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).
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. 
Etymologynamed after one of the collectors of the type, Drs. Ira L. Wiggins, H. M. Hill, and A. M. Vollmer.
