Introduction

There are just three species of Euacanthella all of which are elongate, seed-like species associated with grassland or pasture. One species was recently described from Barrow Island and Lorna Glen Station in Western Australia and the other two are found in southeastern Australia (New South Wales and Tasmania) with one also occurring in New Zealand.

Diagnosis

The head is arrow-shaped, the anteclypeus much narrower anteriorly than posteriorly, the antennal scrobes distinct but short and the antennal pits deep. The crown of the head, which is slightly tilted dorsally at the apex, has a slight depression anteriorly, has always a coronal suture and may have a transverse epicranial suture. The ocelli are on the crown, well away from the anterior margin. The pronotum is much narrower than the head, including the eyes, and the propleurae narrowly separate the eyes from the bases of the tegmina. The scutellum is small. Both brachypterous and fully winged forms occur and the tegmina of the winged forms are narrow (Evans 1938).
