Introduction: Systematics of the subterranean amphipod genus Stygobromus (Crangonyctidae): Species of the Ozarks and adjacent regions
ABSTRACT:
This paper serves as an introduction to a multi-part monograph on the systematics of the subterranean amphipod genus Stygobromus, originally initiated by the late Dr. John R. Holsinger. The manuscript, left incomplete at the time of his death in 2018, was substantially completed and prepared for publication by the author, Julian J. Lewis, as a tribute to Holsinger’s lifelong contributions to subterranean biology. This first installment focuses on Stygobromus species from the Ozark, Arbuckle, and Ouachita mountains, extending into the glaciated plains of the central United States. The paper outlines the historical context of the work, the methodological challenges in preparing a decades-old manuscript for modern publication, and the taxonomic scope of the species treated. Special attention is given to preserving Holsinger’s original taxonomic intent and style, while acknowledging the limitations of pre-genetic systematics and the potential for cryptic species. This work represents a significant step toward completing Holsinger’s vision of a comprehensive treatment of Stygobromus systematics across North America.
