Chilean bulimulids

Just published in a not-so-common journal for a taxonomical paper: Juan Francisco Araya’s new paper on Bulimulidae from the Atacama region in Chile. This desert-like environment is only seemingly unfavorable for snails and is little researched so far.

The abstract reads: “The bulimulid genus Bostryx Troschel, 1847 is the most species-rich genus of land snails found in Chile, with the majority of its species found only in the northern part of the country, usually in arid coastal zones. This genus has been sparsely studied in Chile and there is little information on their distribution, diversity or ecology. Here, for the first time, a formal analysis of the diversity of bulimulids in the Region de Atacama, northern Chile, is reported. Of the seventeen species recorded for the area, most of themwere efectively found in the field collections and one record was based on literature. Five taxa are described as new: Bostryx ancavilorum sp. nov., Bostryx breurei sp. nov., Bostryx calderaensis sp. nov., Bostryx ireneae sp. nov. and Bostryx valdovinosi sp. nov., and the known geographic distribution of seven species is extended. Results reveal that the Region de Atacama is the richest region in terrestrial snails in Chile, after the Juan Fernandez Archipelago. All of the terrestrial molluscan species occurring in the area are endemic to Chile, most of them with restricted geographic distributions along the coastal zones, and none of them are currently protected by law. Further sampling in northern Chile will probably reveal more snail species to be discovered and described”. The study of Araya is thus a welcome additional to our knowledge of the Neotropical malacofauna.
