DistributionUSA (SE California, SW Arizona),
Mexico (NE Baja California Norte)

Type locality: Mojave Desert (in error). Restricted to the “Colorado Desert” by HEIFETZ 1941 and to “the vicinity of Yuma, Arizona” by SMITH & TAYLOR 1950.

Lectotype locality: Yuma Desert, Yuma County, Arizona, United States of America (32° 25.4328 N, 114° 34.7643 W, NAD 83 datum) [rufopunctata]  
TypesHolotype: USNM 4124
Lectotype: USNM 21846, designated by Derycke et al. 2020; paralectotypes (former syntypes): UIMNH 40750 (formerly USNM 21848), USNM 21846-21852, 21997, 21998 [rufopunctata] 
DiagnosisDIAGNOSIS (genus): Most closely related to Holbrookia and Callisaurus. Separable from the former by the presence of an ear opening, and from the latter by the presence of long spines projecting over the ear opening, and of a digital fringe with small subdigital scales between the fringe and the lamellae, as noted by Schmidt (1922: 651).
Two complete rows of larger frontal plates between the supraocular regions, never a single row anteriorly. Cephalic plates small; largest scales in supraocularregion rarely more than four times as large as the smallest. Femoral pores 18 to 47, usually more than 20. Digits and external margin of foot between fourth and fifth toes with fringes of narrow, elongate, projecting spines, largest on fourth toe and margin of foot, smaller on middle three digits, very small or lacking on first and fifth digits. In immature examples the fringe spines are proportionately shorter and broader at the bases. Males with two enlarged postanal scales.
Snout wedge-shaped in profile, with "countersunk" lower jaw. Form generally depressed, body rather flat, base of tail much depressed. Adpressed front limb not quite reaching base of femur; adpressed hind limb reaching beyond throat. Maximum total length 244 mm.; tail/total length ratio .49 to .64 (Heifetz 1941: 100). 
CommentSynonymy: Uma n. notata is more closely related to U. inornata than to U. n. rufopunctata (Wilgenbusch & de Queiroz 2000 and others). HEIFETZ (1941) synonymized U. rufopuncata with U. notata notata (which he distinguished from U. notata cowlesi). Populations formerly assigned to U. rufopunctata from the Mohawk Dunes, Yuma Co., AZ appear to represent a currently undescribed cryptic species (Trépanier and Murphy, 2001). Gottscho et al. 2016 concluded that U. rufopuncata is a hybrid between U. notata and U. cowlesi. However, Crother et al. 2017 find their results to be inconsistent, with some analyses supporting the status of U. rufopunctata as a separate species (although with introgression from both U. notata and U. cowlesi). Crother et al. 2017 therefore have retained U. rufopunctata pending further study. Derycke et al. 2020 confirmed that rufopunctata nestss within cowlesi but show different ranges for cowlesi and rufopunctata in their map (Fig. 1).

Type species: Uma notata BAIRD 1858: 253 is the type species of the genus Uma BAIRD 1858: 253.

Distribution: see map in Gottscho et al. 2016: Fig. 1, Derycke et al. 2020: 68 (Fig. 1). Not in Sonora fide Gotscho et al. and Lemos-Espinal et al. 2019.

Key: Norris 1958 presented a key to the species of Uma. 
EtymologyNamed after Notata (Latin) means known; rufopunctata (Latin, rufus "red" or "reddish" and punctus "pricked in") refers to the reddish color of the dorsal ocelli.
