On the origin of cryptic species: Insights from the Stygocapitella species complex

open access: yes, 2020
Biologists typically distinguish species by how they look. However, with the development of DNA-based techniques to identify species, they found that genetically-different species may look remarkably similar.

Cryptic species composition and genetic diversity within Bemisia tabaci complex in soybean in India revealed by mtCOI DNA sequence

open access: yesJournal of Integrative Agriculture, 2015
Bemisia tabaci is a cryptic species complex, causing significant loss on many agriculturally important crops worldwide. Knowledge on species composition and diversity within B.

Variation in heat shock protein 40 kDa relates to divergence in thermotolerance among cryptic rotifer species

open access: yesScientific Reports, 2022
Genetic divergence and the frequency of hybridization are central for defining species delimitations, especially among cryptic species where morphological differences are merely absent.

Cryptic Species Diversity and Phylogenetic Relationship in the Rust Genus Chrysomyxa from China

open access: yesJournal of Fungi, 2022
Chrysomyxa rusts are fungal pathogens widely distributed in the Northern hemisphere, causing spruce needle and cone rust diseases, and they are responsible for significant economic losses in China.

A molecular phylogeny of nuclear and mitochondrial sequences in Hymenolepis nana (Cestoda) supports the existence of a cryptic species [PDF]

open access: yes, 2002
Since isolates of Hymenolepis nana infecting humans and rodents are morphologically indistinguishable, the only way they can be reliably identified is by comparing the parasite in each host using molecular tools. In the current study, isolates of H. nana

Cryptic diversity of the subfamily Calaphidinae (Hemiptera: Aphididae) revealed by comprehensive DNA barcoding. [PDF]

open access: yesPLoS ONE, 2017
Aphids are a species rich group comprising many important pests. However, species identification can be very difficult for aphids due to their morphological ambiguity. DNA barcoding has been widely adopted for rapid and reliable species identification as

Using complementary techniques to distinguish cryptic species: A new Erysimum (Brassicaceae) species from North Africa [PDF]

open access: yes, 2011
• Premise of the study : Cryptic species are superfi cially morphologically indistinguishable and therefore erroneously classifi ed under one single name. The identifi cation and delimitation of these species is usually a diffi cult task.

Multilevel fine-scale diversity challenges the ‘cryptic species’ concept. [PDF]

open access: yes, 2019
‘Cryptic’ species are an emerging biological problem that is broadly discussed in the present study. Recently, a cryptic species definition was suggested for those species which manifest low morphological, but considerable genetic, disparity. As a case

Restricted Gene Flow among Lineages of Thrips tabaci Supports Genetic Divergence Among Cryptic Species Groups. [PDF]

open access: yesPLoS ONE, 2016
Knowledge of the relative influence of population- versus species-level genetic variation is important to understand patterns of phenotypic variation and ecological relationships that exist among and within morphologically indistinguishable cryptic ...
