Aphelosternus interstitialis
(LeConte, 1851)
Aphelosternus interstitialis is a of clown beetle in the Histeridae, first described by John L. LeConte in 1851. The species is native to western North America, with confirmed records from California. Like other members of the Saprininae, it is likely associated with decomposing organic matter and carrion, though specific ecological details remain poorly documented. The Aphelosternus is a small group within the diverse Histeridae, and species-level for most members is not well studied.

Identification
Members of Aphelosternus can be distinguished from related saprinine by their distinctive antennal club structure and elytral punctation patterns. A. interstitialis specifically may be recognized by the fine, punctures between the primary elytral , as suggested by its epithet. Accurate identification typically requires examination of male genitalia and comparison with type material.
Distribution
Known from California, USA. GBIF records indicate presence in North America with specific locality data for California.
