Hyperolius vilhenai

Hyperolius vilhenai is a species of frog in the family Hyperoliidae. It is only known from its type locality, Cuílo, along the Luita River in northern Angola,[1][2] although it is likely to occur in adjacent Democratic Republic of the Congo.[2] Additional specimens from the Cangandala National Park have been provisionally assigned to this species.[1] The specific name vilhenai honours Ernesto Jardim de Vilhena, a Portuguese naval officer, politician, and businessman.[3] Common names Luita River reed frog and Vilhena's reed frog have been proposed for this frog.[1][2][3][4]

The holotype, an adult male, measures 21 mm (0.8 in) in snout–vent length. It has a squat body and a large, broad head. The snout is rounded. Colouration is pale green. A dark band runs from tip of snout to upper eyelid. The specimen has neither gular flap not gular sac. It is the only specimen assigned to this species with confidence.[4][5]

Habitat and conservation

Hyperolius vilhenai was apparently found in gallery forest in the humid savanna zone.[1] Its ecoregion of occurrence is the Angolan miombo woodlands.[4] Information on threats to this species is lacking. It might be present in the Cangandala National Park.[1]
