Taxonomic Note
The placement of Calymmaderus has been subject to revision. GBIF lists the family as Anobiidae, while iNaturalist and Wikipedia list it as Ptinidae. This reflects ongoing taxonomic debate regarding the circumscription of Ptinidae versus Anobiidae. The Calymmaderus is currently treated as part of Ptinidae in most modern classifications.
Data Limitations
Despite being described in 1905, C. obsoletus remains poorly known. iNaturalist shows only 5 observations, and no detailed ecological or behavioral studies appear to have been published. The epithet 'obsoletus' (meaning worn, decayed, or obsolete) may refer to coloration or pattern, but the original description has not been consulted.
