New records of land-snail species from caves of Mato Grosso state, Midwest Brazil (Gastropoda, Neritimorpha and Stylommatophora)

Abstract

Recent collection efforts in caves of Mato Grosso state, Brazilian Midwest, have brought to light specimens of four Neritimorpha and Stylommatophora land-snail species previously unrecorded from that state: Helicina fulva d’Orbigny, 1835 (Family Helicinidae), Streptartemon abunaensis (F. Baker, 1914) and Streptartemon decipiens (Crosse, 1865) (family Streptaxidae), and Systrophia alcidiana Ancey, 1892 (family Scolodontidae). These records are not only the first from that state, but also represent large extensions to those species’ known distributions, as well as their first records from a cave habitat.
