Ent. Tidskr. 132 (2011) DNA barcoding in species complexes of Stigmella DNA barcoding resolves species complexes in Stigmella salicis and S. aurella species groups and shows additional cryptic speciation in S. salicis (Lepidoptera: Nepticulidae) ERIK J. VAN NIEUKERKEN, MARKO MUTANEN & CAMIEL DOORENWEERD Nieukerken, E.J. van, Mutanen, M. & Doorenweerd, C.: DNA barcoding resolves species complexes in Stigmella salicis and S. aurella species groups and shows additional cryptic speciation in S. salicis (Lepidoptera: Nepticulidae). [DNA analyser visar artuppdeln- ingen inom Stigmella salicis- och S. aurella grupperna och att det finns ytterligare kryptiska arter inom S. salicis (Lepidoptera: Nepticulidae).] – Entomologisk Tidskrift 132 (4): 235-255. Uppsala, Sweden 2012. ISSN 0013-886x. We sequenced the mitochondrial barcoding marker COI and nuclear marker EF1-alpha for most Nordic and other European species of the Stigmella salicis and S. aurella species groups. In the S. salicis group both markers confirm the synonymy ofS. lappovimella with S. zelleriella. Specimens previously identified as Stigmella salicis and S. vimineticola are shown to form a complex of several cryptic species for which the taxonomy needs to be worked out. The species previously recorded as S. vimineticola from Norway represents probably an unnamed species. In the S. aurella group, the oligophagous Rosaceae feed- ers S. aurella and S. poterii are confirmed to be each a single oligophagous species. The synonymy between Stigmella ulmariae from Filipendula ulmaria and S. filipendulae from Filipendula vulgaris is corroborated. E.J. van Nieukerken & C.
