Boucardicus must have microtunnels! Reassignment of three species into Acroptychia (Gastropoda: Caenogastropoda: Hainesiidae)

Publication Name: Zootaxa

Publication Date: 2025-07-28

Volume: 5666

Issue: 2

Page Range: 287-293

Description:

Boucardicus is a Madagascan endemic genus of the family Hainesiidae (subfamily Boucardicinae). The over 200 known species are variable in terms of shell shape, but their common trait is the presence of pre-constriction ribs, under which microtunnels run. Here we report three Boucardicus species without microtunnels, and as a consequence, transfer them to the genus Acroptychia as follows: Acroptychia boulangeri (Fischer-Piette, C.P. Blanc, F. Blanc & Salvat, 1993), Acroptychia (?) culminans (Fischer-Piette, C. P. Blanc, F. Blanc & F. Salvat, 1993) and Acroptychia (?) optio (Fischer-Piette, C. P. Blanc, F. Blanc & F. Salvat, 1993). The variability of the genus Acroptychia is briefly discussed.

Molecular phylogeny of the operculated land snail family Pupinidae (Caenogastropoda, Cyclophoroidea) in mainland Southeast Asia

Publication Name: Zoologica Scripta

Publication Date: 2025-07-01

Volume: 54

Issue: 4

Page Range: 526-547

Description:

The operculated land snail family Pupinidae from mainland Southeast Asia has been systematically revised based on shell morphology. Despite previous morphological studies, the evolutionary relationships within this family remained unclear. This study represents the first comprehensive molecular phylogeny of this snail group, utilising two mitochondrial (COI and 16S rRNA) and two nuclear (5.8S rRNA + ITS2 and 28S rRNA) genetic markers. Additionally, we conducted phylogenetic analyses of Pupina species from 1106 loci generated through double-digest restriction site-associated DNA sequencing (ddRADseq). It turned out that Southeast Asian Pollicaria emerged as a sister clade to Central American Aperostoma of the Megalomastomatidae, leading to the resurrection of the Pollicariidae. Among the remaining pupinid genera, Tortulosa was nested within the Coptocheilus clade, while Pupina and Pupinella were not monophyletic. The previously recognised Pupina arula species group was found to be monophyletic and was reclassified into Tylotoechus (formerly a Pupina subgenus), based on distinctive conchological characters such as an extending parietal tooth from a parietal callus and a wide, outward-curving posterior canal. However, some Pupina and Tylotoechus species were not retrieved as monophyletic, suggesting the presence of multiple ‘cryptic species’. Divergence time estimation indicated that the Pupinidae split could date back to the Late Triassic to Early Cretaceous, with the first diversification of pupinid genera occurring during the Middle Jurassic and Early Cretaceous. This successful reconstruction of a robust phylogeny using ddRADseq loci demonstrates the significant potential of RADseq techniques in elucidating the evolutionary relationships of deeply divergent taxa. Further studies incorporating the type species Tylotoechus destructus and Pupina keraudrenii are necessary to justify the usage of these genera.

A new start? Revision of the genera Anauchen, Bensonella, Gyliotrachela and Hypselostoma (Gastropoda, Eupulmonata, Hypselostomatidae) of Southeast Asia with description of 46 new species

Publication Name: Zookeys

Publication Date: 2025-01-01

Volume: 1235

Issue: Unknown

Page Range: 1-338

Description:

Hypselostomatidae is a large family of terrestrial pulmonate molluscs currently represented by 284 extant species, most confined to Southeast Asia. The current system of grouping species into genera is based on the morphology of the apertural barriers and the level of last whorl detachment. However, these characters overlap, challenging generic definitions. In this paper, these characters are evaluated and a novel classification proposed for hypselostomatid species belonging to the genera Anauchen (17 species), Bensonella (36 species), Boysidia (7 species, in part) and Hypselostoma (85 species). We assigned all species belonging to the genera Bensonella and Hypselostoma into two and four species groups respectively, which are characterised by combinations of morphological traits. Altogether 46 new species are described, seven species in Anauchen: A. crassus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. evanidus Gojšina & Páll-Gergely, sp. nov., A. grandiportus Gojšina, Grego & Páll-Gergely, sp. nov., A. obesus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. picasso Gojšina & Páll-Gergely, sp. nov., A. turritus Gojšina, Hunyadi & Páll-Gergely, sp. nov., A. jokaii Gojšina & Páll-Gergely, sp. nov.; 19 species in Bensonella: B. alycaeus Gojšina & Páll-Gergely, sp. nov., B. cardiostoma Gojšina, Vermeulen & Páll-Gergely, sp. nov., B. cristatissima Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. dha Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. dracula Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. exploda Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. fracta Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. microdentata Gojšina & Páll-Gergely, sp. nov., B. mitochondria Gojšina, Vermeulen & Páll-Gergely, sp. nov., B. mirabilis Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. montawa Gojšina, Hunyadi & Páll-Gergely, sp. nov., B. multidentata Gojšina, A.

