A new cave Pseudoscorpion (Pseudoscorpiones: Chthoniidae): Chthonius (Chthonius) lupinus n.sp. from Bosnia-Herzegovina

A new cavernicolous pseudoscorpion pertaining to the genus Chthonius (Chthonius) C. L. Koch, from Herzegovina (Bosnia-Herzegovina) is erected. Its relations with close congeners are briefly discussed. The new species Chthonius (Chthonius) lupinus n. sp. is an endemic form presently known only from its type locality (Vučija pećina Cave, Mt. Leotar, nr. Trebinje, Herzegovina)

On two new cave species of Pseudoscorpions (Neobisiidae, Pseudoscorpiones) from Herzegovina and Dalmatia

A careful analysis of samples of pseudoscorpions (Neobisiidae, Pseudoscorpiones) from two underground habitats, one near Trebinje (Herzegovina) and the other from the National Park Paklenica (Croatia), has yielded two species of the genus Roncus L. Koch new to science, Roncus tribunus n. sp. and R. argyrunti n. sp. Both new species are described thoroughly, illustrated, and diagnosed. Some biogeographical and evolutionary characteristics of the two taxa are briefly discussed. [Projekat Ministarstva nauke Republike Srbije, br. 173038

Biodiversity of Roncus L. Koch in Montenegro - Roncus teutae n. sp. from Mt. Orjen (Neobisiidae, Pseudoscorpiones)

A single species of Roncus L. Koch, 1873, which was collected in the Baretina Lokva on Mt. Orjen, Montenegro, is new to science (R. teutae n. sp.) and described herein. Its diagnostic characters are illustrated and their distribution is provided. The possible establishment of this species of Roncus is presented briefly in view of the importance and analysis of its diagnostic characters.

A new cave pseudoscorpion from Dalmatia - Microchthonius tragurion n. sp. (Chthoniidae, Pseudoscorpiones)

A new eyeless pseudoscorpion, Microchthonius tragurion n. sp., from a cave in Blizna Donja (near Trogir), from the Jama kod Gomilje Pit, Dalmatia, is described. This new false scorpion differs from all other congeners. There exists a probability that this new taxon is a relict of a tropical fauna incorporating the once northern and tropical area, now representing the subtropical part of the Mediterranean. Morphometric ratios, figures and linear measurements of the new taxon are presented in detail. [Projekat Ministarstva nauke Republike Srbije, br. 173038

Roncus ivansticae (Neobisiidae, Pseudoscorpiones): A new epigean species from eastern Serbia

A single species of Roncus L. Koch, 1873, which was collected in eastern Serbia and is new to science (R. ivansticae n. sp.) is described herein; the diagnostic characters are illustrated and their distribution is provided. The possible establishment of two species (or supraspecific?) groups of Roncus is presented briefly in view of the importance of some diagnostic characters

A new endemic representative of the genus Rascioduvalius S. B. Ćurčić, Brajković, Mitić & B. P. M. Ćurčić from Mt. Zlatibor, Western Serbia (Trechini, Carabidae, Coleoptera)

A new species of cavernicolous and endemic trechine ground beetles Rascioduvalis zlatiborensis n. sp., is described and diagnosed in the present paper. Also, all important taxonomic features are considered and illustrated. The type specimens of the new species were collected from the Markova (= Ršumska) Pećina Cave, village of Gornji Ljubiš, Mt. Zlatibor, Western Serbia. The new species and its congeners belong to a separate phyletic lineage of Tertiary age. All members of Rascioduvalius S. B. Ćurčić, Brajković, Mitić & B. P. M. Ćurčić are distributed in Western Serbia only, where they have gone through intense differentiation and radiation due to evolution of the karstic relief

The actual relevance of ecological corridors in nature conservation

The paper considers theoretical and applied foundations of the concept of the ecological corridors in nature conservation. Their relevance comes from recent ecological phenomenon of habitat fragmentation which is rapidly increasing during last decades. Habitat fragmentation is one of the main threats to richness and diversity of wildlife. Ecological corridors can mitigate the loss and fragmentation of habitat. Corridors perform as “bridges” between habitats for species and they provide a flow of the natural or even anthropogenic caused disturbances. In this paper we will present the meaning and significance of ecological corridors in nature conservation, as well as types of ecological corridors and their ecological benefits. Methodological and practical approaches in nature protection system in Serbia are included. [Projekat Ministarstva nauke Republike Srbije, br. 47007 i br. 176008

On the entomofauna of Mt. Durmitor (Northern Montenegro): Braconid wasps of the subfamily Opiinae (Braconidae, Hymenoptera)

Braconids are primary parasites of other insects and their eggs, larvae, and adults, and species have been recently discovered that lay their eggs in plant seeds. Classified into about 25 genera, more than 1,400 species of Opiinae are known at the present time in the world fauna. They have been registered in all zoogeographic regions. The Opiinae are solitary endoparasites of the larvae of cyclorhaphous Diptera, most often those of species belonging to the families Agromyzidae, Tephritidae, Anthomyiidae Ephydridae. In investigations conducted on Mt. Durmitor since 1982, we have up to now established 10 species of braconids of the subfamily Opiinae (Opius peterseni Fi., O. caudatus Wesm., O. parvungula Th., O. levisWesm., O. pallipesWesm., O. quasiquisti Fi., O. exilis Hal., O. filicornis Th., O. lugens Hal., and O. meracus Fi), eight of which are new for the fauna of Serbia and Montenegro

A new species of Leonhardia Reitter, 1901 (Coleoptera, Leiodidae, Leptodirini) from Bosnia and Herzegovina, with a key to species of the genus

A new leptodirine leiodid beetle species belonging to the genus Leonhardia Reitter, 1901, L. solaki sp. nov., from a pit in Bosnia and Herzegovina (western Balkan Peninsula) is described and diagnosed. Important morphological features of the new species are listed and photographed. The new species is endemic to the Dinarides of Bosnia and Herzegovina. A key for identification of species and subspecies of the genus Leonhardia is also provided

DIPHYUS QUADRIPUNCTORIUS (MÜLLER, 1776) (HYMENOPTERA: ICHNEUMONIDAE: ICHNEUMONINAE): THE FIRST RECORDS FROM SERBIAN CAVES

Here we present new findings of the hymenopteran Diphyus quadripunctorius (Müller, 1776) from three cave localities in Serbia. We examined a total of five overwintering female specimens collected during 2016, 2019 and 2020 in caves – Devojačka Pećina Cave, Sisevačka Pećina Cave in eastern Serbia and Ogorelička Pećina Cave in southeastern Serbia. Additionally, a short description of D. quadripunctorius females is provided. Its phenology, tentative host association and adaptations to cave life are also discussed
