H. abdominalis is synonymized with H. thestealis after the abdominalis type specimen was reidentified as thestealis. But specimens previously thought to be abdominalis are a mix of H. thestealis, H. pertextalis, H. aquilonalis n. sp., and H. fraxinalis n. sp. It would be unhelpful to relabel all abdominalis records to thestealis in a simple synonymization. This taxon change is thus a split without atlases, intended to move current abdominalis records to the genus rank. Each record should be individually reidentified given the new diagnostics in the revision.
