Technical Description:
Shear (1975a)
Comments:
A moderately small but long-legged harvestmen. Easily recognized by the very large eyes that take up most of the surface of the cephalothorax. The dorsal surface of the body is dark purplish brown, with a distinctive white dorsal stripe that runs from the top of ocular tubercle onto the abdomen; the sides are silvery-white and pale intersegmental bands are also present on the dorsum of the abdomen (Shear, 1975a; Schultz, 2018). The huge eyes distinguish species from all of our other harvestmen except Acropsopilio boopis. That species is much smaller, however, and lacks the distinctive white dorsal stripe.
Total Length:
3 mm (Shear, 1975a)
Adult ID:
identifiable by photo
Structural Features:
This species is probably parthenogenic with only a very males having ever been observed (Shear, 1975a).
Distribution in North Carolina
Comments:
All of our records come from the Black Mountains, including the lower slopes of Mt. Mitchell. This species is primarily northern, occurring from New England and southern Canada west to the Ohio Valley (Shear, 1975a). The Cowee Mountains in North Carolina appear to represent the southernmost extent of its range.
