Dorsal surface of legs white with distinct narrow black bands. Venter white with dark spots, which are more or less circular on the throat and become more oblong towards the abdomen. Skin smooth. Nostrils nearer to tip of snout than to the eye. Tympanum very distinct, about 1/2 of eye diameter. Tibiotarsal articulation reaches the eye. Lateral metatarsalia partly connected. Webbing rudimentary. Fingers with terminal disks. Oblong femoral glands clearly visible in males.Similar species: Colouration is unique. Morphology is similar to the M. wittei-complex.Taken with permission from Glaw and Vences (2007).

Life History, Abundance, Activity, and Special Behaviors
provided by AmphibiaWeb articles
Near Threatened: area of occupancy is less than 2,000 km2, and the extent and quality of its habitat is declining, thus making the species close to qualifying for Vulnerable. It occurs in Parc National de Ranomafana, Parc National d’Andringitra and Parc National d’Andohahela, and in the Réserve Spéciale du Pic d'Ivohibe (Nussbaum et al. 2008).

Spinomantis bertini
provided by wikipedia EN
Spinomantis bertini is a species of frog in the mantellid subfamily Mantellinae, endemic to Madagascar.[2]
Taxonomy
This species was described in the genus Gephyromantis by Guibé in 1947.[3] It was transferred to the genus Mantidactylus by Blommers-Schlösser in 1979.[4] Dubois put it in the subgenus Spinomantis,[5] which was elevated to genus-level in 2006.[6]
Distribution and habitat
S. bertini has a relatively broad distribution in south-eastern Madagascar, at elevations of 500–1,300 m (1,600–4,300 ft) above sea level. It inhabits crevices among boulders and rocky areas, usually close to flowing waters, in pristine forest habitats; the species is not found in degraded forests or secondary growth.[1]
Conservation
The species is classified as Near Threatened by the IUCN. It is under pressure from habitat loss through expansion of agriculture, timber and coal production, and settlements, as well as the spread of invasive plants like eucalypts.[1]
