  Type species:

   Acanthucus iasis Kirkaldy, 1907 by original designation.

 

Introduction

This endemic genus is currently monotypic and restricted to Queensland and New South Wales. Day (1999) recognised an additional two undescribed species from far north Queensland and queried Kirkaldy's (1907) record of E. iasis from Sydney. However, specimens of the species are known from western New South Wales as well. The genus needs a species level revision to describe the new species and assess the identities of the material from New South Wales.

Diagnosis

The face of the head is almost flat and the eyes are prominent and visible from above. The pronotum, anteriorly, is vertical and in alignment with the face and has a median ridge which extends from the anterior margin to the posterior apex. The anterior margins of the oblique lateral processes are at right angles to the median ridge; they have three distinct sides and on the dorsal surface are apically depressed beetween the marginal ridges. The posterior process extends almost as far as the apices of the folded tegmina. The tegmina are apically acute, M and Cu1 are fused proximally for a third of their lengths, m–cu3 is the only crossvein between them and all four apical veins are parallel with the hind margin of the tegmen distal of the apex of the clavus (Evans 1966, as Kurandella).

Clypeus short. M and Cu fused for almost one third of their length, an unusual condition. m–cu3 absent or very short. MPP reaching apex of tegmen. Markedly setose, with setae on surface of tegmen (Day 1999).

Day (1999) provided a comprehensive redescription of the genus.
