}}Leptopelis ragazzii is a species of frog in the family Arthroleptidae. It is endemic to the Ethiopian Highlands on both sides of the Great Rift Valley.[1][2][ Common names Ragazzi's tree frog and Shoa forest treefrog have been coined for it.[2][7] It is named after Dr. Vincenzo Ragazzi (1856–1929), from the Modena Natural History Society, who explored and collected in Ethiopia.[7]]DescriptionAdult males measure {{convert|28|-|43|mm|abbr=on}} and adult females {{convert|39|-|50|mm|abbr=on}} in snout–vent length. There are two colour phases. In phase A, the dorsum is pale greenish-yellow, bright green, or dark olive, and typically there are no darker markings. In phase B, the dorsum is cream, pale grey, or greenish to dark red-brown. There is a feeble to very pronounced pattern of grey or green to dark brown or black blotches, spots and freckling. These markings form a more or less discernible triangle or rectangle. A series of irregular blotches is usually present in the sacral region. Limbs have transverse bars that may or may not be well-defined. Few to numerous cream to bright yellow spots may be irregularly scattered over dorsum. There is almaost always a distinct pale line above vent and heel. The venter is white or cream and usually has a pattern that range from light, pale grey mottling to being heavily blotched or even completely suffused with dark purplish-brown. The male advertisement call is a rather sharp "click", sometimes preceded by a low scream or creaking sound. Habitat and conservationLeptopelis vannutellii lives in montane forest at elevations of {{convert|1900|–|3100|m|abbr=on}} above sea level. It is an arboreal species.[1][ It has also been found near human settlements, and it seems to be able to survive in isolated forest remnants and moderately degraded habitats.[1] The males call from low vegetation near streams, although not necessarily particularly close to water, typically perched some {{convert|0.25|–|2|m|abbr=on}} above the ground.][ The eggs are laid in nests on land, near water, and the tadpoles develop in pools and small streams, both permanent and temporary.[1]Habitat loss caused by forest clearance, human settlement, and encroachment by subsistence agriculture is a threat to it. It occurs in the Bale Mountains National Park, although this offers limited protection only. Chytrid fungus has been detected in this species, although its impact remains unknown.[1]]References1. ^1 2 3 4 5 {{cite journal | author = IUCN SSC Amphibian Specialist Group | title = Leptopelis ragazzii | journal = IUCN Red List of Threatened Species | volume= 2013 | page = e.T56279A16947831 | year = 2013 | doi = 10.2305/IUCN.UK.2013-1.RLTS.T56279A16947831.en }}
