DistributionUSA (S California),
Mexico (Baja California)

Type locality: arroyo 9 miles east of Miller'sLanding, Distrito del Norte, Baja California, Mexico.  
TypesHolotype: CAS-SUR 11564 
DiagnosisDiagnosis: A subspecies of X. vigilis intermediate between the typical form and X.v. gilberti. Differs from the other forms as follows: (1) ventrals usually less than 29, 25 (27.4) 29; (2) dorsal pattern of numerous small, discrete spots, never fused to form blotches or lines; (3) tail with dark spots restricted to tips of scales (from SAVAGE 1952).

DEFINITION. Dorsal scales 31-38 (34.3); 4th toe lamellae 16-20 (17.9); femoral pores 4-9 (6); ventrals 25-29 (27.4); 7th supralabial usually not as high as 6th. Tail spots generally restricted to tips of scales; dorsal spots (when present) numerous
and small, often occupying only one scale; dorsolateral light stripes often present on body. (Bezy 1982) 
CommentHybridization: X. wigginsi intergrades with X. vigilis gilberti (SAVAGE 1952: 476).

Distribution: In Jones & LOVICH 2009:440 the distribution map for Xantusia wigginsi erroneously includes the ranges for X. sherbrookei and X. gilberti. See map in Bezy et al. 2019: 27 (Fig. 10). 
EtymologyNamed after one of the collectors of the type, Drs. Ira L. Wiggins, H. M. Hill, and A. M. Vollmer.
