No image for this species.
Order: OPILIONESSuborder: EupnoiSuperfamily: PhalangioideaFamily: Phalangiidae                                                                                 
Comments: The sole representative of this genus in North America, where it was introduced from Europe (see Cokendolpher and Holmberg, 2018)
Species Comment: The type locality is Sweden but may have originated in the Caucasus and Asia Minor (Hillyard and Sankey, 1989)
Online Description/Photos: BugGuide Google, iNaturalist, Wikipedia, GBIFTechnical Description: Hillyard and Sankey (1989)
Comments: A moderately large harvestman. The ground color is gray to brown, with the central figure on the abdomen obscure or absent (Hillyard and Sankey, 1989). A pattern of dark bars spotted with pale tubercles is present over much of the dorsal surface.
Total Length: 5.0-7.0 mm, males; 6.0-9.0 mm, females (Hillyard and Sankey, 1989)Adult ID: identifiable by photo
Structural Features: Femora of the legs are angular and along with the patellae and tibiae are provided with rows of denticles and black-tipped spines; two rows of five to eight spines are located on the top of the ocular tubercle (Hillyard and Sankey, 1989)
Distribution in North Carolina
Comments: Why this species has been found only at the summit of Mt. Mitchell in North Carolina rather than the disturbed areas around cities where it routinely occurs elsewhere is unexplained.

Habitats and Life History
Habitats: Our one record for this species comes from the Spruce-Fir zone at the top of Mt. Mitchell. However, it is associated with a wide variety of disturbed habitats in Europe, including
Observation Methods: Hillyard and Sankey (1989) report that this species can be found on walls, fences, buildings, and tree trunks.
Abundance/Frequency: Not enough data are available to estimate either the frequency of occurrence or abundance of this species in North Carolina
Status in North Carolina
Natural Heritage Program Status:
Natural Heritage Program Ranks: [GNR] [SNA]
State Protection: Arachnids are not protected under state law, although permits are needed to collect them in State Parks and other public and private nature preserves. This species is introduced and is not in need of any conservation efforts. It seems unlikely to displace any of our native harvestmen, most of which live in mesic forests rather than open or disturbed habitats.
Comments: Exotic, originating in Asia Minor (Hillyard and Sankey, 1989). This species is found primarily in the northern states, at least in the East (in the West, it has been recorded in Texas and New Mexico -- Cokendolpher and Lee, 2003). Our sole record appears to be the farthest south it has been found in the Appalachians. We currently know of only a single state record for this species.
