Caenoplana
Caenoplana is a genus of land planarians from Australia and New Zealand.

Description 
The genus Caenoplana is characterized by having an elongate, cylindrical to sub-cylindrical body. The eyes are arranged along the body margins, crowded irregularly at the sides of the anterior end and extending in a single row to the posterior end. The copulatory apparatus lacks a permanent penis, i. e., the penis is formed during copulation by folds in the male cavity. The female cavity is irregular and narrow and the ovovitelline ducts join each other behind it, entering it ventrally.
