The Journal of Conchology has recently published some papers relevant to Neotropical land snails. Today, I mention the paper by Porto et al. (2017) about Oxychona.
The abstract reads “A new species of Oxychona was found during excursions to the Michelin Ecological Reserve (13°S), Southern Bahia State (Northeastern Brazil), which comprises an Atlantic Rainforest Conservation Unit. Living snails and empty shells were collected from ground litter accumulations and kept in an artificial environment supplied with local water and sediment, feeding on leaves of almond tree (Terminalia catappa L.). The new species is described and compared with others from adjacent areas of Brazil between 13oS and 15oS including O. bifasciata, O. currani and O. maculata. Oxychona n. sp. is likely to be endemic to Bahia State, thus supporting the biodiversity and rates of endemism of pulmonate molluscs to the Tropical Atlantic Rainforest in Southern America”.
This is a very nice paper as the authors have taken the effort to include a key to Oxychona species. So, although this paper only described a single new species, it still has broader application. The authors also give anatomical and ecological details.
The main author, Beth Neves, was kind enough to send me a short film of a living specimen of the new species, which I’m happy to share here.
