| Аннотация: | The family Macronyssidae (Acari: Mesostigmata) comprises mostly obligate blood-sucking ectoparasites of bats (Mammalia: Chiroptera) and some other animals, such as small mammals, reptiles and birds. Hem, we document and curate previously known data, and, based on our extensive survey, provide this article of bat-associated macronyssid mites of the Russian Federation. We record a total of 24 mite species belonging to 4 genera (Ichoronyssus, Macronyssus, Steatonyssus, and Cryptonyssus). Twenty-seven new host-parasite associations are reported. In addition, were provide data on five major Russian regions, for which bat-associated mite records were lacking. | |

| Аннотация: | Background. Molecular typing by PCR-RFLP method allows to identify the spe-cific attribution of an organism that has a weak phenotypic difference. The main advantage of this research method is the capacity to analyze a large number of samples without apply-ing the sequencing method. The purpose of the work is to develop a test-system for the identification the matrilines of marsh frogs of the Pelophylax ridibundus complex from Kazakhstan. Materials and methods. The analysis was based on the variability of the prima-ry structure of the mitochondrial gene the second subunit of dehydrogenase (ND2) which is a species-specific marker. Subsequently a search for marker nucleotide substitutions speci-fic for each lineage and recognition sites for the HaeIII and TasI restriction endonucleases was conducted. Results. As a result of the research, it was confirmed that on the territory of Kazakhstan inhabiting three main forms of lake frogs where two of them are native (Balkhash, Syrdarya), and invasive Anatolian form - P. cf. bedriagae. Conclusions. The authorsʼ PCR-RLFP test technique is a straightforward and reliable tool for detecting mitochondrial lineages in the Pelophylax ridibundus complex marsh frogs and may be used successfully in mass screening investigations. | |

| Аннотация: | Here we present the first new data about the mysterious "anomaly P" of green frogs (genus Pelophylax) in about 50 years. We established that the gastropod Planorbarius corneus could be an intermediate host (or vector) of the infectious agent of the anomaly P. Symmetrical cases of polydactyly, the anomaly "cross" and heavy cases of the anomaly P, which were previously found in natural populations in the European part of Russia and recently obtained in laboratory, can be caused by this infectious agent. As the most probable cause, we assume a species of trematodes, for which the first intermediate host is P. corneus, from which they infest tadpoles of green frogs. | |

| Аннотация: | Based on a combination of molecular and morphological data, we herein report a new species within the bufonid Bufo gargarizans species complex. This is a widespread species complex with distribution from eastern Russia and the Korean Peninsula to China and the Ryukyu Islands of Japan. Records of this species have been documented in the Guangxi and Yunnan Provinces near the border with Vietnam and, for the first time from Vietnam, in Ha Giang Province. The new record of Bufo cf. gargarizans from Vietnam is from Ha Tinh Province. This species has never been reported from Vietnam so far south, about 550 km south from the previously known locality in Ha Giang Province. The female specimen was found in the Ha Tinh Province, Vu Quang National Park of central Vietnam and two specimens (male and female) were found Ha Giang Province. They are clearly distinguished from B. gargarizans and all the mentioned species by a specific color pattern on the belly and creamy-yellowish throat with large, bright red speckles. Genetic divergences of three Vietnam specimens from Ha Giang and Ha Tinh Provinces in the ND2 gene sequences between the B. sp. nov. and all other congeners ranged from 4.3% (with B. andrewsi) to 7.0% (with B. stejnegeri). We give a description of the morphological characters and coloration of the new record and provide an expanded diagnosis. | |

| Аннотация: | Based on the combination of molecular and morphological data, we herein report the second known finding of the xenodermid snake species Parafimbrios vietnamensis Ziegler, Ngo, Pham, Nguyen, Le & Nguyen, 2018. The male individual was found in the Yen Bai Province of northwestern Vietnam, more than 200 km from the type locality in Lai Chau Province. Genetic divergence between the newly-collected male and the holotype was low (1.7%), and is in agreement with morphological data that supports that they are conspecific. We give a detailed description of the morphological characters and coloration of the new record and provide an expanded diagnosis of P. vietnamensis. Parafimbrios is a poorly-understood genus, and our recent discovery brings the total number of known specimens of the genus to nine, 1/3 of them having been found in Vietnam (one specimen of P. lao and now two specimens of P. vietnamensis). | |

