    Abstract Soil arthropod diversity contributes to a high proportion of the total biodiversity on Earth. However, most soil arthropods are still undescribed, hindering our understanding of soil functioning and global biodiversity estimations. Inventorying soil arthropods using conventional taxonomical approaches is particularly difficult and costly due to the great species richness, abundance and local-scale heterogeneity of mesofauna communities and the poor taxonomic background knowledge of most lineages. To alleviate this situation, we have designed and implemented a molecular barcoding framework adapted to soil fauna. This pipeline includes different steps, starting with a morphology-based selection of specimens which are imaged. Then, DNA is extracted non-destructively. Both images and voucher specimens are used to assign a taxonomic identification, based on morphology that is further checked for consistency with molecular information. Using this procedure, we studied 239 specimens of mites from the Canary Islands including representatives of Mesostigmata, Sarcoptiformes and Trombidiformes, of which we recovered barcode sequences for 168 specimens that were morphologically identified to 49 species, with nine specimens that could only be identified at the genus or family levels. Multiple species delimitation analyses were run to compare molecular delimitations with morphological identifications, including ASAP, mlPTP, BINs and 3% and 8% genetic distance thresholds. Additionally, a species-level search was carried out at the Biodiversity Databank of the Canary Islands (BIOTA) to evaluate the number of species in our dataset that were not previously recorded in the archipelago. In parallel, a sequence-level search of our sequences was performed against BOLD Systems. Our results reveal that multiple morphologically identified species correspond to different molecular lineages, which points to significant levels of unknown cryptic diversity within the archipelago. In addition, we evidenced that multiple species in our ...

    Abstract Description of a new species of Uroseius Berlese based on deutonymph and female specimens from northern Spain is presented. Observations of some cuticular organs on idiosoma and legs are described for the first time for the genus. An attempt to notate idiosomal setae as in Gamasina mesostigmatid mites is made based on complete dorsal chaetome of larval and pronymphal instars of Uroseius and Apionoseius Berlese species. Uroseius acuminatus (C.L. Koch) is a new record for the Iberian Peninsula. General morphological and biological aspects of Uroseius are presented. A tentative key, provided for separation of the 15 deutonymphs and nine adult females of the world species of Uroseius, is given.

    Abstract The genus Leioseius Berlese is reviewed, faunistically in North America, and taxonomically, world-wide. Descriptions of two new species, redescriptions of two previously recorded species, and first records of Leioseius elongatus Evans in North America are presented. Observations indicate that various leg setal and pretarsal attributes are useful in taxonomic discrimination of species in this genus. A key to North American species based on both idiosomatic and leg setal aspects is presented. Four species previously described under the genus Iphidozercon Berlese are accounted for the first time as species of Leioseius, and other taxa described previously as four yet other species of Leioseius are transferred to other genera. A tentative key, provided for separation of females of the 22 recognizable world Leioseius species, accounts for these changes. General morphological notes about mites of this genus are presented, some of which may lead to recognition of species-groups. Scant, general biological aspects about Leioseius mites are presented.

    Abstract Abstract Because of its ability to expedite specimen identification and species delineation, the barcode index number (BIN) system presents a powerful tool to characterize hyperdiverse invertebrate groups such as the Acari (mites). However, the congruence between BINs and morphologically recognized species has seen limited testing in this taxon. We therefore apply this method towards the development of a barcode reference library for soil, poultry litter, and nest dwelling mites in the Western Palearctic. Through analysis of over 600 specimens, we provide DNA barcode coverage for 35 described species and 70 molecular taxonomic units (BINs). Nearly 80% of the species were accurately identified through this method, but just 60% perfectly matched (1:1) with BINs. High intraspecific divergences were found in 34% of the species examined and likely reflect cryptic diversity, highlighting the need for revision in these taxa. These findings provide a valuable resource for integrative pest management, but also highlight the importance of integrating morphological and molecular methods for fine-scale taxonomic resolution in poorly-known invertebrate lineages.
