NEW DATA ON PERILLUS BIOCULATUS (HETEROPTERA: PENTATOMIDAE) IN SERBIA: DO CLIMATE CHANGE AND A NEW FOOD SOURCE CONTRIBUTE TO THE TRUE BUG EXPANSION?

Perillus bioculatus (Fabricius, 1775) originates from North America, and was introduced to Europe at the beginning of the 20th century. The first findings of the species from nature in Serbia date back to 1996, after which the bug was not registered until 2018. After detecting one individual from 2018, we assumed that Perillus bioculatus would continue to spread throughout Serbia, and recent data have confirmed our suspicions. The paper presents literature and new findings from 2021 and 2022, as well as the conditioning of the spread of the species by the expansion of the range of new prey Ophraella communa LeSage, 1986 - also a non-native insect species in Europe, which was recorded in Serbia for the first time in 2020. In almost all localities from 2022, P. bioculatus was recorded on ragweed together with O. communa

FIRST RECORD OF DIMORPHOCORIS BEIERI WAGNER 1965 (HETEROPTERA: MIRIDAE) IN SERBIA

A new species for the fauna of Serbia - Dimorphocoris beieri Wagner, 1965, was caught on the Veliki Strešer, the highest peak of the Mount Vardenik. The species is endemic to the Balkan Peninsula, and in addition to Serbia, it has also been recorded in Montenegro on the Mount Durmitor (Wagner 1965, 1973; Protić et al. 1990). In addition to this, another species of the same genus was recorded in Serbia - D. saulii Wagner, on the Mount Stolovi (Protić, 2016)

ACROSTERNUM HEEGERI (HETEROPTERA: PENTATOMIDAE) IN SERBIA

The species Acrosternum heegeri Fieber, 1861 is a well-known member of the Mediterranean fauna in Europe and until recently was not recorded outside its natural range. In recent years, the presence of stable populations of the species in Budapest has been confirmed, and the first findings on the territory of Serbia are from 2013, when several overwintering adults were found under the bark of deciduous trees in Novi Sad. Since 2017, active individuals have been recorded throughout the season, for now mainly from the area of ​​Vojvodina. This bug is probably conquering new territories by transporting people and goods, but we assume that climate change is also responsible for establishing stable populations in new environments. The paper presents the findings of the species A. heegeri in Serbia, which were taken from the Alciphron database on insects in Serbia. A. heegeri is a polyphagous herbivore and has the status of an economically significant species in the Middle East because it causes damage in pistachio plantations

NEW FAUNAL DATA ON TRUE BUGS (HETEROPTERA) IN SERBIA

Three new true bugs were recorded in Serbia and species are listed with notes on records. Anisops sardeus Herrich-Schäffer, 1849; Henestaris laticeps (Curtis, 1836); Caenocoris nerii (Germar, 1847)

Providing a base for conservation of true bugs (Insecta, Heteroptera) and their saline habitats in Vojvodina (northern Serbia)

Saline habitats of the Pannonian region are recognised as conservation priorities by EU legislation, and represent rare semi-natural habitats in mostly agricultural lowland of northern Serbia. Saline habitats have a key role in conservation of numerous plant and animal species in Vojvodina, as well as characteristic communities of true bugs. These insects belong to one of the most diverse insect groups in saline habitats. Species Henestaris halophilus (BURMEISTER, 1835), Conostethus hungaricus WAGNER, 1941 and Solenoxyphus fuscovenosus (FIEBER, 1864) are saline specialists and can be found only in these habitat types. True bugs have great qualities for future biomonitoring projects concerning habitats such as saline grasslands and wetlands. During the study, species Hydrometra gracilenta HORVÁTH, 1899 and Solenoxyphus fuscovenosus (FIEBER, 1864) are recorded for the first time in Serbia

First record of Brachycerus sinuatus Olivier, 1807 (Coleoptera: Curculionidae) in Serbia

The unusually looking weevil species Brachycerus sinuatus Olivier, 1807 was collected in April 2019 in the vicinity of Preševo (southern Serbia). It is the first finding of this species for Serbia. By this data, its area of distribution is substantially extended westwards. Very precise data about the locality where it was found in contributing to the knowledge of its ecology.Publishe

Distribution and diversity of brown frogs (Rana spp., Anura, Amphibia) in Serbia

In this study, we present updated distribution data for all three brown frog species (Rana spp.) inhabiting Serbia. The data provided consists of newly collected field records and compiled data previously published in literature or via Internet. Of the three species found in Serbia, Rana dalmatina is the most widespread, present in all three altitudinal regions and all biogeographical regions. Rana graeca is confined to Mountain-valley altitudinal region in permanent fastflowing rivers or streams and it reaches its northern range boundaries in Serbia. Rana temporaria is the rarest of the three, with fragmented range restricted to the high mountains or few isolated lowland populations, and in the north-eastern Serbia, it is vicariant with R. graeca in canyons and gorges of montane rivers. The presence of Rana arvalis in Serbia is mentioned in literature but was not confirmed during the subsequent field surveys, so we consider it only as a potential species for the Serbian batrachofauna. The brown frog faunal composition of Serbia is identical to that of Albania, Bosnia and Herzegovina, Bulgaria, Greece, Macedonia and Montenegro, while it is somewhat different from that of Hungary and Romania and the most different from Croatia and Slovenia. Serbian brown frogs belong to European (R. temporaria) and South-European (R. dalmatina, R. graeca) chorotypes. All species of brown frogs present or potentially present in Serbia and their habitats are identified as great conservation priorities
