Type material.

HOLOTYPE ♂ (CNAN-T01385) from Municipio de Santiago de Anaya Hidalgo, Grutas Xoxafi, Hidalgo, Mexico, 20.3884 -99.0275 1, 2020 m a.s.l., coll. 7-8.vi.2019, PE Cushing, E García, E González Santillán, DL Batista Perales, J Rojas Castillo, CNAN.

Etymology.

The specific epithet is a noun taken in apposition and is in reference to the type locality, the town of Santiago de Anaya.

Diagnosis.

Ummidia anaya can be differentiated from U. huascazaloya by lacking a defined comb on the retrolateral face of tarsus IV and by having a palpal tibia (1.85 × long as wide vs 3.25 ×) and tarsus IV (2.9 × long as wide vs 3.6 ×) which are less elongate as well as having more, smaller endite cuspules (22 vs 10). Males can be differentiated from U. cuicatec and U. zilchi by having a sinuous embolus without a strong bend and from U. cuicatec , U. zebrina , U. brandicarlileae , and U. yojoa by having relatively more spines on the prolateral face of tibia I (11 vs 0-2). Males can be differentiated from U. riverai by lacking a pale dorsal heart patch on the abdomen. Males disperse in June.
