  Type species:

   Austrorgerius collinus Woodward, 1960 by original designation.

Introduction

This genus is monotypic and only known from a single locality in SE Queensland. Its placement in the Orgeriinae by Woodward (1960) has been questioned by Emeljanov (pers. comm. 2005) and it might be more appropriately placed in the Dictyopharinae: Cleotychini.

Diagnosis

Body oval. Head subtriangular, at least twice as long as eye, about two thirds as wide as pronotum posteriorly. Eyes contiguous with pronotum, the anterior margin of which is excavated on each side to receive them. No callosity behind eye. Crown horizontal, broad, more than two thirds as wide at base as long, produced in front of eyes for more than one half its length; median carina distinct except at apex, on the same plane a distinct submedian carina on each side; lateral margins carinate but not laminately expanded, upcurved, parallel along medial margins of eyes, thence anteriorly convergent. Anterior part of frons very strongly and carinately convex, so that, in lateral view, head process (in front of eyes) strongly sloping in to mid-ventral line, not bent or curved, longer than deep, narrowing to rounded apex. Central tablet of frons broad in middle between eyes, gradually narrowed anteriorly and posteriorly; in front widely separated at junctions with vertex. Lateral compartments of frons without obvious large pores, of similar granular appearance to that of central tablet; laterofrontal carinae angulate at anterior margin of eye, anteriorly obsolete, not reaching margin of crown. Clypeus without a median carina. Apical plate of head (seen from in front) very small, triangular. Antennae with pedicel reaching to or a little beyond outer margin of eye; flagellum about twice as long as eye. Rostrum reaching to hind coxae. Pronotum transverse, not greatly narrowed anteriorly; whole surface finely pitted; anterior margin nearly straight except where excavated behind eyes; posterior margin broadly and shallowly excavated; lateral margins carinate; median carinae present; a central tablet demarcated by two carinae in line with lateral margins of crown. Mesoscutellum longer than pronotum, finely pitted, with a well developed median carina and weaker lateral carinae. Tegulae absent. Tegmina brachypterous, apical margins nearly transverse; five longitudinal raised veins with a series of segmental carinae and two other series on each side. Legs very short, stout; all femora and front and middle tibiae moderately compressed, with edges somewhat produced but not laminately expanded; hind tibiae with two lateral spines, one near base, one at about half-length.
