The family of the Antroleucosomidae is known from the Mediterranean region. In this paper the author describes the new genus Dacosoma with the species D. motasi of caves of the southern Carpathians together with two new species of Bulgarosoma, B. Ocellatum n. sp. of the caves of Mount Banat and B. meridionalis of the cave on Rhodope mountains. A new and complete description is also given for Antroleucosoma banaticum Verh. 1899 and B. bureschi Verh. 1926 based on the study of material coming from the type localities.

A cavernicolous pseudoscorpion of the genus Neobisium Chamberlin 1930 is living in Kalina Dupka cave in the Bistra Highland of western Macedonia. This pseudoscorpion clearly differs from the other members of the subgenus Blothrus Schiodte 1849, and belongs to the new species N. (B.) princeps, the principal features of which are described in this study. The nearest relatives of this species are N. (B.} spelaeum (Schiodte) 1849, and N. (B.) stygium Beier 1931, both from Slovenian and Croatian caves. From chelal dentition N. (B.) princeps may be considered as the most primitive element of the princeps-stygium-spelaeum series. This new species is in a subterranean mode of life of extreme specialization. Relating to biogeography, it belongs to the endemic pseudoscorpion fauna in Macedonia. After finding pseudoscorpions in Zmejovica cave (Porece mountainous area), we confirmed the presence of the species N. (E.) karamani (Hadli) 1929 in west Macedonia. Morphologic analysis of male specimens from that new locality enabled us to complete description of this species previously based on a single female specimen. The comparison of Hadzi’s species with N. (E.) remyi Beier 1939 from west Serbian caves, with N. (E.) brevipes (Frivaldsky) 1866 and N. (E.) leruthi Beier 1931 from Turda and Bihar caves in southern Carpathians, leads to the conclusion that these pseudoscorpions belong to a closely related species group. Judging by actual distribution of these species, the possibility exists that a wide area in the ancient Balkanic dry land had been populated by the initial form of that series. As for its preferences for habitat N. (E.) karamani is an exclusive inhabitant of subterranean environment. Relating to biogeography, it may be considered as a relic of Mediterranean Tertiary fauna and its endemic differentiation as developed under the conditions of the evolution of karst relief in southern countries of the Balkan Peninsula. In conclusion, from actual knowledge and the results of this study caves in Macedonia are inhabited by three endemic species of pseudoscorpions of genus Neobisium (Blothrus), namely: N.(B.) ohridanum Hadzi 1940,N. (B.) karamani (Hadzi) 1929, and N. (B.) princeps Curcic 1974. Judging by known blothroid pseudoscorpions, it is possible Macedonia represents one of the centres of origin and genesis for autochthonous and residual fauna of the Tertiary age.
The paper is a geomorphological classification of pseudokarst forms in Czechoslovakia/Bohemien Massif and the Carpathians. In the author's opinion, forms occurring in non-carbonate rocks, are morphologically and often genetically analogous to the forms of karst relief, and are pseudokarst phenomena. They are divided according to their size into macroforms in sandstone morphostructures of the Bohemian Cretaceous Basin some types of rocky valleys, water-shed plains and ridges, forming rock cities in some places, mesoforms with six types of caves, sinkholes, rock perforations and several rock phenomena and microforms such as weather pits and niches, lapies, etc.. The most prominent pseudokarst phenomena have been formed in the sandstones of the Bohemian Cretaceous Basin whose relief may be considered "pseudokarst". They are also common in other sediments; in neovolcanic rocks and granitic rocks, as well as in other types of rocks. Pseudokarst forms are the product of geomorphological processes, especially weathering and denudation, block rock slides, erosion, suffosion, etc. Most of them have been developing in the recent mild humid climatic conditions.
