

Description

M 23-28 mm, F 28-35 mm. A widespread species in the mid-altitude rainforests of eastern Madagascar. Tibiotarsal articulation can reach the tip of the snout. Hand without webbing, foot webbing 1(1), 2i(1), 2e(0.5-1), 3i(2), 3e(1-1.5), 4i/e(2), 5(0-1). Terminal discs of fingers and toes slightly enlarged. Dorsal skin moderately granular, usually with well-visible dorsolateral folds. Colouration dorsally very variable, often light brown with darker patches, with or without vertebral stripes, sometimes with orange flanks. Typical for this and related species is a distinct white tip on the snout. Males with a weakly distensible single subgular vocal sac, distinct femoral glands, these are relatively small and widely separated from each other.

Habitat

Habitat and Ecology

Habitat and Ecology
It lives in both intact and degraded rainforest, and is occasionally observed in deforested agricultural areas, where some shade and cover remain. It breeds in streams, pools, puddles and rice fields. Knoll et al. (2007) collected larvae from "small and very shallow, slow-flowing streams".

Justification
Listed as Least Concern in view of its wide distribution, tolerance of a wide variety of habitats, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Life History, Abundance, Activity, and Special Behaviors

Habits: Along slow-moving streams in rainforest and in secondary and disturbed vegetation at mid-elevations, also occurring in swampy areas, ditches and at the edges of ricefields. Not observed in fully deforested areas. Males call during day and (mostly) night from positions on the ground, often from within small open cavities.

Calls: A long and fastly pulsed note.

Breeding takes place in streams, pools, puddles, and rice fields (Vences and Nussbaum 2008)

Threats

Major Threats
Deforestation appears to be affecting some populations, but not others, presumably reflecting the fact that this is a complex of several species. However, as currently understood, this species is, in general, not significantly threatened.
