|Diagnosis||Diagnosis. Elgaria velazquezi is separated from E. coerulea, E. multicarinata, E. cedrosensis, and E. paucicarinata by having a hatchling-juvenile color pattern consisting of immaculate, well-defined, pale-colored transverse bands on the neck, body, and anterior portion of the tail. It is separated from E. kinrgi,E. pananmintina, E. parva, E. cedrosensis, and E. paucicarinata by having strongly keeled dorsal scales. It can be further separated from E. coerulea and E. multicarinata by having a triangularly shaped lower subocular scale as opposed to having a squarish subocular; having black and white labial scales as opposed to having gray labials; and having black markings in the lateral fold as opposed to lacking them. It can be further separated from E. cedrosensis and E. paucicarinata by lacking a distinct, dark dorsal postorbital stripe (one of nine specimens of E. velazquezi has a faint postorbital stripe); having dark circular dorsal head markings in adults rather than randomly distributed, irregularly shaped blotches as in E. paucicarinata or having a nearly uni-color head as in many individuals of E.cedrosensis (one of nine specimens of E.cedrosensis has faint blotches on thehead); having bar-shaped, transverse blackmarkings in the lateral fold as opposed to a black reticulum; having bar-shaped,transverse and circular white markings inthe lateral body fold as opposed to having irregularly shaped white markings as in E.paucicarinata or having only circular white markings as in E. cedrosensis; and having the white markings of the lateral fold extending onto the lateral-most ventralscales.|
