Type material.

HOLOTYPE: 1 ♂ (UMM016), from Virginia Western Community College, Roanoke County, Virginia, United States, 37.2462 -79.9744 4, 333 m a.s.l., 26.x.1995, coll. MW Donahue, VMNH. PARATYPE: 1 ♀ (UMM240) from Red Oak, Charlotte County, Virginia, United States, 36.7698 -78.6356 6, 140 m a.s.l., 2.v.1968, coll. WW Baker, AMNH.

Etymology.

The specific epithet is a patronym in honor of Neil Gaiman, author of a number of fantasy and horror books with spider-based characters. In one book, American Gods, the main character is tied to the World Tree located "one hour south of Blacksburg," not far from the type locality of this species.

Diagnosis.

Ummidia neilgaimani can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV, which is less defined than the comb in U. rongodwini and U. gingoteague . Males can further be distinguished from U. gingoteague and U. carabivora by lacking spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. Males disperse from September to November.
