Pachylomerus rugosus Karsch, 1880: 388; female holotype (ZMB3244) from Costa Rica, 9.7703 -83.7751 9, 1388 m a.s.l., coll Hoffman, deposited in ZMB, examined.

Hebestatis lanthanus Valerio, 1988: 228; male holotype and female allotype from Universidad de Costa Rica, main campus, San Jose Province, Costa Rica, 9.95 -84.0667 1, 1207m, coll R Aymerich iv.1981, deposited Museo de Zoología, University of Costa Rica, syn. nov. We were unable to examine the holotype specimen, but are certain, after examinations of Valerio’s (1988) description and illustrations, and examination of paratype (UMM544) deposited AMNH that these specimens were misidentified as belonging to the genus Hebestatis and that the holotype is actually a male specimen of U. rugosa based on the embolus and presence of a pale dorsal heart patch.

Diagnosis.

Ummidia rugosa males can be differentiated from all geographically proximate species except U. riverai by the presence of a pale dorsal heart patch and all but U. riverai and U. hondurena by the presence of a comb of alternating long and short heavy hairs on the retrolateral face of tarsus IV. Males can be 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. yojoa and U. varablanca by the presence of many prolateral (28 vs 0) and retrolateral (42 vs 2-3) spines on tibia I. Females can be distinguished from all geographically proximate species except U. hondurena and U. erema by having spermathecae which bend first medially and then anteriorly.

Remarks.

The abdomen of the female holotype specimen of Ummidia rugosa is missing. For this reason, we have also included a description of a female exemplar.
