Araecerus
coffee bean weevil (A. fasciculatus)
Araecerus is a genus of fungus weevils in the family Anthribidae, containing several species including the economically significant coffee bean weevil. The genus includes both described species and multiple undescribed species discovered in Papua New Guinea. Species within this genus are primarily associated with seeds and fruits, with some exhibiting broad polyphagy on stored agricultural products.
Orthostigma
A genus of braconid wasps in the subfamily Alysiinae, established by Ratzeburg in 1844. The genus has been subdivided into multiple subgenera including Whartonstigma and Patrisaspilota, with species described from Europe, Papua New Guinea, and broader Australasia. Taxonomic revisions indicate substantial morphological diversity within the genus, though biological data remain limited.
Paropsisterna
leaf beetles, eucalyptus leaf beetles
Paropsisterna is a genus of chrysomelid leaf beetles containing over 120 species native to Australia and Papua New Guinea. Many species exhibit bright aposematic coloration and feed on Myrtaceae, particularly Eucalyptus. Several species have become invasive pests in New Zealand and Europe, causing significant defoliation of eucalypt plantations and ornamental trees. The genus was redefined in 2006 to include species formerly placed in Chrysophtharta and other genera.
