Two papers on CCP snails

Two papers were published, one very recently and one today, related to the material collected by the ‘Comisión Científica del Pacífico’ (CCP). This material was collected during an expedition that lasted from late 1862 to  early 1866 through several Neotropical counties. The material has been deposited in the Madrid museum and was originally studied by Hidalgo (terrestrial molluscs, marine gastropods) and Martínez (marine bivalves).

The terrestrial material has been restudied during a SYNTHESYS project last year, and has resulted in two papers. One dealing with the CCP material and the history of the expedition (Breure & Araujo, 2017), and one dealing with the publication date of Hidalgo’s main paper on the CCP material and related correspondence from him with Crosse in Paris (Breure & Backhuys, 2017).

The link to the first paper is here.

Update:
Due to an unfortunate coincidence at the proof stage (we unexpectedly received only one proof), the following corrections were not made in the published version:
Fig. 3 in the text (page 4) correspond to Fig. 2B
Fig. 4 in the text (page 5) correspond to Fig. 3A
Fig. 5 in the text (page 6) correspond to Fig. 3B
Fig. 6 in the text (page 6) correspond to Fig. 4A
Fig. 7 in the text (page 7) correspond to Fig. 4B
Fig. 8 in the text (page 9) correspond to Fig. 5A
Fig. 9 in the text (page 10) correspond to Fig. 5B
Fig. 10 in the text (page 12) correspond to Fig. 6A
Fig. 11 in the text (page 12) correspond to Fig. 6B
Then, after Fig. 11 in the text, appear Figs. 7A-7B (page 17) that actually correspond to the Figures 7A and 7B; later (page 17) appears Fig. 8G-8H that correspond to Fig. 8.
Finally, Fig. 27H does not depict Bostryx rouaulti as the wrong shell was photographed.

Snails from central Chile

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”.

New paper

In the latest issue of the Journal of Conchology a paper appeared by Araya et al. about the occurrence of Bostryx hennahi (J.E. Gray, 1828) in northern most Chile and southernmost Peru.

This species appears confined to fog oasis in the extreme arid deserts in the region, and is thus an example of a harnessed species to harsh conditions.

New species from Juan Fernandez Archipelago

Miquel & Araya (2015) recently published on new shells from the Juan Fernández Archipelago off the coast of Chile. This is the first addition since nearly a century ago. One species is new described, Neoparyphantoplsis crusoeana gen.n., sp.n.; one replacement name is introduced (Tornatellina juanfernandeziana), and five species are re-described.

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.
