A definitive study of a little‑known group of freshwater crustaceans.
This book revises the genus Stygonectes, the largest group of North American subterranean amphipods, and explains how species are distributed and how they may have speciated.
This work compiles all available collections and literature to clarify taxonomy, map distribution patterns, and build a model for evolutionary change in this hidden world. It situates Stygonectes within the wider context of Crangonyx‑section amphipods and highlights the gaps in our knowledge about ecology and life history for subterranean species.
- A thorough taxonomic revision based on extensive collections and literature.
- Detailed discussions of species distributions and the barriers that shape them.
- New species descriptions and clarified relationships within the genus.
- A proposed framework for understanding speciation in subterranean freshwater amphipods.
Ideal for readers of invertebrate taxonomy, cave biology, and zoogeography who seek a rigorous, data‑driven look at how underground species evolve and persist.
