Two nominal species of water frogs of the genus Pelophylax, P. ridibundus and P. bedriagae, are found in Central and Eastern Europe, the Middle East, Western Asia, Western Kazakhstan, and Siberia. So far, the taxonomic status of Pelophylax in most of the Caucasus has remained unknown. Sequencing of the Cytochrome Oxidase 1 mitochondrial gene attributed the frogs throughout Georgia to the P. ‘bedriagae’ lineage, bringing them very close to the specimens from Kazakhstan and Greece. Simultaneously, the current nomenclature of water frogs appears to be formally incorrect since western Kazakhstan, the type locality for P. ridibundus, has frogs genetically closer to nominal P. bedriagae, than to nominal P. ridibundus from Europe. Because there is no evidence that the frogs from Central Europe, Kazakhstan, and the Caucasus, as well as from Anatolia and Iran, are biological species with individual evolutionary pathways, we suggest a conservative approach and synonymize nominal P. bedriagae from most of West Asia with P. ridibundus.
Pelophylax属的两个标称物种P. ridibundus和P. bedriagae分布于中欧、东欧、中东、西亚、哈萨克斯坦西部和西伯利亚。迄今为止，Pelophylax 在高加索大部分地区的分类地位仍然未知。细胞色素氧化酶 1 线粒体基因的测序结果显示，格鲁吉亚的蛙类属于 "bedriagae "蛙系，与哈萨克斯坦和希腊的标本非常接近。同时，目前的水蛙命名法似乎在形式上是不正确的，因为哈萨克斯坦西部（P. ridibundus 的模式产地）的蛙类在基因上更接近于标称的 P. bedriagae，而不是欧洲标称的 P. ridibundus。由于没有证据表明中欧、哈萨克斯坦、高加索以及安纳托利亚和伊朗的蛙类是具有单独进化途径的生物物种，我们建议采取保守的方法，将西亚大部分地区的标称 P. bedriagae 与 P. ridibundus 同名。

The present study provides the length-weight relationships (LWRs) for four difficult-to-sample Caspian endemic gobies for the first time: Benthophilus persicus, Benthophilus baeri, Knipowitschia longecaudata, and Hyrcanogobius bergi. They were collected from shallow and deep waters of the southwestern Caspian Sea using various methods, including beach seining, scuba diving, and deepwater bottom beam trawls. The slope (b) of LWRs ranged from 2.874 for B. baeri, to 3.408 for H. bergi with coefficient of determination higher than 0.918. The b values showed significant differences between the sexes of all species.

The present study aims to provide an updated checklist of the owlfly subfamily Ascalaphidae Lefèbvre, 1842, with the first records of the genus Deleproctophylla Lefèbvre, 1842, from the country. The new records give an improved understanding of owlfly distribution within the country. The record of the genus Deleproctophylla in Georgia is based on a single female specimen of D. australis (Fabricius, 1787).

Abstract Visual inspection of several embryos of the parthenogenetic lizard Darevskia armeniaca revealed the presence of an embryo with axial bifurcation (“two-headed”) on the stage of pigmented eyes and plate-like limb buds with a distinct border at the edges. This is the third recorded case of axial bifurcation in D. armeniaca, although two previous cases were mentioned without further discussion. Here the bicephalic embryo is described in detail and the potential reasons are discussed. The analysis of the literature on axial bifurcation in lacertids suggests that this type of developmental disorder may be particularly common in this parthenogenetic form. Hybridization may cause multiple developmental disorders, including incomplete separation of twin embryos; all parthenogenetic Darevskia have a hybrid origin, and this may cause the disorders rather than parthenogenetic reproduction by itself. The hypothesis needs further study with more representative samples of parthenogenetic and sexually reproducing Darevskia.
摘要 对孤雌生殖蜥蜴 Darevskia armeniaca 的几个胚胎进行目测后发现，在有色素的眼睛和边缘有明显边界的板状肢芽阶段，有一个胚胎具有轴向分叉（"双头"）。这是 D. armeniaca 中第三个有记录的轴向分叉案例，之前的两个案例只字未提。这里详细描述了双头胚胎，并讨论了可能的原因。对有关漆虫轴向分叉的文献分析表明，这种类型的发育障碍在这种孤雌生殖形式中可能特别常见。杂交可能会导致多种发育障碍，包括孪生胚胎的不完全分离；所有孤雌生殖的大龙虾都有杂交起源，这可能是导致发育障碍的原因，而不是孤雌生殖本身。这一假说需要用更有代表性的孤雌生殖和有性生殖的大龙虾样本进行进一步研究。

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.
