[4] They are found in Queensland, Australia, along streams and rivers, or near the eastern Australian coast and drainage basins.

The female's genital valves were narrow in measure, with a developed styli and a laterodistal point.

The body measured about 19 mm, its prementum was of a fair width and its ligula and median lobe still were in the process of development.

The specimen's labial palps were still relatively small, but also had six large palpal setae, and its postocular lobe was rather bilobed.

The larvae's pronotal lobe was well developed and included short setae, while its abdomen had obtuse laterodorsal on five segments.
