The accelerating pace of digital and environmental transformation presents both opportunities and challenges for small- and medium-sized enterprises (SMEs) across the European Union. While digital tools like data analytics can significantly boost operational efficiency and sustainability, many SMEs lack the internal capabilities to fully leverage them. This study investigates how upskilling employees in digital competencies can help SMEs enhance their digital maturity and achieve long-term resilience. A descriptive trend analysis was based on Eurostat datasets focusing on enterprise size categories and examining indicators such as data analytics activities, the prevalence of ICT training, and difficulties encountered in recruiting ICT specialists. Visualized through Tableau, the data reveal notable disparities: in 2023, only 14.5% of small and 33.8% of medium-sized enterprises with high digital maturity performed data analytics, compared to 59.4% of large enterprises. Despite clear demand, only 5% of small and 20% of medium enterprises attempted to recruit ICT-skilled personnel, frequently citing a lack of qualified candidates or unaffordable salary expectations. SMEs rely on their own staff for data analytics tasks, yet many still do not offer structured training. While countries like Finland stand out, with 61.7% of medium enterprises providing ICT upskilling, others fall well below the EU average. These results underscore that internal skill development is not just a workaround but a strategic necessity for SMEs striving to keep pace with digital demands, overcome labor market constraints, and build a foundation for sustainable growth.

Japanese species of the subgenera Oreophila Lackschewitz and Parormosia Alexander of the genus Ormosia Rondani (Limoniidae) are revised. Two new species Ormosia (Oreophila) komazawai Kato & Kolcsár, sp. nov. and Ormosia (Parormosia) phalara Kato & Kolcsár, sp. nov. are described. The identities of all Japanese species of the two subgenera are clarified and redescribed with images of habitus and wings, and drawings of male and female terminalia. The first DNA barcode sequences of the species Ormosia (Parormosia) diversipes Alexander and Ormosia (Parormosia) phalara Kato & Kolcsár, sp. nov. are also provided. A key to, and distribution maps of, the Japanese species are provided.

The cranefly (Tipuloidea) fauna of the Western Balkans is still poorly known. In this study, occurrence data of 77 species is reported, of which two species are newly recorded for Albania, eight species for Bosnia and Herzegovina, twelve for Croatia, and seven for Slovenia, respectively. A new species, Baeoura neretvaensis Kolcsár & d’Oliveira, sp. nov. is described from Bosnia and Herzegovina, Montenegro, and Slovenia. Images of the habitus, wing, and male and female terminalia of the new species are provided. Furthermore, images of male terminalia and wings of thirteen additional species are presented.

A morphological and molecular study of 17 Cylindrotomidae species revealed that the two subspecies of Cylindrotoma distinctissima , the Nearctic C. americana Osten Sacken, 1865, stat. reval. and the Palearctic C. distinctissima (Meigen, 1818), represent separated lineages and consequently are raised to species level. Cylindrotoma japonica Alexander, 1919, syn. nov . and C. distinctissima alpestris Peus, 1952, syn. nov. are now known to be junior synonyms of C. distinctissima . Triogma kuwanai limbinervis Alexander, 1953, syn. nov. and T. nimbipennis Alexander, 1941, syn. nov. are now placed into synonymy under Triogma kuwanai (Alexander, 1913). The Japanese Cylindrotomidae are all redescribed and all available literature and distribution data are summarised. Supplementary descriptions and illustrations for male and female terminalia of Cylindrotoma nigriventris Loew, 1849, Diogma dmitrii Paramonov, 2005, Liogma nodicornis (Osten Sacken, 1865), Phalacrocera replicata (Linnaeus, 1758), P. tipulina Osten Sacken, 1865, and Triogma trisulcata (Schummel, 1829) are provided. The following new distribution records are outlined; Diogma caudata Takahashi, 1960 from Arkhangelsk Oblast, Russia; D. glabrata (Meigen, 1818) from Belarus, Latvia, and Altai Republic, Amur Oblast, Novgorod Oblast, Magadan Oblast, Samara Oblast, and Kuril Islands (Shikotan I and Paramushir I) in Russia; Liogma serraticornis Alexander, 1919 from Khabarovsk Krai, Russia; Phalacrocera replicata from Khabarovsk Krai, Russia; and the presence of Cylindrotoma nigriventris in Altai Republic, Russia is confirmed.

