Clinidium apertum allegheniense
R.T. & J.R.Bell, 1975
Clinidium apertum allegheniense is a of wrinkled bark beetle described in 1975 by R.T. and J.R. Bell. It belongs to the Rhysodinae, a group of beetles highly specialized for life under bark and in decaying wood. The subspecies is part of the Arctoclinidium subgenus, which contains North American . Like other rhysodines, it exhibits morphological adaptations for navigating tight spaces in wood-decaying .

Identification
As a of Clinidium apertum, allegheniense would be distinguished from the nominate subspecies C. a. apertum by subtle morphological differences, likely in body proportions, surface sculpturing, or genitalic structures. Definitive identification requires examination of and comparison with the original description. Members of the Arctoclinidium subgenus generally show reduced and elongated, cylindrical bodies adapted for moving through wood galleries.
Habitat
Inhabits decaying wood and under bark, consistent with the of Rhysodinae beetles. The epithet "allegheniense" suggests association with the Appalachian Mountain region.
Distribution
United States; specifically the Appalachian region based on the epithet. Distribution records indicate presence in North America with confirmed occurrence in the USA.
Ecological Role
Contributes to wood decomposition processes as part of the of organisms inhabiting decaying wood. The precise ecological function within this has not been documented.

Taxonomic Note
placement varies between sources: Catalogue of Life places Rhysodinae within Carabidae, while iNaturalist recognizes Rhysodidae as a separate family. This reflects ongoing taxonomic debate regarding the rank of rhysodine beetles.
Data Deficiency
No observations recorded in iNaturalist and minimal distributional data available. The original description by Bell and Bell (1975) remains the primary source of information for this .
