Conus (Kohniconus) delessertii (Rècluz, 1843)
Conus (Konhiconus) delessertii bermontianus (Petuch & Mardie Drolshagen, 2011)
Il Conus sozoni è un sinonimo di questa specie (3).
Range: Bermuda, South Carolina to Key West and the Gulf of Mexico
Comments: Kohniconus delessertii is a well-known species that is unlikely to be confused with any other West Atlantic species. Besides differences in radular morphology (Tucker & Tenorio, 2009; compare Figs. 124-17 & 18 to Figs. 124-1, 3, 14, & 15), Kohniconus speciesdiffer from Gradiconus in having the nodules on the early spire whorls better developed (3).
Original Description (from Récluz, 1843, p. 2-3):
"Testa turbinata, basi transverse sulcata, roseo-fuscescente aut lutescente, punctis quadratis castaneis interdum confluentibus oblique perlongum flammulata, albo in medio bifasciata: fasciis punctis castaneis quadratis tessellatis; spira conico-acuta, elongata, gradatim digesta, late canaliculata, luteo-aurantia, castaneo flammulata; anfractibus 13 ad 14 basi carinatis: carinis albis, spadiceo articulatis, supremis granulatis; apertura alba, roseo trifasciata. — Long., 62, larg., 30, haut. de la spire, 25 millimètres.
Habit, la Mer Rouge, près des côtes de l'île de Socotora. ERRATO: Cape Canaveral, Florida
Je fais hommage de cette belle et rare espèce à M. le baron Benjamin Delessert."
E’ una conchiglia dal guscio liscio e brillante, solcato verso la base da scanalature oblique poco profonde e da leggere strie di accrescimento presenti su tutto l’ultimo giro. La superficie è di colore rosa, rossastro o giallastro, ricoperta di punti di forma circa quadrata e di colore marrone, che talvolta confluiscono a formare macchie a forma di fiamma longitudinali o oblique. Queste flammule sono interrotte, verso la metà dell’ultimo giro, da due fasce bianche, lungo le quali sono presenti linee spirali di punti di forma circa quadrata, anch’essi di colore marrone. La spira è conica, allungata ed acuminata, formata da tredici – quattordici spire canalicolate e carenate. I primi giri sono granulati. L’apertura è allungata, bianca e brillante, con tre fasce di colore rosa all’interno. Il labbro è leggero, affilato e fortemente arretrato alla sommità (1).
