New literature

Recently several new papers have been published by colleagues, of which I here mention two related to Neotropical land snails.

The first one is a paper by Barrientos (2010) on the terrestrial malacofauna of Costa Rica. It is a review, summarizing the different aspects of our current knowledge. Up till now, 135 species are known and despite this being one of the more well-known countries, it is expected that the total number of species could rise up to 400. The percentage of endemism is 30%. There are two main reasons: a) the biology, genetics and distribution are unknown for the majority of the taxa, and ‘cryptic’ species might be unveiled once our knowledge progresses; b) the highland areas are relatively under-sampled, and new taxa of micromolluscs (especially Euconulidae) are expected here.

The second paper is summarizing our knowledge on snail and slug eating snails in Brazil. Snakes of the Dipsadidae have been regularly observed to feed on slugs (Veronicellidae spp.) and occasionaly on snails (Drymaeus interpunctus, Brabybaena similaris). This is documented by photographs, of which several not published before.
