The adult moths have brown forewings, each with an oblique straight line from near the wingtip to halfway along the hind-margin, and a submarginal row of dark dots. The hindwings are plain brown. The moths have a wingspan of about 2 cms.

Specimens have been taken in

as well as in Australia in

Kollar's 1844 holotype was lost for a period, during which the replacement name Hypena masurialis Guenée, 1854, was suggested. Subsequently the holotype was found, and so now the junior replacement name is no longer necessary.

Rhynchina obliquarlis is superficially very similar to Hypena obacerralis, and they are confused in many collections. We hope we got the above photos correctly identified.
