Leptopelis boulengeri (Werner, 1898)

Figure 4I

Material. ANGOLA – Cabinda Province • Mayombe NP, Sanga Wanda; –4.6253, 12.4583; 221 m a.s.l.; P3.203, P3.523; GenBank: PQ455851–52 .

Identification. A large-sized Leptopelis (SVL = 48–81 mm), with characteristic angular region between the nostrils and eyes, tympanum barely visible and white spot below the eyes ( Channing and Rödel 2019). The specimens from this work are identical (16S p -distance) to material from Minkébé, Gabon (GenBank: KX260263 ). However , they differ by ∼1.6% (16S p -distance) from material from Mount Kupe, Cameroon (GenBank: KX671756 ), <90 km from the type locality ( Victoria [now Limbé], Cameroon).

Biology and distribution. An arboreal species, widely distributed in the Gulf of Guinea, including Bioko Island ( Channing and Rödel 2019). These records represent a range extension south from the previously reported southernmost record of Lekoumou, Republic of Congo, and represent the first country records ( Baptista 2024). Specimens were collected from leaves between 2 and 3 m above ground in the primary rainforest.