| Аннотация: | Herein, we describe a new agamid species of the genus Acanthosaura from Central Highlands of Vietnam: Gia Lai Province, Kon Chu Rang NR, and Kon Tum Province: Kon Plong and Ngoc Linh Mountain based on morphological and molecular data. Acanthosaura prasina sp. nov. is distinguished from all congeners by a combination of the following morphological characters. Acanthosaura prasina sp. nov. differs from A. capra, A. murphyi, and A. nataliae by the presence of a short spine on each side of the neck and a smaller body size. From the known species of "lepidogaster" complex and A. coronata it differs in the arrangement of dorsal crests with a distinct double row of vertebral scales, from A. brachypoda in a smaller body size, longer tail and limbs, fewer supra- and infralabials and coloration patterns with a white area on lips and shoulders; from A. lepidogaster by lacking a dark marking on the nape and the absence of a distinct diastema; from A. phongdienensis by lacking a dark marking on the nape. We provide a cyt b-based estimation of diversity of the genus Acanthosaura. A. prasina sp. nov. differs from A. phongdiensis, A. coronata, A. lepidogaster, A. armata, A. crucigera, A. nataliae, A. phuketensis, and Acanthosaura sp. SK in p-distances of 15.4, 24.5, 14.7, 14.6, 16.3, 14.6, 15.4, and 24.4%, respectively. The new species currently known from three localities from Central Highlands was recorded from 800 to 1700 m a.s.l. in the evergreen polydominant forests in the mountainous regions of Gia Lai and Kon Tum provinces. This is the 16th species of Acanthosaura and the ninth species of the genus from Vietnam. | |

| Аннотация: | Alien species can strongly impact local environments and compete against native species, which can lead to their extinction. Marsh frogs of the Pelophylax ridibundus complex are one of the most invasive amphibians in Northern Eurasia. It was previously thought that three water frog species of the genus Pelophylax (the marsh frog, P. ridibundus, the pool frog, P. lessonae and their hemiclonal hybrid, the edible frog, P. esculentus) inhabited Kaliningradskaya Oblast' along the Russian Baltic coast. However, based on our study of the intron-1 of the nuclear serum albumin gene, two other marsh frog species were detected (the Balkan marsh frog, P. kurtmuelleri, and the Anatolian marsh frog, P. cf. bedriagae) as well as putative hybrids between P. ridibundus and P. cf. bedriagae. The majority of individuals of P. ridibundus and hybrids between P. ridibundus and P. cf. bedriagae had mitochondrial (mt) DNA of P. lessonae, while all others featured the P. kurtmuelleri mtDNA. The prevalence of P. lessonae mtDNA haplotypes in populations of P. ridibundus from the Baltic Coast of Russia suggests that local individuals of the latter species originated from crosses between P. esculentus individuals. Two hypotheses could explain the records of P. kurtmuelleri and P. cf. bedriagae in the region. The establishment of local populations of the first species could have occurred via postglacial dispersal from the Balkan refugium. The origin of local P. cf. bedriagae could be an occasional introduction of individuals from the Ponto-Caspian region. Since our study is preliminary (19 individuals), in the future it would be important to continue the study of water frogs in Kaliningradskaya Oblast' and neighboring countries by applying multiple genetic markers. Additional genetic markers will enable researchers to study routes of dispersal and introductions of marsh frogs, to clarify peculiarities of their hybridization and distribution, and to evaluate the impact of P. kurtmuelleri and P. cf. bedriagae on the reproduction success of hybridogenous populations and abundance of local amphibians. | |

| Аннотация: | An analysis of the age structure of three water frog species (P. lessonae, P. ridibundus, P. esculentus) in the Middle Volga region of Russia was conducted. The skeletochronological method determined their maximum lifespans to be 7, 6, and 4 years, respectively. This study revealed specific characteristics of the age structure of Pelophylax frogs in relation to their taxonomic composition when cohabiting (population system type) and the degree of habitat transformation. Differences in body size and lifespan were observed among cryptic forms exhibiting mitochondrial DNA replacement and the presence of various types of heterozygous and homozygous alleles. Water frogs of the genus Pelophylax have a complex taxonomic structure, including hybrid species and morphologically cryptic forms, as well as massive mitochondrial DNA introgression. The aim of our paper was to analyze the age structure of three species of water frogs (P. lessonae, P. ridibundus, and P. esculentus) in the Middle Volga River region (European Russia). Based on the skeletochronological method, we determined their maximum lifespans of seven, six, and four years, respectively. The onset of sexual maturity in the marsh frogs occurred after two and four winterings in males and females (respectively), in the pond frog—one to two years, and in the edible frog—one to three years. This study revealed specific characteristics of the age structure of Pelophylax frogs in relation to their taxonomic composition when cohabiting (population system type) and the degree of habitat transformation. Differences in body size and lifespan were observed among cryptic forms exhibiting mitochondrial DNA replacement and the presence of various types of heterozygous and homozygous alleles. | |
