ANGOLA – Cabinda Province • Mayombe NP, Sanga Mongo; –4.6661, 12.4407; 146 m a.s.l.; FKH 0960 , P2.081; GenBank: PQ455872−73 • Mayombe NP, Sanga Wanda; – 4.6253, 12.4583; 221 m a.s.l.; FKH 1265 ; GenBank: PQ455874 • Mayombe NP, Mbundu; – 4.6875, 12.4981; 127 m a.s.l.; FKH 1271 ; GenBank: PQ455875. • Mayombe NP, Bata Lunhuca; –4.5981, 12.4597; 215 m a.s.l.; P4.109; GenBank: PQ455876.

Identification. A small toad (SVL = 23–25 mm) with compact body, webbed fingers and toes, and short, rounded and truncated snout ( Channing and Rödel 2019). Liedtke et al. (2021) recognised three different clades within N. batesii that might justify specific status. The material from Cabinda Province represents an additional distinctive clade which differs by a minimum of ∼3.8% (16S p -distance) when compared with material of the southern clade from Liedtke et al. (2021), which includes material from Ivindo, Gabon (GenBank: KF665313 ) and Bioko Island (GenBank: MT724579 ).

Biology and distribution. An arboreal toad widely distributed in primary lowland forest of the Gulf of Guinea and Congo Basin, including Bioko Island ( Channing and Rödel 2019; Sanchez-Vialas et al. 2020). The specimens reported here represent the southernmost records of the species, and taken together with the previous species, they add a new genus to the Angolan list. The collected individuals were recorded in Lower Mayombe between 100–250 m a.s.l. and found on top of tree or bush leaves between 1 and 3 m above the ground.
