In Comoe National Park the savanna inhabiting frog Phrynobatrachus francisci (BOULENGER, 1912) changes its habitats during the dry season. While living at ponds in the wet season, it can be traced only at the border of the river in the dry season. There it is only active during nighttime and within a few centimeters from open water. Habitat selection and activity time seem to be results of higher humidity. Analysis of excrements and dissected frogs as well as selected food choise experiments indicate that P. francisci is an opportunistic feeder. Although females have fully developed eggs, at the end of the dry season, reproduction did not occur in the remaining water bodies of river Comoe.

We describe a new species of Phrynobatrachus from the Western part of the Upper Guinean rain forest, West Africa. Phrynobatrachus phyllophilus sp. nov. differs from all other known West African Phrynobatrachus by a combination of morphological and acoustical characters. It is most similar to Phrynobatrachus guineensis from which P. phyllophilus is distinguished by its almost white belly, presence of only one dark bar on femur and tibia, shape of the thumb in reproductive males, advertisement call, reproductive mode, and selection of different forest types. Phrynobatrachus phyllophilus is the first known species of the genus that deposits small clutches of eggs rich in yolk on leaves, in close vicinity to extremely small puddles on the forest floor. Its preferred habitats are swampy areas of primary rain forest. We also describe the tadpole of P. phyllophilus and the advertisement call of P. guineensis.

Phrynobatrachus maculiventris Guibe \& Lamotte, 1958 is a valid species. Herein we clarify its taxonomic status, re-describe it, and provide the first description of its tadpole. The tadpoles\’ specific identity was assessed through DNA barcoding. Phrynobatrachus maculiventris adults differ from all other West African Phrynobatrachus species by a combination of smooth dorsal skin and a peculiar ventral colouration. The analysis of mitochondrial 16S rRNA revealed that R maculiventris differs from other West African species of the genus by at least 4.7\% genetic differences. Their tadpoles are unmistakable due to their aposematic black and yellow colour pattern. Cordioglossa liberiensis Barbour \& Loveridge, 1927 is a synonym of P maculiventris. Phrynobatrachus maculiventris has priority over C. liberiensis as the genus Phrynobatrachus has a species named P. liberiensis Barbour \& Loveridge, 1927, that was described earlier than C. liberiensis.
