Taxonomy 2.0: Sequencing of old type specimens supports the description of two new species of the Lasiocampa decolorata group from Morocco (Lepidoptera, Lasiocampidae).

The type of Lasiocampa decolorata (KLUG, 1830), collected in 1820, was successfully barcoded to generate a 658bp COI-fragment after 194 years. The resulting molecular data allowed the description of two closely related species from Morocco: Lasiocampa hannae SPEIDEL, MOOSER & WITT sp. n. from the Anti Atlas and Lasiocampa editae SPEIDEL, MOOSER & WITT sp. n. from the High Atlas.
