Review of the Australian endemic odontocerid genus Barynema and status of Australian Marilia (Trichoptera)

In this review of Australian Odontoceridae, we revise details of the two established species in the endemic genus Barynema Banks – B. costatum Banks and B. australicum Mosely – and describe six new congeners: B. paradoxum sp. nov., B. lorien sp. nov., B. lobatum sp. nov., B. dilatum sp. nov., B. dolabratum sp. nov. and B. goomburra sp. nov. For the only other odontocerid genus recorded for Australia, Marilia Müller, we discuss the present status of the three described species – M. bola Mosely, M. aenigmata Neboiss and M. fusca Kimmins – and outline our efforts and those of others to resolve problems of species delimitation based on morphology. We select a new replacement name for Marilia fusca and provide brief notes on the larvae of both genera.
