Limnonectes hikidai is one of the several similar-looking Bornean frogs that have been distinguished from the rest of the Limnonectes “kuhlii” species complex. Compared to the others in this part of Borneo, these frogs are smaller, live in calmer water, and have less-fully-webbed toes.

I'm basing my IDs here mostly on the toe webbing, and I'm not very confident.
