Abstract
A new megophryid species of Leptobrachium is described on the basis of three specimens collected from Kubu Perahu, Lampung Province, Sumatra, Indonesia. The new species, L. waysepuntiense sp. nov. is distinguished from all other congeners by the colour of iris, which is totally light bluish in adult and greyish in juvenile stages. It is similar to Bornean endemic species in the absence of dark markings around groin, and particularly to L. gunungense in the very small size of femoral gland. It is the fourth species of Leptobrachium recorded from Sumatra, and its discovery underscores the under estimated diversity of amphibians on Sumatra. Variation in the pattern of iris colour in Leptobrachium is discussed.References
