Only two species of Chthonius (Ephippiochthonius) (Chthoniidae) are presently known from Dobruja, Romania. Among these one should mention Chthonius (Ephippiochthonius) tetrachelatus (Preyssler) (not endemic) and C. (E.) scythicus Georgescu & Cãpuşe (endemic). A new cave species belonging to the genus Chthonius - Chthonius (Ephippiochthonius) borissketi Ćurčić and Sarbu n. sp., is described from a well nr. Movile Cave, Mangalia, Romania and is endemic to the area studied. Its taxonomic relationships with phenetically close congeners, as well as its comparative morphological traits, are described in detail. [Projekat Ministarstva nauke Republike Srbije, br. 173038]

GIS is a computer-based system to input, store, manipulate, analyze and output spatially referenced data. There is a huge range application of GIS that generally sets out to fulfill: mapping, measurement, monitoring, modeling and management. In this study, GIS technology was used for the regional recognition of origin and distribution patterns of multifloral honey chemical traits in Serbia. This included organizing and analyzing the spatial and attributive data of 164 honey samples collected from different regions of Serbia during the harvesting season of 2009. Multifloral honey was characterized in regards to mineral composition, sugar content and basic physicochemical properties. The kriging method of Geostatistical Analyst was used for interpolation to predict values of a sampled variable over the whole territory of Serbia. [Projekat Ministarstva nauke Republike Srbije, br.

A complex mixture of compounds was identified from the secretion of specimens of Unciger transsilvanicus. Phenol and p-cresol were detected for the first time in the family Julidae, and for the second time in the order Julida. Thirteen quinones were identified, with a great relative abundance of toloquinone and 2-methoxy-3-methyl-1,4-benzoquinone. Hydroquinone was detected for the first time in the order Julida. Besides these compounds, isopentyl hexacosatetraenoate and isopentyl esters of saturated and unsaturated fatty acids with chain lengths from C14 to C20were identified. The most abundant non-quinone compound was isopentyl eicosenoate. The relative abundance of quinone and non-quinone in the defensive fluid of U. transsilvanicus was 77% and 23%, respectively. The phylogenetic importance of the registered compounds is briefly discussed. [Projekat Ministarstva nauke Republike Srbije, br. 173038 i br. 172053]

A new blind false scorpion, Microchthonius kasteli n. sp., from the Mićoletova Jama Pit, Rudine, nr. Kaštel, Dalmatia, has been described. The new pseudoscorpion is different from all other congeners. It is probable that this new taxon is the remain of an old tropical soil fauna, which now inhabits the subtropical area of the Mediterranean seaside. Morphometric ratios, figures, and linear measurements of the new species are presented in detail. [Projekat Ministarstva nauke Republike Srbije, br. 173038]

[Projekat Ministarstva nauke Republike Srbije, br. 173038]

The cave-dwelling forms of the genus Neobisium L. koch comprise many phyletic lines, some less specialized and others highly adapted to cave life. To trace their origin, biogeography and evolution, it is necessary to compare the evidence about troglobitic species with that of the epigean forms from different European habitats, especially in the Mediterranean or Dinaric regions. In this study, descriptions of Neobisium crucis n. sp. and N. pluzinensis n. sp., both from caves in Montenegro, are presented, with some details on the comparative morphology and morphometric ratios.

Five years ago, Ćurčić et al. (2008) described two new pseudoscorpions: Roncus diocletiani Ćurčić, Dimitrijević and Rađa (from Croatia) and R. orjensis Ćurčić, Dimitrijević and Rađa (from Montenegro). The pseudoscorpions studied were mounted on slides with gum-chloral medium. They are deposited in the collection of the Institute of Zoology, Faculty of Biology, University of Belgrade, 11000 Belgrade, Serbia and in the collection of the Natural History Museum, 21000 Split, Croatia. It has been shown that only the male of R. diocletiani belongs to the nominal species, while the female of the same taxon belongs to Archaeoroncus tenuis (Hadži). Therefore, the “allotype male” of R. diocletiani is actually a holotype of this species, while the “holotype” of R. diocletiani becomes a paratype of A. tenuis.

