A Taxonomic Study of the Middle American Snake, Pituophis deppei

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.

About the Author

Duellman, William Edward portrait

William Edward Duellman

William Edward Duellman is a prominent herpetologist known for his extensive research on amphibians and reptiles, particularly in Central America and Mexico. His work has significantly contributed to the understanding of the biodiversity and taxonomy of these species. Among his notable publications is "A Distributional Study of the Amphibians of the Isthmus of Tehuantepec, México," which highlights the unique amphibian populations in that region. Duellman's research not only aids in the classification of various species but also emphasizes the importance of conservation efforts in their native habitats.
