Figure 8S

Material. ANGOLA – Cabinda Province • Mayombe NP, Chimbete; –4.6631, 12.5447; 182 m a.s.l.; P3.145; GenBank: PQ455973 .

Identification. A large snake (max. SVL = 1190 mm) with dorsum brown or grey with numerous black transverse bands ( Chaney et al. 2024). Material from Cabinda Province is almost identical (<0.5% 16S p -distance) to that of G. ornata sensu stricto (fide Chaney et al. 2024) from Ogooue, Gabon (GenBank: AY611866 ).

Biology and distribution. Grayia ornata is an aquatic snake widely distributed in Central Africa from Gabon to the westernmost region of the DRC and northern Angola ( Chaney et al. 2024). The species is typically found in a variety of aquatic habitats ( Chippaux and Jackson 2019). The specimen reported here was found at night in a deep pool at the edge of a slow-moving forest stream in Lower Mayombe.
