First record of Pemphigus saliciradicis (Börner, 1950) (Hemiptera: Aphididae) on roots of the grape vine, Vitis vinifera (Vitaceae) from Transcaucasia

Apterous and alate viviparous females of the aphid Pemphigus saliciradicis (Börner, 1950) collected for the first time on roots of the grape vine (Vitis vinifera, Vitaceae) near Tbilisi (Georgia) in 1968 are redescribed and illustrated. A key to the alatae of the genus Pemphigus Hartig species distributed in Transcaucasia is given

Description of a new species of the genus Macrosiphum Passerini, 1860 (Hemiptera: Aphidoidea: Aphididae), with a key to the Macrosiphum species occurring in Transcaucasia

Apterous viviparous females of Macrosiphum dzhibladzeae Barjadze sp. n. living on Euphorbia macroceras (Euphorbiaceae) are described and illustrated. A key to the apterous viviparous females of Macrosiphum species living on Euphorbia spp. worldwide is given. A previous key for the apterous viviparous females of the Macrosiphum species recorded from Transcaucasia is provided, modified to include the new species

Is Rhus-living Eriosomatinae aphid in Turkey really a new species?

Seven alate females collected on Rhus sp. by Dr. Murat Aslan in Turkey are re-studied. Originally considered as an undescribed species, the specimens are determined as Baizongia pistaciae (L.). Misidentification of the host plant probably contributed to lead on the initial confusion. Morphological measurements and ratios of diagnostic characters for the alatae are provided

Two new species of the aphid genus Uroleucon (Hemiptera: Aphididae) living on Grindelia in the USA

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

Checklist of Georgian centipedes (Myriapoda: Chilopoda)

Abstract The Caucasus ecoregion is distinguished by its biodiversity. The flora and fauna of the ecoregion became the study area of many zoologists and botanists. Georgia, as a part of it, is important for its valuable and impressive diversity. However, despite many years of scientific research, certain groups, among them centipedes, are not so well studied. This is the first comprehensive summary of current knowledge about centipedes distributed in the territory of Georgia, based on literature data. It provides information about 59 taxa (57 species and two subspecies) known from Georgia, belonging to 16 genera in seven families from four orders. Nineteen species are endemic to the Caucasus, eight of which are Georgian endemics. Among them, two species: Cryptops datviensis Tuf, Barjadze, and Maghradze, 2022, and Harpolithobius birsteini Zalesskaja, 1972, are troglobiotic. Another four species (Lithobius caucasicus Sseliwanoff, 1881; Lamyctes coeculus (Brölemann, 1889); Lithobius semperi (Haase, 1887); and Scolopocryptops nigridus McNeill, 1887) are considered doubtful records. An overview of local and global distribution for each taxon is included. Lithobius fasciatus Muralevitch, 1929, syn. nov. is formally synonymized with Lithobius striatus Muralevitch, 1926

An annotated list of the Georgian harvestmen (Arachnida, Opiliones)

Abstract An annotated list of the Georgian harvestmen was prepared based on literature and unpublished collection data, in which 48 species belonging to 19 genera within six families are included. Twenty-seven species are endemic to the Caucasus Ecoregion, while 10 species are endemic to Georgia. Five species are highly specialized cavernicolous ones and are only known from caves. Former subspecies Nemastoma suberbum bacuriana Mkheidze, 1959, is ranked as an independent species, Paranemastoma bacurianum (Mkheidze, 1959) (comb. nov. et stat. nov.); Metaplatybunus hypanicus Šilhavý, 1966, is justified as a junior synonym of Metaplatybunus georgicus Mkheidze, 1952 (syn. nov.)

Review of the genus Cryptophagus Herbst, 1863 (Coleoptera Cryptophagidae) from Georgia.

Cryptophagus axillaris Reitter, 1875 from Savekuo Cave is recorded for the beetle fauna of the Caucasus for the first time, while C. lycoperdi (Scopoli, 1763) from Bichvinta (=Pitsunda) is a new record for Georgian beetle fauna. Twenty five species of the Cryptophagus beetles are recorded in Georgia. Sampling data and distribution map for the genus Cryptophagus species are given. Identification key to the genus Cryptophagus in Georgia is provided

A new Diplura species from Georgia caves, Plusiocampa (Plusiocampa) imereti (Diplura, Campodeidae), with morphological and molecular data

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
