see text Paropsisterna is a genus of leaf beetles indigenous to Papua New Guinea and Australia.

[3][4] Paropsisterna are beetles 3-17 mm long with bodies semicircular to elongate-ovate and moderately to strongly convex.

The apical maxillary palpomere is strongly expanded from base to truncate apex.

[5] 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.
