Introduction
The focus of my research is the biogeography, palaeontology, taxonomy and ecology of terrestrial microgastropods, and especially those belonging to the ellobioid family, Carychiidae. My work emphasises an integrative taxonomic approach including CT and SEM investigation of shells, molecular analyses and histology. Ecological investigation delves into their superficial subterranean and subterranean habitats. A large scale revision is in progress.

Article
Burmese amber continues to provide unique insights into the terrestrial biota inhabiting tropical equatorial forests during mid-Cretaceous time. In contrast to the large amount and great diversity of terrestrial species retrieved so far, aquatic biota constitute rare inclusions. Here we describe the first freshwater snail ever preserved in amber. T...

When seldom life history events serendipitously get documented by exceptional preservation in the fossil record, a unique telescopic opportunity arises for interpreting fossils within their paleoenvironment as well as for understanding ancestral relationships of current life forms. We present a rare glimpse of live birth by a terrestrial mother sna...

The subterranean realm of the Cantabrian-Pyrenean region of northern Spain harbours a rich diversity of Zospeum . Due to their tiny size and the difficulty of finding them alive, scarce animal material has been available for scientific investigation. Recent investigations of Zospeum shells have provided valuable, but limited insights towards our un...

Recent integrative investigations of the terrestrial ellobiid genus, Zospeum, have revealed significant findings concerning its Alpine-Dinaric evolution and taxonomy. Due to the expected discrepancy between the useful, but limited, 1970s' classification system based on shell data and the results of recent genetic analyses in the latest investigatio...

Two new, extremely small land snail species, Angustopila coprologos Páll-Gergely, Jochum & Hunyadi n. sp. and Angustopila psammion Páll-Gergely, Vermeulen & Anker n. sp. are described from northern Vietnam and northern Laos, respectively. The former is characterized by a rough surface sculpture and bears tiny mud granules arranged in a pattern of r...
Article
Land snails in mid-Cretaceous Burmese amber (ca. 99-98 Ma) have attracted great interest from paleontologists in recent years. Here we describe a new species of the genus Archaeocyclotus belonging to the family Cyclophoridae, from a well-preserved fossil, using classic light microscopy and modern micro-CT scans with computer 3D reconstructions. The...

Caves of Zospeum’s Eastern Alpine and Dinaride range have historically been unevenly sampled such that the northern half of the distribution is richly represented by shells in certain European museum collections while that of the southernmost, Croatian and Western Balkan extension is hardly known. Up to now, only one southern Dinaride species has b...

As part of a two-week school internship during 30.6.-14.7.2021, an ecological and faunistic study was undertaken to assess the malacofauna of a small pond within the Taunus Nature Park in the central upland range of the Taunus in the German federal state of Hesse. The Wellbach pond is easily accessible, and the project could be concepted and comple...

The genus Laoennea (Streptaxoidea, Diapheridae) was erected by Páll-Gergely, 2020. The type species, Laoennea carychioides Páll-Gergely, A. Reischütz & Maassen, 2020 is so far only known from the type locality cave in Laos. Herein, we describe a second species, Laoennea renouardi sp. nov., from a nearby cave in the same karst region of Vientiane Pr...

Excellently preserved fossils often provide important insights into evolutionary histories and adaptations to environmental change in Earth's biogeologic record. Mid-Cretaceous Burmese amber, for example, is a proven reservoir for spectacular findings. Here we document the first record of a fossil land snail with periostracal hairs preserved in amb...

Computed tomographic (CT) imaging allows new accessibility to shells of gastropod fossil taxa and their extant relatives, providing new data for interpreting former systematic assignments. The highly questionable ellobiid assignment of the nonmarine gastropod genus Protocarychium Pan, 1982 from the Lower Jurassic of Hunan, China, is reevaluated usi...

An integrative taxonomic investigation of carychiid microsnails of the troglobitic genus Zospeum in the Eastern and Dinaric Alps using 5 genetic markers (COI, 16S, H3, ITS2, 28S), species delimitation methods (ABGD, SP, and BPP) and morphometry, (Gastropoda, Ellobioidea, Carychiidae).

Yu et al. (in press) recently described two new species of gastropods from the Cretaceous Burmese amber and attributed them to the marine family Epitoniidae. A close inspection of the images provided by Yu et al. indicates however that the species in question do not belong to that family or any marine gastropod group. In contrast, the two species a...

The minute snails of the troglobitic genus Zospeum are known from the southeastern Alps through the Dinarides and from the Pyrenees to the Cantabrian Mountains. The majority of Zospeum has been described from the northernmost region of Southeast Europe, the geographical focus of our study. The taxonomic value of the few available morphological shel...

The present study aims to clarify the confused taxonomy of Z. schaufussi von Frauenfeld, 1862 and Zospeum suarezi Gittenberger, 1980. Revision of Iberian Zospeum micro snails is severely hindered by uncertainties regarding the identity of the oldest Iberian Zospeum species, Z. schaufussi von Frauenfeld, 1862. In this paper, we clarify its taxonomic...

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 this fourth EL lacked shell material post molecular analyses to serve as voucher material in a museum collection, it remained undescribed. Now, after recent collection effo...

The Hypselostomatidae Zilch, 1959 comprise a family of minute pupilloid snails usually endemic to limestone habitats in single hills, adjacent hill ranges, and in caves of Southeast Asia. Except for one molecular study, their taxonomy is largely conchologically driven. In this work, shell material derived from sediment samples from the Cong Troi Ca...

The minute troglobitic species, Zospeum isselianum Pollonera, 1887 (Eupulmonata: Ellobioidea, Carychiidae) is widely distributed within its Southern Alpine-Dinaric range. Its broad distribution and highly variable shell has caused this species to be historically lumped into its current taxonomic state of ambiguity. In an integrative taxonomic appro...

A new genus of troglobitic Carychiidae Jeffreys, 1830 is designated from Nodong Cave, North Chungcheong Province, Danyang, South Korea. This remarkable find represents a great range extension and thus, a highly distant distribution of troglobitic Carychiidae in Asia. The Zospeum-like, carychiid snails were recently included, without a formal descri...

Microgastropods include snails of different systematic rank and position. Due to their small size (< 2mm), investigation of internal structures is requisite particularly when species of different groups cannot be differentiated from each other. Since efficient, non-destructive tools are needed to navigate hazy taxonomic identifications while preser...

Background Current biodiversity patterns are considered largely the result of past climatic and tectonic changes. In an integrative approach, we combine taxonomic and phylogenetic hypotheses to analyze temporal and geographic diversification of epigean (Carychium) and subterranean (Zospeum) evolutionary lineages in Carychiidae (Eupulmonata, Ellobio...
