Abstract

A new species group of Euops Schoenherr is described from the highlands of New Guinea and is referred to as the 'spinosus-group'. The included species can be readily identified by the conspicuous spines on the posterior part of the elytral humeri. The group contains ten new species : E. aculeatus sp. n., E. armatus sp. n., E. gressitti sp. n., E. monstruosus sp. n., E. paniaiensis sp. n., E. paraspinosus sp. n., E. pseudomonstruosus sp. n., E. spinosus sp. n., E. yali sp. n., and E. zimmermanni sp. n. The species are described and the characters relevant for their identification, including male and female genitalia, are illustrated. A key to the species is provided. A cladistic analysis is performed, and the monophyly of the group is demonstrated.
