Water mite species of the genus Mideopsis Neuman, 1880 are common in running and standing waters in the Palaearctic. In the present study we used an integrative taxonomic approach by applying partial COI sequences (DNA-barcodes) and morphological characteristics to describe a new species, Mideopsis milankovici sp. nov. from the Mediterranean region of Montenegro. A high genetic distance (18.8-26% K2P) from three other known European congeners, M. crassipes Soar, 1904, M. orbicularis (Müller, 1776), and M. roztoczensis Biesiadka and Kowalik, 1979, support M. milankovici sp. nov. as a distinct species. From M. persicus Pešić and Saboori, 2015, a species known from South Iran, which resembles the new species in the shape of the ejaculatory complex, M. milankovici sp. nov. differs by the morphology of dorsal shield.

A New Species

A new species of water mites from Montenegro and Bulgaria, Atractides anae Pešić sp. nov., is described, combining traditional morphological techniques with the analysis of partial mtDNA COI sequences (DNA-barcodes). Based on our molecular and morphological analysis, the new species is most closely related to the crenobiontic A. pennatus (K. Viets 1920) from which it differs by 6.4 (SD = 1.12)% K2P distance. A dataset including the novel COI sequences of 10 Atractides species from Montenegro and Iran is assembled in order to facilitate further studies on the genus by using molecular tools.

Morphological And Molecular Data

Seven new species of Dactylogyrus Diesing, 1850 (Dactylogyridae) are described from the gills of seven endemic species of cyprinoids (Cyprinidae, Leuciscidae) inhabiting the Balkan Peninsula: Dactylogyrus romuli n. sp. from Luciobarbus albanicus (Greece), Dactylogyrus remi n. sp. from Luciobarbus graecus (Greece), Dactylogyrus recisus n. sp. from Pachychilon macedonicum (Greece), Dactylogyrus octopus n. sp. from Tropidophoxinellus spartiaticus (Greece), Dactylogyrus vukicae n. sp. from Delminichthys adspersus (Bosnia and Herzegovina), Dactylogyrus leptus n. sp. from Chondrostoma knerii (Bosnia and Herzegovina), and Dactylogyrus sandai n. sp. from Telestes karsticus (Croatia). To delineate species boundaries, we used an integrative taxonomic approach combining morphological and genetic data. With these tools, we illustrate that some species of monogeneans considered as cryptic might be designated as pseudocryptic (morphologically similar, not easily differentiated) after a posteriori detailed morphological examination, as happened with D. romuli n. sp. and D. remi n. sp. Thus, for accurate species characterization, it is particularly important to acquire both morphological and molecular data from the same individual specimens, ideally along with illustrations of taxonomically important structures directly taken from hologenophores. Using phylogenetic reconstruction, we investigated the phylogenetic position of newly described Dactylogyrus species within Dactylogyrus species from Balkan cyprinoids with regard to morphological characteristics, host range, and geographical distribution.

Morphological And Molecular Data

An investigation of the taxonomic status of Pareas hamptoni (Hampton's Slug snake) based on morphological and molecular data revealed a new distinct species from the Golden Triangle region (comprising parts of southern China, and adjacent Laos and Thailand). The new species is shown to be a sister species to P. hamptoni but can be separated from the latter by having 3–5 dorsal scale rows at midbody slightly keeled (vs 5–9 scales strongly keeled); a lower number of ventrals, 170–188 (vs 185–195); and a lower number of subcaudals, 67–91 (vs 91–99). The new species is currently known from northwestern Thailand, northern Laos, and the southern part of Yunnan Province in China at elevations of 1,160–2,280 m a.s.l. We suggest that the new species to be considered of Least Concern (LC) in the IUCN‘s Red List categories. Problems of taxonomy and actual distribution of the P. hamptoni complex are briefly discussed; our results show P. hamptoni is now reliably known only from Myanmar and Vietnam, but its occurrence in Yunnan Province of China is likely.

In this paper, a new spider species of the genus Loxosceles is described on the basis of morphological and molecular data. The phylogenetic relationship of the new species is discussed through the lens of molecular data (cox1, rrnL and H3 genes). Specimens were collected from three Iranian caves in the provinces of Fars, Yazd and Khuzestan, and the specimens showed morphological characteristics that allowed us to easily distinguish Loxosceles persica n. sp. from L. mrazig, which is its sister species, and from the cosmopolitan L. rufescens, which is a widely distributed species throughout the Mediterranean basin and the Middle East. It is the first Loxosceles species endemic to the Middle East.

