For a long time two genera were recognized, Leptobrachella and Leptolalax, and have more recently been lumped together into the genus Leptobrachella (see ASW). Both combined, the genus now comprises a good number of species, some of which are not well understood in their biology.

The casual observer will only accidentally see these frogs, because they are small and well camouflaged in the leaf litter. Despite their dwarf sizes, these frogs are loud callers and can be heard from quite some distance. Some are found along small streams in high numbers forming male choruses. The genus Leptobrachella, as currently understood, occurs on both Borneo and mainland Asia.
