Endophytus

This is a genus with only one known species globally, found in the Palaearctic. The species occurs in Britain but is absent from Ireland.

The species is under 4mm in size. Venation can be inconsistent. However, in the forewing, the intercostal cross vein Sc meets vein R basal to where vein M does. Vein 2r-rs is normally present in the marginal cell. The basal loop of the anal cell is normally complete. Vein 2r-m is often absent but if it is present then vein 1m-cu meets cell 1RS and vein 2m-cu meets cell 2RS. Vein 2m-cu can be present or absent.
