Lindapterys domlamyi Garrigues & Merle 2014, n. sp.
No full textLindapterys domlamyi n. sp. (Figs 10A, B; 12C) TYPE MATERIAL. — Guadeloupe, holotype (MNHN IM-2000-27732). TYPE LOCALITY. — East of Fajou Island, Guadeloupe, in 80 and 90 m deep. ETYMOLOGY. — Named in honour of Dominique Lamy. DESCRIPTION OF HOLOTYPE Protoconch unknown.Teleoconch oval, H 7.9 mm, up to 3.8 mm in width. Spire high of four rounded whorls. Last whorl of 76% of the total length of teleoconch. Apical angle of 53°. Spiral sculpture consisting in equally primary and secondary cords. On last whorl: convex part of the whorl, P1 to P5; siphonal canal, P6, ADP, MP and ABP. Axial sculpture: first whorls, eight to nine protovarices; from third to fourth whorl, appearance of two lateral varices giving to the shell a bivaricate shape, Between two varices five intervarical ribs. Aperture oval, with a adherent columellar lip. Anal canal open, tubular and formed by P1 cord spine. Outer lip flaring, slightly erected with denticles from D1 to D4. Siphonal canal open, of 26% of the total length of teleoconch and dorsally recurved. Shell white. Operculum and radula unknown. COMPARISON Lindapterys domlamyi n. sp. is compared with L. sanderi Petuch, 1987 (Fig. 10C, F, G), the single living species occurring in the western Atlantic area and to the type species of the genus, L. vokesae Petuch, 1987 (Fig. 10D, E). Lindapterys sanderi differs by the number of its protovarices on the first whorls (between 10 and 20), by a higher spire, by an outer lip widely flaring, by five denticles D1 to D5 (instead four in L. domlamyi n. sp.) and by a larger adult size (17.2 mm instead 7.9 mm in L. domlamyi n. sp.). Lindapterys vokesae has twelve to thirteen protovarices on the first whorls and the lateral varices appear earlier since the second whorl.Published as part of Garrigues, Bernard & Merle, Didier, 2014, Nine new species of Muricidae Rafinesque, 1815 (Mollusca, Gastropoda) from the French Antilles, pp. 841-864 in Zoosystema 36 (4) on page 862, DOI: 10.5252/z2014n4a7, http://zenodo.org/record/515967

Olssonia Sanders & Merle & Puillandre 2019, n. gen.
No full textGenus Olssonia n. gen. urn:lsid:zoobank.org:act: 9BB6F0C9-71ED-4F96-BAE8-3BA325B57714 TYPE SPECIES. — Bursa chira Olsson, 1930. DERIVATIO NOMINIS. — Dedicated to the American palaeontologist A. A. Olsson. SPECIES INCLUDED. — Olssonia chira (Olsson, 1930) n. comb., O. yasila (Olsson, 1930) n. comb. DISTRIBUTION. — Olssonia n. gen. is a genus restricted to the Eocene to early Miocene of Peru. DIAGNOSIS. — Shell biconic, dorsoventrally compressed, shortspired, with 7 primary cords on the convex part of the whorl, all but P1 evenly reduced in variceal and intervariceal intervals of each whorl (P1 hardly more expressed than other cords); posterior siphonal canal short; varices strictly aligned; prominent columellar callus. COMPARISONS. — Olssonia n. gen. resembles Marsupina but possesses a lesser number of primary cords on the convex part of the whorl (7 in Olssonia n. gen., 8 in Marsupina). It resembles Aspa but has a much more prominent columellar callus, it is much more granulose, and it has a more sharply defined shoulder and a wider spire angle. Olssonia n. gen. resemble Bufonaria (Fig. 3B), with the same straight anterior siphonal canal, but lacks a spine or blade on the posterior siphonal canal (Fig. 3B; white arrow). REMARKS The representatives of this genus are the oldest confirmed Bursidae; as such they can be used to calibrate the node Bursidae.Published as part of Sanders, Malcolm T., Merle, Didier & Puillandre, Nicolas, 2019, A review of fossil Bursidae and their use for phylogeny calibration, pp. 247-265 in Geodiversitas 41 (5) on page 254, DOI: 10.5252/geodiversitas2019v41a5, http://zenodo.org/record/369993
