SSAR 9th Edition Comments:
The taxonomic distinction between populations of X. riversiana on San Nicolas Island (X. r. riversiana) and those on San Clemente and Santa Barbara Islands (X. r. reticulata) has been supported by analyses of both DNA sequences (Noonan et al., 2013, Molecular Phylogenetics and Evolution 69: 109–122) and morphology (Adams et al., 2018, Copeia 106: 550–562; Grismer et al., 2022, Vertebrate Zoology 7: 1–27).
Range maps are based on curated specimens and provided gratis by CNAH.
