AUSTRALIA • 80.1 mm; off Lady Elliot Island , Queensland; MJT ( Fig. 59J–K View Fig ) .

Geographical distribution and bathymetry

Australia (Queensland) and Coral Sea, at depths between 200 and 500 m.

Remarks

Shell moderately large to large (maximum shell length 103 mm), conical, with a low spire of concave profile. Early whorls project from an essentially flat spire, occasionally slightly domed. Last whorl with a characteristic very pale violet uniform color, especially in fresh specimens. Radular tooth ( Fig. 59M View Fig ) elongated, with the anterior section longer than the posterior section. The tooth is serrated with 40– 42 denticles arranged in one single row, splitting into two rows in the basal area towards the small terminating cusp. Barb well marked. Blade rounded, covering about one third of the anterior section of the tooth. Basal spur pointing upwards on top of the rounded base. Although initially introduced as a full species by da Motta (1985), it has usually been considered a subspecies or form of Conus (Klemaeconus) sugimotonis Kuroda, 1929 . In our phylogeny ( Fig. 2 View Fig ) the specimens of C. (K.) whiteheadae examined form a clade sister to C. (K.) plinthis . The specimens of C. (K.) sugimotonis from China are distinct by DNA, and belong to a clade which is sister to the one that includes C. (K.) plinthis and C. (K.) whiteheadae . Hence, our DNA data support C. (K.) whiteheadae as a full species rather than a form of C. (K.) sugimotonis , with a distribution area most likely restricted to the Coral Sea and its surroundings.
