Two faronite genera,
In the initial steps of revising the Australian faronite fauna, which includes numerous undescribed species (
Thirty-six specimens were examined from the
Members of this genus are easily separated from other faronite genera by the following combination of characters: rostrum separated by distinct frontal sulcus (Fig.

Both sexes of this species have the hind wings approximately half normal size when compared to the other species. However, four specimens were collected by flight intercept trap, so we speculate that this species still has the ability to fly.
