Caddo agilis
Caddo agilis is a species of harvestman (Opiliones) in the family Caddidae, first described by Nathan Banks in 1892. It exhibits a disjunct distribution spanning North America and Japan, a pattern shared with its congener Caddo pepperella. Phylogenetic evidence indicates these two species diverged before acquiring their current geographic ranges, suggesting the disjunction resulted from vicariance rather than recent dispersal. The species belongs to a small family of harvestmen characterized by distinctive morphological features.
Caddo pepperella
Caddo pepperella is a species of harvestman (Opiliones: Caddidae) described by Shear in 1975. It occurs in North America and is sympatric with the closely related Caddo agilis. Phylogenetic studies indicate that C. pepperella and C. agilis diverged before acquiring their current disjunct distributions in North America and Japan. Like other members of the family Caddidae, it belongs to the suborder Eupnoi and possesses the characteristic elongated body form and reduced eyes typical of this harvestman family.
