Cryptic species in putative ancient asexual darwinulids (Crustacea, Ostracoda). [PDF]

open access: yesPLoS ONE, 2012
Fully asexually reproducing taxa lack outcrossing. Hence, the classic Biological Species Concept cannot be applied.We used DNA sequences from the mitochondrial COI gene and the nuclear ITS2 region to check species boundaries according to the evolutionary

Cryptic fungal species unmasked [PDF]

open access: yesMicrobiology Australia, 2012
The word cryptic is derived from the Greek adjective kruptós which means hidden. Morphologically indistinguishable species that have been revealed by molecular phylogenetic methods, and 37ultimately only recognised by their DNA sequences, are referred to as cryptic species.

How we study cryptic species and their biological implications: A case study from marine shelled gastropods

open access: yesEcology and Evolution, 2023
Methodological and biological considerations are intertwined when studying cryptic species. A potentially large component of modern biodiversity, the frequency of cryptic species among taxonomic groups is not well documented.

What lies behind the curtain: Cryptic diversity in helminth parasites of human and veterinary importance

open access: yesCurrent Research in Parasitology and Vector-Borne Diseases, 2022
Parasite cryptic species are morphologically indistinguishable but genetically distinct organisms, leading to taxa with unclear species boundaries. Speciation mechanisms such as cospeciation, host colonization, taxon pulse, and oscillation may lead to ...

Cryptic species within cryptic moths: new species of Dunama Schaus (Notodontidae, Nystaleinae) in Costa Rica [PDF]

open access: yesZooKeys, 2013
Based on almost 1,700 recently reared and wild-collected specimens, the genus Dunama Schaus (Notodontidae, Nystaelinae) in Costa Rica is reviewed. Eight species are recorded of which seven are newly described: Dunama jessiehillae Chacón, Dunama jessiebarronae Chacón, Dunama janewaldronae Chacón, Dunama jessiebancroftae Chacón, Dunama janecoxae Chacón ...

Climatic niche comparison across a cryptic species complex [PDF]

open access: yesPeerJ, 2019
According to current molecular evidence, the Chionaspis pinifoliae heterophyllae species complex has been recognized as 10 cryptic species. In this study, we construct potential distribution maps for seven cryptic species based on climatic variables ...

Assessing cryptic marine fauna diversity as underwater macrophotography (UMP) objects in Sempu Strait, Indonesia [PDF]

open access: yesE3S Web of Conferences, 2020
Cryptic marine fauna refers to organisms that live inside habitats that hidden from direct exposure to their outer environment. Its cryptic nature made these animals rarely observed, and hence understudied.
