Genus Xylophion Gauld, 1979

Xylophion may be distinguished from Ophion by the combination of a reduced fore tibial spur flange, forewing with broadened vein Rs+2r and short vein 3rs-m. A particularly striking autapomorphy of the genus is the form of the male tarsal claw ( Fig. 2 ): instead of having a sinuous row of pectinal teeth (as is normal for ophionines), Xylophion males have a marked discontinuity in the centre of the row between the teeth on the apical and basal parts of the claw ( Gauld 1984).
