The skin of these frogs is smooth or finely granulate above, with a narrow glandular lateral fold. While the dorsal regions are brown coloured, the loreal and temporal regions, and sometimes also the sides of the body are dark brown in colour. A white labial band can also be seen. Its limbs have dark cross bands. The ventral parts are typically white, with the throat and breast more or less speckled with brown spots. Males have internal vocal sacs and oval flat glands on the inner side of their arms. Males also have a strong pad on the inner side of the first finger, covered during the breeding season with a greyish brown velvet-like horny layer.
