Evolution du noms au WORMs
J'ai gardé la trace de l'ancienne identification en la reportant dans le texte.

Très belle espèce et aussi très variable que je mettrais dans le genre Floraconus. Mais mon ami Tenorio lui la met dans les Ketyconus...

Effectivement, on la trouve dans les Ketyconus :

Conus tinianus Hwass in Bruguiere, 1792

Geographic Range:-Cape Agulhas, RSA - Mozambique
Habitat:-Shallow Water
Description:-Source Iconography
Shell light, thin and moderately small (usually about 50 mm long), dull, with convex sides, smooth except for weak spiral ridges near the anterior end. Shoulder rounded or roundly angled, very finely striated shoulder slope. Spire moderately high, with a slightly concave profile, although the individual whorls are convex, often stepped. The body whorl is purplish brown, orangish or red in form aurora, often (but not always) covered with irregular dark brown blotches that may occasionally form broad irregular bands. The spire is of the same color as the body whorl. Aperture violet in most brownish specimen, but light orange or pink in orangish or red specimens. The animal is orange, densely mottled with tiny white dots.
Discussion:-C. tinianus may be compared with C. ardisiaceus Kiener, 1845, from Oman, which, however, has a broader more ovate shell and a coarser spiral sculpture on the sutural ramps. C. anemone Lamarck, 1810, from Australia, often has a larger shell, with a coarser sculpture; C. papilliferus Sowerby I, 1834, from Eastem Australia, on the other hand, is smaller, with a broader and more angulate shoulder.
In South African waters, the closest species is C. mozambicus Hwass in Bruguiere, 1792, from which it is readily separated by the finely striated shoulder slope. The name aurora corresponds to a form of C. tinianus, which is applied to orange specimens with a pattern reduced or even absent.
