A very small frog (males 23-24,5 mm.) translucent green from the dense forest in Western Cameroun. This species is only known from a single locality at the time of its description. It differs from the very similar A. obstetricans by the smaller size, by its absence of fringes along the limbs and the lack of spinosities in males.

Colour in life: Dorsum light green, by night entirely so or with small dark spots, by day with small white points. Ventrum transluscent greenish with an opaque white breast.

Voice: A click similar to that of Hyperolius concolor
