Caddo pepperella

Shear, 1975

Caddo pepperella is a of (: Caddidae) described by Shear in 1975. It occurs in North America and is 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 Caddidae, it belongs to the suborder Eupnoi and possesses the characteristic elongated body form and reduced typical of this harvestman family.
