Species delimitation and DNA barcoding for Chinese Mantodea (Insecta, Dictyoptera) [PDF]

open access: yesZooKeys
DNA barcoding has been proposed as a rapid and reliable tool for animal identification and species delineation. The 5’ end of the mitochondrial cytochrome c oxidase I gene (COI-5P) was sequenced for 318 specimens of 55 mantis species.

Uncertainties and risks in delimiting species of Cambeva (Siluriformes: Trichomycteridae) with single-locus methods and geographically restricted data [PDF]

open access: yesNeotropical Ichthyology, 2022
Cambeva contains species with complex taxonomy or poorly delimitated in terms of morphology and geopraphic distribution. We conducted an extensive review of Cambeva populations from coastal drainages of Southern to Southeastern Brazil to evaluate species

Delimiting Species-Poor Data Sets using Single Molecular Markers: A Study of Barcode Gaps, Haplowebs and GMYC [PDF]

open access: yesSystematic Biology, 2015
Most single-locus molecular approaches to species delimitation available to date have been designed and tested on data sets comprising at least tens of species, whereas the opposite case (species-poor data sets for which the hypothesis that all individuals are conspecific cannot by rejected beforehand) has rarely been the focus of such attempts.

Cryptic speciation in populations of the genus Aphyocharax (Characiformes: Characidae) from eastern Amazon coastal river drainages and surroundings revealed by single locus species delimitation methods

open access: yesNeotropical Ichthyology, 2021
Recent studies in eastern Amazon coastal drainages and their surroundings have revealed new fish species that sometimes exhibit little morphological differentiation (cryptic species).

Species delimitation of Margattea cockroaches from China, with seven new species (Blattodea, Ectobiidae, Pseudophyllodromiinae) [PDF]

open access: yesZooKeys, 2021
Nearly 450 Margattea specimens were collected from 27 locations in China and their morphology was examined. Then 68 Margattea COI sequences were obtained and used to carry out phylogenetic analyses as well as species delimitation analyses using General ...
