Paropsisterna

Paropsisterna is a genus of leaf beetles indigenous to Papua New Guinea and Australia. There are over 120 species, many with bright aposematic colours, and many feeding on Eucalyptus leaves.

The genus was described by Victor Motschulsky in 1860.

Description
Paropsisterna are beetles 3-17 mm long with bodies semicircular to elongate-ovate and moderately to strongly convex. The frontoclypeal suture is rounded or V-shaped, and lacks lateral ridges. The apical maxillary palpomere is strongly expanded from base to truncate apex. The pronotum is broadest at its base. The procoxal cavity is open with a gap at least half the width of the procoxa. The mid and hind tibiae have at least one sharp external longitudinal keel. The tarsal claws are usually acutely toothed, rarely simple.

Some species are very colourful, but their colours may fade after death.

Diet
This genus of beetles feeds on plants in family Myrtaceae, including Acmena, Agonis, Angophora, Baeckea, Callistemon, Darwinia, Eucalyptus, Kunzea, Leptospermum and Melaleuca. There are also records from Acacia (which is in family Fabaceae), but these are likely to be erroneous or related to casual collecting.

Notable species

 * Paropsisterna agricola a pest on Eucalyptus globulus, E. delegatensis and E. dalrympleana

 * Paropsisterna obovata a pest on Eucalyptus in South Australia
 * Paropsisterna selmani a pest on Eucalyptus in Tasmania, introduced to the Republic of Ireland and the United Kingdom.

List of species
As of 2006, Pariosisterna includes the species that were once in genera Niliosoma Motschulsky, Sterromela Weise, Chrysophtharta Weise and Xanthogramma Weise (note the last of these is also a junior homonym of Xanthogramma Schiner, an invalid but available name).
