Two species of leeches were described from Georgia in the past, Dina ratschaensis Kobakhidze, 1958 from the Racha-Lechkhumi and Kvemo Svaneti region and Trocheta ariescornuta Grosser, Barjadze & Maghradze, 2021 from the Samegrelo-Zemo Svaneti region. Both species were the only known typical representatives of cave leeches in Georgia. Recently, two more species of the genus Dina R. Blanchard, 1894 have been found in karst caves in this country. These leeches are morphologically similar to D. ratschaensis, from which they differ in the shape of the reproductive system, primarily the shape of the cornua of the genital atrium and the shape and extension of the vasa deferentia and ovisacs, justifying the description of two new species, Dina imeretiensis Grosser, Barjadze & Maghradze sp. nov. from the Imereti region and Dina samegreloensis Grosser, Barjadze & Shavadze sp. nov. from the Samegrelo-Zemo Svaneti region. Data on the cave dwelling invertebrate communities in the studied caves are provided. Molecular data are provided, and a phylogenetic tree based on Cox1 sequences of Dina spp. and related genera is provided and discussed.
The present paper is devoted to the description of three new species of the genus Acanthophorella Antić & Makarov, 2016 from Georgia, western Caucasus: A. devi Antić sp. nov. and A. valerii Antić sp. nov., both presumed troglobionts and each from a single cave, and the epigean A. aurita Antić sp. nov. The troglobiotic Acanthophorella barjadzei Antić & Makarov, 2016 is reported from two additional caves, with further descriptive notes given. Notes on the ecology and localities, and a distribution map for all six species of the genus are presented. A key is given to all members of the Flagellophorella complex. The relationships within the complex and the distribution and troglomorphism in the genus Acanthophorella are briefly discussed.
A new dipluran species, Plusiocampa (Plusiocampa) imereti Sendra & Barjadze sp. nov., from the deep zone in three caves in the Imereti region, Georgia, is described. This new troglobitic Plusiocampa is an addition to four others known Diplura from around the Black Sea region, two Dydimocampa and two Plusiocampa s. str. The present study also provides the first CO1 sequences for the Plusiocampinae taxa and the first molecular data for cave-dwelling Plusiocampa species. Although bootstrap values were low, the maximum-likelihood phylogenetic tree grouped Plusiocampa (P.) imereti Sendra & Barjadze sp. nov. with two Plusiocampa s. str. species from Eastern Europe. Morphologically, P. (P.) imereti Sendra & Barjadze sp. nov. is closely related to two cave-dwelling species: Plusiocampa (Plusiocampa) glabra Condé, 1984 and Plusiocampa (P.) chiosensis Sendra & Gasparo, 2020. The new species can be distinguished by the presence of lateral anterior macrosetae on metanotum, more uneven claws, and the presence of 2+2 lateral anterior macrosetae on middle urotergites. The five species currently known for the Black Sea region inhabit caves located at low altitude but with no influence from former glacial or permafrost processes.
Specimens of Deuteraphorura collected in 11 Georgian caves were analysed morphologically and molecularly based on the COI gene barcode region. Two molecular delimitation methods revealed four species (MOTUs); however, only two of them were distinguished morphologically and are described in this paper as new to science. Both new species, D. colchisi sp. nov. and D. kozmani sp. nov., belong to the group with a pseudocellus on the first thoracic tergum; the differential diagnosis table to this species group is provided. The potential of the Caucasus as a hotspot region of subterranean biodiversity and evolution centre of subterranean animals is discussed.
Two new species of the aphid genus Uroleucon (Hemiptera: Aphididae) living on Grindelia in the USA
(2020)
Here, we present descriptions of two new aphid species of the genus Uroleucon Mordvilko, 1914 (Hemiptera: Aphididae: Macrosiphini), which are associated with the plant genus Grindelia Willd. (Asteraceae). An apterous viviparous female of Uroleucon (Lambersius) robinsoni sp. nov. from Oregon and apterous and alate viviparous females of Uroleucon (Lambersius) grindeliae sp. nov. from Colorado are described and illustrated. Taxonomical notes of the new and other Grindelia-feeding taxa of Uroleucon are given and an updated key to the apterae of the Grindelia-feeding species of Uroleucon in the world is provided.
