Sphaenorhynchus orophilus, or Lutz's lime treefrog, is a species of frog in the family Hylidae. It is endemic to southeastern Brazil where it occurs in the Serra do Mar and Serra da Mantiqueira ranges in the states of Rio de Janeiro, São Paulo, and Minas Gerais.[1][2][3] However, Araujo-Vieira and colleagues suggests that the Serra da Mantiqueira population could represent Sphaenorhynchus canga; the two species are similar.[4]

Description

Adult males measure 29–32 mm (1.1–1.3 in) in snout–vent length. The snout is pointed or truncate-subovoid from above and acute in the lateral profile. The finger and toe tips bears discs; both the fingers and toes are moderately webbed. The dorsum is green. Black mottling or spots may or may not be present. The dorsolateral stripes are yellow above and black below. The ventrum is green or greenish yellow. Males have a single vocal sac.[5]

Habitat and conservation

Sphaenorhynchus orophilus lives on vegetation above large ponds or lakes or at the edge of forests. Breeding takes place in relatively deep permanent ponds and lakes. It is threatened by drainage of its breeding habitat for mosquito control and the application of insecticides to kill mosquitoes. This practice also occurs within protected areas.[1]
