Molecular studies have recently led to the detection of many cryptic species complexes within morphologically ambiguous species formerly undescribed by the scientific community. Organisms such as land snails are at a particularly higher risk of species misidentification and misinterpretation, in that gastropod systematics are based almost entirely on external shell morphology. Subterranean ecosystems are associated with especially high degrees of cryptic speciation, largely owing to the abiotic…

Phylogeography and potential glacial refugia of terrestrial gastropod Faustina faustina (Rossmässler, 1835) (Gastropoda: Eupulmonata: Helicidae) inferred from molecular data and species distribution models

The genetic data as well as shell phenotypes showed considerable variation within and between studied populations, the molecular species delimitation approaches still imply only one single species.

Phylogenetic relationships among subclades within the Trinity bristle snail species complex, riverine barriers, and re-classification

DNA sequence analysis and PCR sequencing revealed that sparsely bristled Trinity bristle snails were generally found to the northwest and more abundantly bristled individuals to the southeast in relation to primary river corridors that bisect the central Trinity Basin, while a similar but opposite trend was observed in the directional pattern of banding.

Molecular phylogenetic analysis of Punctoidea (Gastropoda, Stylommatophora)

It is suggested that Charopidae be retained as a family-level group for now, pending further study of the systematic relationships of its constituent taxa, and a new superfamily, Discoidea, is erected here for two Northern Hemisphere families, Discidae and Oreohelicidae, which were previously assigned to Punctoidea.

Redescription of Monacha pantanellii (De Stefani, 1879), a species endemic to the central Apennines, Italy (Gastropoda, Eupulmonata, Hygromiidae) by an integrative molecular and morphological approach

This research confirmed that the species of Monacha and their molecularly distinguished lineages can only occasionally be recognised morphologically and that they have significant inter- and intra-population variability.

A new species of stygobitic snail in the genus Antrorbis Hershler & Thompson, 1990 (Gastropoda, Cochliopidae) from the Appalachian Valley and Ridge of eastern Tennessee, USA

This is the first cavesnail to be described from the Appalachian Valley and Ridge (AVR) physiographic province in the state of Tennessee, which previously represented a substantial gap in the distribution of stygobitic gastropods.

The Effects of Different Habitats and Morphological Variability on Cryptozona siamensis (Pfeiffer, 1856) in Chiang Mai Province

DNA fingerprint analysis based on high annealing temperature randomly amplified polymorphic DNA, cytochrome c oxidase subunit I (COI) markers, genitalia and geometric morphometric analysis of shell shape suggest that variation has occurred in C. siamensis snails from different habitats.

Biodiversity from caves and other sub-terranean habitats of Georgia, USA

We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including


The new species is distributed along coastal urban areas from southern Espírito Santo state to São Paulo state and can be diagnosed from its congeners by the following features: a comparatively small shell; the penultimate and body whorls bulging and rounded; and the lack of apertural lamellae/teeth.

Lampenflora and the entrance biofilm in two show caves: comparison of microbial community, environmental, and biofilm parameters

Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near




The use of recently developed methods for discovering and testing species boundaries and relationships using a multilocus dataset in a widely distributed subterranean teleost fish, Typhlichthys subterraneus, endemic to Eastern North America is used.

Phylogeography and morphological variability in land snails: the Sicilian Marmorana (Pulmonata, Helicidae)

The progressive decline in mitochondrial DNA sequence similarity over a distance of 250 km is consistent with a model of isolation by distance, a pattern previously recognized for other groups of land snails.

Caves as microrefugia: Pleistocene phylogeography of the troglophilic North American scorpion Pseudouroctonus reddelli

High genetic diversity, strong phylogeographical structure, diffusion from multiple refugia, and unfavourable climatic conditions at the LGM collectively support the hypothesis that caves served as microrefugia for P. reddelli at the Last Glacial Maximum.

Mitochondrial sequence data indicate “Vicariance by Erosion” as a mechanism of species diversification in North American Ptomaphagus (Coleoptera, Leiodidae, Cholevinae) cave beetles

A molecular phylogeny to examine the diversification of the hirtus-group of the small carrion beetle genus Ptomaphagus indicates populations being isolated by vicariant events as the southern Cumberland Plateau eroded and fragmented over millions of years.

Species delimitation for cryptic species complexes: case study of Pyramidula (Gastropoda, Pulmonata)

It is indicated that although shell characters serve to discriminate between some putative species, they are not sufficient as unique taxonomic characters and other lines of evidence are needed.

A new approach to an old conundrum—DNA barcoding sheds new light on phenotypic plasticity and morphological stasis in microsnails (Gastropoda, Pulmonata, Carychiidae)

It is demonstrated that the application of DNA barcoding can alleviate problems within the Carychiidae, a taxon of the pulmonate lineage and most likely migrated onto land independently of the Stylommatophora clade.

Molecular Phylogeny, Evolution of Shell Shape, and DNA Barcoding in Polygyridae (Gastropoda: Pulmonata), an Endemic North American Clade of Land Snails

A close, well-supported relationship between Mesodontini and Triodopsini, two tribes that were distantly related in Emberton's hypothesis are found, indicating an urgent need for revisionary taxonomy at all levels of classification in this family.

Caves as islands: mitochondrial phylogeography of the cave-obligate spider species Nesticus barri (Araneae: Nesticidae)

The mitochondrial phylogeographic structuring of the troglobitic spider Nesticus barri is studied, sampling individuals from twelve caves across the species' range, finding that N. barri populations within individual caves are generally not genetically diverse and female-based migration between caves is minimal or nonexistent.

Phylogeography of a subterranean amphipod reveals cryptic diversity and dynamic evolution in extreme environments

It is argued that future analyses of evolution and biogeography in subsurface, or more generally in extreme environments, should consider dispersal ability as an evolving trait and morphology as a potentially biased marker.
