Study of Mite Species

A sample of land snails was recently collected in a fragment of Atlantic rainforest, in the vicinities of the city of Nanuque (north of Minas Gerais state, Brazil), totaling 15 species. The following new species are herein described: Leiostracus carnavalescus n. sp. and Rhinus botocudus n. sp. (Bulimulidae), and Obeliscus boitata n. sp. (Subulinidae), the first two accompanied by anatomical descriptions. Moreover, the geographical ranges of some species are extended to Minas Gerais: Auris bilabiata, Bahiensis cf. bahiensis, Cyclopomops moricandi, Dysopeas muibum, Helicina boettgeri, Helicina variabilis, Prohappia besckei, and Rectartemon piquetensis. The discovery of new species in such a small forest fragment is a clear reminder of how little the Brazilian terrestrial snail fauna is known. It also points to the fact that these few remaining forest fragments may house many new and possibly endemic species and should, therefore, be properly preserved.
