In the framework of a survey of arthropods in rest stops of Hungarian highways, 19 species of jumping plant lice were collected. Three species belong to the family Aphalaridae, one to Calophyidae, two to Liviidae, nine to Psyllidae and four to Triozidae. Two species (Livilla variegata and Trioza neglecta) are alien, non-indigenous species; the others are native to Hungary. The most abundant species were Calophya rhois, Cacopsylla melanoneura and Trioza neglecta. The specimens of C. melanoneura were found in 20, T. neglecta in 10 and C. rhois in 6 localities out of the 31 rest stops surveyed.
The first author observed Homotoma ficus (Linnaeus, 1758) larvae on several street and garden fig trees in the city of Pécs in southern Hungary at the end of May 2022. In the first week of June 2022, imagoes were already flying. This is the first observation of this species in Hungary, together with the first report of the family Homotomidae. A diagnosis and illustrations of adults and larvae in Hungary with 21 figures are given.
A new species (Rotundabaloghia (Circobaloghia)nagyi sp. nov.) of the rotundabaloghid mites is described based on females and male collected in bamboo leaf litter in Cameroon. The new species differs from the other Afrotropical rotundabaloghid mites in following character combination: female genital shield with long apical process, the setae v7 and v8 long and pilose, v6 long and smooth, v2 short and needle-like, female genital, dorsal and ventral shields are ornamented by irregular pits, sternal setae short and needle-like. This character combination is unknown within the African rotundabaloghids.
Fifteen new occurrences of ragweed leaf beetle (Ophraella communa LeSage, 1986) are presented from Hungary based on targeted faunistic investigations and the results of our call for citizen scientists. All records are concentrated on the nearby regions of Budapest, suggesting that the species was introduced to this northern central region of the country by human activity. The high number of new occurrences indicates that the species is steadily established in this region. In contrast, the natural dispersal from the neighbouring southern countries seems not to cross the Hungarian borders yet.
Date-locality-host records for 37 mite species of 15 families are presented for Hungary and Austria. These results include the first record of eight species for Hungary, viz. Charletonia krendowskyi (Feider, 1954), Marantelophus rudaensis (Haitlinger, 1986), Cunaxa gazella (Berlese, 1916), Eupalopsellus oelandicus Sellnick, 1949, Tydeus lindquisti (Marshall, 1970), Neoseiulus dungeri (Karg, 1977), Neoseiulus tauricus (Livshitz et Kuznetzov, 1972) and Proctolaelaps drosophilae Karg, Baker et Jenkinson, 1995. Observations on habitat preferences, plant associations, co-occurrences and feeding behaviour are also provided.
Cimex lectularius, the common bedbug is an important, emerging pest of both veterinary and medical importance. Here a recently discovered, genetically distinct new species of the C. lectularius group is described morphologically, as Cimex pulveratus Hornok sp. nov.
A new species Nenteria lii sp. n. is described on the basis of adults and deutonymphs collected in bamboo (Phyllostachys sp.) leaf litters in Xinxiang (Henan Province, China). The new species is very similar to the species Nenteria japonensis Hiramatsu, 1979, but the apical process of the female genital shield rounded and smooth in the new taxon, but serrate in the previously described Japanese species. A new key to the Eastern-Palearctic Nenteria species is given. A list of the collected bamboo leaf litter associated mites is presented.
The hypopi of the species Sancassania chelone Oudemans, 1916 were collected from four pest beetle species, namely Melolontha melolontha (Linnaeus, 1758); Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta Poda, 1761. The infestation rate was the highest in H. aequinoctialis (80%), while it was 50%, 28% and 13% in M. hippocastani, M. melolontha and T. hirta, respectively. The majority of the mites were found on wings in case of the two Melolontha species, in contrary, the mites were present on the abdomen of the H. aequinoctialis and T. hirta. Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta (Poda, 1761) are new host species of S. chelone.
The pine pest, Cenopalpus lineola (Canestrini and Fanzago, 1876) was discovered after 45 years again in Hungary. Proto-, deutonymphs, male and female specimens were collected, therefore a new and detailed re-description are presented with description of the leg chaetotaxy of the immature stages.
Three eriophyoid species are recorded for the first time in Hungary, viz. Paraepitrimerus erigeronsis Xue et Hong collected from Erigeron annuus (L.) Pers. (Asteraceae), Phyllocoptes parvulus (Nalepa) from Potentilla reptans L. (Rosaceae) and Aceria salicina (Nalepa) from Salix alba L. (Salicaceae). In addition, supplementary description of the vagrant phyllocoptine mite, Paraepitrimerus erigeronsis, and the deuterogynous and leaf margin rolling Aculus craspedobius (Nalepa) from Salix integra Thunb. (Salicaceae) is provided.
