APPLICATION OF THE NAMES CNEMIDOPHORUS-TIGRIS-DISPARILIS AND CNEMIDOPHORUS-TIGRIS-PUNCTILINEALIS TO VALID TAXA (SAURIA, TEIIDAE) AND RELEGATION OF THE NAMES CNEMIDOPHORUS-TIGRIS-GRACILIS AND CNEMIDOPHORUS-TIGRIS-DICKERSONAE TO APPROPRIATE SYNONYMIES

Historical and multivariate evidence indicate that the type specimen o f Cnemidophorus tigris gracilis Baird and Girard, 1852, is a represent ative of C. t. tgris Baird and Girard, 1852, with the latter name havi ng priority. Initially, C. disparilis Dickerson, 1919, and C. punctili nealis Dickerson, 1919, both described from Isla Tiburon, Gulf of Cali fornia, appeared to be available for populations currently allocated t o C, t. gracilis. However, we identified the holotype of C. disparilis as a representative of C. t, dickersonae Van Denburgh and Slevin, 192 1. In addition, we corroborated an earlier identification of the two p aratypes included in the type series as representatives of C. cataline nsis from Isla Santa Catalina, Gulf of California. It is evident that material from three sampling localities was inadvertently mixed prior to the description of C. disparilis. Therefore, C. t. disparilis has p riority over C. t. dickersonae, and the type locality of C. t. dispari lis is corrected to Isla Angel de la Guarda, Gulf of California. This leaves C. t. punctilinealis as the provisional name for populations pr esently allocated to C. t. gracilis.
