Conus fusololigusticus (Sacco, 1983)
The “Rhizoconus” virginalis var. fusuloligustica described
by Sacco (op. cit.: 115, pl. 11, fig. 4) from the Lower Pliocene of Bordighera
(Liguria) is reminiscent of C. villalvernensis n. sp. for the narrow W/H
= 0.48. However, Sacco’s taxon has a multispiral, planktotrophic protoconch
and shows only feeble undulations on the shoulder without any bead; it is here
regarded as a separate species (Conus fusoligusticus (Sacco, 1893),
lectotype here designated at Fig. 26 n-p) that differs from Brocchi’s taxon for
the architecture with conical spire and oblique internal side.
