Resumo(s)
O planorbídeo Biomphalaria pfeifferi de Moçambique (África Oriental Portuguesa) é indistinguível morfològicamente de Taphius ( =Australorbis) centimetralis do Brasil. As duas formas são capazes de cruzar livremente, produzindo híbridos viáveis e férteis, cujos descendentes podem ser mantidos através de gerações sucessivas no laboratório. Estes factos indicam a identidade das duas formas. Se esta conclusão for confirmada pelo estudo do material topotípico, o nome específico centimetralis Lutz, 1918 tomar-se-á sinónimo de pfeifferi Krauss, 1848, o nome genérico Biomphalaria Preston, 1910 tornar-se-á sinónimo de Taphius Adams e Adams, 1858, e a denominação correcta da espécie será Taphius pfeifferi (Krauss, 1848).
The planorbid snail Biomphalaria pfeifferi from Mozambique (Portuguese East Africa) is morphologically indistinguishable from Taphius ( = Australorbis) centimetralis from Brazil. The two forms are able to cross freely, producing viable and fertile hybrids, the offspring of which may be maintained in the laboratory. Those facts indicate the identity of both forms. It this conclusion is confirmed by the study of topotypic material, the specific name centimetralis Lutz, 1918 will become a synonym of pfeifferi Krauss, 1848, the generic name Biomphalaria Preston, 1910 will become a synonym of Taphius Adams and Adams, 1858, and the correct denomination of the species will be Taphius pfeifferi (Krauss, 1848).
