This journal publishes original works in the fields of <em>animal taxonomy</em> and <em>systematics</em>, <em>zoogeography</em>, <em>animal ecology</em> and <em>behaviour</em>, <em>population biology</em>, <em>biodiversity studies</em> and <em>nature conservation</em> problems of international interest. Studies of extinct as well as living animals are included. Besides research articles, reviews and opinion papers are very welcome. Publishing short communication, faunistic records, checklist, catalogue or new species for a given area is not the focus of our publishing policy. This journal is fairly rapid (the average time from submission to publishing was about 10 months in the last decade). Acta Zoologica Academiae Scientiarum Hungaricae is published quarterly in four issues in February, May, August, and November. The journal is indexed in BIOSIS, Biological Abstracts, Abstracts of Entomology, Forest Science Database, Current Contents, Science Citation Index Expanded, Zoological Records, Scopus, DOAJ.</p> https://ojs3.mtak.hu/index.php/actazool/article/view/12873 New genus and new species of the subfamily Colpopterinae (Hemiptera: Fulgoroidea: Nogodinidae) from Colombia 2023-12-22T08:15:23+00:00 Vladimir M.

The aim of the research was to examine the possibility of modifying the standard method, which is a standard in the Republic of Serbia, for determining the age of hares based on the mass of their lenses in order to shorten its duration. Additionally, the goal was to investigate whether there was a difference in the age structure determined by the standard and modified methods. For the purpose of processing and analyzing samples, a total of 410 hare heads were collected from hunting grounds in Central Serbia and Vojvodina, and only heads with intact lenses of both eyes (399) were included in the analysis, resulting in the examination of 798 lenses. It was determined that there was no statistically significant difference in the lens mass between the standard and modified methods, both for age categories of hares up to one year and over one year. High correlation coefficients were found, indicating a strong relationship between the lens mass obtained by the standard and modified methods within both age categories. Furthermore, the real growth rates of hares determined by the standard and modified methods were equal.</p> 2023-12-20T00:00:00+00:00 Copyright (c) 2023 Nikola Mihajlović, Stefan Stepić, Vukan Lavadinović, Dejan Beuković, Aleksandar Ignjatović, Zoran Popović https://ojs3.mtak.hu/index.php/actazool/article/view/12338 A new species of the planthopper genus Polychornum Gnezdilov, 2021 (Hemiptera: Caliscelidae: Ommatidiotinae) extends the distribution of the genus and tribe Augilini Baker to Africa 2023-11-17T10:24:03+00:00 Vladimir M.

It represents the first properly diagnosed and described snail taxon from these deposits, despite numerous earlier reports of gastropod occurrences. This new species is characterized by a depressed, mostly smooth shell, three spiral carinae on the ventral side (inside the umbilicus), and an upward-turning aperture. The last feature characterizes two European fossil snail genera, the cyclophoroidean <em>Ferussina</em>, and the stylommatophoran <em>Strophostomella</em>. The new species is classified in the former group due to its nearly circular aperture, and the presence of conspicuous spiral carinae. In contrast, the aperture of most stylommatophoran genera (including <em>Strophostomella</em>) is semilunar, and if raised sculptural elements are present, they are mostly radially oriented. The identification of this new taxon in the uppermost Cretaceous of Romania represents an important range extension for the genus <em>Ferussina</em>, and adds it to the brief list of European clades that appear to have survived the mass extinction event at the Cretaceous-Paleogene boundary.</p> 2023-10-06T00:00:00+00:00 Copyright (c) 2023 Barna Páll-Gergely; János Magyar, Zoltán Csiki-Sava, Gábor Botfalvai https://ojs3.mtak.hu/index.php/actazool/article/view/11251 Revision of the oribatid mite genus Amboroppia (Acari, Oribatida, Oppiidae), with description of a new subgenus and species from Mexico 2023-09-20T08:52:27+00:00 Sergey G.

