In den WarenkorbA new genus and a new species of Eulimidae are described based on the shell morphology and on the host-parasite relationship of the type species. Eulimacrostoma microsculpturata Souza & Pimenta gen. nov. and sp. nov. parasitizes a starfish of the genus Luidia and has an elongated, conical, straight, or slightly curved shell, a p…rotoconch with a brownish spiral band and convex whorls, a peculiar large and broad aperture with a strongly protruding outer lip, and microsculpture of axial lines on the teleoconch. Four other species are included in the genus, all from the western Atlantic: Eulimacrostoma chascanon (Watson, 1883), comb. nov., Eulimacrostoma fusus (Dall, 1889), comb. nov., Eulimacrostoma lutescens (Simone, 2002), comb. nov., and Eulimacrostoma patula (Dall & Simpson, 1901), comb. nov. Newly available material of Eulimacrostoma patula expands the known geographic distribution of this species in the Caribbean to the north coast of Brazil. Eulimacrostoma chascanon and Eulimacrostoma fusus and Eulimacrostoma lutescens are known only by the type series which was re-examined. A redescription is provided for Eulimacrostoma chascanon and Eulimacrostoma fusus. Species within Eulimacrostoma differ mainly by teleoconch sculpture, the presence or absence of an umbilical fissure, and shell dimensions. Lectotypes are designated for Eulimacrostoma chascanon, Eulimacrostoma fusus, and Eulimacrostoma patula. pp. 403-415, 5 figs, 4.

In den WarenkorbThe species of the genus Turbonilla described from the Brazilian coast are redescribed, based partly on SEM studies. Turbonilla fasciata (d'Orbigny, 1840), T. turris (d'Orbigny, 1840), and T. brasiliensis Clessin, 1902, are confirmed as valid species. T. puncturata Clessin, 1900, is placed in the synonymy of T. rushii Bush, 1899…. Type specimens of T. iheringi Clessin, 1900, and T. portoricensis Clessin, 1900, were not located, and these nominal species are considered unrecognizable. The lectotype of T. americana (d'Orbigny, 1840) does not fit the original concept of that taxon, it does not even belong to the Pyramidellidae; it should be replaced by the remaining syntype after a ruling by the International Commission on Zoological Nomenclature. T. dubia (d'Orbigny, 1840) is classified in the genus Finella A. Adams, 1869. T. macaensis spec. nov., which has been determined elswhere as T. fasciata, is described from the northern coast of the state of Rio de Janeiro; it occurs from the Brazilian state of Espírito Santo to the coast of Argentina. 20 pp., 41 figs, gr. 8.
