Type material.

HOLOTYPE: 1 ♂ (UMM559) from northeast of Albuquerque, Bernalillo County, New Mexico, United States, 35.1303 -106.5521 5, 1667 m a.s.l., 30.x.1963, coll. L. Oakley, AMNH.

Etymology.

The specific epithet is a patronym in honor of Annie Dodge Wauneka (1910-1997), influential member of the Navajo Nation who worked tirelessly to improve education and health of the Navajo. Among other awards, she was bestowed the United States Presidential Medal of Freedom in 1963 by President Lyndon B. Johnson.

Diagnosis.

Ummidia waunekaae can be differentiated from U. rosillos by the lack of a pale dorsal heart patch and brush on the retrolateral face of tarsus IV. Males can be differentiated from U. rosillos , U. modesta , U. timcotai , U. gabrieli , and U. rodeo by having an embolus with an even curve and from U. mercedesburnsae by having relatively more spines on the retrolateral face of tibia I. Males can also be differentiated from U. gertschi and U. modesta by lacking a distinct comb on the retrolateral face of tarsus IV. Males disperse in October.
