Enithares buhleri occurs syntopically with E. timorensis throughout the island of Timor, but in the experience of the author is generally less abundant at any given site. It may be easily separated from E. timorensis by its rounded and spatulate metaxiphus, which assists in sorting mixed series of the two taxa. It is also generally larger-sized and darker colored than E. timorensis . The typical habitat for both species is upland pools along springfed streamlets emerging from limestone bedrock.
