Identification. A large hyperoliid (SVL = 54 mm) that can be distinguished from other members in the family by its characteristic black and yellow-orange stripes on the hind limbs and brownish dorsum. Specimens from the study area are identical (16S p -distance) to material from Gamba, Gabon (GenBank: KY080267 ), ∼ 300 km from N’Djolè, where a lectotype was restricted ( Frétey et al. 2014) .

Biology and distribution. A nocturnal tree frog that is known to occur in Equatorial Guinea, Gabon, Republic of the Congo and DRC ( Channing and Rödel 2019). This material represents the first records of this genus for Angola and Cabinda Province ( Baptista 2024). On one occasion, specimens in this study were observed jumping to the ground from 4 m high in the forest during a rainstorm, and breeding in a deep rain pool at the edge of the primary rainforest, in Lower Mayombe.
