Material. ANGOLA – Cabinda Province • Mayombe NP, Sanga Mongo; –4.6661, 12.4407; 146 m a.s.l.; FKH 0970; GenBank: PQ455703. • Mayombe NP, Bata Lunhuca; –4.5981, 12.4597; 215 m a.s.l.; P4.085; GenBank: PQ455702. • Mayombe NP, Miconge; –4.4860, 12.8780; 377 m a.s.l.; FKH 1035−37, FKH 1045, FKH 1048; GenBank: PQ455704–08.

Identification. Arthroleptis sylvaticus also represents a species complex with three distinct mitochondrial lineages (Larson and Zimkus 2018; Deichmann et al. 2017). Material from Cabinda Province is identical to material from the Republic of the Congo (GenBank: KY080080), which represent the closest genetic samples available from the type locality of Buta, DRC (Deichmann et al. 2017), still 1,300 km from the type locality. Also, it is genetically identical to material from Uíge Province, Angola (Baptista 2024). Therefore, material from Cabinda Province and northern Angola may represent true Arthroleptis sylvaticus . However, due to the large distance from the type locality we suggest caution and recommend further taxonomic investigation.

Biology and distribution. Members of the A. sylvaticus complex are distributed in the Congo Basin. The specimens from Cabinda Province were found in dense rainforest among leaf litter near streams in Lower and Upper Mayombe.
