Family Histeridae

            Tribe Histerini

 Hister dispar LeConte

Description and Taxonomy

Length 3.9-4.9 mm. The genus belongs to the tribe Histerini, which is characterized by the presence of expanded prosternal lobe, free labrum, antennal cavities situated under anterior angles of pronotum, dentate protibiae with straight protarsal furrow, antennal club with annuli not V-shaped, mesosternum without median projection and prosternal base without emargination (Kryzhanovskij & Reichardt 1976, Kovarik & Caterino 2000).  Five-six genera of Histerini are known in N America (Kovarik & Caterino 2000, Bousquet & Lapalante 2006), and three are present in GSMNP. Hister may be diagnosed by the at least slightly emarginate outline of the anterior margin of the mesosternum and lack of a complete innner subhumeral striae on elytra. This striae present in some species, but at most in the apical half of the elytra. Twenty-five described species in the genus occur in N. America, five of which are found in GSMNP. This species may be diagnosed by the combination of the following characters: protibia wide, tridentate, mandibles strongly elongate, subhumeral striae absent, sutural elytral striae long, almost complete.

Life History

The life history is virtually unknown, and the species was not treated in recent revisionary works on the genus (Caterino 1999a, b, 2002).  In GSMNP, the species was collected once, on pig feces bait at 535 m elevation.

Distribution

Widespread in eastern N. America, but the distribution is poorly known. It has not been reported from Canada (Bousquet & Lapalante 2006). An incomplete list of records includes Georgia, Illinois, Kansas, Mississippi, Louisiana, South Carolina and Tennessee (Mazur 1997, Tishechkin, unpublished)

Conservation Concerns

Not under threat.
