Many aspects of the evolution and biogeography of land snails remain unexplored for all but
the most well studied families in select few areas of the world. The evolutionary history of …

Pacific island land snails exhibit exceptionally high species diversity, morphological
diversity, and endemism. Species within superfamily Punctoidea, which contains the …

The amber fossil record of land snails is poorly studied, with few described species relative
to other invertebrate groups (eg, insects and chelicerates). Recently discovered land snail …

The land snail superfamily Punctoidea traditionally included seven families distributed
worldwide, to which a possible origin in North America had been assigned. Its classification …

Other than hard bones and shells, it is rare for soft tissues to fossilize, but occasionally they
are well-preserved in amber. Here, we focus on both modern and fossilized species of the …

Land snails in mid-Cretaceous Burmese amber have aroused interest from palaeontologists
in recent years. Here we describe three newly discovered species and a new genus …

Three species of camaenid land snails occur on Barrow Island: Quistrachia barrowensis and
two previously unassigned species of Rhagada. Based on morphological re-evaluation and …

Pacific island land snails are among the most imperiled animals on Earth, which elevates
the practical conservation importance of their systematics and biogeography. The …

Background The biodiversity and distributions of terrestrial snails at local and regional
scales are influenced by their low vagility and microhabitat specificity. The accessibility of …

Analyses of molecular phylogeny have revealed that phenotypically identified taxa do not
reflect phylogenetic relationships. Such taxa often are not evolutionary significant and are …
