<paragraph pageId="0" pageNumber="77">In life, background color varies from yellowish brown to greyish brown. Dorsal ridges vary in number and definition. In all examined specimens, median ridges were continuous from the back of the head to the groin. Postpalpebral fold usually interrupted in the middle of the back, sometimes continuing on the lower back by a ridge or multiple aligned warts. Short latero-dorsal fold almost always present, sometimes fractioned. Lateral ridges, briefly interrupted in a few specimens, most often continuous, from orange-brown to cream. All specimens examined had small dark brown or black blotches distributed symmetrically on the dorsal ridges, in very few specimens, those blotches were very small or barely visible. All examined individuals have a wide, generally around a lighter thin stripe. The light blotch on the tympanum is generally small and more conspicuous in some specimens than in others. The thin cream longitudinal stripe on the tibia may be more or less conspicuous and extended to half of the thigh in some individuals. Tibias, thighs and feet posteriorly barred with more or less defined brown or light brown markings. Yellow and brown marbling on the posterior side of the thighs more or less contrasted and almost absent in some individuals. Ventrum and throat uniformly white to light yellow. Vocal sacs grey, bicolored cream to yellow and light grey to grey. Small warts over the back and flanks in ca. 10% of adult males examined.</paragraph>

sp. nov. has a wide distribution range extending both sides of the Great Rift Valley, although most records were made west of the GRV (6.14-10.01°N, 35.41-39.27°E). It is restricted to moderate altitudes, from 1695 m to 2596 m a.s.l. (based on 106 barcoded individuals). In the north, its range is limited by the Blue Nile valley and the northernmost specimens have been found just north of Gohatsion. The westernmost population has been found in

<paragraph pageId="0" pageNumber="77">Males are found calling at in shallow roadside puddles or agricultural fields. Males can be found vocalizing very close from one another, sometimes in important numbers. Calling activity depends on rainfall and is highest during rainy months. Calling usually starts after 22:00, and sometimes as late as 02:00 in dry weather, and ceases before dawn. Numerous, small bicolored eggs are laid in the same water body.</paragraph>
