LITERATURE REPORTS. ��� Burkina Faso ��� Gourma province, Fada N���gourma; 12.06051��N, 0.34913��E; 300 m a.s.l.

Stout and robust frogs, with a moderately pointed snout, strong and long limbs. An inner and an external metatarsal tubercle present and very protruding as indicated by R��del (2000) and S��nchez-Vialas et al. (2017). Webbing formula: I 0 - 1 �� II 0 - 1 III 0 - 1 �� IV 1 �� - 0 V. Four pairs of continuous dorsal ridges extending along the entire back. In life and alcohol, dorsal colouration from brown to dark grey. Presence of a wide white, yellow in life, vertebral line in all specimens. Species usually with a more granular dorsal skin, in comparison to other members of this genus (R��del 2000). HABITAT. ��� Specimens were captured in grasses near water bodies in Como��-L��raba Forest and Deux Bal�� National Park; on a trail near a water body in Arly National Park; under humid gasses at Dori pond and Yakouta dam banks. Ptychadena trinodis was one of the most abundant Ptychadena species at savannah ponds during the rainy season (Nago et al. 2006). The species is then virtually restricted to small or tiny water bodies which often lack vegetation (Guib�� & Lamotte 1957; Lamotte 1969; Schi��tz 1967; Perret 1981; R��del 2000). This species is distributed from West Africa east to northern Democratic Republic of Congo (R��del 2000; Padial & De La Riva 2004; S��nchez-Vialas et al. 2017; B��hme & Heath 2018).
