Which family historically housed species now in *Cheiracanthium*?
Answer
Clubionidae
Historically, many spider species that are now placed under the genus *Cheiracanthium* were commonly grouped within the family Clubionidae, often referred to generally as the sac spiders. Recognizing this former placement is vital when interpreting older scientific literature, as taxonomic refinement is a continuous process in biology. The shift reflects a deeper, evidence-based understanding of their evolutionary history, indicating that *Cheiracanthium* possesses traits that distinguish it sufficiently from the rest of the older Clubionid grouping.
