One described species, Stenoptinea auriferella, is listed for North America. The adult has been collected at light in deciduous forest in mid-June; it is similar to moths of the genus Homosetia in being a small, narrow-winged tineid with tufts of raised scales on the forewing.

A second species of this genus, Stenoptinea sp. 2, also has been collected in central Illinois, as an adult at light in late May. Like S. auriferella, it resembles moths of the genus Homosetia.
