Calviriidae Calviria Diagnosis
Calviriinae with a simple penis papilla pointing into the male atrium, which is provided with numerous spines. An accessory glandular organ with spines lies in front of the penis; this organ is not connected with the male atrium and has its own pore. A glandular complex is located medioventrally in front of the accessory organ. Secretory ducts run laterally from the accessory organ and open into two ventrolateral invaginations. With large subepidermal vesicles spread over the whole body.
