DistributionUSA (Washington, Oregon, California, Nevada, W Utah),
Mexico (N Baja California Norte, Isla de Cedros)

biseriatus: S Idaho, southwest through Nevada and W Utah into California and the San Pedro Mártir Range in Baja California. Type locality: Borders of El Paso Creek and Tejon Valley. Restricted to El Paso Creek by SMITH & TAYLOR 1950. (El Paso Creek is in Kern Co., about ten miles
northeast of Ft. Tejon).

bocourti: USA (California). Type Locality: Restricted by Bell (1954), through lectotype designation, to Santa Cruz, Santa
Cruz Co., California.

longipes: Type Locality: Fort Tejon, California [Kern County].

taylori: Type Locality: Half-way between Merced Lake and Sunrise Trail (Echo Creek Basin), elevation 7500 feet, Yosemite National Park, California.

Type locality: “California and probably Oregon”; restricted to “Benicia, Solano County, California” by GRINNEL & CAMP 1917 Map legend:

TypesSyntypes: USNM 2838, 2866, collected by Dr. J. S. Newberry during the U. S. Exploring Expedition in 1838-1842. No. 2838 is lost, and until 1996 No. 2866 was also thought to be lost (as implied by its absence in Cochran's 1961 list). Accordingly, Bell (1954) designated a neotype, MVZ 59874, collected by Robert C. Stebbins. After discovery of the existence of USNM 2866 (two syntypes), Bell et al. (2001) petitioned the International Commission on Zoological Nomenclature for acceptance of the designated neotype as the name-bearer, rather than the rediscovered syntypes, as required by the Code (ICZN, 1999).

Lectotype: ANSP 8476 (Bell, 1954), collected by Dr. Heermann [biseriatus]

Lectotype: BMNH 1946.9.6.98 (formerly 1885.11.5Santa Cruz, California, designated by Bell (1954) [bocourti].

Syntypes: (3) ANSP 8477-79; California, Tejon Valley, El Paso Creek [azureus]

Lectotype: USNM 4358A, collected by John Xantus, designated by Bell (1954); SYNTYPE: UIMNH 40726 [longipes]

Syntypes; Four: USNM 8612, collected by Yarrow in 1872 [Sceloporus smaragdinus COPE in YARROW 1875]

Holotype: MVZ 5947, collected by Walter P. Taylor, 25 August 1915 [taylori] 
CommentSubspecies: S. o. becki has been elevated to full species.

Types: The Commission of Zoological Nomenclature has designated a neotype for Sceloporus occidentalis from the west coast ranges of North America. The neotype, originally designated in 1954, is a well preserved adult specimen of known provenance and replaces two missing syntypes which have recently been rediscovered but which are immature specimens and do not distinguish S.
occidentalis from closely related taxa (Opinion 2024, Bull. Zool. Nomencl.).

Sceloporus smaragdinus COPE in YARROW 1875: 572 is a junior primary homonym of S. smaragdinus Bocourt (1873).

S. o. longipes is the form sympatric with S. undulatus tristichus in the Pine Valley
Mountains of southwestern Utah (Cole, 1983; Smith and Chiszar, 1989). 
EtymologyEtymology (azureus): This adjective is Latinized from the French azur, "a blue color," and refers to the blue color of the dorsal scales of the syntypes.

Etymology (biseriatus): The name is an adjective from Latin bis-, "two," and series, "series," and refers to the two, or double, dorsolateral light lines.

Etymology (bocourti): The Latinized noun in the genitive singular honors Marie-Firmin Bocourt, a French herpetologist most widely known for his major contributions to the “Mission Scientifique au Mexique”.

Etymology (longipes): The Latin long, "long," and pes, "foot," refer to the elongate toes.

Etymology (occidentalis): The Latin words occidens, "the west," and -alis, "pertaining to," are the bases for the nominal species.

Etymology (taylori): The Latin genitive singular noun honors the collector, Walter P. Taylor, widely travelled in the early twentieth century in Mexico as well as the United States as a member of the U. S. Fish and Wildlife Service.
