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

<em>Panonychus</em> from Georgia: survey, taxonomical status and redescription of <em>P. hadzhibejliae</em> (Reck, 1947) (Acari, Tetranychidae)

International audienceA survey of Panonychus species was undertaken across Georgia from 2005 to 2014 on various host plants, revealing three species: Panonychus citri (McGregor, 1916), Panonychus hadzhibejliae (Reck, 1947) and Panonychus ulmi (Koch, 1836). New hosts for P. ulmi and P. citri are recorded, Buxus sempervirens, Hedera colchica and Prunus laurocerasus for P. ulmi and Ficus carica for P. citri, whereas P. hadzhibejliae was only found on F. carica. The newly collected material also allowed us to investigate the taxonomical status of P. hadzhibejliae. The comparison of P. hadzhibejliae with the two closely related species sampled in the survey, P. ulmi and P. citri, and with data of P. caricae found in the literature, shows that P. hadzhibejliae is a valid species. It can be separated from the three other Panonychus species without ambiguity especially using the female dorsal setae length in combination with the ratio between the length of the female dorsal opisthosomal f(2) and h 1 setae and the ratio between the palptarsal terminal eupathidium su and the related solenidion.. A redescription of P. hadzhibejliae is provided including the male and some morphological characters, measurements and drawings of the female that were omitted in the original description. A key to the world species of Panonychus is also proposed

Soil mite (Acari: Oribatida) communities in the limestone quarry of Saskhori (Gerogia)

Abstract The present publication provides a review of the soil mite (Acari; Oribatida) community’s structure and the connection between changes in environmental factors and oribatid mite diversity in the limestone quarry of Saskhori and its adjacent areas. Overall, 52 species were recorded during the study. The most abundant oribatid mite species were Steganacarus carinatus, Aleurodamaeus setosus, Xenillus tegeocranus, Ceratoppia bipilis, Oribatula tibialis, and Punctoribates punctum. Interestingly, 23 species of oribatid mites were recorded for the first time from the limestone quarry of Saskhori, and one species (Liacarus oribatelloides) was a new record for the Caucasus fauna. The following indices were analyzed: abundance (N), species diversity (S), Shannon’s diversity index (H), and Pielou’s evenness index (J’). Regarding the obtained results, the highest density of oribatid mites was recorded in the habitat with Shibliak shrubbery (332 inds/m2), while the forest habitat was characterized with the highest value for Shannon’s diversity index (2,64). In the publication, we also provide a detailed morphological description of the newly recorded species L. oribatelloides, with the respective illustration, as no figures are given in its original description

Revision of the genus Pseudobryobia McGregor, 1950 (Acari, Tetranychidae)

International audienceThe species of the tetranychid mite genus Pseudobryobia are revised mainly based on data published in the literature. Following a survey of the classification history of the genus, emphasizing the changes that occurred in the morphological characters used in its definition, we briefly discuss their relative importance for the genus delimitation. As a result, we provide amended diagnoses for the genera Pseudobryobia and Bryobia and transfer 7 species from Pseudobryobia to Bryobia. Species belonging to the genus Pseudobryobia bear two setae on coxisternal plate II, one pair of tenent hairs on all the empodia and are distributed in the Nearctic biogeographic zone. Conversely, some species previously assigned to the genus Pseudobryobia bear one seta on coxisternal plate II, two rows of tenent hairs on empodia II-IV, and are recorded in the Palearctic and Afrotropical biogeographic zones. These species are transferred to the genus Bryobia. The following nomenclature changes resulting from the revision are proposed: B. (Bryobiopsis) abbatielloi new combination, B. (B.) anacantha reinstated combination, B. (Allobia) bucharica reinstated combination, B. (B.) eurotiae reinstated combination, B. (A.) japonica reinstated combination, B. (B.) neoephedrae new combination, B. (A.) nikitensis reinstated combination. We recognise six subgenera for Bryobia, as previously considered by other authors, and also treat Nuciforaella Vacante (1983) as a junior synonym of Bryobia (Allobia) Livshits and Mitrofanov, 1971. A key to the species of Pseudobryobia is also provided
