Introduction

This is the most species-rich genus of the subfamiliy Eurymelinae with ten species ranging from the tiny E. minutum Evans at 5 mm to the large, colourful E. pulchra (Signoret) at 11 mm. Some species are very common and widespread, e.g. the highly variable E. punctata (Signoret) which is found in all states of Australia except the Northern Territory and is also recorded from Papua New Guinea. Kirkaldy (1906) and Evans (1933) noted that Ashmead (1899), in establishing the generic name, did not assign any species to it and the genus was not validated until Kirkaldy (1906) described a number of new species and provided a checklist of species, indicating that E. bicincta (Erichson) was the type species, although the species was unknown to him. Two syntypes of Eurymelia bicincta Evans were located in Berlin by M.M. Stevens in 1991 and these were found not to be E. bicincta as recognised by Kirkaldy (1906) and Evans (1933) but were actually the species known as Platyeurymela semifascia (Walker). An application to the ICZN (Stevens & Fletcher 1991) to have these specimens set aside as syntypes of E. bicincta was successful (ICZN Opinion 1706, 1993) and a male specimen in the BPB, which was a syntype of Eurymeloides bicinctellus Kirkaldy, a synonym of E. bicinctus, sensu Evans, was established as the neotype for E. bicinctus (Erichson).

Diagnosis

Posterior tibiae with a double row of very weak spines (Ashmead 1889).

The head in profile is slighly convexly rounded, in some species almost flat, and the vertex seen from above is angular. The tegmen has distinct apical cells and a well developed appendix. The hind tibiae have three to five distinct spurs decreasing in size from the apex of the tibia to the base. The male genitalia have large, broad subgenital plates with distinct curved styles that lie along the ventral external margin of the plates but are not covered by them. The aedeagus invariably has one or two spines on the side of the posterior edge and no anterior ventral process (Evans 1933).
