Redescrição morfológica e distribuição geográfica de subulinídeos no Brasil e inferências sobre o status de conservação de espécies dos gêneros Obeliscus e Synapterpes (Gastropoda: Subulinidae)

Abstract

In the middle of the XVII and XVIII centuries, many expeditions were carried out, where foreign naturalists described and cataloged the diversity, making them widely studied and deposited in biological collections all over the world, for the recognition of the fauna, flora and their history. The study of these collections is necessary, as they preserve materials of historical, taxonomic, educational and conservationist importance of biodiversity, these being the main objectives of a biological collection. In the 21st century, we live under the globalization of information and data and, much of the data generated in the past, integrates online databases that aim to gather dispersed studies and biological collections and thus becomes the only space for allocating information. This facilitates the updating and modification of information about diversity and facilitates access by several people from different backgrounds. Whith this, there is a disparity between the speed of incorporation of specimes in the collections and the time required to carry out taxonomic studies and, especially, to describe new species. Thus generating a taxonomic impediment to the real knowledge of the Family Thus, the objective of the work was to carry out a survey and geographic distribution of exotic and native species of the Subulinidae family occurring in Brazil, from access to databases and scientific collections. To prepare the species distribution maps, the data were georeferenced with the help of the Google Earth Pro software and made using the DIVA-GIS 7.5.0 software. As well as the redescription of internal anatomy and its morphology. The present study resulted in a total of 825 records of exotic species, with 194 records of the species Allopeas gracile, in 15 states and 30 municipalities, Rumina decollata, with 55 records for six states and 16 municipalities and for species Subulina octona accounted for 576 records in 22 states and 116 municipalities. The species A. gracile and S. octona have a wide distribution in Brazil, being observed in all regions, whereas the species R decollata was found only in the Northeast, Southeast and South regions and for native species it was registered in 150 for the genera of Obeliscus and Synapterpes with distribution in the Northeast, Southeast and Midwest regions. The study of exotic and native species of the Subulinidae family in the malacological collections and biodiversity database provided the observation of new occurrence records for species, as well as better knowledge about their geographic distribution in Brazil and the creation of future conservationist actions for native species and management of exotic species.
