Actiastes spp. (female) ( Fig. 41 )

Comments. Female Actiastes Casey cannot be identified to species. These specimens probably represent Actiastes fundatum Grigarick and Schuster and/or Actiastes suteri (Park) , both of which are known from GSMNP. Range: Alabama, Georgia, North Carolina, Tennessee. Habitat: rhododendron duff, tree holes, leaf litter. Collection Method: sifting/Berlese litter. Biology: unknown, members of this subfamily are predatory. Present Study: significantly higher abundance in leaf litter and primary forest, indifferent to season. References: Grigarick and Schuster 1971; Chandler 1990b.

Adranes lecontei Brendel ( Fig. 42 )

Range: Kentucky, Mississippi, New York, Pennsylvania, Tennessee. Habitat: lives in nests of Lasius spp. ants ( Hymenoptera : Formicidae ); nests have been found in beech logs in advanced stages of decay.

Collection Method: sifting Lasius spp. ant nests, rarely sifting/Berlese forest litter. Biology: obligate myrmecophile on Lasius spp. ants; adults feed on fluids obtained from their adult and immature hosts; possibly feed on dead immature ants; see Park (1932a) and Akre and Hill (1973) for interesting behav- ioral observations of the genus. Present Study: significantly higher abundance in secondary forest, indifferent to substrate or season, probably heavily influenced by their host.

Batrisodes beyeri Schaeffer ( Fig. 43 )

Range: North Carolina. Habitat: forest leaf litter. Collection Method: sifting/Berlese litter. Biology: unknown; some members of this genus are associated with ants, others are litter dwellers, members of this subfamily are predatory, see Park (1932b) about feeding behavior of Batrisodes lineaticollis Aubé (as B. globosus LeConte ). Present Study: significantly higher abundance in leaf litter and primary forest, indifferent to season. References: Schaeffer 1906; Park 1932b (as B. globosus LeConte ), 1947, 1948.
