Three new species of the genus Coecobrya are described from caves in the Thai Peninsula for the first time: C. cavicta sp. nov. and C. polychaeta sp. nov. from Satun Province, and C. chumphonensis sp. nov. from Chumphon Province. These species differ in antennal length, clypeal chaetae, labial palp, sublobal chaetae of maxillary outer lobe, labial and postlabial chaetae, claw, ventral tube, manubrial plaque, and dorsal cephalic and tergal chaetotaxy. They are similar to C. annulata Zhang, Bedos & Deharveng, 2016 but differ from the latter in the combination of antennal length, claw and dorsal chaetotaxy. DNA barcoding COI sequences are provided for two species and three populations and key to the Thai species is also given. One population, which exhibits a great genetic distance (0.219–0.239) and minor but stable morphological differences from C. polychaeta sp. nov., cannot be accepted as a full species as the evidence is insufficient.

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.

Four new species of the chordeumatidan millipede genus Nepalella Shear, 1979, family Megalotylidae, are described from caves in southern China: N. troglodytes sp. nov., N. lobata sp. nov., N. jinfoshan sp. nov., and N. wangi sp. nov. Three of them (except N. lobata sp. nov.) are presumed troglobites. Additional locality records of two cave congeners, N. caeca Shear, 1999 and N. grandoides Golovatch, Geoffroy & Mauriès, 2006, are also provided. DNA-barcoding based on the COI mitochondrial gene is documented in this genus and for species of the order Chordeumatida outside Europe for the first time. Interspecific p-distances between Nepalella species amount to 8.5–15.9%, while intraspecific p-distances are 0–6.8%. The species of Nepalella are found to show a surprisingly low genetic distance from the European genus Atractosoma Fanzago, 1876, family Craspedosomatidae Gray in Jones, 1843, potentially based on the very limited number of barcoding sequences of the order Chordeumatida being available.

Chironomus sokolovae Istomina, Kiknadze et Siirin, 1999 (Diptera, Chironomidae) is recorded from Mongolia for the first time. Eleven banding sequences determined in the Mongolian population were previously known from Altai and Yenisei populations: sokA1, sokB1, sokB2, sokC1, sokC2, sokD1, sokD2, sokE1, sokF1, sokF2 and sokG1. The additional B-chromosomes are absent. DNA-barcoding of COI gene was carried out for this species for the first time. The phylogenetic tree estimated by Bayesian inference showed a high similarity of the studied species with Ch. acutiventris Wülker, Ryser et Scholl, 1983 from the Chironomus obtusidens-group. The estimated genetic distance K2P between Ch. sokolovae and Ch. acutiventris is much lower (0.38%) than the commonly accepted threshold of 3% for species of genus Chironomus Meigen, 1803. Our results show that the accepted cytogenetic criteria of species level in the genus Chironomus are more in accordance with morphological ones of the same level, than with molecular-genetic criteria accepted for species COI genetic distance.

The genus Olepa is distributed in Palearctic and Oriental regions with more species in India and Sri Lanka. In the recent studies, morphological variations within the group were well established, with couple of first set of mt COI DNA barcodes for at least three species. In the present account, three new species and a new subspecies are described from the northern Western Ghats region of Maharashtra based on mt COI DNA barcode studies. Due to high morphological divergence and complete genetic homogeneity on the mt COI DNA, four morphotypes under two species are reported. Morphological and genital characters of male and female are provided along with their respective species morphotypes for the first time under this genus from India. The genitalia and the habitus of male and female are illustrated. Preliminary phylogenetic tree based on the mt COI DNA sequences available in the GenBank for the genus with the sequences for the new species also provided and discussed. Key words: new taxa, morphotype, Maharashtra, DNA barcoding, mt COI gene

The Swedish species of Enicospilus are reviewed. Three species are described from Swedish material; Enicospilus cederbergi sp. nov., Enicospilus intermedius sp. nov. and Enicospilus ryrholmi sp. nov. Four species: Enicospilus cerebrator Aubert, 1966, Enicospilus combustus (Gravenhorst, 1829), Enicospilus merdarius (Gravenhorst, 1829) and Enicospilus myricae Broad & Shaw, 2016, are reported from Sweden for the first time. An illustrated key to the Swedish species of Enicospilus is provided. Validity of the new species is supported by DNA barcoding.

Material collected between 2000 and 2014 on the island Borneo, including the Indonesian province of Kalimantan, the Malaysian province of Sabah and Brunei Darussalam, substantially increased our knowledge of Labiobaetis on this island. The total number of Labiobaetis species in Borneo increased to five, as only one species, L. borneoensis (Müller-Liebenau, 1984), was previously reported. Three new species were identified by morphology and partly by using genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae (Labiobaetis bakerae sp. nov., L. penan sp. nov. and L. dayakorum sp. nov.); in one case, the imago is described as well. New reports of L. borneoensis are presented and the imago of this species is described for the first time. Labiobaetis moriharai (Müller-Liebenau, 1984), originally described from mainland Malaysia (Province Selangor), is reported from Borneo for the first time. The interspecific K2P distances in Borneo are between 19% and 25%, the intraspecific distances are usually between 0% and 1%. The total number of Labiobaetis species worldwide is augmented to 126.

Euastrum lacustre is reported for Russia for the first time. This alcaliphilic species was found in the periphyton and plankton of three lakes in the Kursk Region (European Russia). A description of morphology, including the relief of cell wall, and habitats where this taxon is found are represented. LM and SEM microphotographs are provided. Morphological differences of E. lacustre from similar species are discussed. New species for region, namely Closterium aciculare, Cosmarium formosulum, C. granatum, C. pseudoinsigne, C. reniforme and Staurastrum pingue, are found in the samples together with E. lacustre.
