1. Paragomphus matroka sp. nov. - a new Hooktail species from the rainforests of eastern Madagascar (Odonata: Gomphidae)Matjaž Bedjanič, Rafał Bernard, Bogusław Daraż, Kuang-Ping Yu, 2026, izvirni znanstveni članek Povzetek: Paragomphus matroka sp. nov. (holotype ♂: Madagascar, taolagnaro district, iaboakoho, Réserve de Ressources Naturelles de la Forêt Naturelle de Tsitongambarika, Ampasy; Lat. -24.57840°, Lon. 47.14493°; 4.xii.2024; to be deposited in RMNH, Leiden), is described as new to science. The new endemic species is known only from the holotype, the paratype deposited in the MNHN, Paris, and an additional specimen deposited in NHRS, Stockholm. It has been recorded from three localities in the eastern part of the island, scattered over a distance of 1,033 km, within the Madagascar Humid Forests ecoregion. despite the pronounced variation in the colour pattern, the three known specimens are interpreted as conspecific based on concordant diagnostic morphological characters, particularly the nearly identical structure of the secondary genitalia and cerci. The new species is related to P. fritillarius (Selys, 1892) and P. sofiae Bernard & daraż, 2026. From these two more brightly coloured, spotted Hooktail species, P. matrokasp. nov. differs in its considerably darker colouration, a reduced pattern of smaller light markings on the synthorax, and clearly different secondary genitalia. The discovery of a new species underlines the need for additional intensive odonatological studies in Madagascar. improving knowledge of species distributions, taxonomy, phenology and ecological requirements is crucial, especially in the context of threat assessments and conservation of endemic odonate fauna.

2. Testing species boundaries of an unknown Dolomedes (Araneae, Dolomedidae) morphospecies from isolated islandsGrégory Cazanove, Kuang-Ping Yu, Brice Derepas, Arnaud Henrard, 2025, zaključena znanstvena zbirka raziskovalnih podatkov Povzetek: Raft spiders, family Dolomedidae, represent a group of spiders with 7 genera distributed near globally well known for a semi-aquatic lifestyle. One of the iconic genera representing such a unique lifestyle is the largest and diverse dolomedid genus Dolomedes. Although Dolomedes is well surveyed in parts of its distribution, its diversity in the tropics remains largely unknown, such as the western Indian Ocean region with most of the islands unsurveyed. Recent expeditions to Madagascar and La Réunion Island discovered a series of specimens that appear to belong to an unknown morphospecies of Dolomedes, exhibiting varying degrees of differences in the diagnostic characteristics. To further test and define their species boundaries, we include molecular evidence followed by species delimitation analyses. Our findings indicate that specimens from both islands are conspecific. Consequently, we introduce a new species to science, Dolomedes reuniascar sp. nov., providing detailed illustrations, descriptions of its variations and ecological characteristics. Based on our observations and existing literature, we speculate that the presence of this species on the two isolated islands could be attributed to either highly efficient dispersal abilities, such as ballooning of spiderlings, or human-mediated introduction events.

4. Five hidden species in a widespread European vertebrate : disentangling the alpine newt cryptic species complex through genomic phylogeographyStephanie Koster, Anagnostis Theodoropoulos, Wouter Beukema, Johanna Ambu, Wiesław Babik, Daniele Canestrelli, David Stanković, 2026, izvirni znanstveni članek Povzetek: Through genomic phylogeography, previously unrecognised biodiversity can be revealed. The alpine newt serves as a case in point: this taxon carries highly distinct mtDNA clades and has a severely fragmented range. We obtain genome-wide data with target enrichment by sequence capture to delineate cryptic species and disentangle their phylogenetic relationships. Furthermore, we explore potential niche divergence and glaciation-driven distribution dynamics. On the basis of the uncovered genetic structure, we distinguish five main groups that we propose should be treated as distinct species. Limited interspecific genetic admixture often occurs away from current contact zones between these species, in line with a scenario of current range reduction, compared to the Last Glacial Maximum. A decline in suitable habitat also explains the fragmented nature of current species ranges. We uncover pronounced mito-nuclear discordance. We show that an ancient mtDNA lineage endemic to the Vlasina Plateau on the border between Serbia and Bulgaria, previously interpreted to be a ‘ghost lineage’, in fact represents a distinct species. However, it is nested considerably deeper inside the alpine newt species complex than mtDNA suggests. Our study illustrates how genomic phylogeography allows intricate evolutionary histories to be untangled.

5. The Other Side of the Coin: Taxonomic Updates and Species Key of Herennia (Araneae: Nephilidae)Matjaž Kuntner, Kuang-Ping Yu, Eva Turk, Klemen Čandek, Matjaž Gregorič, Gregory J. Anderson, Jonathan A. Coddington, Ren-Chung Cheng, 2026, izvirni znanstveni članek Povzetek: Coin spiders of the genus Herennia Thorell, 1877 are species-rich nephilids distributed across South, East, and Southeast Asia and Australasia. They are notable for ladder-shaped arboricolous webs, extreme sexual size dimorphism, and complex sexual behaviors. The most recent revision recognized 11 species, only 4 of which were described from both sexes. Here, we present a taxonomic revision integrating new morphological and molecular data and recognize 14 species. We describe three new species—H. eva Kuntner from Sulawesi, H. maj Kuntner from Vietnam, and H. tsoi Kuntner et al. from Taiwan—and document previously unknown males of H. oz Kuntner, 2005 from Australia and H. tone Kuntner, 2005 from the Philippines. We also extend the known distribution of H. papuana Thorell, 1881 from New Guinea to Australia. Although several molecular species-delimitation analyses suggest H. oz and H. etruscilla Kuntner, 2005 may be conspecific, consistent and diagnostic morphological differences support their recognition as distinct species. We provide an updated identification key to all valid Herennia species. Additional undescribed endemics are likely to occur across the Asian mainland and the rapidly disappearing forests of Southeast Asian and Australasian islands. The genus’ biogeographic pattern, shaped by an ancestrally broad distribution spanning the Wallace Line, may reflect repeated loss and regain of ballooning, a hypothesis that warrants experimental and comparative testing.

