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.
