Diagnosis.

Ummidia nidulans is a relatively large species (CL 11-13.5), which can be differentiated from U. tibacuy , U. asperula , and U. neblina by the presence of a defined comb of long spinules on the retrolateral face of tarsus IV. Females can be further distinguished from all geographically proximate species by having a large number of distal endite cuspules (> 90 vs 30-54) and spermathecae which are straight with rounded, anteriorly facing bulbs.

Female neotype.
