Identification. A medium-sized and robust Leptopelis (max. SVL = 62 mm). The species was originally described from Congulo in the central Angolan escarpment. Genetically, L. jordani belongs to the L. bocagii complex (Baptista 2024), from which it differs by only 1.3% 16S p -distance. It can be distinguished from the latter species by having arboreal habits (versus ground-dwelling in L. bocagii sensu stricto), well-developed discs on fingers and toes (versus absent in L. bocagii), and usually shows characteristic white leg and arm margins and spots in knees and elbows (versus absence of white markings on L. bocagii). Therefore, we ascribe specimens from Cabinda Province to L. cf. jordani based on the similar morphology to topotypic material (presence of discs and white markings) and behaviour (arboreal). However, the low genetic divergence on the 16S gene makes it impossible to resolve the taxonomy of this complex until other taxonomic tools can be applied.

Biology and distribution. The real distribution of this species is still poorly understood, but specimens ascribed to this forest-obligate, arboreal form have been recorded along the western escarpment of Angola (Baptista 2024) and now also in Cabinda Province. The specimens from Cabinda Province were found in Lower and Upper Mayombe, on leaves more than 2 m high in primary or secondary forest.
