  Type species:

   Australoscopus whitei China, 1926 by original designation.

 

Introduction

The single species in this genus is known from widely scattered localities across Australia. Day & Pullen (1999) report that a species identified as Australoscopus was observed at Waikerie, South Australia, in association with Camponotus terebrans (Lowne), being carried by its host ants when danger threatened. The ants lifted the leafhoppers upside down in order to carry them deeper into the nest.

Diagnosis

Similar to Pogonoscopus Ch. in the rounded vertex and face but differing in the narrower and more deflexed head, the tyep of structure of the last ventrite and the armature of the hind tibiae. The anterior margin of the pronotum is reflexed but not regularly, a small median section being muich less elevated. The reflexed anterior pronotal margin instead of meeting the posterior margin of the vertex, projects beyond the vertex so that the head is sunk beneath it. The breadth between the posterior margin of the eyes and that of the vertex is much greater than that in Pogonoscopus and Lasioscopus. The penultimate rostral joint extends beyond the apices of the hind coxae. Owing to the reflexed anterior pronotal margin extending beyond the posterior margin of the vertex, the pronotum from above appears to be produced anteriorly between the eyes much more than in Pogonoscopus. The tegminal and wing venation is similar to that in the latter genus but the armature of the hind tibiae is more dense, with much denser and longer hairs interspersed with the spines. The last ventrite in the ♀ instead of being indented medianly as in the two preceding genera, is produced into a tongue-like process in the centre (China 1926).
