Material. ANGOLA – Cabinda Province • Mayombe NP, Sanga Wanda; –4.6270, 12.4527; 215 m a.s.l.; P3.513, P3.515; GenBank: PQ455853–54. • Mayombe NP, Bata Lunhuca; – 4.5981, 12.4597; 215 m a.s.l.; P4.084; GenBank: PQ455855.

Identification. A medium-sized Leptopelis (SVL = 42–57 mm) with characteristic white spurs on the heels. The specimens from Cabinda Province differ by 3.8–4% (16S p -distance) from material collected from Sapia, Cameroon (GenBank: KT967090, KT967091), ∼ 100 km south of the type locality at Efoulan, Cameroon. The large genetic distance suggests cryptic diversification within L. calcaratus . We therefore listed the material from Cabinda Province as Leptopelis cf. calcaratus, pending further investigation.

Biology and distribution. An arboreal Leptopelis widely distributed in the Gulf of Guinea and the Congo Basin,from Nigeria eastwards to DRC (Channing and Rödel 2019). The species had recently been reported from northwestern Angola (Ernst et al.2020; Baptista 2024), but these specimens constitute the first records of the species for Cabinda (Baptista 2024).
