Taxonomic Note
placement has shifted historically between Anobiidae and Ptinidae; current sources (iNaturalist, recent treatments) recognize Ptinidae as the valid family. The is extremely poorly known, with only one iNaturalist observation as of source date.
Data Deficiency
This exemplifies significant gaps in basic natural history knowledge for many North American beetles, despite being described nearly 50 years ago.
