(Casey, 1884)

lined flat bark beetle

Rhabdophloeus horni is a of lined flat bark beetle in the Laemophloeidae, first described by Casey in 1884. The species is found in North America. Members of this family are characterized by their flattened body form, an for living beneath bark. Very little specific biological information has been published for this particular species.

Identification

Members of Laemophloeidae can be distinguished from other flat bark beetle by their antennal structure and body form. Rhabdophloeus may be separated from related by subtle characters of the pronotum and , though specific diagnostic features for R. horni require examination of original description or keys. The species name 'horni' likely honors American coleopterist George Henry Horn (1840–1897).

Appearance

As a member of Laemophloeidae, this has a distinctly flattened body adapted for living in tight spaces beneath bark. The is characterized by elongate, parallel-sided bodies with that often have distinct longitudinal lines or . Specific morphological details for R. horni are not well documented in accessible literature.

Habitat

Found beneath bark of dead or dying trees, typical for Laemophloeidae. Specific tree associations for this are not documented.

Distribution

North America. GBIF records indicate presence in the region, with iNaturalist documenting limited observations.

Ecological Role

As with other Laemophloeidae, likely contributes to decomposition of dead wood and nutrient cycling in forest . Specific ecological functions for this have not been studied.

More Details

Taxonomic note

The Laemophloeidae was historically treated as a of Cucujidae but is now recognized as a distinct family within Cucujoidea. The Rhabdophloeus is one of approximately 40 genera in the family.

Data deficiency

This is poorly represented in biological databases and literature. The 5 iNaturalist observations suggest it is rarely encountered or underreported, though this may reflect limited identification capacity rather than true rarity.
