Scytonotus virginicus (Loomis) 
Diagnosis — Tibiae of legs 13-20/22 of males without distal lobes; 
tibiotarsus and endomerite subequal in length; medial lamina with 
two distinct teeth, segregated to varying distances; distal lamina with 
two or three teeth, an apical tooth followed by one or two moder- 
ately segregated teeth; lateral lamina varying in length but with a 
strong proximal spine; females with paranota of segments 5-9 not 
reduced. 
Remarks — Hoffman (1962b) distinguished S. virginicus and 
michauxi by the degree of segregation of the teeth on the medial 
lamina (narrow in the former, wide in the latter) and by the pres- 
ence of two ( virginicus ) or three ( michauxi ) teeth on the distal 
lamina. Although Chamberlin and Hoffman (1958) reported that S. 
virginicus ranged southward through the Blue Ridge Province to 
Linville Falls, Burke County, North Carolina, Hoffman (1962b) stated 
that the species was unknown on the Blue Ridge south of the 
Roanoke River and assigned the name michauxi to forms in North 
Carolina. Material secured in the past 30 years shows that these 
two forms intergrade in southwestern Virginia from Mt. Rogers, Gray- 
son County, to Pinnacles of Dan, Patrick County, and hence that 
they are only subspecifically related. As S. virginicus is the older 
name, michauxi is reduced to subspecific status.
