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

On the identity of types of Roncus diocletiani Ćurčić, Dimitrijević & Rađa and Archaeoroncus tenuis (Hadži) (Pseudoscorpiones, Neobisiidae) from Croatia

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.

A new Pseudoscorpion from Bosnia: Roncus bosniensis n. sp. (Neobisiidae, Pseudoscorpiones)

A new species of troglobitic false scorpion, Roncus bosniensis n. sp. (Neobisiidae, Pseudoscorpiones), is described from inside an underground habitat, the Jama Pored Puta Pit, nr. Jajce, Bosnia and Herzegovina. The analyzed pseudoscorpion proves to differ from all other congeners, but is closest to R. hajnehaj Ćurčić & Dimitrijević. It is possible that the subterranean pseudoscorpion analyzed represents a relict of an old tropical faunal pattern of the Mediterranean. [Projekat Ministarstva nauke Republike Srbije, br. 173038

On the appendage regeneration of Eupolybothrus transsylvanicus (Latzel) (Chilopoda: Lithobiidae)

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

Roncus meledae n.sp. and Neobisium oculatum n.sp., from the island of Mljet, Dalmatia (Neobisiidae, Pseudoscorpiones)

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.

On two new cave-dwelling and relict pseudoscorpions of the genus Chthonius C.L. Koch (Chthoniidae, Pseudoscorpiones) from Bosnia

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

Neobisium crucis n. sp. and N. pluzinensis n. sp., two new cave-dwellers from Montenegro (Neobisiidae, Pseudoscorpiones)

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.

Chthonius (Ephippiochthonius) lagadini n.sp. (Chthoniidae, Pseudoscorpiones), a new endemic epigean pseudoscorpion from Macedonia

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)

Microchthonius kasteli n. sp. (Chthoniidae, Pseudoscorpiones): A new cave false scorpion from Croatia (Dalmatia)

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

A new epigean false scorpion: Roncus sumadijae n.sp. (Neobisiidae, Pseudoscorpiones) from the Balkan Peninsula (Western Serbia)

A new endemic epigean species from the village of Adžina Livada, nr. Kragujevac, Mts. Gledićke Planine, western Serbia, is erected, described and thoroughly illustrated. Its main morphometric characters and important diagnostic features are analyzed and compared to the two closest congeners, Roncus ivanjicae B. Ćurčić, and R. golijae B. Ćurčić from western Serbia, respectively
