Type material.

HOLOTYPE: 1 ♀ (UMM118) from Matagalpa, Matagalpa, Nicaragua, 12.9207 -85.9172 6, 720 m a.s.l., coll. WB Richardson, AMNH.

Etymology.

The specific epithet is a noun taken in apposition and is in reference to the type locality, Matagalpa.

Diagnosis.

Ummidia matagalpa females can be differentiated from all other geographically proximate species by having spermathecae with only a slight medial curve and from all except U. zilchi , U. carlosviquezi , and U. cerrohoya by the presence of a defined comb on the retrolateral face of tarsus IV.
