DESCRIPTION. — 34 specimens examined. Large frog with stocky body and short head, presence of a characteristic colour pattern with a green broad middorsal band, often split by a series of discontinous brown stripes, sides of dorsum dark brown with a greenish brown band on flanks from tympanic region to groin; y-shaped white stripes on the black throat (Fig. 6A).

HABITAT. — Hildebrandtia ornata was collected on garbage dumps filled after rainfalls on Kabougou River banks (W National Park). We found it as well under deadwood on the edge of a groundnut field in Koti. At Pabré, it was seen in a swimming pool in the hostel court. We saw a calling male between grasses in Arly National Park. The frog is a fossorial species which emerges only temporarily during the breeding season (Nago et al. 2006; Mohneke et al. 2010a). It occurs in dry and more humid savannahs and it is absent from forest pockets and very rocky terrain within its range (Rödel 2000; Böhme & Heath 2018). It maintains in disturbed habitats.
