Figs 57 , 58 , Map 5 Type material. HOLOTYPE: 1 ♂ (UMM239) from 6 kilometers south of San Vito, Puntarenas, Costa Rica, 8.7125 -83.0051 1, 355 m a.s.l., 13-18.iii.1967, coll. C Valerio, AMNH. PARATYPE: 1 ♀ (UMM747) from Las Cruces, Puntarenas, Costa Rica, 8.7919 -82.9551 1, 1227 m a.s.l. coll. C Viquez, P Jordan 7-8.xi.2001, BME. Etymology. The specific epithet is a patronym in honor of Carlos Viquez, a Costa Rican arachnologist who assisted the authors in the field and provided a great deal of the Costa Rican material used in this revision, to include one of the type specimens for this species. Figure 57. Ummidia carlosviquezi sp. nov. from Puntarenas, Costa Rica. A male habitus illustration UMM239 B female habitus illustration UMM747. Scale bars: 4.0 mm. Diagnosis. Ummidia carlosviquezi 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 (22 vs 0) and retrolateral (35 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 and from U. matagalpa and U. quepoa by the presence of a comb on the retrolateral face of tarsus IV. Females can be distinguished from all geographically proximate species except U. cerrohoya by having straight, simple spermathecae. Description of male holotype. Specimen preparation and condition .
