Type material.

HOLOTYPE: 1 ♂ (UMM757) from Lucía Lutz farm, Quepos, Puntarenas, Costa Rica, 9.4828 -84.0948 1, 102 m a.s.l., 26-28.v.2010, coll. A Solis BME.

Etymology.

The specific epithet is a noun taken in apposition and refers to the Quepoa, who inhabited the region of the type locality during the colonial era.

Diagnosis.

Ummidia quepoa are relatively large spiders (CL 8-13). Males can be distinguished from U. hondurena , U. yojoa , U. rugosa , and U. erema by having a relatively short embolus with a single even curve and from U. yojoa and U. varablanca by the presence of many prolateral (23 vs 0) and retrolateral (44 vs 2-3) spines on tibia I. Males can be further differentiated from U. rugosa and U. riverai by the lack of a pale dorsal heart patch on the abdomen, though occasionally with a faint opalescence. Females can be differentiated from all geographically proximate species by having spermathecae which curve laterally and then bend posteriorly and then anteriorly at the distal end.
