Leonard, William P., Chichester, Lyle, Richart, Casey H. & Young, Tiffany A., 2011, Securicauda hermani and Carinacauda stormi, two new genera and species of slug from the Pacific Northwest of the United States (Gastropoda: Stylommatophora: Arionidae), with notes on Gliabates oregonius Webb 1959, Zootaxa 2746, pp. 43-56 : 45

Securicauda new genus

Type species. Securicauda hermani new species

Diagnosis. Distinguished from all other previously known arionids by small size, strongly keeled tail, and a mantle covering approximately 70% of the extended body length and from Carinacauda stormi by the absence of an atrium, the presence of a very short epiphallus partially embedded in the penis and by the lack of atrial accessory structures.

Etymology. The generic name is derived from Latin securis, meaning axe, and cauda, meaning tail. It describes the sharp, blade-like keel of the animal’s tail.
