FIGURE 1 in Natural history and distribution of the enigmatic southern Appalachian opilionid, Fumontana deprehendor Shear (Laniatores: Triaenonychidae), with an assessment of morphological variation

FIGURE 1. Distribution of sampled Fumontana deprehendor in the southern Appalachian mountains. A total of 24 localities were sampled, including both previously published localities (Shear 1977, 1978), labeled here as GREENBR and JOYCE. Dark circles represent sampled localities, with the size of circles proportional to the number of specimens collected. Open circles represent unsuccessful collecting attempts. Dark lines represent the four regions of "predicted endemism" (defined in the text) used as grouping variables in morphological analyses. These areas are regional highlands separated by major lowland riverine barriers. Stippled areas indicate elevations above 1000 meters.
