DESCRIPTION. — Slender frog (SVL 25.7-29.5 mm ♂, 30.4- 32.5 mm ♀). Snout slightly rounded. Head slightly longer than broad (HW 26-35% SVL; HL 32-38% SVL). Tympanum barely distinct, covered by skin (TYD 2-4% SVL). Hind leg moderately long (TL 47-50% SVL). Webbing moderately large, leaving up to two phalanges free; webbing formula I 1 – 1 ½ II ½ – 2 III ½ – 2 IV 1 ½ – ½ V. Fingers and toes terminated by discs. Skin smooth on the back, head and flanks; chest and belly granular.

The loreal and tympanic regions are black with small white or yellow dots. The posterior surface of the thighs is reddish or pink. The ventral side has a whitish colouration.

SEXUAL DIMORPHISM. — Males with gland on subgular vocal sac. Females are distinctly larger than males.

HABITATS AND DISTRIBUTION. — Originally, the species was collected in Missahohé (Kpalimé), forest area of Togo ( Ahl 1931). This species is endemic to the Togo-Ghana forest zone according to SchiØtz (1999), Rödel & Agyei (2003) and Leaché et al. (2006). It is very abundant throughout the forest area of Togo. It occurs likewise in savannahs associated with forest areas near watercourses or pools. Males are usually sitting on grasses ( Panicum sp. ) at heights of 1.5 to 3 m above the ground, usually above water. This species was observed from the lower Missahohé Mountain (Yo, Agome) to Yégué in Adélé. The northernmost record in Togo is from Malfakassa valley (9°10’45.54”N, 0°58’16.69”E).
