Apterous viviparous females of Aphidura jimoi sp. nov. living on Dianthus in East Georgia, are described and differences with the most similar species genus—A. naimanica Kadyrbekov, 2013, presented. Additional data provided for apterous A. pakistanensis Nieto Nafría, Mier Durante & Remaudière, based first record from Georgia hitherto unknown alate this described. Updated identification keys all currently included genus Aphidura, those feeding specifically spp. provided.
During a biospeleological survey of caves Imereti region (Georgia), new species the beetle genus Bergrothia Reitter, B. barbakadzei sp. nov. was discovered in three caves: Datvis (Bear), Prometheus and Melouri (Sataplia–Tskaltubo karst massif, Tskaltubo district). The is described, illustrated differentiated from other morphologically similar genus—B. mingrelica (Reitter). first cavernicolous Bergrothia. A key to this provided.

The very similar to kelasuricus the Tsebelda karst massif formation in Apkhazeti, Georgia, but differ having two inner spine-like chaetae on edge hind tibiotarsus (only one kelasuricus) occupying different, isolated cave formations separated by a geographic distance nearly 100 km. A key Plutomurus with 6...
Here, we present descriptions of two new aphid species the genus Uroleucon Mordvilko, 1914 (Hemiptera: Aphididae: Macrosiphini), which are associated with plant Grindelia Willd. (Asteraceae). An apterous viviparous female (Lambersius) robinsoni sp. nov. from Oregon and alate females grindeliae Colorado described illustrated. Taxonomical notes other Grindelia-feeding taxa given an updated key to apterae in world is provided.
Two highly specialized endemic troglobiotic harvestman species of the genus Nemaspela Šilhavý, 1966 are described. N. melouri sp. nov. from Melouri Cave and prometheus Prometheus (Sataplia-Tskaltubo karst massif, Imereti region, western Georgia), respectively. Despite fact that entrances caves positioned only 2.5 km apart, new taxa differ each other distinctly by presence vs. absence male cheliceral apophysis, which is lacking in second species. A key to Caucasian provided. Relationships...
A new dipluran species, Plusiocampa (Plusiocampa) imereti Sendra & Barjadze sp. nov., from the deep zone in three caves Imereti region, Georgia, is described. This troglobitic an addition to four others known Diplura around Black Sea two Dydimocampa and s. str. The present study also provides first CO1 sequences for Plusiocampinae taxa molecular data cave-dwelling species. Although bootstrap values were low, maximum-likelihood phylogenetic tree grouped (P.) nov. with species Eastern...
In this paper, we present a review of stridulating species aphids the Macrosiphini genus Uroleucon (Hemiptera, Aphididae) and include 13 species. The most characteristic feature reviewed is presence unusual aphids’ peg-like sensilla distributed on hind tibia, which are rubbed against surface siphunculi. A new aphid species—Uroleucon remaudierei sp. nov., living Asyneuma persicum Michauxia laevigata (Campanulaceae) in Iran—is described illustrated based apterous alate viviparous females....
During investigations of the cave fauna in Georgia, two new taxa carabid beetles were discovered. Inotrechus usholtaensis sp. nov. from Usholta Cave and Duvalius gregoi Kvedi II Cave, Racha-Lechkhumi Kvemo Svaneti region, are described, illustrated, differentiated morphologically similar species. Identification keys to species genera Caucasus provided.
Here we present a description of new aphid species—Uroleucon (Uroleucon) lebanonense sp. nov. associated with Tragopogon coloratus (Asteraceae) in Lebanon. Apterous and alate viviparous females the species are described illustrated, compared morphologically similar Uroleucon (U.) mongolicum Holman, 1975. An identification key to Palaearctic three setae on first tarsal segment is provided. On basis re-examination type material, propose restore valid status U. altaicum Szelegiewicz, 1982 bona...
Plutomurus weinerae sp. nov. from Usholta Cave, Racha-Lechkhumi and Kvemo Svaneti region, Georgia, P. danialensis Danial Mazandaran province, Iran are described, illustrated differentiated other morphologically similar congeners. New species distinguishable by head abdominal macrochaetotaxy (P. weinerae) shorter antennae danialensis). An updated identification key to the of genus known Western Palearctic is presented. A list invertebrate communities for caves provided.
Eight aphid species - Aphis hederae Kaltenbach, 1843, A. mirifica (Börner, 1950), origani Passerini, 1860, umbrella Chaitophorus horii Takahashi, 1939, Hyadaphis coriandri (Das, 1918), Uroleucon jaceae (Linnaeus, 1758) and U. inulicola (Hille Ris Lambers, 1939) are recorded for the first time from Armenia. Additionally, newly Caucasian fauna. Sampling data, biology, distribution each provided. Key Words: Aphis, Chaitophorus, Hyadaphis, Uroleucon, Host plant, Caucasus
Information about the cave invertebrates of Georgia, Caucasus, is summarised, resulting in 43 troglo- and stygobiont taxa reported from 64 caves. Species distribution analyses were conducted for 61 caves harbouring 58 invertebrate taxa, with majority (39) located Apkhazeti (north-western Georgia). In 22 central-west Georgia (Samegrelo, Imereti Racha-Lechkhumi regions west Georgia) 31 are reported. Composition fauna differed strongly between Georgia. Only two total 86 shared, negligible...
Seven aphid species are recorded from the countries of Middle East and Caucasus for first time, which three new records Turkey, two Lebanon, one each Iran Georgia. New host plant genera reported Aphis cephalariae Barjadze, Anoecia vagans (Koch), Macrosiphum symphyti Barjadze Chakvetadze. Information on biology geographical distribution is also provided.
Two new species of the genus Plutomurus, P. revazi sp. nov. from Prometheus and Satsurblia caves eristoi Satevzia Cave are described, illustrated differentiated other morphologically closely related species. A high variability in number teeth claw, unguiculus mucro demonstrate that these characters not useful for diagnosis. However, dorsal chaetotaxy was shown to be stable character this purpose. Analysis DNA sequences COI 28S genes is congruent with species-level groups delimited by...

Three new species: oezdemirae Kanturski & Barjadze sp....
Faunal surveys were performed in Mtirala National Park (Georgia, Caucasus). Oribatid mites collected from four microhabitats (soil, moss, litter, decaying wood) at 15 locations 250 to 1000m a.s.l. Forest types included walnut (Juglans regia) plantations, mixed chestnut (Castanea sativa) forests, and beech (Fagus orientalis) forests. Our revealed 124 species of oribatid mites. One species, Feiderzetes latus (Schweizer, 1956), is new for Georgian fauna was found only wood various stages decay....
