 Diagnosis. Anterior pair of spinnerets essentially round in A. gertschi; all spinnerets clearly longer than wide in other species of Atypoides.   
 Distribution. Cascade and eastern Siskiyou Mountains in southern Oregon south and east into the northern Sierra Nevada Mountains of California (Figs. 1, 3; Coyle 1968: map 1).   
 Wandering Activity. Male wandering activity was concentrated between late July and early September while females were active June­early July (Fig. 6). Immatures were collected throughout the trapping period in 1998 but only in late June in 1999.   
 Comments. Atypoides gertschi was found in the eastern Siskiyou and southern Cascades Mountains study areas. Within the eastern Siskiyou Mountains it was the third most abundant spider collected, comprising 8.1% of the total, and was collected in 12 of 18 sites. Although it was found in both burned and unburned sites (5 burned and 7 unburned sites), 72.1% of adults collected were from unburned sites. Atypoides gertschi was found in 8 of 16 sites in the southern Cascade Mountains (3 thinned and 5 unthinned sites), but was considerably less common, comprising only 0.6% of the total number of spiders collected. Overall, only 5 of 290 individuals collected were female. Known biological information for this species has been summarized by Coyle (1971).
