[ its range may extend south to Kenya, perhaps further. Some earlier records from Ethiopia represent '' Phrynobatrachus inexpectatus'', described as a new species in 2001.] The specific name ''minutus'' refers to the small size of this frog. Common names tiny river frog and Ethiopian dwarf puddle frog have been coined for it.[

Description
Adult males measure and adult females in snout–vent length. The tympanum is present but usually hidden, although it may sometimes just visible through the skin. The toes have feeble webbing and may have weakly developed discs. Dorsal skin is smooth or may have warts that can even be prominent, especially on the upper flanks, posterior back, and hind limbs. Alcohol-preserved specimens are dorsally pale to dark grey-brown or yellow-brown. In life, adult males have bright yellow throat.
Habitat and conservation
''Phrynobatrachus minutus'' occurs at the swampy margins of aquatic habitats (lakes, rivers, streams, and temporary pools) in moist grassland and forest clearings at elevations of above sea level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''.
