Diagnosis. Emesopsis in Australia can be recognised by the following combination of characters: head, thorax and basal abdominal sternite densely clothed in wool-like pile; darkened areas of wings sometimes raised, with unpigmented pits, M and Cu separate at base of truncate discal cell; 2nd segment of rostrum distinctly swollen.

Remarks. This genus was previously diagnosed by the presence of a small subquadrate basal cell, however, this character is now known to be absent in one mainland Australian species, Emesopsis infenestra ( Tatarnic et al. 2011) , as well as the new Lord Howe Island species E. cirratus , described herein. This latter species is the sole member of the genus to be found on Lord Howe, and is distinguished by slight wing reduction, with the apex of the hemelytra distinctly upturned.