Holorusia Loew, 1863 (Diptera: Tipulidae) is a relatively large crane fly genus with a wide distribution in the Afrotropic, Australasian–Oceanian, Eastern Palearctic, Oriental and Nearctic Regions. Although the genus is well known to include the largest crane fly species, the immature stages are, thus far, only described for the larva and pupa of the North American Holorusia hesperea Arnaud & Byers, 1990. In this study, we describe for the first time the egg, larva and pupae of the Japanese Holorusia mikado (Westwood, 1876). Larvae were collected from semi-aquatic habitats, from slow flowing areas of streams and small waterfalls where leaf litter accumulates; the larvae are detritivores and feed on wet, decomposing leaves. The larvae were reared to adults in the laboratory. Morphological characters of immature stages discussed with comparison with the North American H. hespera . Male and female genitalia are illustrated and described in detail for the first time.

Fungus gnats (Sciaroidea) are a globally species rich group of lower Diptera. In Europe, Fennoscandian peninsula in particular holds a notable diversity, ca. 1000 species, of which 10 % are still unnamed. Fungus gnats are predominantly terrestrial insects, but some species dwell in wetland habitats. Eight new fungus gnat species, belonging to the families Keroplatidae ( Orfelia boreoalpina Salmela sp.n.) and Mycetophilidae ( Sciophila holopaineni Salmela sp.n., S. curvata Salmela sp.n., Boletina sasakawai Salmela & Kolcsár sp.n., B. norokorpii Salmela & Kolcsár sp.n., Phronia sompio Salmela sp.n., P. reducta Salmela sp.n., P. prolongata Salmela sp.n.), are described. Four of the species are known from Fennoscandia only whilst two are supposed to have boreo-alpine disjunct ranges, i.e. having populations in Fennoscandia and the Central European Alps. One of the species probably has a boreal range (Finnish Lapland and Central Siberia). Type material of Boletina curta Sasakawa & Kimura from Japan was found to consist of two species, and a further species close to these taxa is described from Finland. Phronia elegantula Hackman is redescribed and reported for the first time from Norway. DNA barcodes are provided for the first time for five species.

A new species of the TipulasubgenusMediotipula is described from the south-eastern part of Albania, south-eastern Europe. Morphologically, the new species is most similar to T. (M.) stigmatella Schummel, 1833, but differs mainly with respect to males, having a distinctly shaped posterior margin of tergite 9–10, a widened outer gonostylus and a series of details of the inner gonostylus (anterior end of the anterior arm, shape of the posterior arm), as well as having more bulbous and rounded hypogynal valves in the females. Further morphological differences of the male terminalia between allopatric populations of T. (M.) stigmatella in the Carpathians and Balkans, south-eastern Europe, are discussed.

New records are provided for Limoniidae and Pediciidae from Croatia, with new distribution records for species in 12 different genera. Four genera and 18 species are newly recorded for Croatia. Until now, including this data, 87 Limoniidae and eight Pediciidae have been recorded from Croatia. In this paper we confirm presence of Ormosia (Oreophila) bergrothi (Strobl, 1895) and we give the first records of Dicranota (Paradicranota) pavida (Haliday, 1833) and Molophilus (Molophilus) repentinus Starý, 1971 from Balkan Peninsula.

Three new species of the genus Pedicia, subgenus Crunobia (Diptera: Pediciidae) belonging to the staryi group are described on the basis of a combination of molecular and morphology datasets, and a key to discriminate between species of the subgenus Crunobia is added. Geographic projection of the identified taxa suggests insular-like distribution and shows the importance of the Carpathians as a genetic center which is home to an exceptionally high aquatic diversity in Europe.

Mycomya supernivea Nakamura and Saigusa, 2020 is a recently described large-sized cold-adapted fungus gnat species known from the island of Hokkaido and the northern part of Honshu in Japan. This study reports the species for the first time from Shikoku Island and the central part of Honshu, indicating that the species is more widely distributed throughout the Japanese islands. Additionally, the systematic position of M. supernivae within the genus Mycomya is discussed, and it is placed under the subgenus Mycomya s. str. within the species group M. matrona .
