Abstract

Based on four specimens from off Norway, a description of a new species is given. The internal anatomy differs from all Solenogastres known so far. The species is characterized by two different types of spicules, a monoserial radula with three denticles per tooth, and very long salivary gland organs of special structure. For this reason a monospecific genus is introduced. Helluoherpia aegiri gen.n. et sp.n. corresponds with the diagnosis of the family Dondersiidae. Helluoherpia aegiri gen.n. et sp.n. wird anhand von vier Individuen aus verschiedenen Aufsammlungen vor der Küste Norwegens beschrieben. Die Art zeichnet sich durch zwei Typen von Spicula, eine monoseriale Radula mit drei Dentikeln pro Zahn und lange Vorderdarmdrüsenorgane von besonderem Bau aus. Da die innere Organisation der Tiere von allen bisher bekannten Solenogastres-Arten stark abweicht, wird eine neue Gattung aufgestellt. Den diagnostischen Merkmalen nach ist Helluoherpia gen.n. eindeutig in die Familie Dondersiidae zu stellen.
