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. [Projekat Ministarstva nauke Republike Srbije, br. 173038
