DESCRIPTION
. — Slender-bodied tree frog (SVL
22.5-23.7 mm

). Tympanum poorly distinct (TYD 3-5%
SVL
). Tibia moderately long (TL 46-50%

1 ½ – ½ V. Toes and fingers terminated by discs. Skin uniformly smooth over entire back and flanks; belly and chest granular.
COLOURATION
. — The dorsal colouration is characterised by a dark mid-dorsal band that includes the inter-orbital band and a sacral spot; in other individuals three large, transversely orientated spots, an inter-orbital, a shoulder and a sacral spot, form the dorsal pattern. The ventral side is white.
SEXUAL
DIMORPHISM
. — The male has a subgular vocal sac with a gland.
HABITATS
AND
DISTRIBUTION
. — The small number of specimens collected makes it difficult to estimate the species range in
Togo
. The specimen MNHN-RA-2008.0129 was captured in the gallery forest along the Yégué River in Adélé (
Hillers
et al.
2009
).
SchiØtz (1999)
indicated that it is mainly a forest species. The distribution localities mentioned in the Volta region between
Togo
and
Ghana
(
Rödel & Agyei 2003
) confirm the range of this species.
