Identification. Material from Cabinda Province is almost identical (0.2% 16S p -distance) to material ascribed to C. leucomystax 1 (sensu Blackburn et al. 2021) from the Bandjoko, Republic of the Congo and Ivindo, Gabon (GenBank: MW624175, MW624173),and identical to other material from Lekoumou, Republic of the Congo (GenBank: KY080101).Our records represent the southernmost records of the species, and the first for Angola (Baptista 2024).

Biology and distribution. The species appeared to be more common at higher elevations in Upper Mayombe, and all specimens were found near fast-flowing forest streams, either at the water edge or on sandbanks.
