Type material.

HOLOTYPE: 1 ♀ (UMM230) from Monserrate above Bogotá, Cundinamarca, Colombia, 4.6049 -74.0565 5, 3152 m a.s.l., 27.iv.1965, coll. PR Craig, DL Craig, AMNH.

Etymology.

The specific epithet is a noun taken in apposition. It is the Muisca name for Monserrate, Quijichacaca, which translates to “grandmother’s foot".

Diagnosis.

Ummidia quijichacaca can be differentiated from all geographically proximate species by having the carapace angular and longer than wide and legs which are darker distally. Females 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 spermathecae which are straight with wide, flat, anteriorly facing bulbs.
