Introduction

The Australian endemic genus Rosopaella is the most species-rich genus of Australian Idiocerinae with 31 species recognised by Webb (1983) distributed over most parts of the continent and Tasmania. Some of the species are distinctively marked but many are plain. The genus includes some of the most common and widespread idiocerines in Australia and there may be additional species awaiting discovery. Webb (1983) indicates for several species that additional specimens are tentatively assigned to those species but exhibit some variation in colour or even male genitalia. All species of Rosopaella are united in the structures of their male genitalia which provide the most useful means of identifying the species. Females can usually only be identified if they belong to species with a distinctive colour pattern.

Diagnosis

Webb (1983) provided a comprehensive description of the genus and keys to species based on known males and females.

The genus is very similar to Zaletta Metcalf and Balocerus Freytag & Morrison but differs externally in having the laterofrontal sutures directed towards and reaching or nearly reaching the corresponding ocellus, and in the male genitalia by the posterior margins of the pygophore being lobe-like slightly dorsad of midpoint, the subgenital plates having marginal setae only dorsally and usually a ventroapical heel, the apical process of the style being curved basally and the aedeagus usually having a dorsoposterior neck (Webb 1983).
