Taxonomic history

The was established by Norwegian arachnologist Embrik Strand in 1901. Several were transferred from other genera, particularly Erigone (e.g., O. vaginatus, O. flavus, O. rectangulatus, O. rotundus). Species described by Russian arachnologist Yuri M. Eskov in 1984 and 1991 account for nearly half the genus diversity.
