DESCRIPTION. — 2 specimens studied. Ptychadena with a compact and less slender body than P. pumilio . Limbs comparatively short; webbing formula: I 1 - 1½ II 0 - 2 III 1 - 2 ½ IV 2 ½ - 0 V. Absence of supernumerary tubercles. The back with discontinuous, partly indistinct rows of elongate warts ( Fig. 6D View FIG ; Fig. 8A View FIG ). A discontinuous white lateral line, extending from above the tympanum to the rear back. Dorsal colour greyish with some darker spots.

COMMENTS. — Specimens identification based on the discontinuous dorsal ridges and their size (see Nago et al. 2006). However, in other parts of Africa, this name is applied to frogs which look completely different (larger and showing continuous dorsal ridges): see e.g. Channing (2001). Werner (1908) indicated in the original description a size ranging from 35-43 mm for the four females from Sudan.

HABITAT. — The two males were captured on the edge of a small water body in the floodplain from Arly National Park. Ptychadena schillukorum inhabits dry savannahs and grasslands ( Nago et al. 2006; Sánchez-Vialas et al. 2017) and it breeds in swampy valleys and savannah ponds during the rainy season ( Nago et al. 2009). The species, as currently defined, is found across sub-Saharan savannahs of West and East Africa ( Stewart 1967; Hughes 1988; Channing 2001; Mohneke et al. 2011; Sow et al. 2017).
