Type material.

HOLOTYPE ♂ (UMM161) from Globe, Gila County, Arizona, United States, 33.3940 -110.7864 6, 1072 m a.s.l., 17.vii.1967, coll. MA Cazier, AMNH. PARATYPE: 1 ♀ (UMM666) from San Tan Valley, Pinal County, Arizona, United States, 33.1788 -111.4942 1, 474 m a.s.l., 8.ii.2016, coll. TA Cota, BME.

Etymology.

The specific epithet is a patronym named for Timothy Cota who has collected many specimens used in this revision to include the female paratype of this species and has studied the group’s natural history for many years.

Diagnosis.

Ummidia timcotai can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and from all geographically proximal species except U. rosillos by the presences of a brush on the retrolateral face of tarsus IV. Males can be differentiated from U. mercedesburnsae , U. paulacushingae , U. waunekaae , and U. gertschi by having a sinuous embolus and from all geographically proximal species by tibia I being very spinose. Females can be differentiated from U. gertschi , U. modesta , and U. mercedesburnsae by having spermathecae that curve laterally. Males disperse from July to August.
