Introduction

This endemic species is widespread across Australia and has been recorded in all States except Victoria. It is slightly larger than the other species occurring in the country and is often quite pale with the distinctive filigree markings on the tegmina rather obscure. It also often has reddish markings on the head in association with the brown pattern. It has not been associated with disease transmission although it occurs sympatrically with species which are known vectors and it may have vectoring capacity which has not yet been discovered.

Diagnosis

General coloration pale yellow, eyes dark brown, ocelli red. head very pale yellow, crown much wider medially than against the eyes. Pronotum and scutellum apricot yellow. Tegmen hyaline yellowish, extending beyond the apex of the abdomen. Length 3mm (Evans 1938).

This species can be differentiated from all other species of the genus by the short, parallel shafts of the aedeagus in ventral view. Orosius pallidus also has parallel shafts but they are much longer in O. pallidus (more than twice as long as the distance between the shafts) than in O. canberrensis which is also slightly larger than the other species occurring in Australia. Both species are often quite pale with the distinctive filigree markings on the tegmina rather obscure. Orosius canberrensis also often has reddish markings on the head in association with the brown pattern. This species is consistent in male genitalia and in COI sequence data across Australia (Fletcher et al. (2016).
