Description: Large robust toad; snout rounded; elevated parotoid glands. Dorsum dark brown with pairs of dark paravertebral patches; pairs of dark patches on snout and behind eyes that create the appearance of a pale cross on head; in PEM A12724 and A12720 a continuous dark interorbital bar is present; back of thighs often with red infusions (not always present in females or juveniles). In breeding males, the dorsum becomes yellow, with numerous small black-tipped asperites; throat darkened; enlarged arms; black nuptial pads present on palm and first finger. Adult females (n = 22) varied from 54.4– 109.7 (78.3) mm (largest female: PEM A12575); adult males (n = 37) varied from 56.7–89.2 (74.6) mm (largest male: PEM A14890). Habitat and natural history notes: Found in miombo woodland. Males were heard calling from margins of the source lakes. Comments: Widespread species across most of south-central Africa (Channing and Rödel 2019). Most historical Angolan material has been referred to as Bufo regularis Reus, 1833. Since the description of Bufo regularis gutturalis Power, 1927 (subsequently elevated to full species), the Angolan material has only partly been reassigned (Ruas 1996), and the rest of the extant material needs to be reassessed to verify the taxonomic status. Additionally, this species needs to be reassessed as other authors have demonstrated that cryptic species may be present in this taxon (Pickersgill 2007; Telford et al. 2019).