Bienkowski bienkowski@yandex.ru <p>Three new species of the genus <em>Chrysolina</em> Motschulsky, 1860, namely <em>Сh. caspari</em> sp. n., <em>Ch. melchiori</em> sp. n., and <em>Ch. balthazari</em> sp. n. are described from Sichuan and Yunnan Provinces of China. These species have rare or unique features. In <em>Ch. caspari</em> sp. n. the shape of the last maxillary palpomere (it is shorter and narrower than the penultimate one) is a rare case in the genus <em>Chrysolina</em>. Among Chinese species, this shape of maxillary palpi is known only in one species, <em>Ch. pieli</em> Chen, 1936. In <em>Ch. melchiori</em> sp. n. the relief of elytral surface (strongly reticulated irregular funnels bearing a puncture at the bottom, separated by smooth intervals) is unique for the genus <em>Chrysolina</em>. In <em>Ch. balthazari</em> sp. n. the relief of elytra (alternation of wide convex intervals between pairs of rows and very narrow flat or slightly convex intervals between rows of one pair) is well distinguishable from most Chrysolina members. Due to this feature, the new species can only be close to <em>Ch. jinxiaoae</em> Ge in: Daccordi, Ge, Cui, Yang, 2011 from North Sichuan. Photographs of habitus, external characters, and male aedeagi are presented.</p> 2023-08-25T00:00:00+00:00 Copyright (c) 2023 Andrzej O.

The similarity of the structure of the aedeagus of <em>Ablapsis compressipes</em> Reitter, 1887 and some species of the subgenus <em>Prosoblapsia</em> Skopin et Kaszab, 1978 (genus <em>Blaps</em> Fabricius, 1775) gives a base to transfer the taxon <em>Ablapsis</em> Reitter, 1887 into the genus <em>Blaps</em> as a separate subgenus (<em>Ablapsis</em> stat. resurr.). <em>Blaps tentyrioides</em> Seidlitz, 1893 (= <em>Blaps socia</em> Seidlitz, 1893) is designated as a type species of the subgenus <em>Protoblaps</em> Bauer, 1921. As the genera <em>Protoblaps</em> Bauer, 1921 and <em>Genoblaps</em> Bauer, 1921 have one type species and the aedeagal structure of type species of <em>Ablapsis</em>, <em>Protoblaps</em> and <em>Prosoblapsia</em> is similar, the new synonymy is proposed: <em>Ablapsis</em> Reitter, 1887 = <em>Protoblaps</em> Bauer, 1921 syn. n. = <em>Genoblaps</em> Bauer, 1921 syn. n. = <em>Prosoblapsia</em> Skopin et Kaszab, 1978, syn. n. Analysis of imaginal and larval structures of the species here united in the taxon <em>Lithoblaps</em> Motschulsky, 1860 and other members of <em>Blaps</em> showed that differences between these two groups are comparable with those between other genera of the subtribe and, therefore, the former taxon is here regarded as a distinct genus <em>Lithoblaps</em> gen. resurr. Thus, 100 species and subspecies (marked as comb. n. or comb. resurr.) are transferred from <em>Blaps</em> to <em>Lithoblaps</em>. The additional new combination is established: <em>Dila platythorax</em> (Gemminger, 1870), comb. n. (from <em>Blaps</em>).

Only five species of the family Lymnaeidae have been recorded from this subcontinent so far. In February 2023, a few specimens of <em>Radix rufescens</em> (J. E. Gray, 1822) have been collected from the stream at Wadi Tiwi, NE Oman. The shell, female part of the reproductive organs, prostate, paraeputium and phalloteca are presented. Cytochrome oxidase subunit I (COI) sequences confirmed the assignment of these specimens to <em>R. rufescens</em>, known from Nepal, Bangladesh, and Myanmar, not from the Arabian Peninsula. Either <em>R. rufescens</em> is the sixth lymnaeid species inhabiting Arabia, or at least some of the records of <em>R. natalensis</em> (Krauss, 1848), whose shells are hardly discernible from the ones of <em>R. rufescens</em>, should be interpreted as misidentified <em>R. rufescens</em>.

Contrary to differences in body size, little is known about sexual shape dimorphism in anurans. Here we investigated intersexual shape differences in <em>Bufo verrucosissimus</em> (Pallas, 1814) by taking 27 linear measurements to characterize body morphology of 23 males and 23 females. Relative to their overall body size, males had longer limbs and larger eyes, while females displayed larger parotoid glands and had wider heads. We speculate that these intersexual differences may have arisen due to differences in natural and sexual selection regimes acting on males and females, especially during foraging, mate searching, or intrasexual competition.</p> 2023-06-30T00:00:00+00:00 Copyright (c) 2023 Cantekin Dursun, Nurhayat Özdemir, Serkan Gül https://ojs3.mtak.hu/index.php/actazool/article/view/10247 New Acantharadus and Kema species (Hemiptera, Heteroptera, Aradidae) from Halmahera Island, Indonesia 2023-07-03T11:44:00+00:00 Tamás Vásárhelyi tvasarhelyi@gmail.com Ernst Heiss aradus@aon.at <p><em>Acantharadus flora</em> sp. n. and <em>Kema pamae</em> sp. n.
