Olive Striped Frog

morphology

Vomerine teeth are in two small groups just behing the level of the choanae. Head is slightly broader than long; snout is rounded, as long as the diameter of the eye. Interorbital space is as broad as the upper eyelid. Tympanum is two fifths the diameter of the eye. Fingers are rather long, free, with large disks (as large as the tympanum). Toes are half webbed, and discs are slightly smaller than those of the fingers. The inner metatarsal tubercle is small, oval in shape and feebly prominent. The tibio-tarsal articulation reaches the eye. Skin is smooth on dorsum and granular on the belly and under the thighs. Dorsum is brown with or without small black spots. Groin is marbled with black and yellow. Upper surface of arm and thigh, and inner surface of tibia are more or less regularly barred with black and yellow. Venter is brownish in color. Males exhibit two black external gular vocal sacs, and a small gular disk between them (Boulenger, 1906).

discussion

COMMENTS. — There is a second described species of Phlyctimantis inhabiting west-central Africa, namely Phlyctimantis boulengeri Perret, 1986 (Type locality: “ Fainchang, région de Mamfe, Cameroon occidental ”), considered as a subspecies of P. leonardi by some authors (Amiet 2012; Amiet and Goutte 2017). The identity of several populations from west and central-western Africa remains problematic (Amiet 2007; Köhler et al. 2005). Although there are records identified as P. leonardi from Bioko and Río Muni, the taxonomic allocation of both mainland and insular populations needs to be revised. Köhler et al. (2005) suggested that several populations from Cameroon, Gabon, Equatorial Guinea and Democratic Republic of Congo probably belong to P. boulengeri. Bosch et al. (2000) provided a call spectrogram of putative Phlyctimantis leonardi from Bome, Río Muni, which are highly similar to those of P. boulengeri from Barrage de Tchimbélé, Gabon (Köhler et al. 2005). However, both species names (P. boulengeri and P. leonardi) are likely representing still more undescribed species (Köhler et al. 2005; Amiet 2007; Onadeko and Rödel 2009). The specimen in the EBD collection came from Bata regio
