Description
M 40-45 mm, F 40-45 mm. Weakly expressed outer dorsolateral folds, no inner dorsolateral folds, interocular tubercles, supraocular spines, nor heel tubercles. Dorsal skin smooth. Colouration variable but most individuals with a distinct light stripe along the upper lip.

Similar species: Gephyromantis redimitus and G. cornutus also call along brooks in forest, but have single subgular vocal sacs and mostly two black tubercles between the eyes. Tibiotarsal articulation of G. redimitus reaches only beyond the eye. G. leucomaculatus has a smaller inner metatarsal tubercle, lacks the light band along the upper lip, and calling males are not found along brooks. It is especially similar to G. zavona.

It occurs from near sea level up to 900m (Raxworthy and Vences 2008).

Life History, Abundance, Activity, and Special Behaviors
Habits: Males call at night from the vegetation, 0.5-2 m above the ground, close to streams. In intact and degraded rainforest as well as in secondary vegetation.

Calls: A long regular series of unharmonious notes.

Trends and Threats
This species is listed as least concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category (Raxworthy and Vences 2008).
