Traditional species delimitation only based on morphological diagnostics does not fully meet the needs of modern taxonomy. Cryptic diversity revealed by molecular evidence has been increasingly discovered in many groups; however, subsequent species description is often lacking because of inadequate taxonomy and being devoid of operational criteria. In this study, we focus on the collembolan Coecobrya which has been suspected to be a species complex living on cave guanos. Our study aimed to… Expand
Colouration, chaetotaxy and molecular data provide species-level resolution in a species complex of Dicranocentrus (Collembola : Entomobryidae)
TLDR
An integrative approach to the genus Dicranocentrus in China is taken, where several members of the genus have been morphologically grouped as a species complex based on having paired outer teeth on unguis and seven colour patterns and revealed that speciation events likely occurred during the late Neogene. Expand
Integrative taxonomy uncovers hidden species diversity in the rheophilic genus Potamometra (Hemiptera: Gerridae)
TLDR
This study integrated molecular and morphological data for delimiting species boundaries and understanding the evolutionary history of the genus Potamometra to emphasize that the combination of molecular sequence data, morphological characters and mitochondrial structural information could improve the accuracy of species delimitation. Expand
Molecular diversity and species delimitation in the family Gasteruptiidae (Hymenoptera: Evanioidea).
TLDR
The results suggest that the incorporation of molecular species delimitation techniques provides a powerful tool to assist in the interpretation of species and help direct informed decisions with taxonomic uncertainty in the Gasteruptiidae family. Expand
Cryptic diversity in ant‐mimic Micaria spiders (Araneae, Gnaphosidae) and a tribute to early naturalists
TLDR
The data suggest the clear delineation of two distinct species, which supports the conception of 19th century taxonomists, and re‐circumscribe M. pulicaria and revalidate the long forgotten M. micans. Expand
Testing DNA barcodes against morphology for the ‘tripectinate Abantiades' (Lepidoptera: Hepialidae) reveals a complex relationship between COI sequence data and morphology
TLDR
Overall, the mitochondrial COI diversity of the ‘tripectinate‐Abantiades' can be divided into three major groups, with a majority of the species found in the semi‐arid regions of South Australia and Western Australia. Expand
New morphological and molecular data reveal an important underestimation of species diversity and indicate evolutionary patterns in European Lepidocyrtus (Collembola : Entomobryidae)
Abstract. The correct identification of morphological species is a key task for species richness estimation of any ecosystem. Although body colour is a widely used character identifying EuropeanExpand
Subterranean Deuteraphorura Absolon, 1901, (Hexapoda, Collembola) of the Western Carpathians — Troglomorphy at the northern distributional limit in Europe
TLDR
The results of the study enhance the importance of the Western Carpathians regarding the diversity pattern of obligate cave species in Europe and indicates that each studied population may represent a cryptic species. Expand
Distribution pattern and radiation of the European subterranean genus Verhoeffiella (Collembola, Entomobryidae)
TLDR
The combination of this extensive subterranean radiation and close evolutionary links with epigean relatives makes Verhoeffiella an exceptional case within the subterranean fauna of temperate areas, which significantly contributes to the authors' understanding of subterranean colonization and diversification patterns. Expand
Habitat selection, cryptic diversity, phylogeny, and phylogeography of the European Lepidocyrtus lanuginosus species group (Collembola: Entomobryidae)
TLDR
The results indicate that genetic markers are a reliable and fast method to detect cryptic species, which may facilitate taxonomic research on Collembola species and the identification of possible species-specific morphological characters. Expand
Mitogenomic data to study the taxonomy of Antarctic springtail species (Hexapoda: Collembola) and their adaptation to extreme environments
TLDR
The molecular features of the mitochondrial genome of Cryptopygus terranovus, a springtail species endemic to Victoria Land, are described and data does indicate positive selection, suggesting that survival at extreme environmental conditions could be also related to mtDNA modifications. Expand

It is proposed that incorporation of the explicit species delimitation criteria developed for this study will result in a substantial advance in the identification and description of species in understudied taxa. Expand
Multilocus species delimitation in a complex of morphologically conserved trapdoor spiders (mygalomorphae, antrodiaetidae, aliatypus).
TLDR
This study investigates species limits in a complex of morphologically conserved trapdoor spiders from California and provides a framework for identifying and defining the cryptic lineage diversity that prevails in many organismal groups. Expand
Challenging species delimitation in Collembola: cryptic diversity among common springtails unveiled by DNA barcoding
TLDR
Several populations of six well characterised species of springtails were sequenced using the COI barcode fragment as a contribution to the global Collembola barcoding campaign, and each species showed high intraspecific divergence. Expand
Cryptic Diversity in the Ubiquist Species Parisotoma notabilis (Collembola, Isotomidae): A Long-Used Chimeric Species?
TLDR
The sequencing of the barcoding fragment for several populations throughout Europe and North America revealed four distinct genetic lineages, and the species name was successfully assigned to one of these lineages. Expand
Collembola, the biological species concept and the underestimation of global species richness
TLDR
It is speculated that global species richness of Collembola could be at least an order of magnitude greater than a previous estimate of 50 000 species. Expand
Phylogeny of Collembola based on cuticular compounds:inherent usefulness and limitation of a character type
TLDR
In this study the usefulness of a new character type not previously used in the phylogenetic study of Collembola was tested: the epicuticular chemical compounds, and this character type is appropriate for reconstructing phylogenetic relationships among recently diversified groups. Expand
Morphological and molecular insights on Megalothorax: the largest Neelipleona genus revisited (Collembola)
TLDR
The genus Megalothorax Willem is redefined along with a redescription of the type species M. minimus Willem, 1900 and the description of five new species and broad sets of characters are described and commented on. Expand
Cryptic diversity, diversification and vicariance in two species complexes of Tomocerus (Collembola, Tomoceridae) from China

Diversification analyses suggest that the subsequent orogenesis of the Qinghai–Tibetan Plateau in western China had little impact on divergences within the two species complexes so that they maintained their geographical patterns from the Paleogene to the present day. Expand

TLDR
Analysis of DNA sequences for the COI and 28S genes is congruent with species-level groups delimited by chaetotaxy, and provide additional support for chaetOTaxy as the most reliable morphological character system to distinguish species in Plutomurus. Expand
