Fig. 53 , Map 5 Type material. HOLOTYPE: 1 ♂ (UMM186) from Agua Azul, Lake Yojoa, Dept. of Cortes , Honduras, 14.8715 -87.9821 6, 639 m a.s.l., 30.v.1964, coll. RE Woodruff, AMNH. Etymology. The specific epithet is a noun taken in apposition and is in reference to the type locality, Lake Yojoa. Diagnosis. Ummidia yojoa males are relatively stocky spiders and can be differentiated from all geographically proximate species by the presences of a soft brush on the retrolateral face of tarsus IV and from all except U. zebrina and U. varablanca by lacking prolateral spines and having very few retrolateral spines (3 vs 10-44) on tibia I. Males can be further distinguished from U. zilchi , U. carlosviquezi , U. varablanca , and U. quepoa by possessing a sinuous embolus, rather than one with an even single curve and from U. riverai and U. rugosa by lacking a pale dorsal heart patch.
