The genus Obelus currently contains seven living species from the Canary Islands and Morocco and at least six additional fossil species from the Neogene of Fuerteventura (of the latter, only O. heiligorum, is scientifically named). Obelus shares with the genera Cochlicella, including the subgenus Prietocella, and with Monilearia, including the subgenus Lyrula, the presence of a very characteristic vaginal appendage which differs in anatomical details among these taxa. We here describe a new species, O. zarzaensis, from the Jandía Peninsula (Fuerteventura, Canary Islands) and compare it with similar species from the Canary Islands. Furthermore, a new subgenus, Grohiellus, is proposed which differs from Obelus s. str. by a relatively long A2 section of the vaginal appendage with a vestigial blind sac and by a long flagellum which is only slightly shorter than the epiphallus.

More about this publication?
  • Archiv für Molluskenkunde is an international, peer-reviewed journal on all aspects of molluscan biodiversity. It preferably publishes original research papers of high quality on systematics, taxonomy, phylogeny and morphology of all groups of molluscs, both recent and fossil from the Cenozoic. Contributions of broad international interest on other aspects of malacology such as ecology and biogeography are welcome as well. Papers on physiology, parasitology, regional faunistics or those on non-Cenozoic fossils or pure biostratigraphy should be submitted elsewhere. Manuscripts shall be in English but may include an expanded abstract in a foreign language.

    Archiv für Molluskenkunde was founded in 1868 as "Nachrichtsblatt der Deutschen Malakozoologischen Gesellschaft". It has been published continuously since its foundation, making it the oldest malacological journal. It is edited by the curators of the section of Mollusca at the Senckenberg research institute.

    Up to and including Vol. 138/2 papers were published under the ISSN 0003-9284.
