• Proterosydyne Kirkaldy, 1907 [original spelling; the genus was spelt "Proterosydne" on pages 13, 124 and 126 of Kirkaldy (1907) but "Proterosydyne" on page 130 with the original description. This was taken by most subsequent authors as being a mis-spelling].

Introduction

This endemic genus is represented by a single female specimen from "Queensland". It was collected by Arthur Koebele so was from the eastern coastline either in the Cairns region of North Queensland or around Brisbane in SE Queensland.

Diagnosis

Distinguished by the absence of connecting keels on the vertex, the very large eyes and the peculiar tibial spur.
Vertex subtriangular (the anterior and posterior halves of the lateral margins very obtuse angled, so that, although the vertex is really 5-hedral, it may be said to be triangular), with no median or connecting keels; lateral keels not quite contiguous apically, almost enclosing an elongate exceedingly narrow space before uniting about the apical margin (frontally) of the eyes. Between the apex of the vertex and this forking, the head is highly polished and the keels rather obscure, otherwise the keels are all well marked. The median keel reaches the apical margin of the frons, which is a little emarginate roundedly. Vertex deeply concave, about as long as wide and does not extend as far anteriorly as the eyes, thus displaying a rounded frontal margin. Frons rather narrow, elongate, subparallelsided, slightly rounded exteriorly. Middle keel of genae meets lateral margins of frons at an acute angle at the apical margin of the frons; clypeus rather feebly tricarinate. Head not decumbent on the pronotum anteriolaterally. Eyes very large, about as wide as vertex, longer than wide. Antennae subcylindric, long, reaching almost to apex of clypeus, second segment scarcely more than twice as long as the first, a little wider apically than basally, flagellum much longer than peduncle. Pronotum longer than vertex, narrower apically than the vertex basally, strongly tricarinate, lateral keels straight, reaching posterior margin, not contiguous anteriorly; posterior margin slightly, obtuse-angularly, emarginate posteriorly. Scutellum with anterior three-fourths of disk roundly convex and polished, posterior fourth flat, rather obscurely tricarinate, middle keel not reaching the flat part. Tegmina (brachypterous form only known) granulate, reaching beyond apical margin of last pleurite. Wings rudimentary, reaching very little beyond base of metanotum. Hind tibiae with 2 spines (1 basal), nearly one-half longer than tarsi; spur solid, elongate, narrow, with 8 spines. First segment of hind tarsi longer than the other together. (Kirkaldy 1907)
