A contribution to the knowledge of the species Rafalskia olympica (KULCZYNSKI, 1903) (Opiliones, Phalangiidae, Phalangiinae)

Balkan populations of Rafalskia olympica (KULCZYNSKI, 1903) are distinguished as separate subspecies Rafalskia olympica bulgarica ST ARI::GA, 1963 novo stat. Certain novel details of the R. olympica female body structure are presented. It is stated that Metaplatybunus drenskii SILHAVY, 1965 is not a synonym of R. olympica

Nova troglobiontska vrsta Alpioniscus (Illyrionethes) iapodicus n. sp. (Crustacea: Oniscidea: Trichoniscidae) iz Like (Hrvatska)

Alpioniscus (Illyrionethes) iapodicus n. sp. is described and illustrated. Representing the 14th nominal species of the subgenus Illyrionethes from the Dinaric karst, it is a troglobiotic species collected from the caves in the central part of the Lika region, Croatia. The new species belongs to the strasseri group. Morphological characters differentiating A. iapodicus from other strasseri group representatives are discussed.U radu se opisuje i ilustrira nova vrsta Alpioniscus (Illyrionethes) iapodicus n. sp. Radi se o troglobiontnoj vrsti prikupljenoj u špiljama središnjeg dijela Like, i predstavlja četrnaestu nominalnu vrstu podroda Illyrionethes iz Dinarskog krša. Nova vrsta pripada grupi strasseri. Raspravlja se o morfološkim obilježjima koji razlikuju A. iapodicus od ostalih predstavnika te grupe

Parasironidae fam. nov., a Cimmerian lineage of Mediterranean Cyphophthalmi (Opiliones), with the description of three new genera and four new species

A new family of Cyphophthalmi with disjunct Mediterranean distribution, Parasironidae fam. nov., is proposed. The new family comprises four genera and seven species. Cimmerosiro gen. nov., Tirrenosiro gen. nov. and Ebrosiro gen. nov. are described as new genera, and Tirrenosiro axeli gen. et sp. nov., Cimmerosiro krivolutskyi gen. et sp. nov., C. juberthiei gen. et sp. nov. and C. rhodiensis gen. et sp. nov. as new species. Parasironidae stands out by a set of characteristics that we recognize as predominantly plesiomorphic. These characteristics and the present distribution indicate the great age of the family, probably early Mesosoic. We attribute its origin to the western part of the Cimmerian terrane, and its current distribution and diversification of the major clades to geotectonic events during the Mesozoic. Additionally, a new sensory organ (sensilla) has been discovered in Cyphophthalmi. This organ is located on the pedipalp coxae and is believed to have a potential hygroreceptive function

In vitro Radioprotective Activity of the Bryozoan Hyalinella punctata

The objective of the present study was in vitro evaluation of radioprotective activity of the freshwater bryozoan Hyalinella punctata on cultured human peripheral blood lymphocytes after irradiation with 2 gy of Co-60 gamma-rays. Since its water extract at concentration 0.001 mg/mL reduced the incidence of radiation-induced micronuclei for almost 30 %, it could be considered as a promising source of new natural products with the aforementined activity. Both the content of sulphur (1.17%) determined by gravimetric method and infrared absorption frequences (76 % similarity with those of bacitracin) of the investigated extract indicate the presence of organic sulphur compound(s) such as cyclic peptides and polypeptides which might be responsible for the observed radioprotectio

Antimicrobial Activity of the Freshwater Bryozoan Hyalinella Punctata (Hancock, 1850)

The antimicrobial activity of the freshwater bryozoan Hyalinella punctata (Hancock, 1850) was tested by microdilution method against eight bacteria and eight fungi for the first time. All five crude extracts (hexane, acetone, dimethyl sulfoxide, methanol and water) showed good antibacterial and antifungal potential in vitro wherein the acetone extract was the most active (MICs 0.50-7.00 mu g/ml and MBCs 2.50-10.00 mu g/ml).Ministry of Science and Technological Development of the Republic of Serbia [173040, 173032, 173017, 172053, III43007
