Aleodorus bilobatus (Say) ( Fig. 29 )

Range: eastern North America: Ontario to southern New England, south to Georgia, west to Illinois and Iowa. Habitat: moist habitats, under bark, sifted vegetable debris, dead grass, moss, and duff. Collection Method: sifting/Berlese leaf litter, hand collection. Biology: unknown, specimens have been collected from March to November. Present Study: significantly higher abundance in leaf litter, primary forest, and fall. References: Hoebeke 1985; Downie and Arnett 1996; Gouix and Klimaszewski 2007. Athetini gen. spp. Casey ( Fig. 30 )

Comments. These specimens could only be reliably identified to Athetini , a large difficult tribe. Seev- ers (1978) characterization of the tribe and genera is inadequate. Currently 64 genera are recognized within the tribe in North America ( Newton et al. 2001) but a complete revision is needed. Gusarov (2002a –e, 2003a–e, 2004a–b) has greatly contributed to our knowledge of many genera and Elven et al. (2010) provided the first molecular phylogeny of the tribe, but more work needs to be done. Range: throughout North America. Habitat: ubiquitous; decaying plants and animals, dung, bird and mammal nests, riparian areas, ant nests, under bark and logs. Collection Method: sifting/Berlese leaf litter. Biology: unknown; predators. Present Study: significantly higher abundance in leaf litter and spring, indifferent to forest type.

Leptusa gimmeli Park and Carlton ( Fig. 31 )

Range: Tennessee. Habitat: known only from Albright Grove, GSMNP, old growth forest. Collection Method: sifting/Berlese leaf litter, one specimen collected from dead wood with emergence chamber.

Biology: unknown. Present Study: significantly higher abundance in leaf litter, primary forest, and fall. References: Park et al. 2010.
