Taxonomy
Pseudunelidae was placed within the superfamily Strubellioidea in the taxonomy of Bouchet & Rocroi (2005).[5]
Pseudunelidae was subsequently placed within the (unranked) Hedylopsacea by Schrödl & Neusser (2010).[4]
Species
These are the different species in the genus Pseudunela:[6]
- Pseudunela cornuta (Challis, 1970) - type species of the genus Pseudunela, marine and temporary brackish[3]
- Pseudunela eirene Wawra, 1988 - The description of Pseudunela eirene is brief and based on a single specimen with ganglia of the nervous system and stylets of copulatory organs studied on a whole-mount by light microscopy only. No histological sections were made, and the radula was studied light-microscopically after dissolving the soft parts and stylets. Information on other organ systems is absent, and no further specimens are available for study.[7] Marine species.[8]
- Pseudunela espiritusanta Neusser & Schrödl, 2009[8] This species from Espiritu Santo Island in Vanuatu lives in brackish water[8]
- Pseudunela marteli Neusser, Jörger & Schrödl, 2011 - marine[3]
- Pseudunela viatoris Neusser, Jörger & Schrödl, 2011 - marine[3]
