Molecular systematics and species delimitation are highly dependent on phylogenetics. However, incomplete lineage sorting, hybridization, polyploidy and taxon identification difficulties can combine to make phylogenetics uncertain. We used the HYBseq method with the Angiosperm 353 bait kit to elucidate the relationships between Romulea taxa in the ...

In nucleotide public repositories, studies discovered data errors which resulted in incorrect species identification of several accipitrid raptors considered for conservation. Mislabeling, particularly in cases of cryptic species complexes and closely related species, which were identified based on morphological characteristics, was discovered. Pri...

Species delimitation is a powerful approach to assist taxonomic decisions in challenging taxa where species boundaries are hard to establish. European taxa of the blind mole rats (genus Nannospalax) display small morphological differences and complex chromosomal evolution at a shallow evolutionary divergence level. Previous analyses led to the reco...
BACKGROUND: The genus Triplostegia contains two recognized species, T. glandulifera and T. grandiflora, but its phylogenetic position and species delimitation remain controversial. In this study, we assembled plastid genomes and nuclear ribosomal DNA (nrDNA) cistrons sampled from 22 wild Triplostegia individuals, each from a separate population, an...

The oriental fruit fly Bactrocera dorsalis is one of the most destructive agricultural pests worldwide, with highly debated species delimitation, origin, and global spread routes. Our study intended to (i) resolve the taxonomic uncertainties between B. dorsalis and B. carambolae, (ii) reveal the population structure and global invasion routes of B....
Abstract DNA barcoding often fails to identify species despite its undisputed advantages. Hybridization, sample contamination, incomplete lineage sorting and nuclear copies of mitochondrial genes (NUMTs) are often put forward as explanations but have seldomly been tested. Here I used available RNA-sequencing data to explore this issue in four Chort...
An accurate taxa delimitation, based on a full understanding of evolutionary processes involved in taxon differentiation, can be gained from a combination of ecological, morphological, and molecular approaches. The taxonomy of Magnolia subsect. Talauma in Cuba has long been debated and exclusively based on a traditional morphological study of a lim...

Plant-feeding beetle species are diverse and often individually highly variable. Accurate classifications can be difficult to establish yet are essential for study of evolutionary patterns and processes. Molecular data are key to further characterizing morphologically difficult groups and defining genus and species boundaries. Monochamus Dejean spe...

Biological control and taxonomy are continuously developing fields with remarkable impacts on society. At least 80 years of literature have documented this relationship, which remains essentially the same in its mutualistic nature, as well as in its major challenges. From the perspective of Brazilian taxonomists, we discuss the impacts of important...
