Species / Harpodactylus Marolti

Harpodactylus Marolti

Stromboidea


Original Description of Harpodactylus marolti by Kollmann, 2009:

  • "The shells are large and the spire broadly turriculate. The whorls possess a broad, inclined subsutural ramp which is delimited by an acute angulation. The abapical whorl face is slightly oblique towards the shell axis. The sculpture consists of spiral threads and irregular fold-like opisthocline collabral ribs which form irregular nodes at the angulation. The last whorl is about 2/3 of the total height. The abapical whorl face is concave. The angulations towards the subsutural ramp and the concave base bear strong ribbons. A third ribbon is located in the middle of the abapical whorl face. There are also traces of spiral threads preserved. The rostrum is strongly bent. The ribbons extend to the broadly expanded wing where the middle one splits into two or three. These and the ribbons emerging from the angulations extend into spines at the margins of the wing."