Two species of troglobitic false scorpions, Roncus meledae n. sp. and Neobisium oculatum n. sp. (Neobisiidae, Pseudoscorpiones), are described from inside underground habitat, i.e. the Jama Na Žutim Kokom Cave, the Island of Mljet, Dalmatia, Croatia. The analyzed pseudoscorpions prove to differ from all other congeners. It is possible that the subterranean pseudoscorpions analyzed represent relicts of an old north tropical faunal pattern of the Mediterranean.

Parental care in the geographically widespread cryptopid scolopendromorph Cryptops hortensis (Donovan) is described for the first time. It was observed that the adult female rolls her body around the mass of hatchlings with the ventral side against the brood. This finding supports the hypothesis that within the brooding centipedes, the female position with the terga outwards is a plesiomorphic state and probably a general feature of all Scolopendromorpha. In addition, the major external morphological characters of the fetus instar and adolescens I are described.

A new genus (Punctoduvalius gen. n.) and a species of trechine ground beetles (Punctoduvalius orlovacensis sp. n.) from Bosnia and Herzegovina have been described and diagnosed. Punctoduvalius gen. n. is clearly distinct from all other phenetically close genera in many important respects, such as: the presence of depigmented reduced eyes, the presence of a pigmented eye border, the presence of deep and complete frontal furrows, the presence of tiny setae on the genae, the presence of distinct longitudinal fissures on the protibias, the ratio of length/width of the first protarsal article in males, the presence of two elytral discal setae, the presence of numerous setiferous punctures in interstrial spaces, the specific position of the humeral setae, and the specific shape of the copulatory piece. This new genus comprises four species: Punctoduvalius pilifer (Ganglbauer, 1891) (endogean from Mts. Treskavica and Bjelašnica, and from a cave on Mt. Visočica, Bosnia and Herzegovina), P. protectus (Winkler, 1926) (from the Pećina kod Ostojića Cave, Mt. Treskavica, and endogean from Mt. Jahorina, Bosnia and Herzegovina), P. brevipilosus (Knirsch, 1927) (endogean from Lupoglav Peak, Mt. Prenj, Bosnia and Herzegovina), and P. orlovacensis sp. n. (from the Orlovača Cave, village of Donje Biševo, near Pale, Bosnia and Herzegovina). The four species clearly differ in many important respects. The following three taxonomic changes are proposed: Punctoduvalius pilifer (Ganglbauer, 1891), comb. n., P. protectus (Winkler, 1926), comb. n., and P. brevipilosus (Knirsch, 1927), comb. n. The new genus and its members belong to an old separate phyletic lineage, distinct from all other existing species groups. Additionally, these forms are relict and endemic to the deep soil and caves of Bosnia and Herzegovina. [Acknowledgments.

A new leptodirine leiodid beetle species, Parapropus vitorogensis sp. n., from a cave in the western part of the Republic of Srpska, Bosnia and Herzegovina, is described and diagnosed. Both male and female genitalia and other taxonomically important characters are illustrated. The new species is clearly distinct from its closest congeners. The new taxon is of Tertiary or even pre-Tertiary age and originated during the Alpine Orogeny that affected vast areas of the Balkan Peninsula, including the Dinarides, its terra typica. The new species is both endemic and relict, inhabiting western Bosnia and Herzegovina only. [Projekat Ministarstva nauke Republike Srbije, br. 173038 and br. 47007]

A new genus and species of Anthroleucosomatidae is described from Serbia. Dazbogosoma naissi n. g. n. sp. is characterized by the presence of few ocellae, apically bifurcated syncoxite, and the presence of complex lateral parts of anterior gonopods with truncated process. The new genus belongs to the Bulgarosoma complex of genera that probably deserve a suprageneric level.

