Coleoptera of Great Smoky Mountains National Park Species Pages

Family Eucnemidae

            Tribe Macraulacini

 Dromaeolus turnbowi Muona

Description and Taxonomy

Length 5-8mm. The genus is an artificial collection of species that is difficult to characterize (Muona 2000). However, many eastern species, including those found in GSMNP may be diagnosed by the following combination of characters: deep narrow lateral antennal grooves, epipleura without groove, simple claws and elongate pronotum.  In the Nearctic Region, the genus is represented by nine species subdivided into four informal species groups.  Six species are distributed the east (Muona 2000), three in GSMNP. This species may be separated from the other GSMNP species by the relatively short pronotum and bicolored, black and white, body surface setae.

Life History

This is one of rarer eucnemid species in GSMNP. A few specimens were collected by Malaise traps at Cades Cove and Twin Creeks ATBI plots from early June to late July at 540 and 625 m elevation.  The life history of the species is completely unknown (Muona 2000).

Distribution

Distribution of this species is poorly known since it was described from a few specimens in 2000 and only a few have been found since. Apparently, distributed in south-eastern  North America, known previously from Georgia, Louisiana, Mississippi and West Virginia (Muona 2000).

Conservation Concerns

Apparently not under threat, though the incomplete state of knowledge of its life history makes a conservation assessment problematic.
