Species discovery and validation methods were used to delimit the species of a cryptic species complex. Species boundaries were inferred from multiple lines of evidence arising from mitochondrial and nuclear DNA sequencing and ecological niche modelling. Phylogenetic relationships among species were assessed by Bayesian inference and maximum‐likelihood procedures. The approach was applied to the terrestrial gastropod genus Pyramidula. By examining 211 specimens collected from the Western…

Molecular species delimitation refines the taxonomy of native and nonnative physinine snails in North America
TLDR
This work targeted an array of single-locus species delimitation methods at publically available specimens and new specimens collected from the Snake River basin, USA to generate species hypotheses, corroborated using nuclear analyses of the newly collected specimens.
Phylogeny and taxonomic reassessment of jerboa, Dipus (Rodentia, Dipodinae), in inland Asia
TLDR
It is found that individuals from more humid areas or higher altitudes were larger, whereas individuals from drier areas possessed longer appendages and larger tympanic bulla.
Species limits, interspecific hybridization and phylogeny in the cryptic land snail complex Pyramidula: The power of RADseq data.

TLDR
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.
Species delimitation and evolutionary reconstruction within an integrative taxonomic framework: a case study on Rhinolophus macrotis complex (Chiroptera: Rhinolophidae).
Phylogeny and molecular species delimitation of long-nosed armadillos (Dasypus: Cingulata) supports morphology-based taxonomy
TLDR
The phylogeny recovered three main lineages of long-nosed armadillos that the authors treat as subgenera (Hyperoambon, Muletia and Dasypus) and identified the majority of its diversification as having occurred during the Pliocene.
Species validation and cryptic diversity in the Geophagus brasiliensis Quoy & Gaimard, 1824 complex (Teleostei, Cichlidae) from Brazilian coastal basins as revealed by DNA analyses
TLDR
The present work evaluated the number of evolutionary units in this fish complex along hydrographic basins in northeastern Brazil by using the DNA barcode, species delimitation algorithms and phylogenetic analyses, and found the undescribed taxa in coastal basins of northeastern Brazil were clearly differentiated from Geophagus brasiliensis sensu stricto.
Phylogeny, taxonomic reassessment and ‘ecomorph’ relationship of the Orientallactaga sibirica complex (Rodentia: Dipodidae: Allactaginae)
TLDR
Molecular analyses reveal that the OSC more easily forms deeply divergent lineages in the foothills and this differentiation depth may be related to mountain system size.
Morphometrics and phylogeography of the cave-obligate land snail Helicodiscus barri (Gastropoda, Stylommatophora, Helicodiscidae)
TLDR
This study attempts to diagnose the potential cryptic diversity in the troglobitic land snail Helicodiscus barri, and discusses the delimitation and morphometric results and additionally provides discussion on the taxonomic and conservation implications.
Delimitation despite discordance: Evaluating the species limits of a confounding species complex in the face of mitonuclear discordance
TLDR
This study provides an empirical and integrative hypothesis testing framework to assess species delimitation hypotheses in the face of cryptic morphology and mitonuclear discordance and highlights the importance that a stable taxonomy has over conservation‐related actions.

Adding more ecology into species delimitation: ecological niche models and phylogeography help define cryptic species in the black salamander (Aneides flavipunctatus).
TLDR
This work demonstrates the ease and utility of using spatial analyses of environmental data and phylogenetics in species delimitation, especially for groups displaying fine-scaled endemism and cryptic species.
Ecological Niche Modelling and nDNA Sequencing Support a New, Morphologically Cryptic Beetle Species Unveiled by DNA Barcoding
TLDR
The use of nDNA and bioclimatic modelling in a new species of aquatic beetle revealed by mtDNA sequence data and extended use of mitochondrial sequences shows great potential for delineating morphologically cryptic species.
Comparing the efficacy of morphologic and DNA-based taxonomy in the freshwater gastropod genus Radix (Basommatophora, Pulmonata)
TLDR
Contrary to DNA-taxonomy, shell morphology was not suitable for delimiting and recognising species in Radix and is proposed as a reliable, comparable, and objective means for species identification in biological research.
Applications of ecological niche modeling for species delimitation: a review and empirical evaluation using day geckos (Phelsuma) from Madagascar.
TLDR
It is concluded that ecological niche modeling offers great potential for species delimitation, especially for taxonomic groups exhibiting low vagility and localized endemism and for groups with more poorly known distributions, and should be especially sensitive for detecting recent parapatric speciation driven by ecological divergence.
Molecular phylogeny, taxonomy and evolution of the land snail genus Iberus (Pulmonata: Helicidae)
TLDR
According to spatial patterns of sequence divergence, life habits and shell morphology may be concluded that the keeled-flat shelled snails independently originated several times within Iberus and they could represent cases of similar shell adaptation to a karstic arid environment.
Canarian land snail diversity: conflict between anatomical and molecular data on the phylogenetic placement of five new species of Napaeus (Gastropoda, Pulmonata, Enidae)
TLDR
Five new species of land snail are described from La Gomera (Canary Islands) of which the majority, on the basis of anatomy alone, could be incorporated within a new supraspecific taxon, and it is suggested that this group may be an excellent model for further studies of adaptation and diversification.
Molecular and morphological data reveal cryptic taxonomic diversity in the terrestrial slug complex Arion subfuscus/fuscus (Mollusca, Pulmonata, Arionidae) in continental north‐west Europe
TLDR
Morphological, morphological, allozyme and mitochondrial 16S rDNA sequence data have been jointly evaluated and gonad type proved to be a useful character for distinguishing the two species in north-west Europe.

Quantifying ecological, morphological, and genetic variation to delimit species in the coast horned lizard species complex (Phrynosoma)
TLDR
The hypothesis that the 3 phylogeographic groups distributed across California each represent distinctive species is not supported by all of the operational species criteria evaluated in this study, but the conservation status of the imperiled populations represented by these genealogical units remains critical.
SpedeSTEM: a rapid and accurate method for species delimitation
TLDR
This work enables speciation investigations to identify lineages that are evolutionarily distinct and thus have the potential to form new species before these lineages acquire secondary characteristics such as reproductive isolation or morphological differentiation that are commonly used to define species.
