Dyseriocrania is a of small primitive in the Eriocraniidae, first described by Spuler in 1910. The genus contains four recognized distributed across the Holarctic region. Members are characterized by their diminutive size, with wingspans ranging from 9 to 13 mm, and relatively broad wing compared to body proportions. These moths represent one of the more derived genera within the Eriocraniidae, a family considered among the most basal lineages of Lepidoptera.

Identification
Distinguished from the related Eriocrania by subtle genitalic differences and wing venation patterns; accurate identification to level typically requires dissection and examination of genitalia. The broad wing shape relative to small body size separates Dyseriocrania from most other microlepidopteran . Within Eriocraniidae, Dyseriocrania species generally show more pronounced metallic coloration than Eriocrania species.
