STRIPED “RANID" Indirana sp. (WG021)
This frog was found at all the sampling sites except six. It was uncommon/not heard calling at all sites except Sites 4 and 5, where Limnonectes 1 was replaced by Limnonectes 2. It was found on grassy banks and in very small streams beside abandoned paddies. The striped ranid was distinguished from Limnonectes by its smaller size and longitudinal ridges down its back, at least two of which were white. Mean mass of 12 adult males was 1.6g (+/-0.5).
