Coleoptera of Great Smoky Mountains National Park Species Pages

Family Eucnemidae

            Tribe Melasini

 Rhagomicrus bonvouloiri (Horn)

Description and Taxonomy

Length 2.5-4.8mm. In addition to tribal characters (prominent lateral pronotal ridges, notosternal antennal grooves, deep pits near procoxae) the genus may be diagnosed by simple elytral apices, parallel-sided metacoxal plates and short cylindrical body shape.  Four species are reported for Nearctic Region, three of them are known in the East (Muona 2000) and only one is found in GSMNP.

Life History

Specimens from the GSMNP were collected with Malaise traps and by unspecified hand collecting. They were found from mid to late June at 480-625 m elevation.  Although it is a common North American species, the only one host genus is known, i.e. Carya ( Muona 2000).

Distribution

Widespread in eastern North American, known from Missouri and Ontario to Louisiana and Florida. Records from the second half of the XX century are uncommon (Muona 2000).

Conservation Concerns

Not under threat.
