DistributionUSA (SE California: Mojave Desert, Death Valley; Arizona: Yuma County)

Type locality: "Fort Buchanan, Arizona" (in errore, probably from San Bernardino County, California fide HEIFETZ 1941).  
TypesHolotype: USNM 6063 
DiagnosisDiagnosis: Ventrolateral blotch present. Two, or occasionally one, black gular crescents present, widest at the middle of the throat; anterior to these one or two V-shaped markings are usually present. The crescents occasionally reduced to short black bars with indistinct ends curving anteriorly. Five rows of internasal scales normally present. Femoral pores 22 to 47, averaging considerably higher than in U. n. notata. Fringe spines on fourth toe 28 to 40, also averaging higher than in U. n. notata. Dorsal ocelli scattered, and never forming a semilineate pattern (see fig. 1, A). Black never fusing into lines on neck. Preanal spots often present, especially in Daggett specimens. Two enlarged black spots usually present on the sides anterior to the insertion of the femur; these are especially distinct in Blythe Junction and Ford Dry Lake specimens (from HEIFETZ 1941).

DIAGNOSIS: species most closely related to the notata group. A dorsal pattern of ocelli, not forming broken longitudinal lines over the shoulder. Ventrolateral blotch present. Internasal scales usually five. Breeding coloration ephemeral, consisting of a yellow-green ventral wash, becoming pink along the lateral abdominal fold (Norris 1958).

Description: Norris 1958: 284 
CommentApparently, Cope used two names for the same species in his description. U. scopifera is named first but only U. scoparia has a description.

Distribution: see map in Gottscho et al. 2016: Fig. 1, Derycke et al. 2020: 68 (Fig. 1).
