Abstract
Lepidopsocids are well diversified in recent fauna, but fossil records remain very scarce. Echmepteryx (Loxopholia) dominicanus sp. nov. from Dominican amber is herein described and illustrated. This species is attributed to subfamily Lepidopsocinae Enderlein, 1903 and assigned to genus Echmepteryx Aaron, 1886. This new record is the second oldest lepidopsocid. It is also the first species in this family to be described from Dominican amber and the only fossil record of Lepidopsocinae.
