Ohler leg.; on flooded grasses; hand capture • 5 ♂ ( SVL 30.3-31.7 mm); Comoé-Léraba Forest , Baboro swampy valley; 9.92522°N, – 4.57575°W; 240 m a.s.l.; 4.VIII.2018; same collectors as for preceding; on high, flooded grasses; hand capture • 1♂ ( SVL 29.7 mm); Kou Forest , near the Guinguette water source; 11.18720°N, – 4.44185°W; 340 m a.s.l.; 7.VIII.2018; same collectors as for preceding; on leaves of palm trees; hand capture.

DESCRIPTION. — 10 specimens examined. Only males collected, with SVL 27.8-31.5 mm. Life colouration yellowish to greenish ( Fig. 4D ). Usually during the day, males more brownish to yellow, often with some dark dorsal pattern, whereas females showing a green colouration. At night individuals of both sexes with a yellow colour ( Rödel 2000). In alcohol, specimens whitish with small black spots, visible only with a dissecting microscope.

HABITAT. — Hyperolius concolor concolor was found on flooded grasses in Comoé-Léraba Forest and on palm leaves at the source of the Guinguette River in Kou Forest. Specimens were usually sitting comparatively higher than H. nitidulus , but see Rödel et al. (2006) for calling site position in various West African hyperoliids. The species is known to occur in areas of degraded forests and humid savannah; it extends into drier savannah zones along gallery forests ( SchiØtz 1999; Rödel 2000). It is distributed in West Africa from Sierra Leone to northern Benin ( SchiØtz 1999; Rödel 2000; Nago et al. 2006).
