Rhombophryne vaventy is a large species of frogs of the Madagascar endemic microhylid subfamily Cophylinae. It is one of the largest members of its genus.[1][2][3]

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.