A new species of the pseudoscorpion genus Roncus L. Koch (Neobisiidae) from Serbia (Kulina, Mt. Medvednik) is described and its diagnostic characters are illustrated. Interrelations with phenetically close congeners are analyzed; in addition, the presence/absence of microsetae proximal to the trichobothria eb and esb and presence/absence of one or two outstanding tubercles on the interior lateral side of pedipalpal femur are established as important taxonomic characters.

A new endemic epigean species from the village of Adžina Livada, nr. Kragujevac, Mts. Gledićke Planine, western Serbia, is erected, described and thoroughly illustrated.

Ćurčić from western Serbia, respectively.

The pseudoscorpion sample from a cave in Bosnia has been studied. Two new species have been described herein: Chthonius (Chthonius) protobosniacus n. sp. and C. (C.) kladanjensis n. sp. Both taxa are considered endemic of Bosnia and the Balkan Peninsula. In this paper, diagnostic characters of the analyzed forms are thoroughly described and figured. Taxonomic interrelationship amd geographic distribution are briefly discussed.

The pseudoscorpion sample from a cave in Montenegro has been studied. A new species, Chthonius (Globochthonius) medeonis n. sp. is described. A reanalysis of the type material of Chthonius (Ephippiochthonius) polychaetus Hadži supports its transfer to the subgenus Chthonius (Globochthonius Beier). The species studied is considered to be endemic to the Balkan Peninsula. The diagnostic characteristics of the analyzed taxon are thoroughly described or figured. Taxonomic interrelationships and geographic distribution are briefly discussed.

A new species of epigean pseudoscorpion pertaining to the genus Chthonius C. L. Koch 1843 from Macedonia is erected. Its relationship to phenetically close congeners is briefly discussed. The new species, Chthonius (Ephippiochthonius) lagadini n. sp. is a relict form presently known only from its type locality (Lagadin, nr. Ohrid, Macedonia).

We describe and analyze two examples of naturally occurring morphological anomalies in the geophilomorph centipedes. Recorded abnormalities include a supernumerary hemisclerite in an adult female specimen of Clinopodes flavidus C.L. Koch, and an even number of leg-bearing segments in a subadult male specimen of Clinopodes trebevicensis (Verhoeff). The morphological complexity of these defects makes them hard to explain as the result of healing or regeneration. They are most probably congenital and are interpreted as the effects of perturbation of different morphogenetic processes occurring at different phases of development of the segments in a given trunk region.

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).

A new pseudoscorpion from the family Chthoniidae - Chthonius (Chthonius) aquasanctae n. sp. from west Serbia is described. The newly erected taxon is endemic to the area studied.

A new cave-dwelling pseudoscorpion from the Badanj (or Vilišnica) Cave, nr. Sveti Filip i Jakov, Dalmatia (Croatia) is thoroughly described and illustrated. Its main morphometric characteristics and important diagnostic traits are analyzed and compared to those of its phenetically close congener Chthonius (Chthonius) absoloni Beier from Dalmatia. The new species is relict and endemic to the area studied.

Two new epigean pseudoscorpion species belonging to the family Chthoniidae - Chthonius (Ephippiochthonius) metohicus n. sp. and Chthonius (Ephippiochthonius) civitatisveti n. sp. from the UN Administered Province of Kosovo and Southern Croatia, respectively, are described. The newly erected taxa are endemic to each of the areas studied. Their taxonomic relationship with their phenetically close congeners Chthonius (Ephippiochthonius) bidentatus Beier, 1939, Chthonius (Ephippiochthonius) kemza Ćurčić, Lee et Makarov, 1993 and Chthonius (Ephippiochthonius) tetrachelatus (Preyssler, 1790) and comparative morphological traits are described.

