Eutyphlus spp. (female) ( Fig. 49 )

Comments. Eutyphlus females cannot be reliably identified. These female specimens are probably representative of the four species that have been collected in GSMNP. The vast majority are probably Eutyphlus similis LeConte. Range : eastern North America, particulary southern Appalachians. Habitat: leaf litter, rhododendron litter. Collection Method: sifting/Berlese litter. Biology: unknown, members of this subfamily are predacious. Present Study: significantly higher abundance in leaf litter and primary forest, indifferent to season. References: Park 1956; Chandler 1990b; Downie and Arnett 1996; Newton et al. 2001.
