Abstract

Eleven philopotamid caddisfly species in the genus Hydrobiosella Tillyard are newly described from Australia, based on small differences in features of the male genitalia. These species are placed in two new species groups, one based on H. letti Korboot, the other on H. bandabanda sp. nov.

The five species of the Hydrobiosella bandabanda group, all newly described here: H. bandabanda, H. jibboor, H. jirrima, H. tarrong and H. tiarka, share features of phallus with two or more embedded spines subapically and both preanal appendages and parameres absent. Females of four of these species are also figured in part. All five species are endemic to the eastern half of Victoria, mainland Australia.The H. letti species group comprises seven species: Hydrobiosella bifurca, H. bos, H. excilatas, H. fibra, H. incisura, H. letti Korboot and H. tenuitas, united in having features such as elongate, nearly straight parameres arising near middle to base of phallus, no obvious spines in phallus and presence of preanal appendages. Females of two of these species are also partly figured. These seven species are all are endemic to eastern coastal mainland Australia, from northeastern Victoria to eastern Queensland.
