Comment | Belongs to the S. magister complex. Grismer and McGuire (1996) concluded that an interbreeding continuity of populations, often referred to as S. monserratensis, S. rufidorsum, and S. zosteromus, extends throughout most of Baja California; hence they are conspecific (as was thought by Smith, 1939). Grismer (2002) regarded the three populations as pattern classes rather than subspecies. Pavón-Vázquez et al. 2024 found that S. z. zosteromus and S. z. monserratensis are not evolutionarily independent. In contrast, S. z. rufidorsum appears to be divergent. However, given their limited sample sizes and previously published patterns of morphological and molecular variation (Grismer and McGuire 1996), they treat S. zosteromus as monotypic, without having valid subspecies. Distribution: see Pavón-Vázquez et al. 2024 (Fig.1) for a map, including the formerly recognized subspecies. |
Etymology | Named after Greek zoster, "belt or girdle," and the Latin suffix –ome, "pertaining to the nature of," refer to the black inguinal blotches anterior to the thighs, connecting with black areas on the venter. Etymology (monserratensis): This taxon is named for its island type locality. Etymology (rufidorsum): The Latin nouns rufus, "red, reddish," and dorsum, "back" refer to the rusty-red dorsal stripe. |
