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.
