New species of Thaumastus from Lagoa Santa region, Minas Gerais State, Brazil (Mollusca, Gastropoda, Pulmonata, Bulimuloidea)

Abstract

ABSTRACT.A new species of Thaumastus (Thaumastus) Martens, 1860, from Minas Gerais State, Brazil, is described and illustrated, based on the morphology of the shell, jaw, radula and soft parts.

Two new species of Thaumastus (Gastropoda: Pulmonata: Orthalicidae: Bulimulinae) from the state of Minas Gerais, Brazil

“…The Brazilian species of Thaumastus were characterized by JURBERG et al (1979JURBERG et al ( , 1988, BARROS et al (1991), , , PENA et al (1996PENA et al ( , 2005. The intention of our research on species of Thaumastus is to re-characterize its subgenera as well as to provide a basis for a future phylogenetic analysis of the genus.…”

Range extension of Thaumastus caetensis Pena, Salgado and Coelho, 2011 (Gastropoda: Orthalicidae: Bulimulinae) in the highlands of Minas Gerais, southeastern Brazil

“…In this subfamily, Thaumastus Albers, 1860 is a South American genus of land snails represented by six subgenera: Thaumastus s.s., T. (Scholvienia), T. (Kara), T. (Quechua) and T. (Atahualpa) described by Strebel (1910), and T. (Thaumastiella) described by Weyrauch (1956). The only subgenus recorded in Brazil is Thaumastus (Breure 1979), with 31 species, which has been studied by several authors in the last years (Jurberg et al 1979(Jurberg et al , 1988Barros et al 1991;Pena et al 1996Pena et al , 2005Pena et al , 2011. In the state of Minas Gerais, southeastern Brazil, there are records for four species that are associated to limestone outcrops or mountain tops (Pena et al 2005(Pena et al , 2011.…”
