We've decided that it's no longer necessary to keep the cylindricus group as all of the species that were not part of it have been moved to other genera. Even originally created it back when Ocyptamus was polyphyletic as a way to accommodate the species of Ocyptamus sensu stricto, but now Ocyptamus, as defined on iNaturalist, is equivalent. When Even split Ocyptamus on BugGuide he neglected to merge the cylindricus group back into the genus. (BugGuide has been fully updated.)
