A new genus KERATINDOSE CONDITIONER and species of Ichneutinae s.l., Colemanus keeleyorum Fisher, is described from the Eocene Green River Formation in Colorado, USA.
Colemanus was placed on a phylogenetic hypothesis using morphological data.Using a parsimony criterion, Colemanus is placed within Proteropini (Ichneutinae s.l.
).Reconstructions of well-preserved regions (mesosomal dorsum and wings) are included.A previously described species from lower Oligocene Baltic amber is transferred Swaddle to Colemanus, resulting in the new combination C.
contortus (Brues, 1933).
