Background Only a few comprehensive studies have been carried out on parasites in amphibians and reptiles in Ukraine. This has resulted in identifying over 100 helminth species across these vertebrate groups. However, most of the studies were performed in the 20th century and the taxonomy of many parasites and their hosts has changed ever since, in addition to the discovery of new species and registrations of species that had not been previously known for Ukraine. In recent decades, there have been very few publications on helminths from amphibian or reptile hosts in this region. Notably, just one of these recent studies is a faunistic study, providing a list of helminths found in two species of green frogs – Pelophylax ridibundus (Pallas, 1771) and Pelophylax esculentus (Linnaeus, 1758). Therefore, it is clear that publishing datasets of modern records of helminths in these vertebrate groups, based on modern taxonomy, is an essential step in further studies of their parasitic diversity. Additionally, such study is important in terms of global climate change, the growing number of possibilities of invasion of alien species (both hosts and parasites) that might potentially become a threat to native biota and growing anthropogenic pressure on local populations of hosts that affect the parasites as well. In future, this study is planned to be used for the creation of a checklist of helminths of the herpetofauna of Ukraine. The present dataset is an inventory of various species of helminths parasitising common species of the herpetofauna in central, northern, western and southern Ukraine recorded during field studies in the 2021-2023 period. New information The dataset is the first one to represent the up-to-date and unified data on helminths of reptiles and amphibians of Ukraine. Previously, records of this group of organisms with reference to their hosts were presented as several separate records within the country. Currently, this is the largest dataset presenting geocoded records of non-human-related helminths in the fauna of Ukraine. It reports helminth species from 15 hosts (205 individuals), including eight amphibians and seven reptilian species found in various Ukrainian regions. A total of 47 helminth species have been documented in the research and during 2021-2023 period on the territory of northern (Kyiv and Zhytomyr), western (Lviv, Zakarpattia Ivano-Frankivsk), central (Vinnytsia, Dnipropetrovsk, Cherkasy, Zaporizhzhia and Poltava) and southern (Odesa) regions of Ukraine. The identified helminth species belong to the following phyla: Acanthocephala (Centrorhynchidae (2), Echinorhynchidae (2)); Nematoda (Acuariidae, Anisakidae, Cosmocercidae (3), Dioctophymatidae, Gnathostomatidae (1), Kathlanidae (1), Molineidae (7), Onchocercidae (1), Pharyngodonidae (1), Rhabdiasidae (6), Strongyloididae); Platyhelminthes (Diplodiscidae (1), Diplostomidae (2), Encyclometridae (1), Haematoloechidae (1), Leptophallidae (2), Macroderidae (1), Mesocestoididae, Opisthorchiidae (2), Plagiorchiidae (3), Pleurogenidae (2), Polystomatidae (3), Proteocephalidae (1), Strigeidae (1) and Telorchiidae (3)). Only some helminths in the dataset were not identified to species level. Material is stored in the collection of the department of Parasitology of the I. I. Schmalhausen Institute of Zoology NAS of Ukraine.

乌克兰常见爬虫类动物中发现蠕虫

背景 在乌克兰，仅对两栖动物和爬行动物的寄生虫进行了一些全面的研究。这导致在这些脊椎动物群体中鉴定出 100 多种蠕虫物种。然而，大多数研究是在 20 世纪进行的，除了发现新物种和登记乌克兰以前未知的物种外，许多寄生虫及其宿主的分类学自此发生了变化。近几十年来，关于该地区两栖动物或爬行动物宿主蠕虫的出版物很少。值得注意的是，这些最近的研究中只有一项是动物学研究，提供了在两种绿蛙中发现的蠕虫清单——Pelophylax rodibundus (Pallas, 1771) 和 Pelophylax esculentus (Linnaeus, 1758)。因此，很明显，基于现代分类学发布这些脊椎动物群体中蠕虫的现代记录数据集是进一步研究其寄生多样性的重要一步。此外，此类研究对于全球气候变化、外来物种（宿主和寄生虫）入侵的可能性不断增加（可能对本地生物群构成潜在威胁）以及对影响当地宿主种群的人为压力日益增加等方面具有重要意义。寄生虫也是如此。未来，这项研究计划用于创建乌克兰爬行动物蠕虫清单。本数据集是 2021-2023 年期间实地研究期间记录的乌克兰中部、北部、西部和南部寄生爬行动物常见物种的各种蠕虫的清单。新信息该数据集是第一个代表乌克兰爬行动物和两栖动物蠕虫最新且统一数据的数据集。此前，该组生物体及其宿主的记录在该国境内作为多个单独的记录提供。目前，这是乌克兰动物群中与人类无关的蠕虫地理编码记录的最大数据集。它报告了来自 15 个宿主（205 个体）的蠕虫物种，其中包括在乌克兰各个地区发现的八种两栖动物和七种爬行动物。在研究中，2021-2023年期间，北部（基辅和日托米尔）、西部（利沃夫、外喀尔巴阡伊万诺-弗兰科夫斯克）、中部（文尼察、第聂伯罗彼得罗夫斯克、切尔卡瑟、扎波罗热和波尔塔瓦）共记录了47种蠕虫。 ）和乌克兰南部（敖德萨）地区。已鉴定的蠕虫种类属于以下门：棘头动物门（Centrorhynchidae (2)、Echinorhynchidae (2)）；线虫纲(Acuariidae、Anisakidae、Cosmocercidae (3)、Dioctophymatidae、Gnathostomatidae (1)、Kathlanidae (1)、Molineidae (7)、Onchocercidae (1)、Pharyngodonidae (1)、Rhabdiasidae (6)、Strongyloididae)；Platyhelminthes（梁盘科 (1)、梁盘科 (2)、Encyclomeridae (1)、Haematoloechidae (1)、Leptophalidae (2)、Macroderidae (1)、Mesocestoididae、Opisthorchiidae (2)、Plagiorchiidae (3)、Pleurogenidae (2)、Polystomatidae (3)、Proteocephalidae (1)、Strigeidae (1) 和 Telorchiidae (3)）。数据集中只有一些蠕虫未被识别到物种水平。材料保存在乌克兰第二施马尔豪森动物研究所寄生虫学系的收藏中。