One replacement name is proposed: H. tertiusfrater Gojšina & Páll-Gergely, nom. nov. pro Boysidia salpinx F. G. Thompson & Dance, 1983, non Hypselostoma salpinx (van Benthem Jutting, 1961) (originally described as Gyliotrachela). Gyliotrachela and Antroapiculus are both treated as junior synonyms of Hypselostoma. An additional 28 species and subspecies are reassigned to the synonymies of other taxa.

Recurrent evolution of breathing microtunnel system in terrestrial operculate snails (Gastropoda: Caenogastropoda: Cyclophoroidea)

Publication Name: Zoological Journal of the Linnean Society

Publication Date: 2024-12-01

Volume: 202

Issue: 4

Page Range: Unknown

Description:

The Cyclophoroidea are a group of land snails possessing an operculum that seals the aperture when the snail withdraws its body into the shell. Several groups have developed snorkel-like tubes, which are open at their outer ends, for gas exchange when the operculum closes the aperture. The tube of the cyclophorid subfamily Alycaeinae is, however, closed at its outer end. Recent investigations revealed that the tube of Alycaeinae, which starts to develop in subadults, is connected to several long microtunnels that run perpendicular to the tube and open near the umbilicus. We examined snails similar to Alycaeinae and discovered three types of gas-exchange systems that differ from the system in Alycaeinae. In Laotia, the microtunnels run to separate chambers, whereas in Platyrhaphe the microtunnels run to an internal tube. In both genera, the breathing device is already present in juveniles. Lastly, in Boucardicus there is no tube, but the microtunnels reach the common opening individually. Our molecular phylogeny, based on sequence data from the 28S, H3 and COI genes indicates that the microtunnel systems of these four groups have evolved independently. Based on these findings, three new subfamilies are proposed: Boucardicinae Páll-Gergely subfam. nov. (Hainesiidae), Laotiinae Páll-Gergely subfam. nov. (Diplommatinidae), and Platyrhaphidinae Páll-Gergely subfam. nov. (Cyclophoridae).

Identification crisis: a fauna-wide estimate of biodiversity expertise shows massive decline in a Central European country

Publication Name: Biodiversity and Conservation

Publication Date: 2024-11-01

Volume: 33

Issue: 13

Page Range: 3871-3903

Description:

Expertise in biodiversity research (taxonomy, faunistics, conservation with taxonomic background) appears to decline worldwide. While the “taxonomic impediment” is discussed extensively in the literature, much fewer papers focus on the identification crisis, i.e., the decreasing number of experts who can identify species, and the decline of species-based biodiversity research. As a test case to explore the gravity of the identification crisis, we chose Hungary, a Central European country with a strong history of comprehensive taxonomic expertise and research output. We set out to answer two main questions. (1) What proportion of the Hungarian fauna could currently be identified by Hungarian experts, and what factors determine which groups are covered; and (2) what are the trends of biodiversity research in Hungary, and what are the underlying reasons for these trends? We show that Hungary lacks active biodiversity experts for almost half of the nearly 36,000 animal species recorded in the country, and more than a quarter of the fauna have only one or two active experts available. We also show that faunistic research experienced a golden era between ca. 1990 and 2010. Since then, however, there has been a strong decline, with the number of active experts and published papers decreased to a level like that of the 1970s. Multiple factors are identified causing this trend, such as increased pressure to publish in high impact journals and increasing administrative duties of professional scientists. The next generation of biodiversity experts needs to be fluent in modern techniques and publication strategies but also maintain robust morphology-based knowledge to be equipped for identification tasks of difficult taxa. Despite being disadvantaged by exclusive application of citation-based evaluation, we do need more positions and focused grants for biodiversity researchers to maintain the country’s knowledge base and to avoid being increasingly dependent on—equally declining—foreign expertise.

A new species of Landouria from Thailand, with a deep umbilical groove (Gastropoda, Stylommatophora, Camaenidae)

Publication Name: Ecologica Montenegrina

Publication Date: 2025-08-15

Volume: 89

Issue: Unknown

Page Range: 161-168

Description:

Landouria canalifera Páll-Gergely, Tumpeesuwan & Tumpeesuwan sp. nov. is described from Koh Samui, southern Thailand. It is characterized by a deep groove inside the umbilicus on the last ca. 1.5 whorls, corresponding with a columellar fold in the aperture. Also, there is a basal apertural tooth, corresponding with a shallow groove on the basal side of the shell just behind the peristome. These two barriers form a shallow canal in the aperture. Although the reproductive anatomy of this new species is not known, it probably belongs to the genus Landouria, which is widespread in Thailand and in the neighboring countries.

