Shell small, pyriform, more or less minutely wrinkled throughout; spire elevated; dorsal sulcus often well defined; columellar and labral dentition numerous and well-defined. Dorsal colouration white or light red but more often light green with anterior tip usually red.</p><p>Remarks. Eight fossil and nine living species of the Indian Ocean, Indo-Pacific and Pacific are assigned to the genus.</p><p>Liltved (2000) accepted only the genus Erato Risso, 1826 for all the recent Eratoid species that are similar to the Cypraeidae and Triviidae . Meyer (2003, 2004), however, has confirmed a much greater diversity in genera within the Cypraeidae . Similar results were found in the family Ovulidae (Schiaparelli et al. 2005) and in Triviidae, the sister family of the Eratoidae (Simone 2004; Fehse &amp; Grego 2009a,b). There are no molecular systematic data for the Eratoidae available at the moment but the zoogeography alone implies a greater diversity of genera by geographical isolation (Schilder 1943, 1959, 1961, 1969). It is already confirmed by their shell morphology. Similarly, the genus Erato – type species Voluta cypraeola Brocchi, 1814 – is only used for European fossil and recent species (Schilder &amp; Schilder 1971). Species of Erato have generally a larger shell. Some Erato species might have a pustulated but never wrinkled shell and the pustules are restricted usually to the posterior part of the shell. A dorsal sulcus is obscured or absent in almost all species (Fehse &amp; Landau 2002a, b, 2003; Fehse &amp; Grego in press). Furthermore, the only living species of the genus Erato – E. ooluta (Montagu, 1803) – is uniformly coloured and lacks, therefore, a different coloured anterior tip.</p></div>	https://treatment.plazi.org/id/03C8879BC26B750EFEFFEB44FC71FE5D	Public Domain	No known copyright restrictions apply.

Empty shells were dived in depths of 5-35 m in rubble at all mentioned localities. – Holotype: Off barrier reef of the atoll of Makemo, Tuamotu, French Polynesia; length: 4.0 mm; width: 2.3 mm; height: 1.8 mm; LT 30; CT 21 (ZSM, coll. No. 20091000) . — Paratypes: No. 1: barrier reef of the atoll of Makemo, Tuamotu, French Polynesia; length: 3.7 mm; width: 2.1 mm; height: 1.6 mm; LT –; CT – subadult (DFB, No. 9233); No. 2: Off Motu Otepipi, Rangiroa, Tuamotu, French Polynesia; length: 3.7 mm; width: 2.0 mm; height: 1.5 mm; LT 25; CT 19 (DFB, No. 9234-1); No. 3: Off Motu Otepipi, Rangiroa, Tuamotu, French Polynesia; length: 3.1 mm; width: 1.8 mm; height: 1.4 mm; LT –; CT – subadult (DFB, No. 9234-2); No. 4: Off Motu Otepipi, Rangiroa, Tuamotu, French Polynesia; length: 3.3 mm; width: 2.0 mm; height: 1.6 mm; LT 22; CT 18 (JLT). Further paratypes in collection DFB, J. Letourneux and R. Gourguet.</p><p>Description</p><p>Shell small, fragile, slender, elongated, almost cylindrical with a short, conical spire. Protoconch consisting of 1-1 ½ whorls with a very small nucleus. Suture indistinct and only visible through the translucent shell. Junction with teleoconch not clearly defined. Teleoconch comprising 2 ½ -3 flat-sided whorls. Body whorl about 95 % of total height, slender, elongated, almost cylindrical, with the maximum diameter almost centrally. Dorsum finely granulated, rounded, with an incised dorsal sulcus and not constricted behind the anterior extremity. Aperture very narrow and straight, 85-90 % of total height. Labrum weakly thickened, almost straight, bearing up to 30 fine and equal denticles on the inner margin, which do extend onto the lip as very fine folds. Siphonal canal short, rounded and straight.Columella smooth, slightly sinuous, bordered internally by a weak carinal ridge. The ridge is slightly stronger in the fossular area and slightly protruding. Parietal lip roundly thickened, bearing up to 21 weak denticles. The most anterior 2-4 denticles are developed into unusually short folds, which run obliquely across the ventrum. Fossula marked by a weak concavity. Terminal ridge simple and strong running along the border of the siphonal canal.</p><p>Shell colour translucent white with a light red clouding and a broad transverse white band on the dorsum. Anterior labral tip red, anterior ventral tip very indistinct red.</p><p>Variation: The dorsal sulcus is not developed in juvenile specimens and the shell is smooth. Subadult specimens are covered with more callous where the sulcus is already incised and the granulation slightly developed. Matured shells show a deeply incised sulcus, the granules and the dentition are fully developed. The number of labral teeth varies between 22 and 30 and the number of columellar teeth between 18 and 21. The ratio width to length is in average 58 % but varies between 55 % and 61 %.</p><p>No information is available on external morphology and radula.</p><p>Etymology. In honour to Robert Gourguet, Tuamotu, who provided sufficient material to describe this taxon.</p><p>Distribution. The new species is confirmed by paratypes in the author’ s collection besides the type locality also from Rangiroa, Tuamotu; Pt. Venus, Tahiti; Marpi, Saipan and Periki, Jawa, Indonesia.</p></div>	https://treatment.plazi.org/id/03C8879BC26B750BFCFDE9F7FDCEFCA3	Public Domain	No known copyright restrictions apply.
