Introduction

Metcalf (1947) took Eurystheus inductus Walker as the type species of Rentinus but this was not listed as a species included in the genus Eurystheus originally by Stål (1862). The type species for Eurystheus Stål, a preoccupied name, was established by Distant (1906) as Eurystheus dilatatus (Westwood), with which E. inductus was synonymised by Distant (1906). Why Metcalf (1947) gave priority to Pyrops inductus Walker, 1858, over Fuilgora dilatata Westwood, 1839, is not explained. The genus is endemic in Australia and Lallemand (1963) recognised one species comprising two subspecies. The status of these two subspecies needs to be examined based on male genitalia studies to determine their validity. There are probably undescribed taxa in collections and the relationship between this genus and Eurinopsyche Kirkaldy also needs to be examined.

Diagnosis

Caput longe protuberans, carinis genas a fronte et vertice separantibus undulatis; fronte tricarinata, supra clypeum utrimque leviter rotundato-ampliata, dein sursum angustata; clypeo medio carinato. Thorax basi truncatus, antice pone caput obtuse productus, unicarinatus. Scutellum tricarinatum. Tegmina remote transversim venulosa, venulis discoidalibus ramulos liberos emittentibus, area costali dilatata. Pedes simplices, tibiis posticis quadrispinosis (Stål 1862).

Sur le front, 3 carènes, qui se continuent sur le prolongement; au-dessus du clypéus, il s'élargit et ses bords sont arrondis, puis se rétrécit. Sur le clypéus une carène médiane. Les carènes séparant les joues du front et du vertex sont ondulées. Le pronotum fait saillie vers l'avant, entre les yeux; sur son milieu, une carène longitudinale. Sur le mésonotum, 3 carènes. Sur les élytres, les nervures transversales sont espacées; le tronc commun des 2 nervures du clavus est court et se termine dans le bord sutural; après cette jonction, la suture émet 5 à 6 rameaux obliques rejoignant ce bord avant de s'y souder elle-même. Sur les tibias posterieurs, 4 épines (Lallemand 1963).
