Synonyms and other taxonomic changes
Carroll (2010)(1) lists both J. antica (Walker) and J. sanguinolenta (Fabricius) from southern Florida and southward, however true sanguinolenta occurs in Puerto Rico and the Virgin Islands, but not in the continental US (Henry & Froeschner 1988, Mead & Fasulo 2007, Gollner-Scheiding 1979)
Carroll (2010)(1) uses Jadera bayardae Gollner-Scheiding 1982, but Henry & Froeschner (1988)(2) considers this taxon to be an unnecessary new name for J. hinnulea Gollner-Scheiding 1979
