The genus (Gastropoda, Truncatelloidea, Amnicolidae), with a new species from Bhutan.

The distribution of the five (Gastropoda, Truncatelloidea, Amnicolidae) species that are diagnosed by both morphological and molecular data is combined with several records of less completely diagnosed nominal species. The resulting distribution pattern is summarized in a map and is discussed herein. is described from Bhutan on the basis of shell morphology and two mitochondrial DNA barcoding markers.

Re-evaluation of von Frauenfeld, 1862 and Gittenberger, 1980, including the description of two new Iberian species using Computer Tomography (CT) (Eupulmonata, Ellobioidea, Carychiidae).

The present study aims to clarify the confused taxonomy of von Frauenfeld, 1862 and Gittenberger, 1980. Revision of Iberian micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian species, von Frauenfeld, 1862. In this paper, we clarify its taxonomic status by designating a lectotype from the original syntype series and by describing its internal and external shell morphology.

Fulfilling the taxonomic consequence after DNA Barcoding: sp. n. (Eupulmonata, Ellobioidea, Carychiidae) from Panama is described using computed tomographic (CT) imaging.

Five years ago, the Panamanian evolutionary lineage (EL) C12 was uncovered along with four other ELs in an integrative phylogenetic investigation of worldwide Carychiidae. Since EL C12 lacked shell material post-molecular analysis to serve as a museum voucher, it remained undescribed. Now, after recent collection efforts of C12 and the congener, Jochum & Weigand, 2017 at their original Panamanian sites, C12 is morphologically described and formally assigned the name, Jochum, In sync with recent taxonomic treatment of the genus, computed tomography (CT) is used in this work to differentiate shells of from geographically-proximal, Caribbean, North and Central American congeners.
