Description: Shell of small size for the genus, conical, slightly turriculate, rather solid, holotype 5.4 mm high, 4.6 mm wide. Usually 5–5.5 mm , rarely up to 6.5 mm in height, 4–4.5 mm in width. Protoconch smooth, 240–250 µm in diameter, about 1.7 whorls. Teleoconch comprising 4.5–5.5 whorls; teleoconch whorls slightly convex, with 6–8 regularly spaced, fine, incised spiral lines. Basal cord rounded and divided by one or two fine threads, generally the upper one more pronounced, resulting in parallel cordlets. Suture distinct. Teleoconch surface covered by faint prosocline growth striae. Base convex, with 9–11 concentric fine incised spiral lines, irregularly spaced and crossed by numerous growth striae. Umbilicus closed also in juveniles covered with a white callus. Aperture quadrangular with a columellar callus thickened in the middle portion. Interior of the aperture iridescent whitish. Colour of protoconch and early teleoconch whorls bright red, remaining whorls and base red-brownish, with axial opisthocline brown-reddish narrow bands. Three to five narrow yellowish-orange spiral bands covering the teleoconch. Yellowish-orange bands increasing in number (5–6) on the teleoconch base, and alternate with 4–5 red-brownish concentric spiral bands, resulting in a red spotted pattern. FIGURE 3. 1–5.

Type material: Ninety shells, including juvenile stages and subadults, from the type locality. Holotype : MNHN 25882; paratype 1: MZB 49669; paratype 2: MCZR 00226; paratypes 3–54: CS-PM; paratypes 55–59: MO; paratypes 60–89: PT. Etymology: The species name is after Piergiorgio Trillò, friend and SCUBA diver who provided the marine sediment in which the new species was found. Locus typicus: Talbot Bank ( 37°30’00”N , 11°40’00”E ), infralittoral bottom, at a depth of 25 m , Sicily Channel, Mediterranean Sea. Distribution: Only known from the type locality.
