Stormy weather with lots of rain may awake lots of snails from dormancy. These pictures were taken in northwestern Florida, Santa Rosa County, Bagdad. Harry Lee recognized them as Rabdotus dealbatus (Say, 1821) and this is likely the first record for Florida of this species.
Under this (beginning of the) title Piz?? & Cazzaniga (2012) published their fifth joint paper on Argentinian Plagiodontes species.

A new paper was just published (Breure & Whisson, 2012) on types of Bothriembryon snails from Australia. Not Neotropical, but from the Gondwanan part of the Orthalicoidea.
Some months ago, a big paper on the subject mentioned above was published by Miquel & Aguirre (2011). The abstract of the publication reads as follows:
Does counting count as science? Yes, it does in taxonomy.
Just published, a paper on land snails of Malpelo Islands, Colombia (Hausdorf et al., 2012).
The fauna of the volcanic island Malpelo located west of Colombia’s Pacific coast includes only two species of land snails. One is a new endemic species of the subulinid genus Ischnocion, with which Rectobelus, Microbeliscus and Nannobeliscus are provisionally synonymized. Ischnocion conica new species differs from other species of the genus in the conical shell with radial palatal folds in juvenile stages. The other land snail species from Malpelo Island represents a new endemic thysanophorid genus. This genus, Malpelina (type species: Malpelina labiata new species), differs from other taxa of the Thysanophoridae in the yellowish-brown, depressed-globular shell with a distinctly thickened peristome, a broad glandular genital atrium, the lack of a vagina, a long penis, a long and exposed talon and the lack of entocones from all radular teeth. Malpelina is more closely related to Central American taxa than to thysanophorids from the Colombian mainland. Thus, it is more likely that Malpelo Island has been colonized by Malpelina from the north in accordance with palaeotectonic reconstructions. It is less clear whether Ischnocion reached Malpelo Island from Central or from South America, because the genus is distributed in both regions. Both species are patchily distributed on Malpelo and live under rocks in high densities. Their abundances increase towards higher altitudes. There is some segregation concerning the resting sites. Ischnocion conica rests on the soil or partially buried, while M. labiata almost always hangs from the underside of rocks.
