Original description: Petite Lithamphora à trois segments. Céphalis et thorax soudés avec tube vertical incliné sur le thorax. Abdomen rétréci en tube très court avant l'ouverture. Cette espèce se distingue de la précédente, dont elle est peut-être l'ancêtre, par une suture lombaire plus nette et une ouverture non rétrécie.
