Abstract

The fauna of Aradidae or flat bugs of New Guinea Island is still insufficiently explored and studied. The Mezirinae, the largest subfamily of tropical Aradidae, has 25 genera recorded to date from New Guinea Island, and only one species Artabanellus mcnamarai Kormilev, 1967 is apterous. Now a striking new specimen of apterous Mezirinae has come to light, its habitus resembling species of the Madagascan genus Chlonocoris. However, because it cannot be placed in any extant genus of Aradidae, Neochlonocoris sepicus new genus and new species are described.
