Olethreutes trinitana
(McDunnough, 1931)

The species is known from scattered records across central and eastern North America, primarily from the Canadian prairie provinces and northern New England. Like other members of the Olethreutinae , it is presumed to have a concealed larval stage, though specific biological details remain poorly documented. The Olethreutes is diverse, with many species requiring dissection or molecular analysis for reliable identification.

Taxonomic history
Originally described as Argyroploce trinitana by McDunnough in 1931, later transferred to Olethreutes. The specific epithet 'trinitana' likely refers to the locality, though this is not confirmed in accessible sources.
