Taxon sampling

This study is based on 172 specimens (including 5 outgroup specimens) from 85 (sub)species of Ariantinae from across Europe, representing about half of the known species and all the currently accepted genera (see Appendix). Specimens were collected in the period 1957-2012 and most material was fixed and conserved in 70% ethanol or isopropanol. Some (old) specimens were stored in “spiritus” (methylated spirits), whereas the more recently collected specimens were preserved in 97% ethanol.
