Troschel's treefrog (Boana calcarata), also known as theblue-flanked treefrog[2] or theconvict treefrog,[3] is a species offrog in the familyHylidae.[2] It is found in most parts of theAmazon Basin including Suriname.[1][2][4] Colombian, Guianan and Venezuelan records need confirmation.[2][5]
This species was originallydescribed byFranz Hermann Troschel asHyla calcarata in 1848. AfterEdward Drinker Cope transferred it to the genusHypsiboas asHypsiboas calcaratus in 1867, it was variously recognized with either name until Faivovich and colleagues validatedHypsiboas in 2005. However, in 2017Alain Dubois [fr] showed thatHypsiboas was ajunior synonym ofBoana, the latter then being the valid name.[2] Many sources, however, still use the old name.[1][3]

Adult males measure 28–43 mm (1.1–1.7 in) and adult females 46–56 mm (1.8–2.2 in) in snout–vent length. The fingers have only basal webbing while the toes are webbed. Males have pre-pollical spines. Thedorsal coloration varies from light brown to reddish brown or brown. There is a dark brown middorsal line, and some specimens have brown diffuse transversal bands. The limbs bear pale brown transversal bars dorsally. Scattered minute white and black dots, or large dark brown blotches, might be present on the dorsum. The flanks are white, light blue or blue and have dark brown vertical bars. The venter is creamy white and the belly is yellowish white.[5]
This species occurs in tropical rainforest at elevations up to 1,000 m (3,300 ft)above sea level, but mostly below 400 m (1,300 ft). It is anarboreal frog. During the rainy season, adults can be seen perched on stems and small branches above slow-moving streams. The eggs are deposited in water where the larvae will then develop.Habitat loss associated with forest conversion, logging, clear cutting, and fire is a threat to this species. However, it is abundant in parts of its range, is present in protected areas, and is not threatened overall.[1]
