Diagnosis. Males of Actinopus pampa resemble all other species of group tutu, except A. itacolomi and A. longipalpis, by PA continuous to PI. They resemble those of A. azaghal, A. longipalpis, and A. pindapoy by BTA dorsally on the embolus apex and differ from all other species of the genus by a depression at embolus base. Females resemble those of A. tutu and A. azaghal by subquadrate shape of receptacles, composed of a unique lobe but Males differ from those of pore distribution reaching 75% of receptacles length. They further differ from A. itacolomi by receptacles with tapered apex and lateral swellings.
