A multi-layered approach uncovers overlooked taxonomic and physiological diversity in Alpine subterranean spiders (Araneae: Linyphiidae: Troglohyphantes)

The integration of multiple lines of evidence in the delimitation of taxa is becoming the gold standard in modern taxonomy and systematics. However, multi-layered taxonomy is still incipient when it comes to species description within a mega-diverse group of organisms (e.g. arthropods), especially t...