6. Phylogenetic position of the genus Chaetoniphargus Karaman et Sket (Crustacea: Amphipoda: Niphargidae) from dinamic karst : An extreme case of homoplasyBoris Sket, Gordan S. Karaman, 2018, izvirni znanstveni članek Povzetek: An alternative, phylogenetically grounded taxonomy of the recently described Chaetoniphargus lubuskensis Karaman & Sket (Crustacea: Amphipoda: Niphargidae) is presented. The recently described new genus and species, Chaetoniphargus lubuskensis from Dinaric Karst, has formerly only been taxonomically evaluated by a classical approach, based on morphology. Species of genera Niphargobatoides, Niphargobates, Chaetoniphargus, differ from Niphargus spp. mainly by slightly elevated number of maxilla I spines, by gradual reduction of maxillary and mandibular palps, by a strong reduction of urosomal structures. Molecularly, they appear to be nested within the Niphargus tree, but separately. Their collective separation from Niphargus would make the genus Niphargus paraphyletic, but for the low number of these species practically without diminishing the confusing diversity of it. A molecular phylogenetic analysis would include all here studied niphargid species as belonging to Niphargus. The gradual change in morphology of mentioned niphargids produces a smooth transition between Niphargidae and unrelated Metacrangonyctidae. Since other facts speak against the relatedness of both families, this is an additional case of convergence, demonstrating the need of molecular analyses when we speculate on phylogenetic relations within Amphipoda.

7. Sites of rare form of auricula (Primula auricula var. Tolminensis nom. prov.) in the southern Julian AlpsAnka Rudolf, Branko Vreš, Igor Dakskobler, 2018, izvirni znanstveni članek Povzetek: In the southern Julian Alps under the northwestern ridge of Kobilja Glava above the pasture of Lom and on the slopes of Krikov Vrh between pastures of Lom and Kuk (Podkuk), on stony shady pasturelands and in limestone and dolomite rocks at elevations ranging between 1,100 and 1,200 m, two forms of auricula (Primula auricula) occur side by side. The more common specimens with bright (deep) yellow flowers are accompanied and outnumbered by plants with slightly smaller stems and distinctly pale, lemon-coloured flowers. Although Primula auricula as a species boasts impressive variability in the size and shape of leaves and their meal covering, as well as in the size and colour of flowers, we have not observed populations with such distinctly pale yellow flowers anywhere else in Slovenia. The taxa described elsewhere in the distribution area of Primula auricula s. lat. (including those that supposedly belong to Primula lutea) are distinctly different from the studied auriculas, at least in terms of flower colour. We infer that they are a new variety, Primula auricula var. tolminensis (the Tolmin auricula), but will have to conduct further research to corroborate this conclusion. In this paper we describe its sites and current distribution.

9. Notes on Abutilon (Malvaceae) in the Mediterranean and MacaronesiaFilip Verloove, 2025, ni določena Povzetek: Recent field- and herbarium studies in the genus Abutilon in the Mediterranean and Macaronesia yielded some noteworthy results. The invasive South American weed A. grandifolium is reported for the first time from Algeria. A recent claim of A. grandiflorum from the Canary Islands is erroneous and referable to A. grandifolium. Historical records of the South African A. sonneratianum from Madeira are also discussed. This species is included in the list of invasive species in Portugal. However, it is shown that the invasive species in Portugal (Madeira) is A. grandifolium, not A. sonneratianum.

10. Revision of Xanthopsis bodracus Makarenko, 1956 (Crustacea: Decapoda) from the Palaeogene of UkraineVitaly Dernov, 2025, izvirni znanstveni članek Povzetek: The present article constitutes a revision of the decapod crustacean species Xanthopsis bodracus Makarenko, 1956 from the early Lutetian (Eocene, Palaeogene) of the Crimean Peninsula, southern Ukraine. The distinctive morphological characteristics of Xanthopsis bodracus enable its classification within the genus Harpactoxanthopsis Via Boada, 1959, as the type series of Xanthopsis bodracus precisely aligns with the diagnostic criteria of this genus. Of the five species in the genus Harpactoxanthopsis, Xanthopsis bodracus is morphologically closest to Harpactoxanthopsis quadrilobatus(Desmarest, 1822). However, there are currently insufficient grounds to confidently synonymise Xanthopsis bodracuswith Harpactoxanthopsis quadrilobatus, as the poorly preserved type material, of which only a part has been preserved, does not allow this. In view of this, Xanthopsis bodracus has been revised as Harpactoxanthopsis sp. The Palaeogene decapod assemblages of Crimea consist of five genera including Coeloma A. Milne-Edwards, 1865, Protocallianassa Beurlen, 1930, Arcticocarcinus Shweitzer et al., 2016, Xanthopsis M’Coy, 1849, and Harpactoxanthopsis Via Boada, 1959.
