Comparative discussion
Thus far, this species has been reported in the scientific literature only from its type locality, Yaquina Head, Oregon, USA. However, in an unpublished student report Poljakova (1991) mentioned the species from Paramushir Island (Kuril Islands) and from the Komandorskiye Islands. Unfortunately, the report does not substantiate this finding and identification with drawings or photographs of the specimens from Kamchatka; the report merely reproduces figures of the external appearance and copulatory apparatus already published by Holmquist and Karling (1972). Furthermore, the material studied by Poljakova (1991) could not be retrieved for re-examination. Although this record of O. opisthopora from Kamchatka may well be correct, and very interesting from a biogeographical point of view, we feel that it requires more supporting evidence.