The Silica nappe (s.l.) of the Inner West Carpathians consists of an essentially non-metamorphic, platform-type sedimentary complex of Mesozoic (chiefly Triassic) age. Palaeomagnetic samples were collected from 16 sites throughout the southern and northern Gemeric parts of this unit and from one site of the Mesozoic Meliata series which underlies the Silica nappe (s.s.) in south Gemer. The samples from each site were treated using thermal demagnetization and well-grouped magnetic directions of individual components were found for 13 (14) sites. Detailed analysis of the directional data showed (a) post-folding magnetization for four late Triassic-Jurassic sites in the eastern Slovak Karst, (b) synfolding magnetization for five sites in the western Slovak Karst with a direction corresponding to local palaeomagnetic data of African affinity for the late Cretaceous and (c) primary magnetizations in the northern Gemeric area for only two rock units with a declination difference which implies a relative rotation between these units. As all secondary remanences are of normal polarity it is very likely that their acquisition is related to the emplacement of the Silica nappe during the early late Cretaceous. The dominant remagnetization mechanism probably is CRM but occasional contributions of TVRM are also conceivable
At Tylicz, near Krynica Spa (Polish Carpathians), spelean deposits fill fissures and caverns in Eocene flysch rocks. They occur as: (1) clastic cave sediments transformed into hard crusts due to cementation by finely crystalline low-Mg calcite, (2) drusy calcite that covers crust surfaces and fills voids in the crust and (3) colloform calcite. Two varieties of drusy calcite are distinguished: acicular and columnar. The acicular calcite is built up of crystallites forming spherulitic fans or cones. In places it is syntaxially covered with colloform calcite. The drusy calcite is low-Mg ferroan calcite with non-ferroan subzones, whereas the colloform calcite is a low-Mg non-ferroan variety. The columnar calcite crystals form fan-like bundles. Cross-sections cut perpendicular to the c-axes of columnar crystals are equilateral triangular in shape, although some have slightly curved edges. The columnar crystals have steep rhombic terminations and most have curved triangular faces, i.e. gothic-arch calcite. Saddle crystals have also been observed. The columnar crystals are composed of radially orientated crystallites whose long dimension is parallel to the c-axis. The curved crystal faces of such polycrystals are interpreted as a result of differential growth rates of the crystallites. The spelean calcites precipitated from CO2-saturated water. The high rate of CaCO3 Precipitation is thought to be responsible for the formation of radial structures. Finely crystalline calcite formed within pore spaces of clastic sediments close to the water-air interface, drusy calcite crystallized beneath the water-air interface, and colloform calcite precipitated from thin films of water
The considerable areal extent and great thicknesses of Middle/Upper Triassic carbonate complexes influenced favourably the formation of karst during subaerial periods. The lower boundary of the Paleoalpine karst period is age-determined by the gradual emergence of the basement - during the Upper Cretaceous in the Central Western Carpathians and even earlier in the Inner Carpathians. The upper boundary can be dated by marine transgression The start of the transgression is not synchronous and it varies in a broad range from Upper Cretaceous to Upper Eocene and maybe even up to Oligocene/Miocene. The typical products of the period include typical karst bauxites filling karst cavities, ferri crusts, red clays, collapse and crackle breccias with speleothems, freshwater limestones or polymict conglomerates
The considerable areal extent and great thickness of Middle/Upper Triassic carbonate sequences favourably influenced the development of paleokarst during the Paleoalpine karst period in the Brezovske Karpaty Mts. Carbonate formations provide data concerning the first-pre-Gosau-phase of the Paleoalpine karst period. Freshwater limestones, bauxites, reddish ferrugineous silty clays, Valchov Conglomerate, shallow doline-like depressions and deeper canyon-like forms represent the most important pre-Gosau karst sediments and forms
Karst and non-karst regions in the territory of Slovakia are notable for a very broad typological range of caves. The criteria of cave genetic classification in the existing works concerning parts of the Western Carpathians are not integrated. We suggest fundamental principles of classification and charaterize the basic genetic types of caves in this paper. We also advert to several problems of karstological and speleological terminology (exokras and endokarst, karst and pseudokarst).
Ochtina Aragonite Cave is a 300 m long cryptokarstic cavity with simple linear sections linked to a geometrically irregular spongework labyrinth. The metalimestones, partly metasomatically altered to ankerite and siderite, occur as isolated lenses in insoluble rocks. Oxygen-enriched meteoric water seeping along the faults caused siderite/ankerite weathering and transformation to ochres that were later removed by mechanical erosion. Corrosion was enhanced by sulphide weathering of gangue minerals and by carbon dioxide released from decomposition of siderite/ankerite. The initial phreatic speleogens, older than 780 ka, were created by dissolution in density-derived convectional cellular circulation conditions of very slow flow. Thermohaline convection cells operating in the flooded cave might also have influenced its morphology. Later vadose corrosional events have altered the original form to a large extent. Water levels have fluctuated many times during its history as the cave filled during wet periods and then slowly drained. Mn-rich loams with Ni-bearing asbolane and bimessite were formed by microbial precipitation in the ponds remaining after the floods. Allophane was produced in the acidic environment of sulphide weathering. La-Nd-phosphate and REE enriched Mn-oxide precipitated on geochemical barriers in the asbolane layers. Ochres containing about 50 wt.% of water influence the cave microclimate and the precipitation of secondary aragonite. An oldest aragonite generation is preserved as corroded relics in ceiling niches truncated by corrosional bevels. Thermal ionisation mass spectrometry and alpha counting U series dating has yielded ages of about 500-450 and 138-121 ka, indicating that there have been several episodes of deposition, occurring during Quaternary warm periods (Elsterian 1/2, Eemian). Spiral and acicular forms representing a second generation began to be deposited in Late Glacial (14 ka - Allerod) times. The youngest aragonite, frostwork, continues to be deposited today. Both of the, younger generations have similar isotopic compositions, indicating that they originated in conditions very similar, or identical, to those found at present in the cave
The most well developed karstic forms in the whole of the Carpathians emerged in the Transylvanian Mountains (Mt. Apuseni) situated between the Transylvanian basin and the Great Hungarian Plain. This phenomena correlates with the diversity of structure and rock formation, and to the multifold nature of denudation processes. My intention is to present a survey and morphogenetic systematization of the most interesting karstic regions.
