Type material.

HOLOTYPE ♂ (UMM158) from Tekom, Yucatán, Mexico, 20.0603 -88.2654 1, 96 m a.s.l., 17.iv.1940, coll. T. Sanderson, AMNH. PARATYPE: 1 ♀ (UMM576) from Chichén Itzá, Yucatán, Mexico, 20.6826 -88.5686 5, 38 m a.s.l., 16.vii.1952, coll. J Ballister, D Ballister AMNH.

Etymology.

The specific epithet is in honor of Brandi Carlile, an American singer-songwriter who, along with Tim and Phil Hanseroth, established the Looking Out Foundation, which raises money and awareness for numerous causes to include supporting child victims of war, world hunger, LGBT rights, and the empowerment of women. Carlile founded the annual Girls Just Wanna Weekend Festival to counter the lack of female representation at mainstream music festivals, which takes place near the type locality for this species.

Diagnosis.

U. brandicarlileae can be distinguished from all other geographically proximal species except U. yojoa by lacking either a defined brush or comb on the retrolateral face of tarsus IV. Males can be differentiated from U. cuicatec and U. zilchi by having a sinuous embolus without a strong bend, from U. huascazaloya , U. anaya , U. zilchi , U. riverai , and U. hondurena by having fewer spines on prolateral (2 vs 7-28) face of tibia I and from U. riverai by lacking a pale dorsal heart patch on the abdomen. Males can be further differentiated from all other geographically proximate species by having tarsi I relatively short and thickened proximally. Females can be differentiated from U. cuicatec , U. frankellerae and U. matagalpa by having spermathecae that bend medially then anteriorly. Males disperse from April to July.
