Cecilioides in Argentina

Diaz et al. recently published a new record of an introduced species for Argentina. “Cecilioides acicula (Müller, 1774), family Ferussaciidae, is native to the Palaearctic region but has been dispersed around the word by human activity. Here, we report the presence of this introduced species in La Plata city, Buenos Aires province, Argentina. This snail is largely subterranean and frequently is found in old graves in association with skeletal remains. Our samples were collected from sediments from the Municipal Cemetery of La Plata, Buenos Aires province, Argentina”.

Predation by land planarians

Land planarians are increasingly been reported as predators of land snails, and several reports have been summarised by Cseh et al. (2017), as well as presenting new data.

“The food preference of Obama anthropophila Amaral, Leal-Zanchet & Carbayo, 2015, a species that seems to be spreading across Brazil’s human-modified environments, was investigated. Extensive experiments led to the conclusion that the generalized diet of this species may have facilitated its dispersal. The analysis of 132 feeding records of 44 geoplaninid species revealed a tendency for closely related species to feed on individuals from similar taxonomic groups, suggesting that in this group behavioral evolution is more conserved than phylogenetic diversification”.

The paper supplies a table with the known prey animals of land planarians.

An overlooked designation

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.

Bourguignat letters

A new paper was just published which sheds some light on the controversy between Bourguignat and Crosse during the last half of the 19th century. This is a publication of the project on the history of European malacology.

Petit de la Saussaye

Just published: a study about Petit de la Saussaye, the founder of the Journal de conchyliologie in 1850. The paper gives a short biography, his bibliography, a list of his described taxa and some of his correspondence that was found in an archive.

New Scutalus from Chile

Freshly published: a paper with the description of a new species from northern Chile. The species, of which only shells were collected, is tentatively assigned to the genus Scutalus. This genus is hitherto not recognised in Chile, but occurs more northern in the coastal area of Peru.

The abstract reads “A new species of Scutalus Albers, 1850 (Gastropoda: Bulimulidae), Scutalus chango sp. n., is described from a coastal area of northern Chile. Empty shells of this new species were found buried in sand and under boulders and rocks in the foothills of the Chilean Coastal Range at Paposo, Región de Antofagasta. This new species is distinguished from all other Chilean terrestrial snails by its slender shell with a flared and reflected aperture, and by the presence of a columellar fold. This is the first record of Scutalus in Chile, and the southernmost record for this endemic South American bulimulid genus. The presence of this species in Paposo highlights the need for further research and for conservation guidelines in coastal areas of northern Chile, which have comparatively high levels of biodiversity and endemism”.

New papers

Incidentally two new papers were published this weekend, both on historical malacology. One of on Henri Martel (1846-1927). “The “correspondence conchyliologique adressée à Henri Martel” is preserved in the Dautzenberg archives. This resource gives a good picture of the contact network of this amateur, who was mainly active after his retirement from military service. Summaries are given of the letters which were sent to Martel by Bavay, Dautzenberg, and Pallary”.

The second paper deals with the contributions of Baudon: “Biographical data is presented about Auguste Adolphe Baudon (1821-1905), together with a bibliography of his malacological works. His new taxa, both Recent and fossil, are listed, as well as eponyms dedicated to him. His network of scientific contacts has been reconstructed from his papers and his correspondence archive, for which an overview is presented listing his correspondents, the time period and the number of letters”.
