Revisão taxonômica das espécies do gênero Turbonilla Risso, 1826 (Gastropoda: Pyramidellidae) reportadas para o litoral brasileiro
The species ofthe genus Turbonilla Risso, 1826 previously recorded to the Brazilian coast are reviewed on a conchological basis after comparisons against their type-series. T abrupta Bush, 1899; T amoldai Jong & Coomans, 1988; T atypha Bush, 1899; T brasi/iensis Clessin, 1900; T coomansi Aartsen, 1994; T dispar Pilsbry, 1897; T fasciata ( d'Orbigny, 1840); T multicostata (C. B. Adams, 1850); T protracta Dall, 1892; T puncta (C. B. Adams, 1850); T rushii Bush, 1899; T turris (d'Orbigny, 1840); and T uruguayensis Pilsbry, 1897 are confirmed as valid species, with occurrence in the Brazilian coast. T puncturata Martens, in Clessin, 1900 and T haycocki Dall & Bartsch, 1911 are placed in synonymy with T rushii and T puncta, respectively. The lost of the type material of T portoricensis and T iheringi, both Clessin, 1900, combined to their poor original descriptions and illustrations, do not allow the recognition of the concept of these taxa, making them non-identified and known by their original descriptions only. The records of T nivea (Stimpson, 1851) and T interrupta (Totten, 1835) were based on misidentifications and these species do not belong to the Brazilian malacofauna. "Turbonilla" dubia (d'Orbigny, 1840) does not belong to the family Pyramidellidae, being reallocated in the genera Finella A. Adams, 1869, family Diastomatidae. The lectotype of T americana (d'Orbigny, 1840) does not fit the original concept of this taxon, removing it from the family Pyramidellidae and from the Brazilian malacofauna, and must be replaced by one of the remainder syntypes after ruling by the International Commission on Zoological Nomenclature.
