description: <i>Partecosta bozzettii</i> Malcolm &amp; Terryn new species (Figs 3K, 11E) <i>Type material:</i> Holotype: MNHN IM- 2009-10163, lv, 12.5 mm; Port d’Ehoala, SMadagascar, 25 ° 03 ' 43.9 ''S, 46 ° 57 ' 42.9 ''E, 3–4 m (ATIMO VATAE Stn TP29). Paratype 1: MNHN IM-2009- 10162, lv, 11.8 mm; type locality. <i>Zoobank registration:</i> urn:lsid:zoobank.org:act: 6E3E67B5-1B55- 4A99-8D39-6517DA4D065C <i>Diagnostic nucleotide positions:</i> Table 11. <i>Description</i>: Shell small. Protoconch paucispiral, 1 whorl, with broad nucleus. Holotype 9 teleoconch whorls; outline of whorls weakly convex. No subsutural band, or demarcation thereof, except for minor indentation of ribs; no visiblespiral sculpture. Axial sculpture of almost straight, thin ribs, 14 on penultimate whorl, stretching across whorl height; interspaces wider than ribs. Last whorl elongate, tapering towards base. Columella straight, aperture elongate. Shell colour off-white with darker-tinged spiral band adapically on whorls and below periphery; brownish blotches between the axial ribs abapically on whorls; inner columella dark brown or purplish. <i>Habitat</i>: In sand at 3– 4 m. <i>Distribution</i>: Known only from type locality. <i>Etymology</i>: The species honours Luigi Bozzetti (Italy), who has contributed tremendously to the knowledge of the molluscan fauna of SMadagascar. <i>Remarks:</i> The species resembles <i>P. trilineata</i> (Fig. 11F), but differs by its more globose and convex whorls and by having a single row of brown blotches instead of two. In addition, the protoconch of <i>P. trilineata</i> is differently shaped, having two whorls and a medium nucleus. The phylogenetic analysis of Modica <i>et al.</i> (2019) shows significant genetic distance between the two species. <i>Partecosta bozzettii</i> n. sp. shows some resemblance to <i>P. albofuscata</i>, but again differs by its more convex whorls, distinct axial ribbing and shell colour pattern. <i>Partecosta bozzettii</i> n. sp. is similar in general morphology and shell colour pattern to <i>Hastula daniae</i> (Fig. 2G) from West Africa, but the latter has a multispiral protoconch and more globose mature whorls.
