“…In the last decade, the rise of molecular studies has greatly improved the detection of cryptic species (morphologically indistinguishable species) [1]–[7]. The importance of cryptic species lies in their contribution to overall biodiversity by increasing species richness at different scales and may also be due to the fact that they convey important information as fundamental units in biogeography, ecology, evolutionary studies [8], [9] and conservation biology [10]–[12].…”

“…The subterranean realm is a highly fragmented environment where strong directional selection operates. The fragmented nature of its habitats increases the possibility of speciation, whereas strong directional selection constrains the extent of morphological changes [5]–[7], [17]–[28]. Among aquatic subterranean taxa, cryptic species seem to be common [29].…”

Can Environment Predict Cryptic Diversity? The Case of Niphargus Inhabiting Western Carpathian Groundwater

et al. 2013

In the last decade, several studies have shown that subterranean aquatic habitats harbor cryptic species with restricted geographic ranges, frequently occurring as isolated populations. Previous studies on aquatic subterranean species have implied that habitat heterogeneity can promote speciation and that speciation events can be predicted from species’ distributions. We tested the prediction that species distributed across different drainage systems and karst sectors comprise sets of distinct species. Amphipods from the genus Niphargus from 11 caves distributed along the Western Carpathians (Romania) were investigated using three independent molecular markers (COI, H3 and 28S). The results showed that: 1) the studied populations belong to eight different species that derive from two phylogenetically unrelated Niphargus clades; 2) narrow endemic species in fact comprise complexes of morphologically similar species that are indistinguishable without using a molecular approach. The concept of monophyly, concordance between mitochondrial and nuclear DNA, and the value of patristic distances were used as species delimitation criteria. The concept of cryptic species is discussed within the framework of the present work and the contribution of these species to regional biodiversity is also addressed.

“…There are 58 species known for this particular region, 41 formally described, and at least 17 more that have been identified as new species, but are pending description. This includes many cryptic species identified thanks to molecular studies (Camacho et al, 2011, 2012, 2013a, b). All of the above are represented through permanent slices in the collection we present here, plus DNA extracts of 41 of the species, although currently not all of them include the gene sequences.…”

This is the first published database of a Bathynellacea Chappuis, 1915 collection of slices and DNA extracts. It includes all data of bathynellaceans (Crustacea: Syncarida) collected in the last 48 years (1968 to 2016) on the Iberian Peninsula and Balearic Islands, studied since 1984. It also includes specimens studied across many countries of Europe (Portugal, Romania, France, Italy, Slovenia, Bulgaria, and England), as well as some specimens obtained from samples of North America (Montana, Washington, Alaska and Texas), South America (Brazil, Chile and Argentina), Asia (China, Thailand, Vietnam, Mongolia and India), Africa (Morocco and Chad) and Australia (New South Wales –NSW- and Queensland). The samples come from groundwater (caves, springs, wells and hyporrheic habitat associated with rivers) obtained from both, sampling campaigns and occasional sampling efforts.The data set includes 3399 records (2657 slices and 742 DNA extracts) corresponding to three families (Parabathynellidae Noodt, 1965, Leptobathynellidae Noodt, 1965 and Bathynellidae Grobben, 1905) of the order Bathynellacea; the existence of three families is accepted, but this is a controversial issue and here is not the appropriate context to address this problem; 52 genera and 92 species formally described, in addition to 30 taxa under study and, thus, still unpublished. This represents more than half of all the genera known worldwide (80) and almost one third of the species currently known in the world (329, which increases every year).This dataset contains especially relevant collection that includes holotypes and type series of 43 new species of Bathynellacea (33 from the Parabathynellidae and ten from the Bathynellidae) described by Ana I. Camacho (AIC hereinafter); eleven of these are the type species for new genera described from all around the world, ten belonging to the Parabathynellidae and one from the Bathynellidae. As previously mentioned, these new species come from all continents, although 26 of them are from the Iberian Peninsula.The most important feature of this collection is that it has been created and reviewed by a specialist of the group (AIC), and each specimen, regardless of its shape (either permanent slices or DNA extracts), includes taxonomic, geographical and authorship information. The specialist has been involved in all stages of the process, from field sampling to the digitization of the results we are now presenting, and has worked in close collaboration with the curators responsible for the different collections involved in this project.

“…Many of these groups are relictual or exhibit phylogenetic isolation, and in some cases, high endemism has been reported (Gilbert & Deharveng 2002). Nevertheless, the knowledge is limited (Maurice & Bloomfield 2012), and distribution records are fragmentary (Knight & Penk 2010, Camacho et al 2012, Ferna´ndez 2004). …”
