Taxonomy of fossils and recent species sometimes intertwines as demonstrated by a new publication of Kadolsky.
A nice update for the correct names of the Hispaniolan malacofauna.

The group ‘Speurneuzen’ makes nearly every week a hike on the Island of Curaçao, usually to look for cultural-historical objects, but always to enjoy nature. This week they followed a new trail made by ‘Uniek Curaçao’ from Fort Kloof to Ascuncion. From their photo report I show a small batch of Drymaeus elongatus on a Wayaca tree.
The picture was made by Fred Chumaceiro.
This is a very artistic picture of a snail ‘meeting’ near Polo, Dominican Republic, with Coloniconcha prima Pilsbry, 1933 as the star player, who is clearly in a hurry. According to Ignacio Agudo the other snail is Cysticopsis sp. He gave as photographer Carlos de Soto Molinari.
The third post on Watters’ 2016 papers concerns his review of the Paracondria (Chondropomorus) complex. “Nineteen species are recognized including eight new species: Parachondria anatolensis n. sp., Parachondria arcisensis n. sp., Parachondria daedalus n. sp., Para- chondria heatheraikenae n. sp., Parachondria isabellinus n. sp., Parachondria muchai n. sp., Parachondria silvaticus n. sp., and Parachondria stigmosus n. sp. Distributional and habitat notes are given for additional taxa. Chondropoma marinum “Weinland” Reeve, 1863, is regarded as a nomen dubium. Chondropoma (Chondropomorus) moroni Bartsch, 1946, is reidentified as Crossepoma emilianum (Weinland, 1862). Chondropoma simplex Pfeiffer, 1852, regarded by Bartsch (1946) as a Chondropomorus, is considered a Chondropoma”.

Thomas Watters has published last year a series of papers on Antillean Annulariidae which have not been mentioned here. Today I start with a paper on the Dominican Republic; the abstract reads “A new genus and species of Annulariidae are described from the Dominican Republic: Tessaripoma n. gen. and Tessaripoma arenarium n. sp. The genus also contains T. hooksi (Watters & Duffy, 2010) and T. alyshae (Watters & Duffy, 2010). The genus is endemic to the eastern end of the Hoya de Enriquillo between the Tiburon/Barahona Peninsula and the remainder of Hispaniola”.

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).

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.
