On the Calviriidae Martens and Curini-Galletti, 1993 (Platyhelminthes, Proseriata), with the description of three new species
Three new species of Calviriidae are described, belonging to two new genera: Diskeria gigantea n.g. n.sp., D. tasmanica n.sp. and Paracalviria islandica n.g. n.sp. The species of Diskeria have a copulatory organ with two rings of needles of which the internal ring forms a structure resembling a styl...
