Family Histeridae

            Tribe Histerini

 Hister coenosus Erichson

Description and Taxonomy

Length 4.7-6.4 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 presence of inner subhumeral striae on the elytra and non-dentate protibiae.

Life History

This is the most common cow dung-dwelling histerid in southern parts of N. America (Caterino 1999, Summerlin et al. 1981, 1993). The species also inhabits other types of mammal dung and occasionally has been found on carrion and decomposing vegetative materials. In GSMNP, it was collected in horse dung at several localities at 530-630 m elevation.

Distribution

Widespread in southern N. America and Central America, ranging from central California, southern Montana and Virginia to central Panama and the Greater Antilles (Caterino1999).

Conservation Concerns

Not under threat.
