A new tateid genus, Ngalidrobia n. gen., containing six new species, is described from groundwater sampled from wells in the Ngalia Basin in the Northern Territory, Australia. The new species differ in their shell morphology which ranges from near planispiral to conical. Of these species, two live in sympatry in one location, the remainder being allopatric. Of the named tateid genera, Ngalidrobia is, on the basis of molecular results using three partial sequences (cytochrome c oxidase subunit I, and 16S and 28S ribosomal RNA), most closely related to Trochidrobia from artesian springs in northern South Australia.

International audience; This study presents the first record of the previously monotypic family Bouchetispiridae (Neogastropoda: Conoidea) outside of New Caledonia and provides the taxonomic description of Bouchetispira ponderi n. sp. from deep waters off the coast of New South Wales, Australia. Molecular analysis based on cytochrome c oxidase subunit I (COI), 16S ribosomal RNA (16S rRNA) and 12S ribosomal RNA (12S rRNA) mitochondrial markers confirms its placement within the family, which is corroborated based on similarities of the shell and hypodermic radula to its sister taxon Bouchetispira vitrea. B. ponderi differs from the latter in having shouldered, distinctly less convex whorls and a thicker, more opaque shell, as well as in details of the radula. Furthermore, the molecular results presented herein support its recognition as a new species. B. ponderi bears notable similarities in several shell characters to Belomitra pacifica (Belomitridae), providing another example of convergence with regards to shell morphology in the Neogastropoda.

In the latest systematic revision of the camaenid land snail Kimberleytrachia from the Western Australian Kimberley region by Criscione and Kohler (2014), two species were confused. This error is corrected herein: The species described as K. leopardus Criscione & Kohler, 2014 is in fact identical with the earlier described species K. umbonis (Solem, 1979). Therefore, the name K. leopardus is a junior synonym of the latter. By contrast, material assigned to K. umbonis by Criscione and Kohler (2014) represented a yet unnamed species, which is here newly described as K. bachstenensis n. sp. Both species occur in the Prince Regent River National Park: K. umbonis occurs north of the Prince Regent River while K. bachstenensis n. sp. occurs south of it. http://www.zoobank.org/urn:lsid:zoobank.org:act:459E83CD-6C10-46AE-A73B-DDC5EB9F350A

The systematic classification of the Enidae of Timor is reviewed by means of comparative morphology and molecular phylogenetics using recently collected land snail samples from Timor-Leste (‘East Timor’). Features of the renal and genital anatomy as well as analyses of nuclear 28S rRNA sequences confirm the placement of the species in the Enidae. Generic combinations employed by earlier authors are discussed. The name Coccoderma Mollendorff, 1901 used for enids from the Indo-Australian Archipelago is pre-occupied by Coccoderma Zittel, 1887 and therefore not available. The assignment of species from Timor to Pseudonapaeus Westerlund, 1887, which is otherwise known from central Asia, is also rejected. Instead, the Enidae from Timor are here affiliated with Apoecus Kobelt, 1902, a name originally introduced for the Papuan species Buliminus colonus Mollendorff, 1895. While Apoecus samples from Timor-Leste form three distinct mitochondrial clades, only two groups can be reliably distinguished by their ...

A new species of Setobaudinia Iredale, 1933 (family Camaenidae Pilsbry, 1895) from the Kimberley region in Western Australia is described. Setobaudinia nicolasi n. sp. is endemic to Baudin Island, off the northwestern coast of Australia, where it occurs in sympatry with at least another three confamilial land snails. The new species is distinguished from other Setobaudinia species by a unique combination of features of its shell (low elevation and weak lip expansion) and male genitalia (inner penial wall sculpture of interlocking filaments).http://zoobank.org/urn:lsid:zoobank.org:pub:10FAB5A9-503A-4E3B-A67C-772D85658C91

The camaenid genus Damochlora Iredale, 1938 endemic to the Western Australian Kimberley is poorly defined by shell characters only. Two out of three previously recognised species have recently been removed from this genus and placed in Setobaudinia Iredale, 1933 rendering the type species D. millepunctata (Smith, 1894) the only member of this genus. Based on the study of ethanol-preserved material from the type locality, Baudin Island, we revise the taxonomy of Damochlora, which is maintained as a distinct and monotypic genus. The examination of material from Cassini Island previously considered to be conspecific with D. millepunctata on account of possessing a nearly identical shell revealed that these snails represent a distinct species, for which the taxon name cassiniensis Smith, 1894 is available. This species is characterised by a profoundly different reproductive anatomy and therefore recognised as a distinct genus, for which the new name Nannochlora is being introduced.http://zoobank.org/urn:lsid:...

Two new monotypic camaenid genera Cardiotrachia gen. nov. and Rachita gen. nov. are described for the two new species C. bastionensis n. sp. from the Bastion Ranges and R. carltonensis n. sp. from the Onslow Hills, respectively, in the East Kimberley, Western Australia. Cardiotrachia is characterized by distinct anatomical features, such as a small shell devoid of macroscopic sculpture with a peculiarly heart-shaped aperture and a coiled penis without epiphallus. Rachita is characterized by a shell flatter than that of any other camaenids of similar size from the East Kimberley, a lacking epiphallus and a complex penial wall sculpture. A mitochondrial DNA phylogeny corroborates the recognition of Cardiotrachia and Rachita as distinct genera with respect to other confamilial taxa from north-western Australia.http://zoobank.org/urn:lsid:zoobank.org:pub:60FA3A41-6A3B-4EBE-8B05-B7960B7EEEBF

The new, monotypic camaenid genus Arnhemtrachia is described for the new species Arnhemtrachia ramingining from Ramingining, Arnhem Land, Northern Territory, Australia with additional records from the Gove Peninsula in eastern Arnhem Land. This camaenid is characterised by a combination of distinct morphological features, such as a small, discoidal, keeled shell with regular axial ribs, open umbilicus and simple, rounded aperture as well as a reproductive system with a long epiphallus possessing a long flagellum and absence of a penial sheath, with a flap on the penial wall which transverses longitudinal pilasters, and a long, simple bursa copulatrix. Based on comparative morphology, Arnhemtrachia reveals affinities with Trozena morata Iredale, 1838 from NE Queensland.