Molecular characterisation of the invasive terrestrial nemertean Geonemertes pelaensis: long and complex mitogenome and presence of NUMTs

Publication Name: Scientific Reports

Publication Date: 2026-12-01

Volume: 16

Issue: 1

Page Range: Unknown

Description:

The complete mitochondrial genome of the invasive terrestrial nemertean Geonemertes pelaensis Semper, 1863 (Nemertea: Prosorhochmidae) was sequenced from two specimens collected in geographically distant French overseas territories—Martinique in the Caribbean and New Caledonia in the South-West Pacific. In both specimens, the mitogenome contained 13 protein-coding genes, two rRNA genes, and 21 tRNA genes, and was unusually large, approaching 32 kb. The two genomes differed by only four single nucleotide polymorphisms and one indel. A comparison with 22 cox1 sequences available in GenBank confirmed this high level of genetic conservation, suggesting a recent introduction from related source populations. The extraordinary length of the mitogenome was largely attributable to two extended regions comprising only tRNA genes and long intergenic sequences. These results were contrasted with data from an unpublished SRA sequencing project (SRS20559370) of an unlocalized specimen identified as G. pelaensis; its reconstructed mitogenome was only 18 kb in length (14 kb shorter) and showed extensive sequence divergence. Phylogenetic analyses placed this specimen as the sister lineage to G. pelaensis, highlighting the need for further investigation of this taxon. In the Martinique specimen, several NUMTs (nuclear mitochondrial pseudogenes) were also detected, which could complicate future studies relying solely on Sanger sequencing. Sequencing additionally revealed prey DNA from the gut contents of both worms: the New Caledonian specimen had consumed an unidentified noctuid moth, while the Martinique specimen had likely fed on the invasive cockroach Periplaneta australasiae (Fabricius, 1775), itself an introduced species.

Volume: Unknown

Issue: 1272

Page Range: 1-31

Description:

The study on Cyclophoroidea from Padang Bindu Karst, South Sumatra, was conducted to document the species diversity of the superfamily in the area. The samples, including leaf litter and soil samples, were collected in May–June 2021 and followed by the determination and examination on 2023 to 2024 in the Museum Zoologicum Bogoriense. In total 3,780 specimens from the superfamily Cyclophoroidea were examined. Measurements of the shell and operculum were performed using L.A.S V4. 13.0 and IMAGE J. The research revealed 11 species from three families (Cyclophoridae, Diplomatinidae, Pupinidae) and four subfamilies. Plectostoma kitteli is the most abundant species followed by Stomacosmethis cf. jagori (19.84%) and Diplommatina liwaensis (6.67%). A new species, Chamalycaeus dayangmerindu Aulia & Nurinsiyah, sp. nov. is described. The study also discovered four species endemics to Sumatra with one species among them so far only recorded from Padang Bindu karst area. These findings emphasize the region’s unique biodiversity.

Disturbance and topography shape the capacity of microrefugia to support unique biodiversity

Publication Name: Ecological Indicators

Publication Date: 2026-04-01

Volume: 185

Issue: Unknown

Page Range: Unknown

Description:

Microrefugia play a key role in facilitating the persistence of biodiversity during climate change. Many occur in topographically complex landscapes shaped by various disturbances, but we know little about how the combined effects of topography and disturbance affect the capacity of refugia to support biodiversity. To better understand this, we inventoried taxonomic richness across four biological groups (soil microbiota, vascular plants, terrestrial snails, and ants), as well as climatic and soil conditions, in different microhabitats (south-facing slopes, north-facing slopes, and bottoms) of topographic depressions (dolines) and on the surrounding plateaus. Unique species assemblages and cooler, moister microclimatic conditions in dolines supported their importance as biodiversity hotspots and microrefugia. Relationships between indicators of disturbances (anthropogenic: historical logging; natural: canopy gaps) and species richness differed, depending on the biological group and microhabitat. While most biological groups seemingly recovered within 50 years following clear-felling, plants did not, highlighting the persistent impact of anthropogenic disturbances on refugial capacity. Plants were also the only group that displayed a significant response to the presence of small canopy gaps at doline bottoms, which promoted the occurrence of specific plant species. All biological groups displayed some response to microhabitats, although these responses differed among taxa. Therefore, high environmental heterogeneity appears to help facilitate the role of dolines as biodiversity hotspots and microrefugia. We conclude that the direction and magnitude of the effects of disturbances and topography are taxon-specific, due to species-specific responses to microenvironmental conditions. Disturbance history is an important consideration when identifying refugia for climate change management.

Angustopila milium (Gastropoda: Hypselostomatidae) is one of the most widespread land snail species in South and Southeast Asia, due to its conspecificity with A. elevata, syn. nov.

Publication Name: Zoosystematica Rossica

Publication Date: 2026-01-01

Volume: 35

Issue: 1

Page Range: 57-67

Description:

Angustopila elevata (Thompson et Upatham, 1997) was originally described from northern Thailand. It is the most widespread species within the genus Angustopila Jochum, Slapnik et Páll-Gergely, 2014, as revealed by a recent revision. The distribution of this species extends from southern Thailand through northern Laos and northern Vietnam to the Guangxi Zhuang Autonomous Region in Southern China. Based on shells recently collected in India, conspecificity was established between A. milium (Benson, 1853) and A. elevata, syn. nov. Furthermore, A. milium is reported from Nepal for the first time. Angustopila milium thus becomes the most widespread species of this genus and one of the most widely distributed land-snail species in South and Southeast Asia.
