Type material.

HOLOTYPE: 1 ♀ (BMEA101781) from Las Cuevas Field Station, 15 kilometers east of Caracol, Cayo, Belize, 16.733 -88.986 1, 650 m a.s.l., 29.vi-3.vii.2019, coll. JE Bond, BME.

Etymology.

The specific epithet is a patronym in honor of Dr. M. Francis Keller. Fran was the leader of the bioblitz in Belize, associated with UC Davis and the Bohart Insect Museum, when this specimen was collected.

Diagnosis.

Ummidia frankellerae females can be differentiated from all species by the presence of patches on either side of the spinnerets which are, in color and texture, similar to the book lungs and from all other geographically proximate species by the presence of a brush consisting of many spinules embedded in dense setae on the retrolateral face of tarsus IV. Females can be distinguished from all geographically proximate species except U. pustulosa by the sternum being relatively longer that wide (1.2 × long as wide vs subequal in other species) and from all except U. cuicatec by having spermathecae which curve laterally with a distal coil.
