Kohniconus duerri (Petuch, 1994)

 

 

Description (3): Shell of average size for subgenus, elongated, wide across shoulder, with relatively low spire; shoulder sharply-angled, carinated; shell smooth and polished, with 8 wide, impressed spiral sulci around anterior tip; aperture narrow throughout; color pattern (when preserved, as on holotype) composed of 3 bands of large, oval dots, with central band being widest; early whorls coronated.

Holotype: UF66422, Length 38 mm.

Type Locality: Pinecrest Beds Fauna (Kissimmee River Valley only), from Kissimmee River dredging at Fort Basinger, Highlands County.

Remarks: Conus duerri is most similar to the contemporaneous Pine-crest C. presozoni Olsson and Petit, 1964 (Plate 92, Figure A), but differs in being a smaller, broader, and less elongated shell with a flatter spire and carinated shoulder. The new species is endemic to the Kissimmee Embayment.

Etymology: Named for Mr. Richard Duerr of Hollywood, Florida.



Secondo Hendricks, il Conus duerri non sarebbe altro che un Conus delessertii(1).
