Vanzolini's leaf frog
Phrynomedusa vanzolinii, or Vanzolini's leaf frog, is a frog in the family Phyllomedusidae. It is endemic to southeastern Brazil where it is currently known from Teresópolis in the state of Rio de Janeiro and Boraceia in the state of São Paulo, Brazil. It probably occurs more widely than current records suggest, especially in areas between the two known sites. It is possible that this species is a synonym of Phrynomedusa appendiculata.
The specific name vanzolinii honors Paulo Vanzolini, a Brazilian herpetologist and composer.
Adult males measure 33–35 mm (1.3–1.4 in) and females—based on the only known specimen—36.5 mm (1.44 in) in snout–vent length. The body is slender. The tympanum is visible. Skin on dorsum and limbs is smooth. The webbing between fingers and toes is reduced. The upper surfaces are green or violet brown. There is a narrow, oblique orange stripe running from the posterior border of eye to the arm insertion. The venter is immaculate.
