Spermophilus adocetus Merriam 1903 Spermophilus adocetus Merriam 1903, Proc. Biol. Soc. Wash., 16: 79. Type Locality: "La Salada, 40 miles [64 km] south of Uruapan, Michoacan, Mexico.". Vernacular Names: Tropical Ground Squirrel. Subspecies:: Subspecies Spermophilus adocetus subsp. adocetus Merriam 1903 Subspecies Spermophilus adocetus subsp. infernatus Alvarez and Ramírez-P. 1968 Distribution: E Jalisco, Michoacan, and N Guerrero (WC Mexico). Conservation: IUCN – Lower Risk (lc). Discussion: Subgenus Notocitellus (A. H. Howell, 1938) or Otospermophilus (Hall, 1981:399); but see also Birney and Genoways (1973) who suggested it is closer to subgenus Ictidomys. Molecular sequence data indicate that adocetus and annulatus are sister species (Harrison et al., 2003), and basal to all other spermophiline ground squirrels, except Ammospermophilus.
