Identification
Distinguished from other flat bark beetles by combination of: (1) specific pattern of yellowish markings referenced in the epithet 'flavosignatus'; (2) genitalic characters (male structure is the primary diagnostic feature for in this ); (3) geographic occurrence in North America. Separation from congeneric species requires examination of male genitalia and detailed comparison of elytral punctation and color pattern.
Habitat
Associated with dead or dying wood and beneath bark of trees, the typical for Laemophloeidae. Specific tree associations for this have not been documented.
Distribution
Recorded from North America. Precise range boundaries within this region are not established in available literature.
Ecological Role
Member of the saproxylic ; contributes to decomposition of dead wood and nutrient cycling in forest . Specific ecological functions for this are not documented.
Human Relevance
No documented economic importance. Not known as a pest of living trees or stored products.

Taxonomic Note
The Charaphloeus was established for formerly included in broader concepts of Laemophloeus. The Laemophloeidae has undergone significant taxonomic revision, and species-level in Charaphloeus relies heavily on male genitalic characters not visible in routine field observation.
