ABSTRACT Aplacophorans are vermiform marine molluscs found in benthic habitats worldwide. However, there is an extreme lack of knowledge about their true diversity. There are around 440 described species, but the true number is estimated to be at least tenfold higher. Identifying most solenogaster aplacophorans to the species, genus and sometimes even family level requires histology so that internal anatomical structures, such as the radula, foregut glands, and reproductive organs can be characterised. The aplacophoran faunas of many regions have barely been studied or have not been studied at all. An example is the waters surrounding New Zealand where only three species have been described to date. To advance the understanding of the biodiversity of Aplacophora, we describe three new species of solenogaster aplacophorans from New Zealand, all of which belong to the family Proneomeniidae Simroth, 1893: Dorymenia tanifa n. sp., Dorymenia ancora n. sp. and Dorymenia lucida n. sp. New data on Dorymenia quincarinata (Ponder, 1970) are also included and a comparison of all Dorymenia species is described in detail. In addition, DNA barcodes were obtained from D. lucida n. sp. and D. quincarinata, which will be useful for future specimen identification by non-experts and future studies on aplacophoran evolution.

ABSTRACT Kerkia is a snail genus inhabiting mainly subterranean waters. Live specimens of Kerkia were collected in the West Balkans. Mitochondrial cytochrome c oxidase subunit I and nuclear histone H3 were sequenced. Populations of Kerkia molecularly represented 10 mOTUs, each deserving a species rank. Apart from known species, five new species are described. The interspecies differences in shell morphology were slight and thus morphology did not reflect the evident molecular differences. All available information about the penes and female reproductive organs are summarised and their limited usefulness in species-level taxonomy is discussed. Kerkia seems to represent another example of morphostatic evolution, a result of non-adaptive radiation marked by the rapid proliferation of sibling species, whose ecology most probably remains the same. In Kerkia, intrapopulation genetic diversity does not (or almost does not) exist, and the same is true for intraspecies variation. At the same time, there is a high level of molecular difference between the species. Despite potential means for range expansion of the stygobiont fauna provided by interstitial habitats, which reduce the levels of endemism in some stygobiont gastropod species, the species of stygobiont Kerkia are restricted to small geographic areas.

ABSTRACT For over 50 years Winston Ponder has been at the forefront of molluscan research. Young Winston collected land snails in the environs of Lower Hutt, New Zealand and marine species at Waikanae Beach northwest of Wellington. He attended Victoria University in Wellington in 1959 but moved to Auckland University in 1960 to study under Professor John E. Morton, with whom he completed his B.Sc. in 1963 (Galeommatoidea), his M.Sc. with 1st Class Honours in 1965 (Rissoidae), and his Ph.D. in 1968 (Neogastropoda). Winston was appointed Curator of Marine Invertebrates at the Dominion Museum in 1967. However, he soon moved to Australia after accepting the position of Curator of Molluscs at the Australian Museum in 1968. He would spend the next 37 years there. Winston has published in almost 50 different scientific journals and numerous edited books and volumes. He has collaborated with almost 100 different co-authors from around the world and has addressed multiple taxa and questions across the phylum. He has been a strong advocate for Australasian malacology. His advocacy has also included a robust outreach to students. However, his advancement of Australasian malacology was not done to the exclusion of the global role and needs of the discipline.

ABSTRACT Gastropoda is probably the best-known taxon which uses acid glands as an antifouling strategy and as defence against putative predators. Here, defensive acid-secreting cell types in two taxa of Caeonogastropoda, Cypraeidae and Ovulidae, were investigated. This study confirms the presence of acid epithelial glands in several members of the Cypraeidae, with the glands of the Cypraeidae species Naria nebrites and Mauritia mauritiana being newly described here. We also present results for the first time on a member of the family Ovulidae, Simnia spelta. All investigated species exhibited an outer epidermis with glandular acid cells of columnar shape with large clear, colourless vacuoles, thus resembling the previously described species of these taxa. None of the investigated cypraeid and ovulid species studied here exhibited subepidermal acid glands in the mantle, which are typical for the Velutinoidea. The phylogenetic value of these findings is discussed in relation to a recently published phylogeny on Caenogastropoda comprising all families of Cypraeoidea and Velutinoidea.

ABSTRACT The aim of this work is to investigate the effects of environmental stressors on male reproductive biomarkers in sentinel species of bivalves inhabiting Annaba estuaries, considered to be reservoirs receiving industrial, agricultural, and domestic discharges. Male Mytilus galloprovincialis were collected in four seasons from a non-polluted site (S1) and two other locations receiving untreated sewage (S2) and a mixture of contaminants (S3). Testicular sperm concentration, motility, velocity, the amplitude of lateral head displacement (ALH), the beat cross frequency (BCF), spermatozoan DNA fragmentation, and histological profiles were evaluated. Individuals from S2 and S3 have diminished sperm concentration, motility, velocity, ALH and BCF, along with a significantly increased spermatozoan DNA fragmentation that was much higher in S3. Testicular tissues demonstrated histo-pathological alterations in mussels subjected to anthropogenic activities during the four seasons. In conclusion, reproductive biomarkers of male mussels were both spatially and temporally variable, which is probably correlated to pollution types and the changing seasonal stressors.

