Sonoma spp. (female) ( Fig. 68 )

Comments. Female Sonoma Casey cannot be reliably identified. These female specimens are prob- ably representative of the eight described species that have been collected in GSMNP. Range: central eastern and western United States. Habitat: leaf litter, rhododendron litter, rotten wood. Collection Method: sifting litter and rotten wood (with Berlese funnel), Lindgren funnel, Malaise trap, flight intercept trap, rarely at UV light, emergence chamber. Biology: unknown, members of this subfamily are predacious. Ferro et al. (2012a): significantly higher abundance in CWD5, indifferent to forest type and season. Present Study: significantly higher abundance in CWD3–4. References: Chandler 1990a; Downie and Arnett 1996; Newton et al. 2001; Ferro and Carlton 2010.

Trimioplectus obsoletus Brendel ( Fig. 69 )

Range: Pennsylvania south to North Carolina, west to Illinois. Habitat: rotting wood and tree holes.

Collection Method: sifting/Berlese, emergence. Biology: unknown, members of this subfamily are predacious. Present Study: not significantly associated with any substrate or forest type.
