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).
