COMPARISON

Lindapterys domlamyi n. sp. is compared with L. sanderi Petuch, 1987 ( Fig. 10C, F, G View FIG ), 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 View FIG ). 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.
