Opisthothylax immaculatus (Boulenger 1903)

Material: One (1) specimen. Mboua: CAS 258235. Fig. 10D .

Comments: This monotypic genus is distinguished from other Hyperoliidae by the combination of its verti- cal pupils, rough skin, and orange color ( Schiøtz 1999). The males have large gular glands and non-descendible vocal sacs ( Schiøtz 1999). This arboreal species builds foam nests ( Amiet 1991). This species was encountered at night on a stem one m above the ground, between a forested stream and an elephant wallow. In Gabon, it is known from Ivindo NP ( Bell et al. 2011) and Rabi-Toucan ( Burger et al. 2006). We sequenced 16S rRNA of this individual and confirmed its identification using BLAST (GenBank accession: MF537682; the most similar Gen- Bank sequence is KX492629; 98% identical).
