Diagnostic Description

This is a very small brown frog with variable markings. It usually exhibits a light triangle on the snout and darker diamonds on the dorsum. The tympanum is visible and approximately ½ the diameter of the eye in adults. The diameter of the eye is roughly the same as the distance from the eye to the tip of the snout. The nostrils are closer to the tip of the snout than to the eyes. Toes and fingers are distinctly swollen, with round disks on the fingers and on the 3rd, 4th and 5th toes. Toe disks are slightly oval rather than round. The toes lack webbing. In males the 3rd finger can be as much as 3.5 times the length of the 4th finger (Text from Harper et al., 2010).

Comparisons

This species is similar to A. xenodactylus and A. xenodactyloides but the head is not distinctly wedge-shaped as in A. xenodactylus, and A. stridens lacks the papillate toe tips seen in A. xenodactyloides (Harper et al., 2010).

Pickersgill (2007) describes the call as “musical, high-pitched and insect-like” in comparison to the more rasping call of A. xenodactyloides.
