Carinacauda new genus

Type species. Carinacauda stormi new species

Diagnosis. Distinguished from all other previously known arionids by small size, strongly keeled tail and a mantle covering approximately 60% of the extended body length; distinguished from Securicauda hermani by the presence of an atrium, a very long and coiled epiphallus and a pair of atrial accessory structures.

Etymology. The name refers to the keeled morphology of the tail; carina is Latin for keel, cauda for tail.
