About This Book

The study examines 124 museum and field specimens from Middle America to assess variation and relationships within a pituophis complex. It reviews earlier names and compares scale counts (ventrals 210–246, caudals 52–72), sexual dimorphism, and dorsal coloration patterns characterized by tan ground color, middorsal blotches and lateral intercalary spots, including geographic shifts where anterior blotches divide into paired stripes. Analysis reveals sympatric populations representing distinct species, leading to taxonomic rearrangement and recognition of species and subspecies with diagnoses, distribution maps, tables of measurements, and illustrative figures.
