Rhinella scitula is a species of toads in the family Bufonidae. It is found in the southwestern Mato Grosso do Sul, Brazil, and in the adjacent southeastern Paraguay (Amambay and Concepción Departments).[3][4]
Description
[edit]Males measure 33–46 mm (1.3–1.8 in) and females 46–51 mm (1.8–2.0 in) in snout–vent length.[2][4] The species has a robust appearance. The snout is rounded with a small apical apophysis in dorsal view and sub-acuminate in lateral profile. The coloration is variable. The dorsum is generally light brown to dark brown. Light-colored individuals have no pattern or have a cream vertebral line. Darker specimens have a broadish, light brown vertebral stripe. There is a black, triangular inter-ocular spot facing backward, as well as an oblong dorsal blackish spot that connects to another black spot near the urostyle. The belly is light creamy, marbled with light gray.[2]
Habitat and conservation
[edit]Rhinella scitula is associated with seasonal forests and mountainous landscapes at elevations between 100–700 m (330–2,300 ft) above sea level.[3][4] Breeding takes place in small pools in slow-flowing streams[1] after rainfalls and is of explosive type. Males call mainly during twilight.[2][4] The species is abundant in seasonal forest areas with rocky outcrops.[4] As of 2004, no threats to this then recently described species had been identified.[1]
