Remarks.

Suriano (1980) described the species as Notodiplocerus singularis and the original drawings are simplified lacking important details of the morphology of these unique anchors that characterize the genus. In the description provided by Rossin and Timi (2016), the morphology of the dorsal anchor complex and copulatory complex was described in detail and illustrated by means of drawings and photographs. The morphology of the present material is in agreement with the material studied by Rossin and Timi (2016).
