Comprehensive DescriptionRead full entry
Leptophryne borbonica is a small toad with a slender body, long legs, and wrinkled skin. Females of this species are typically larger (25-40 mm SVL) than the males (20-30 mm SVL). The snout is short and tapered and projects slightly over the lower jaw. There is no distinct parotoid gland. A slight ridge runs dorsolaterally. Fingers and toes are rounded and blunt. The genus Leptophryne is characterized by a large and oval-shaped first subarticular tubercle on each toe. Toes are webbed at the base; for the third and fifth toes, the webbing does not reach as far as the last subarticular tubercle. True to its common name, it has a black hourglass or X figure on its back. Some members of this species also exhibit a black triangular marking behind the eyes. This toad is grayish brown in color dorsally; its throat and chest are brown, with the belly and ventral surfaces of the legs being gray to yellowish (Iskandar, 1998; Inger and Stuebing, 2005).
The tadpoles are completely black. The lower lips and the sides of the upper lips have papillae. The denticle formula is 2-2/III (Iskandar, 1998).
This species is toxic. Skin extracts had an unpleasant burning taste, and dosesof 100 mg/mouse produced the following effects: locomotor difficulties,prostration, and recovery after 2 hours (Daly et al., 2004).
