Sabaconidae
sabaconid harvestmen
Sabaconidae is a family of harvestmen (Opiliones: Dyspnoi) comprising approximately 50 described species. The family exhibits a disjunct distribution spanning eastern North America and temperate Eurasia, with notable diversity in the southern Appalachian Mountains and the Altai Mountains of Russia. Species-level taxonomy within the family has been complicated by cryptic diversification, particularly in widespread species such as Sabacon cavicolens, which shows evidence of multiple allopatric lineages separated by vicariance and rare long-distance dispersal events.
