Identification
Distinguished from similar Idia by its black coloration. Formerly, Idia occidentalis was considered a but is now recognized as a separate species. The two recognized subspecies of I. lubricalis (partitalis and cobeta) may show geographic variation in appearance. Identification to species level requires examination of specimens; dissection may be necessary for definitive identification from closely related species.
