Arcovomer is a genus of frogs in the family Microhylidae.[2] It is monotypic, being represented by the single species Arcovomer passarellii, commonly known as Passarelli's frog.[3] It is endemic to south-eastern Brazil and found in Espírito Santo, Rio de Janeiro, and São Paulo states. Frogs from Espírito Santo may represent another, undescribed species.[2] The name honours Antonio Passarelli who collected the holotype.[4]

Description and behaviour

Arcovomer passarellii is a small, slender-bodied frog. The male is about 16–20 mm (0.63–0.79 in) in snout–vent length, and the female 22–26 mm (0.87–1.02 in).[4] Its body is brown above with a distinct irregular dark pattern running the whole length of the animal.[4][5][6]

Male frogs call after sunset. The advertisement call is a sharp, short whistle. When disturbed, these frogs may jump and then assume a stiff-leg posture, possibly as a means to avoid detection by predators relying on their sight.[5]

Habitat and conservation

This species inhabits lowland primary and secondary forests. It is a ground-dwelling frog that breeds in temporary pools. Although it is a common species, it is declining in abundance, probably because of habitat loss.[1]
