[call details here]

Description
M 34-44 mm. The only arboreal Spinomantis without distinct fringes or spines. Usually light brown to greenish on the dorsum with distinct rounded brown patches.

Variation: Specimens from Tsaratanana, have a more brownish colour and indistinct patterning and very melodious, “metallic”-sounding calls, and may represent a different species.

Similar species: M. massi has rudimentary but clearly recognizable dermal flaps. M. elegans is larger, with a less granular skin and has only an inner metatarsal tubercle. Boophis species never have an outer metatarsal tubercle.

Distribution and Habitat

Country distribution from AmphibiaWeb's database: Madagascar

View distribution map in BerkeleyMapper.

Ambohitantely, Andranomay forest, Anjanaharibe, Ankazobe, Ankeniheny, Chaines Anosyennes, Farihimazava, Ranomafana (Maharira forest, Ranomena, Vohiparara). It occurs between 500m-2,000m asl in pristine rainforest (Andreone et al. 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: One specimen was found in a Pandanus leaf axil . One calling male was captured in February, about 5 m above a brook in rain forest. Several other specimens were heard along forest brooks.

Call (from Ankeniheny): A single 'explosive' short note that can be described as 'pom'. Note duration is about 75 ms. Frequency is between 1.2 and 4.2 kHz, with intensity maxima at 1.3 and 2.6 kHz. Call is repeated after intervals of at least about 30 seconds. Similar calls were heard at Andasibe.

Breeding takes place in slow-moving streams (Andreone et al. 2008).

Trends and Threats
It occurs in many protected areas (Andreone et al. 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
