Troschel's treefrog, Blue-flanked treefrog, Convict treefrog
Troschel's treefrog (Boana calcarata ), also known as the blue-flanked treefrog or the convict treefrog, is a species of frog in the family Hylidae. It is found in most parts of the Amazon Basin, except in the southeast and the Guianas. Colombian, Venezuelan, and Surinamese records need confirmation.
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. The dorsal 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.
