Cryptic species could represent a substantial fraction of biodiversity. However, inconsistent
definitions and taxonomic treatment of cryptic species prevent informed estimates of their …

Restriction site‐Associated DNA sequencing (RAD‐seq) has become a widely adopted
method for genotyping populations of model and non‐model organisms. Generating a …

Most new cryptic species are described using conventional tree‐and distance‐based
species delimitation methods (SDMs), which rely on phylogenetic arrangements and …

Methods for species delimitation using molecular data have developed greatly and have
become a staple in systematic studies of clitellate worms. Here we give a historical overview …

In the absence of nuclear-genomic differentiation between two populations, deep
mitochondrial divergence (DMD) is a form of mito-nuclear discordance. Such instances of …

Restriction site‐associated DNA sequencing (RADseq) has emerged as a useful tool in
systematics and population genomics. A common feature of RADseq data sets is that they …

Cryptic mitochondrial (mt) lineages are known to exist in the earthworm morphospecies
Lumbricus rubellus and L. terrestris. The latter was recently split into two species, L. terrestris …

Cytoplasmic male sterility (CMS) is a form of genetic conflict over sex determination that
results from differences in modes of inheritance between genomic compartments. 1–3 …

Eisenia nordenskioldi pallida Malevič 1956 (Lumbricidae, Annelida) is widely distributed in
various climatic zones of Northern Asia. To study its genetic variation, we collected …

Research on cryptic species complexes has reached a consensus on the necessity of
integrating multiple sources of evidence. Reduced representation library techniques such as …
