Emesopsis Uhler 1893 

Diagnosis. Recognized in Australia by the following combination of characters: head, thorax and S 1 covered in dense wool-like pile; darkened areas of wings pitted with unpigmented dots, M and Cu separate at base of truncate discal cell; 2 nd segment of rostrum distinctly swollen

Remarks. Emesopsis  is probably the most morphologically diverse genus in the tribe. The genus has previously been diagnosed by the presence of a small subquadrate basal cell, however, this character is not present in one Australian species, Emesopsis infenestra  , nor in an undescribed species from Lord Howe Island. Though these species lack a basal cell, they are otherwise clearly members of the genus. Furthermore, the basal cell has been found to be present in one wing and absent in the other within a specimen of E. fenestrella  . The loss of the basal cell could result from the migration of the Cu and discal cell towards one another. This transformation of a large cell to small, and then obsolete subquadrate cell can be visualized by examining the wings of E. fenestrella  , E. bunda  and E. infenestra  respectively.
