Laurent Charles published the preliminary results of his field work on the island of Guadeloupe, Lesser Antilles recently. The text is in French, with a brief summary in English as follows “Guadeloupe malacofauna has been subject to very few studies. After a short reminder of the 19th and 20th centuries studies, I present the first results of the field work undertaken in 2014 and 2015, that lead to recognize at least 73 taxa in the archipelago. I present the main facts on the specific diversity encountered in Guadeloupe and assess endemic, rediscovered and recently introduced species”.
In the paper is a list of species endemic to Guadeloupe (espèces endémique) or to the Lesser Antilles (espèces endémiques regionales).

Via the Conch-L site the news reached me that on the 27th December Fred Gilbert Thompson died in his home in Ocala, Florida. He was a renowned specialist on Neotropical snails, collected for many years in Central America but visited also several countries in South America. He was always willing to help and several times put his field notes at my disposal when preparing manuscripts partly based on his material. His recent checklist on Central American land and freshwater molluscs will be a valuable source for everybody working with material from that area.
In The Shell-O-Gram of the Jacksonville Shell Club the following obituary appeared:
The abstract of the new paper by Araya (2016) reads: “Among the terrestrial invertebrates, the molluscan species of central and northern Chile have been scarcely studied and here, for the first time, a record of the diversity of land snail species of Los Molles (32◦14′ S, 71◦31′ W), in the Valparaíso region, central Chile is reported. Four species were found: Chiliborus rosaceus (King & Broderip, 1831); Lilloiconcha lopezi Araya & Aliaga, 2015; Plectostylus chilensis (Lesson, 1830), and Plectostylus reflexus (Pfeiffer, 1842); all of them are ground dwelling snails, endemic, occurring in small geographical ranges or in fragmented populations along northern and central Chile; L. lopezi is an endemic species to Los Molles. The geographic distribution records of P. chilensis and P. reflexus are also extended and illustrations of the species and distribution records are presented. The areas around Los Molles harbor a comparatively high diversity of plants and invertebrates, and they should be considered in future conservation efforts”.

Just published: an overview of new species and additional data obtained during 2006-2016, as an addition to the book of Simone on Brazilian non-marine molluscs.
“A list of Brazilian terrestrial and freshwater gastropod species and genera described from 2006 to 2016 is presented, updating the previous catalogue of simone (2006). Colored photographs of type specimens, as well as information on type material, distribution and taxonomy are also provided. The list encompasses 42 recently described species, largely pulmonates, including 39 terrestrial, and three freshwater taxa. New genera are: Syneancylus Gutiérrez Gregoric 2014; Cli- nispira Simone & Casati 2013; Habeas Simone 2013; Kora Simone 2012; Olympus Simone 2010; Spiripockia Simone 2012 and Vegrandinia Salvador, Cunha & Simone 2013. The appendix lists native species whose known geographical ranges in Brazil have been extended considerably during this period, as well as those previously unrecognized in Brazil”.
During these years 42 species were newly described, which are re-figured here. Eight species are listed in the appendix as new to the Brazilian malacofauna.

Each malacologist is part of a network. In this case a known network which is actively maintained (friends and colleagues), and a network – probably more fluent – which is unknown to me: you who read this is among them…
Since I have become more and more interested in the network of malacologists in the past and how this was shaped, I have chosen this topic as theme for my yearly Season’s Greetings card.
Although several faces and handwritings might be familiar to you (if not see here and here for more), my guess is that many of you have little clue. But if you are familiar with some of the history of malacology, you might be able to answer the question “Who is the man whose son can be seen here twice?”… And who is that lady anyway? See here for a little explanation. You might be surprised…
In the most recent number of Spirula, one of the journals of the Netherlands Malacological Society, Neckheim & Hovestadt have published a paper in which they discuss our current knowledge on the non-marine molluscs from the Caribbean island Sint Maarten – Saint Martin (half Dutch / half French), partly based on their own surveys between 1991-2015. Since this paper entirely is in Dutch, I will provide here an extensive summary.
Despite being well explored there is remarkable few data documented in the malacological literature about this island. Neckheim & Hovestadt discuss the published reports (citing my Bulimulus paper twice with a wrong year 🙂 before dealing with some interesting localities. In the systematic part they discuss each species, the distribution on the island and – where relavant – nearby islands, and give an illustration of each species. In total they list 32 species of land shells, with an additional list of two species that potentially might occur. For freshwater snails they discuss their findings of four species, but remark that more species have been reported but have not been found during the surveys by the authors.

In the most recent number of Basteria Hovestadt published a short paper on the Peninsula de Paraguaná in Venezuela, describing a new Annulariid species: Tudora paraguanensis. The new species is the first record of Tudora from the South American mainland, and although the collected specimens are regarded as ‘subfossil’, it cannot be excluded that the finding of living specimens is possible.
