Fig. 63 , Map 5 Type material. HOLOTYPE: 1 ♀ (UMM452) from the eastern slopes of the Cerro Hoya, Los Santos, Panama, 7.2986 -80.0014 6, 940 m a.s.l., 6.iv.1966, coll. CW Myers, AMNH Etymology. The specific epithet is a noun taken in apposition and refers to the type locality, the eastern slopes of the Cerro Hoya. Diagnosis. Ummidia cerrohoya can be differentiated from all geographically proximate species by having very few (4 vs 20 or more) proximal endite cuspules. Females can be further distinguished from U. hondurena , U. yojoa , U. rugosa , U. varablanca , U. quepoa , and U. erema by having a distinct comb of long spinules on the retrolateral face of tarsus IV and from all geographically proximate species except U. carlosviquezi by having straight, simple spermathecae.
