Terrestrial snails on ABC islands

In the stream of end-of-year publications, Hovestadt & van Leeuwen (2017) just published an important overview of the land snails from Aruba, Bonaire and Curacao. The abstract reads “A review is given of the terrestrial malacofauna of Aruba, Bonaire, and Curaçao in the Dutch Caribbean. The most recent reviews of these islands were given in 1924 by Baker and in 1940 by Wagenaar Hummelinck. Wagenaar Hummelinck accepted fewer species and subspecies than Baker, without giving any arguments. Baker did give a detailed account making it possible to recognize his taxa in the eld. Genetic research by Harasewych in 2015 supported Baker’s views with regard to the genus Cerion. Figures are provided for most taxa so each can be identified. Helicina dysoni L. Pfeiffer, 1849, Leptinaria lamellata (Potiez & Michaud, 1835), and Polygyra cereolus (Megerle von Mühlfeldt, 1816) are reported here for the first time, Guppya molengraafi Baker, 1924 has been rediscovered”.

After an introduction dealing with geography, geology, climate and vegetation, the previous research on this group from the islands is discussed. The following systematical part gives data on the distribution followed by remarks, and an illustration of each species. This paper is a nice addition to earlier, recent papers on other islands in the Lesser Antilles.
