Sclerophrys tuberosa (Günther, 1858)

Figure 4V

Material. ANGOLA – Cabinda Province • Mayombe NP, Sanga Wanda ; –4.6253, 12.4583; 221 m a.s.l.; FKH 1258 ; GenBank: PQ455952. • Mayombe NP, Sanga Wanda; –4.6270, 12.4527; 215 m a.s.l.; P3.509; GenBank: PQ455953.

Identification. A medium-sized toad (SVL = 48–74 mm) with compact body and enlarged globose parotoid glands, and body covered with long spiny warts ( Channing and Rödel 2019). The material from the study area differs by <1% ( 16S p -distance) from material from between Malapa and Mbimb, Cameroon (GenBank: KF665246 ), and ∼2.5% from material from Lekoumou, Republic of the Congo (GenBank: KY080024 ).

Biology and distribution. The species is known to occur in lowland and mid-elevation primary forest to the north of the Congo River, from southeast Nigeria to western DRC ( Channing and Rödel 2019). The specimens reported here are the first records for Cabinda Province and Angola ( Baptista 2024) and represent the southernmost records for the species. Both specimens collected were found foraging on the ground at the edge of a dirt road surrounded by primary rainforest in Lower Mayombe, at ∼ 200 m a.s.l.