ABSTRACT Inle Lake in central Myanmar is one of the hotspots of freshwater biodiversity in Southeast Asia. A small malacological collection from the lake made by Thomas Nelson Annandale and discovered at the Kyoto University Museum, Japan was examined here. In the collection comprised of thirty specimens, nine species in seven families were identified. The collection also included four species and one subspecies which were newly described by Annandale. Two subspecies, Hydrobioides nassa lacustris Annandale, 1918 and H. n. rivulicola Annandale, 1918, were identified in a single lot. The correspondence of the shell morphology of Lamellidens ferrugineus (Annandale, 1918) between the present study and the original description indicates that the specimen is a paratype of the species. The rediscovered collection provides us with insights into the species definition of Annandale and the molluscan diversity of the lake prior to recent environmental changes.

ABSTRACT This study was conducted between February and May 2019 on mature Cornu aspersum in the Black Sea region, Turkey to investigate the effects of different hibernation situations on reproductive responses. Three snail groups were studied: NH (natural hibernation), ASH (artificial short hibernation) and ALH (artificial long hibernation). NH showed inactive behaviour and had no reproductive activity while ASH and ALH performed intensive reproduction. During the experiment, the mean spawning rate (SpR), egg number (EgN), hatching rate (HR) and offspring number (OfN) were 20.50 ± 1.69%, 100.10 ± 5.22, 85.63 ± 2.36 and 80.69 ± 5.44 in the ASH group; 23.43 ± 3.36%, 122.33 ± 7.62, 61.55 ± 10.76 and 70.26 ± 11.60 in the ALH group, respectively. In conclusion, the high temperatures in the winter months of 2019 may have caused NH snails to become reproductively inactive, or it could simply be a consequence of their life-history strategy. Snails in the ASH and ALH groups represented a resource allocation trade-off between fecundity and survival to carry the genetic information to the next generation. This study leads to a better understanding of land snail reproductive physiology and behavioural responses to different hibernation conditions.

ABSTRACT Sepiolidae (Cephalopoda: Sepiolida) are growing in popularity as model organisms, not least because of their well-studied symbiotic relationship with light producing bacteria. Their easy maintenance and cultivation requirements in captivity have further facilitated their use in a wide range of developmental, anatomical, neurophysiological, behavioural and genetic studies, exhibiting promising opportunities for these cephalopods in research. Considering the rising interest in sepiolids, a detailed overview of their behavioural ecology is necessary to understand their evolution and conservation, as well as to aid establishment of good welfare practice when held in captivity. To date, not all aspects of the sepiolid ecology have been investigated in detail, and our current knowledge of their behavioural ecology is, for the most part, restricted to descriptions from less than 10 of the approximately 80 species, occasionally resulting in a generalisation of specific observations across species, genera, or even subfamilies. This review summarises current knowledge on sepiolid behavioural ecology and life history, including discussions on their habitat, life span, activity patterns, hunting and feeding behaviour, anti-predator behaviour, burying behaviour, and reproductive behaviour. Moreover, future directions as well as areas of interest for upcoming research studies are highlighted.

ABSTRACT A series of deep-sea expeditions in southeastern Australia has produced a considerable amount of conoidean (Gastropoda: Neogastropoda) material suitable for molecular and morpho-anatomical study. Previous and ongoing studies have revealed the Raphitomidae to be particularly diverse in the deep waters of this region. Here, we continue our conoidean investigation, focussing on the genera Comispira (Cochlespiridae) and Leucosyrinx (Pseudomelatomidae). We subjected two cytochrome oxidase subunit DNA sequence datasets of Conoidea to Automatic Barcode Gap Discovery (ABGD), which recognised a total of 18 primary species hypotheses (PSHs) among our target genera as well as from the cochlespirid genera Sibogasyrinx and Aforia. Following additional evaluation of shell and radular features, as well as examination of geographic and bathymetric ranges (conducted for PSHs of Australian waters), eight of these PSHs were converted to secondary species hypotheses (SSHs). Of these, three SSHs (one Comispira species, two Leucosyrinx spp.) were recognised as new to science and their full systematic descriptions are provided herein. While we discuss the relatively low diversity of Cochlespiridae compared to most conoidean families, two Comispira species and one species of Aforia are here recorded for the first time from Australian waters. http://zoobank.org/urn:lsid:zoobank.org:pub:0D342202-1901-4379-9EA8-6E7C1A4AAD7B

Of these, three SSHs (one Comispira species, two Leucosyrinx spp.) were recognised as new to science and their full systematic descriptions are provided herein. While we discuss the relatively low diversity of Cochlespiridae compared to most conoidean families, two Comispira species and one species of Aforia are here recorded for the first time from Australian waters. http://zoobank.org/urn:lsid:zoobank.org:pub:0D342202-1901-4379-9EA8-6E7C1A4AAD7B","PeriodicalId":18857,"journal":{"name":"Molluscan Research","volume":null,"pages":null},"PeriodicalIF":1.0,"publicationDate":"2022-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46261897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT A new species of land snail, Carychium jochumae n. sp., is described from northern Pakistan, representing a new country record for the genus. The new species is compared to the nominal species occurring on the Indian subcontinent: Carychium indicum Benson, 1849, C. boysianum Benson, 1864, C. khasiacum Godwin-Austen, 1876, and C. parietidentatum (Das & Aravind, 2021), which are briefly discussed. urn:lsid:zoobank.org:pub:42EDF7BD-6C22-4918-B4F7-DFB0BF85A8FA