Morphological And Molecular Data

The gekkonid lizard genusHemidactylusOken is the second most species-rich genus of geckos with greatest diversity in the tropical regions of the world. Some species of the genus are commensal and widespread; however, there are several endemic lineages with restricted distribution. India is home to at least 35 species, with 20 endemic species and the number is steadily increasing with exploration of new habitats and integrated taxonomic approach including molecular data. We made investigations into the molecular and morphological variation throughout the distribution ofHemidactylus triedrusDaudin, 1802 based on fresh specimens, literature review, museum material and molecular data. Results from morphological, molecular and micro-CT based anatomical data are unequivocal and show thatH. triedrusis a species complex represented by three species,H. triedrussensu stricto and two undescribed taxa.H. subtriedrusJerdon, 1854 syn. nov. was found to be morphologically similar to the type specimen ofH. triedrus, and genetically embedded in a clade containingH. triedrussensu stricto and is here treated as a junior synonym ofH. triedrus, whereasH. lankaeDeraniyagala is referred to asnomen dubiumgiven that the types are presently not traceable and the original description is inadequate in diagnosing the taxon. The populations from western-central India and parts of Pakistan, and from southern Karnataka are distinct and diagnosable, and are herein described as two new species, respectively. Morphological and molecular data support the distinctiveness of the new species. The present work resolves a taxonomic turmoil that lasted over two centuries highlighting the need for studies that integrate morphological and molecular data.

Combining morphological and molecular data in an integrative approach, three new mayfly species of Epeorus (Caucasiron) are described. These include Epeorus (Caucasiron) alborzicus Hrivniak & Sroka, sp. nov. and Epeorus (Caucasiron) shargi Hrivniak & Sroka, sp. nov. from northern Iran, and Epeorus (Caucasiron) zagrosicus Hrivniak & Sroka, sp. nov. from central Iran. They are unambiguously delimited using both distance-based and likelihood-based approaches in the analyses of barcode COI sequences. Each new species is compared with other species of the subgenus and morphological diagnostic characters are provided. Based on extensive sampling of streams throughout the country, the distribution and habitat preferences of all Caucasiron species in Iran are assessed. Altogether, there are now six species recorded, among them also E. (C.) nigripilosus Sinitshenkova, 1976 is reported for the first time in Iran. Five species are distributed in the Alborz Mts. in northern Iran, one species was found in the Zagros Mts. in central Iran.

Crangonyx ephemerus n. sp. and Crangonyx pseudoephemerus n. sp. are described from the headwaters of the St. Marks River in Leon County, Florida, based on detailed morphological and molecular comparisons with the closely related species Crangonyx floridanus Bousfield, 1963. The morphological and molecular data, including three species delimitation models, lend support to the hypothesis that the taxon C. floridanus sensu lato represents a species complex. Diagnostic morphological characteristics are highlighted and discussed within this group to assist in future morphological analyses.

Mite Genus

The water mite genus Wettina has a Holarctic distribution and includes only one known species from the Palaearctic, i.e. W. podagrica (Koch, 1837). This species has been considered as a rhitrobiontic and crenophilous species. In the present study we used morphological data and DNA barcoding to describe a new species of the genus, W. lacustris sp. nov. from the glacial Biogradsko Lake in northern Montenegro. The level of COI differentiation between lake population of Wettina lacustris sp. nov. and stream and spring populations of W. podagrica from Western Europe (The Netherlands) was 8.4%. It is likely that Wettina lacustris sp. nov. is more widely distributed in the Palaearctic.

A new species of aeglid crab, Aegla okora n. sp., is described. This species was found in the Iguaçu River basin in Paraná state, southern Brazil. Aegla okora n. sp. was discriminated based on morphological and molecular data (mitochondrial COI). Morphologically, the new species differs from congeners of the same river basin by the presence of a trapezoidal areola and the ventromesial border of the ischium having three tubercles, besides other exclusive additional morphological characteristics. Molecular results demonstrated that there is no overlap between the intraspecific distances of Aegla okora n. sp. and the interspecific distance of other species of Aegla added to the analysis, confirming the separation of species and increasing the known diversity of the Iguaçu River basin.
