The number of described species on the planet is about 1.9 million, with ca. 17,000 new annually, mostly from tropics. However, taxonomy usually as a science in crisis, lacking manpower and funding, politically acknowledged problem known Taxonomic Impediment. Using data Fauna Europaea database Zoological Record, we show that contrary to general belief, developed heavily-studied parts world are important reservoirs unknown species. In Europe, multicellular terrestrial freshwater animals being...
Abstract Valvatiform gastropods of the family Hydrobiidae are frequently found in European spring-fed systems. Their simplified and sometimes convergent morphological structures restricted geographical ranges make description identification valvatiform species challenging. In Iberian Peninsula, to date, 20 have been described morphologically. To test delimitations evaluate role physical geography on their evolutionary history, we analysed two mitochondrial (COI 16S rRNA) nuclear (28S rRNA...
Reliable taxonomy underpins communication in all of biology, not least nature conservation and sustainable use ecosystem resources. The flexibility taxonomic interpretations, however, presents a serious challenge for end-users concepts. Users need standardised continuously harmonised reference systems, as well high-quality complete data sets, but these are generally lacking non-specialists. solution is dynamic, expertly curated web-based tools.

The freshwater gastropod genus Pseudamnicola Paulucci, 1878 M. 1878. Matériaux pour servir à l'étude de la faune malacologique terrestre et fluviatile l´Italie ses isles, Paris: Librairie F. Savy, 54. [Google Scholar] belongs to the family Hydrobiidae Stimpson, 1865 and has been cited in Europe, Africa Asia. Ibero-Balearic region is considered one of areas showing greatest diversity hydrobiids although few works have provided complete morphological descriptions. Seven species described based...
The freshwater snail genus Mercuria is widely distributed in lowland waters across Western Europe, Northern Africa and the Mediterranean islands. Approximately two-thirds of currently recognised species are described based on their shell morphology, which may vary within due to biotic abiotic factors. Recent molecular phylogenies that included numerous previously documented populations recovered 14 clades, nine correspond nominal five, undescribed taxa. Here, we formally describe five taxa...
Several Pseudamnicola (Corrosella) populations of the central and eastern Iberian Peninsula have been ascribed to P. (C.) astieri (Dupuy, 1851), though recent evidence demonstrates species could be endemic departments Var Alpes-Maritimes in France. Through identification cryptic using a combined morphological phylogenetic approach, this paper provides detailed description astieri, clarifying its taxonomic boundaries confirming it as French endemic. In parallel, by comparing from provinces...
Molecular phylogenies of extant species are considered effective tools to infer mechanisms speciation. Here, we benefit from this utility investigate the evolutionary history an organismal group linked different aquatic ecosystems, microgastropod genus Pseudamnicola (family Hydrobiidae). Previous studies have found around 45 nominal subgenus P. (Pseudamnicola) , most them in coastal stream localities several Mediterranean islands and mainland territories, whereas only 12 other subgenus,...
Abstract Efforts to describe spatial patterns of freshwater diversity and evaluate their underlying factors have traditionally been focused on some animal groups (e.g. amphibians, fish or dragonflies). Despite being a dominant component in continental aquatic ecosystems crucial for determining priority areas conservation, broad‐scale data gastropod total species, endemic threatened species richness are limited. Based these biodiversity indices, we identify global hotspots, extinction risk...
The genus Pseudamnicola comprises a group of tiny springsnails inhabiting several continental and insular regions the Mediterranean basin. Given limited dispersal capabilities these animals, it is difficult to explain wide distribution range and, more specifically, its presence in isolated habitats, such as on islands. Thus, investigate process(es) that may patterns, we morphologically re-described genetically analysed six (Pseudamnicola) species occurring Iberian Peninsula nearby Balearic...
Abstract The metamorphosis of the glochidium critically endangered Margaritifera auricularia in gills a host is studied here for first time. Siberian sturgeon, Acipenser baeri, were infected with glochidia and regularly inspected using scanning optical microscopy. mature immediately attach to epithelium sturgeon gill filaments, piercing secondary lamellae connective tissues, blood cells, vessels within lamellae. Once pierced, overlapping cover form cyst. Metamorphosis takes place inside...
The glochidium of Margaritifera auricularia is described for the first time by using light microscopy, scanning electron microscopy and histological techniques. larval mantle formed only two layers cells; inner one being much thicker, with microvilli. All cell masses are temporary aggregations that rudiments organs subsequent juveniles which will be released after metamorphosis in host tissues. In there three main cells: (i) muscle, an anterior position; (ii) oral plate centre larva; (iii)...
A deep systematic study of the Spanish hydrobiid fauna is unravelling a more complex group species than was previously described. The use different taxonomical and statistical methodologies helps to clarify this old classification. Based on anatomical studies made for first time specimens from type locality Paludina sturmi (Rosenhauer, 1856), redescribed transferred new genus Boetersiella. demonstrates that Horatia (?) (sensu Boeters, 1988) combination two belonging new, but closely related...
El estudio de los moluscos agua dulce llevado a cabo en la Comunidad Madrid permite citar 33 especies, ellas 25 son gasterópodos y ocho bivalvos.De estas 23 ya habían sido citadas previamente esta área, aunque mayoría con otros nombres, bien porque actualidad sinónimos, o por determinaciones erróneas.Para las identificadas un total 463 muestras analizadas, junto el ejemplares conservados
Two new species of valvatoid hydrobiids are reported from southern and eastern Spain that showed notable similarities with Horatia Bourguignat, 1887 J. R. 1887.

The reproductive season of the relict species Margaritifera auricularia and three other freshwater mussels was studied by collecting their parasitic glochidial larvae with drift nets from 1997-1998. Drift net sampling indicated M. release glochidia during March April.

Most valvatiform genera of the gastropod family Hydrobiidae are narrow-range taxa. One exception is genus Arganiella, which comprised three congeners: type species A. pescei from Apennine Peninsula, wolfi Iberian Peninsula and tabanensis Balkans. The assignment latter two was based on morphological similarities with in shell, operculum, radula genitalia. Given that morphology hydrobiids sometimes susceptible to convergence, this study re-evaluates taxonomic status Arganiella by analysing...
