Only the female of N. frenata is known. The carapace is mediumbrown, paler in the ocular area to the fovea, with dark edges and slight radial infuscation from the fovea, especially to the base of the ocular area. The abdomen is brownish black. The legs are yellowish brown with reddish distal segments. Total length is 6.8 mm.
Conservation
Nomisia frenata is listed as Data Deficient for taxonomic reasons. The species has a very small range and too little is known about the location, distribution and threats for an assessment to be made. More sampling is needed to collectmales and determine the species' actual range.
Taxonomy
The species was originally described by Purcell in 1908 as Callilepis frenata from Kamaggas. It was later transferred to the genusNomisia by Dalmas in 1921. It has not been revised since and only the female is known.
