Description
Adults 30-48 mm. A very unusual Spinomantis. Hand without webbing, foot webbing 1(0), 2i(0), 2e(0), 3i(1), 3e(0), 4i/e (1), 5(0). Dorsal skin smooth to very finely granular. Olive greenish with indistinct rounded brown patches. Tips of fingers and toes whitish. Males without femoral glands.

Similar species: Rather than with other Spinomantis, this species could be confused with subadult Boehmantis microtympanum.

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Madagascar

View distribution map in BerkeleyMapper.

Andohahela, Chaines Anosyennes. It occurs between 800-1,400m asl in streams of rainforest (Raxworthy and Andreone 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Observed during the day on stones and boulders in small streams in high-elevation rainforest.

It breeds outside water close to streams; the larvae then move to water, where they develop (Raxworthy and Andreone 2008).

Trends and Threats
Endangered: extent of occurrence is less than 5,000 km², all individuals are in fewer than five locations, and there is likely to be continuing decline in the extent and quality of its forest habitat in southeastern Madagascar. It occurs in Parc National d'Andohahela (Raxworthy and Andreone 2008).

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
Intensified agriculture or grazing
Urbanization
Habitat fragmentation
