03DE87F5A4686E503ED0FEAEFD56FC93.taxon	description	(Plate 1, Figs 1 – 3) Description Shell slender, fusiform, reaching about 18 mm in length, width about 29 % of length. Protoconch consists of 2 to 2.5 glassy, conoidal whorls. Teleoconch consists of up to 9 slightly convex whorls. Slightly convex spire outline. Ten to twelve axial ribs on first whorls, increasing to 26 to 28 ribs on penultimate whorl and 36 to 38 ribs on body whorl. Nine to ten spiral grooves on the penultimate and 20 to 22 spiral grooves on the body whorl divide the interspaces, giving them a slightly cancellated appearance. Aperture shorter than half the entire shell, lirate inside. Lip slightly rounded and recurved towards the siphonal fasciole. Siphonal canal short, wide and slightly recurved. Columella with 4 strong folds, decreasing in size anteriorly. Folds merge into spiral cords when leaving the columellar shield. Colour pattern: Protoconch and first two to three whorls light brown, remaining whorls white with dark brown dots fading at the margins to lighter brown on the posterior third of the whorls, followed by a completely white area and an interrupted brown line at the periphery of the whorls. Body whorl with pinkish areas in the brown-spotted zone and nearly completely pinkish in the anterior half, where small brown streaks are also present. Aperture and columellar folds whitish to slightly pinkish.	en	Herrmann, Manfred, Salisbury, Richard (2012): A new species of Vexillum (Costellaria) (Gastropoda: Costellariidae) from the Marquesas with remarks on Mitra chariessa MELVILL, 1888.

03DE87F5A4686E503ED0FEAEFD56FC93.taxon	etymology	Etymology: Named after Germaine Gourguet, wife of Robert Gourguet. For her passion and long years of work on the malacological fauna of French Polynesia. She has collected several samples of new species. This is dedicated to her in recognition of her extreme patience.	en	Herrmann, Manfred, Salisbury, Richard (2012): A new species of Vexillum (Costellaria) (Gastropoda: Costellariidae) from the Marquesas with remarks on Mitra chariessa MELVILL, 1888.

03DE87F5A46C6E523ED0FD1EFD0AFA39.taxon	discussion	In Turner (2001) Mitra chariessa MELVILLL, 1888 (Fig. 8) was synonymized with Vexillum (C.) rubellum (ADAMS & REEVE, 1850) (Figs 9 – 10), but when comparing the type species in NMW with the new species, the authors realized that M. chariessa should be synonymized with Vexillum (C.) scitulum (A. ADAMS, 1853) instead. The type of M. chariessa and the syntypes of V. (C.) scitulum have the same slender appearance, an identical cancellated surface with a more prominent second spiral cord below the suture and the same colouration. The holotype of M. chariessa and the larger syntype of V. (C.) scitulum are nearly completely faded, but on close examination, slightly brown faded dots can be seen on the periphery of the body whorl of both shells. This characteristic can be better seen on the smaller syntype in the NHMUK. In contrast, V. (C.) rubellum differ from the mentioned types. This species is larger, the axial ribs are thicker and, as mentioned by Adams & Reeve (1850) in the original description, V. (C.) rubellum has more swollen whorls and the longer siphonal canal is significantly recurved.	en	Herrmann, Manfred, Salisbury, Richard (2012): A new species of Vexillum (Costellaria) (Gastropoda: Costellariidae) from the Marquesas with remarks on Mitra chariessa MELVILL, 1888.
