Revision or Synopsis: N/A

Composition: 8 species.

Taxonomy: N/A

The genus Psilodon has been characterized as possessing a 6-segmented antennal club, as opposed to the 7-segmented club of species of the Australasian genus Syndesus MacLeay. However, at least one species of Psilodon (P. gilberti Boucher) has a 7-segmented club, and at least one species of Syndesus (S. cancellatus Montrouzier) has a 6-segmented club. Regardless, given that no other genera are shared between the two regions and the extremely long period (~55 MY) for which they have been isolated, it is probable that Psilodon should retain generic status and that the appropriate generic characters have not yet been identified.
