A Taxonomic Study of the Middle American Snake, Pituophis deppei

This study dives into the biology of a Central American snake, tracing its variations across the Mexican state of Michoacán and beyond. The author’s fieldwork uncovered two previously thought‑separate subspecies living side by side, prompting a thorough review of museum collections from institutions across the United States. By comparing fresh observations with historic specimens, the research paints a clearer picture of how these populations relate to one another.

The paper focuses on measurable traits such as ventral and caudal scale counts, as well as coloration patterns that have long guided taxonomic decisions. A concise historical overview tracks the shifting names and classifications that have surrounded the species since the 19th century. Detailed tables and a couple of illustrative plates accompany the text, offering listeners concrete visual references while illuminating the subtle differences among the recognized subspecies. The work stands as a valuable reference for anyone interested in reptile diversity and the meticulous process of scientific classification.
