Type material.

HOLOTYPE: 1 ♂ (UMM003) from Chincoteague National Wildlife Refuge, White Hills Ridge, 1.3 km N toll booth. Accomack County, Virginia, United States, 37.9083 -75.3568 5, 2 m a.s.l., 26.vi-10.vii.1998, coll. SM Roble, VMNH. PARATYPE: 1 ♀ (AUMS16243) from Newport News, Mariner’s Museum Park, Newport News County, Virginia, United States, 37.0588 -76.4846 1, 18 m a.s.l., 9.vii.2015, coll. RL Godwin, BME.

Etymology.

The specific epithet is a noun taken in apposition and is in reference to the Native American name for the type locality.

Diagnosis.

Ummidia gingoteague can be differentiated from all other eastern United States species on the basis of its small size. Ummidia gingoteague can be differentiated from U. audouini by the presence of a comb on the retrolateral face of tarsus IV, which is more defined than the comb in U. neilgaimani . Males can further be distinguished from U. neilgaimani , U. rongodwini , and U. okefenokee by the presence of spines on the prolateral aspect of tibia I and from U. rongodwini by lacking a pale dorsal heart patch. Males disperse from May to July.
