Range and distribution edit

Rhombophryne vaventy is endemic to the Marojejy massif in northern Madagascar, where it was originally described from two individuals, captured at high altitude.[4]

Description edit

Rhombophryne vaventy measure up to 52 mm (2.0 in). In life, the dorsal skin is highly textured. It lacks webbing between the fingers and toes, and has very long legs.[4] It possesses four unequally sized spines above each eye, characteristic of its species group.[4]

Habitat and ecology edit

Rhombophryne vaventy is found in montane rainforest at high altitude (~1,300 m (4,300 ft) above sea level) on the Marojejy massif. Like most Rhombophryne species, R. vaventy is a terrestrial or possibly semi-fossorial frog. It is a generalist predator, and its diet is known to include relatively large arthrosphaerid pill millipedes of the genus Zoosphaerium.[4] Nothing is currently known of its breeding or calling behaviour.

Taxonomy edit

Rhombophryne vaventy was confused with R. serratopalpebrosa until the taxonomy of the R. serratopalpebrosa species complex began to be resolved.[4] It differs from R. serratopalpebrosa in its size, eye spines, skin texture, and numerous other characters.[4] Ongoing resolution of this complex has yielded several new species, including R. ornata and R. tany.