Two new endemic cave pseudoscorpion species from the Petropavlova Pećina Cave, village Bihovi, 6 km from Trebinje, Herzegovina, are presented, thoroughly described and illustrated. These are named Chthonius (Globochthonius) petroupauli n. sp. and Roncus paulipetrou n. sp. Their main morphometric characteristics and important diagnostic features are analyzed and compared to those of their phylogenetically closest congeners.

We have analyzed and discussed the indirect evidence of regeneration of the forcipular telopodites and the walking legs (reduced in size or abnormal characteristics such as atypical morphology and a reduced number of articles) in wild populations of the lithobiomorph centipede Eupolybothrus transsylvanicus (Latzel). In our opinion, these morphological defects can be interpreted as a result of incomplete regeneration. In some cases, the full segmentation of the regenerating appendages will be completed later in ontogeny through an anamorphic schedule of post-embryonic segment addition.

Two species of pseudoscorpions new to science (Neobisium montisageli n. sp. and Roncus peissei n. sp.), collected in Southeastern France, are described, the diagnostic characteristics are illustrated, and their distribution is given. The possible establishment of two species groups of Roncus in Europe is discussed briefly in view of the importance of some of the diagnostic characteristics. .

A new endemic cave-dwelling pseudoscorpion species from the Seselačka Pećina Cave, village Seselac, nr. Soko Banja, East Serbia is presented, described and illustrated. Its main morphometric characteristics and important diagnostic features are analyzed and compared to those of its closest congener Neobisium carpaticum (Beier, 1930) from Serbia.

Most subterranean pseudoscorpions are concentrated in regions with a Mediterranean climate. Although data on the abundance of pseudoscorpion species in the humid tropics are lacking, preliminary observations suggest that the number of species is greater in the Mediterranean area than in tropical rain forests. Speciation in pseudoscorpions has not been studied in great detail. New taxa are constantly being described. Exact data on the different niche preferences which are a prerequisite for evolutionary studies are available for only a few cases. The pseudoscorpions are not particularly suitable for genetic investigations due to their extended generation times. The cave-dwelling forms of the genus Neobisium L. Koch comprise many phyletic lines, some less specialized and others highly adapted to cave life. To trace their origin, biogeography and evolution, it is necessary to compare the evidence about troglobitic species with that of the epigean forms from different European habitats, especially in the Mediterranean or Dinaric regions. To the south of the river Zrmanja, up to the lower Neretva valley, a massive Holokarst region rises to a considerably height. Many summits attain between 1800 and 2000 m, and Mt. Dinara gave its name to both the Dinaric region and the Dinaric Karst. The karst of Mt. Mosor (and Mts. Kozjak and Biokovo), is quite different from that previously discussed. This is a zone of younger, intensively folded mountains. Their karst, although young, appears to be deep and almost fully developed. In this study, descriptions of Neobisium montdori n. sp., N. mosorensis n. sp., and N. dalmatinum Beier, 1939, all from caves on Mt. Mosor, Dalmatia (Croatia), have been presented, with some details on the comparative morphology of both sexes and tritonymph.

Three new species of the pseudoscorpion genus Roncus L. Koch (Neobisiidae) are described from Croatia (from nr. Omiš, Dalmatia: R. almissae n. sp.) and Serbia (near the town of Krupanj, north-western Serbia, Lukića Pećina Cave and nr. Izvor: R. krupanjensis n. sp., and R. radji n. sp.), and their diagnostic characteristics are illustrated. Their interrelations with phenetically close congeners are analyzed; in addition, the presence/absence of microsetae proximal to the trichobothria eb and esb is established as an important taxonomic characteristic.

A new epigean pseudoscorpion, Chthonius (Chthonius) onaei n. sp. is erected from Podašpilje, nr. Omiš, Mt. Omiška Dinara, Dalmatia, Croatia. Its interrelations with two close congeners, Chthonius (C.) litoralis Hadži, 1933 and Chthonius (C.) dalmatinus Hadži, 1930 are briefly discussed.
