Abstract:
A new dicroglossid frog allied to Bornean Limnonectes kuhlii-like fanged frogs is described from Krayan of East Kalimantan, Indonesia, and Kelabit Highlands of northern Sarawak, East Malaysia based on morphological characteristics. The new species, L. sinuatodorsalis is superficially similar to other Bornean species L. asperatus and L. hikidai in small body size and poorly developed webbing on the fourth toe, but differs from them in several characteristics, especially in dorsal texture. The new species occurs syntopically with Limnonectes cf. kuhlii in both the two known localities, possibly through ecological segregation by large body size difference between them.
