Plagiodontes

New taxa (18): Plagiodontes

Plagiodontes is a genus belonging to the family Orthalicidae, subfamily Odontostomidae. The seven species currently recognized occur in three disjunct area in Argentina and Uruguay. Recently Pizá & Cazzaniga revised part of the genus and described a new species from Argentina, Prov. Catamarca, Cuesta de la Chilca: P. weyrauchi sp.n. (holotype MACN-In 37465).

Their paper describes very nice and in detail the anatomy of the taxon and compares it with known data of other small
Plagiodontes species. Since the shells are very similar, a morphometric analysis is provided, showing the differences.

I’m sure this paper will act as a cornerstone for future publications on this group and it contains very useful anatomical data. Proficiat to the authors!

Photo of the day (22): Plagiodontes

This one happened to creep on my way as a blogger. More details later, but this is a (new) species of Plagiodontes from western Argentina. These beautiful creature had his bad luck day, because after being photographed he was put in boiling water. Ough! Never do that to snails. Not only it destroys DNA, you won’t get the first prize from the Animal Rights Movement either... Besides, it’s too old fashioned :-)
All joking aside, this photo shows how curious snails are. See it’s little eyes inspecting the world. Little could it know that the malacologist would inspect and dissect it. Only a small sacrifice for the advancement of science.
