Summary:
A dwarf tongue sole known from a single male specimen collected in 1892 on the Holothuria Banks in the Timor Sea, off north Western Australia. The anterior margin of the upper eye is noticeably in advance of the anterior margin of the lower eye, and there is a well-developed fleshy ridge on the posterior part of the ocular-side lower jaw.
