Source discrepancy exists regarding count: Wikipedia states 'over forty described species' while iNaturalist reports 'one described species in Aglyptinus, A. laevis'. This likely reflects incomplete database synchronization rather than actual taxonomic revision. The Catalogue of Life and GBIF accept the without enumerating species.

Research gaps

Published biological studies are sparse. A dedicated study on Aglyptinus laevis (LeConte) exists but full text content was unavailable for extraction. Most -level remains undocumented in accessible literature.
