Two new species of the genus Isotomiella Bagnall, 1939 are described and illustrated, the first: Isotomiella macedoisp. n., based on males and females, from the "Parque Nacional da Serra dos Órgãos" (Teresópolis municipality, State of Rio de Janeiro) differs from the other by tibiotarsus III thickened and blunt and two antero-lateral chaetae of labrum strongly thickened. The second species Isot...

in order to investigation of collembola fauna, several soil and leaf litter sampling were carried out during 2011 in kermanshah regions and species were extracted by berlise funnel. in sum, eight species from eight genera from seven families were collected and identified. the species characterized by one star (*) are new for kermanshah fauna. the species characterized by two star (**) are repor...

The present paper describes Paracerura gandarela sp. nov.based on material from the Serra do Gandarela Mts., Municipality of Caeté, State of Minas Gerais. The new species is the sixth of the Neotropical genus Paracerura Deharveng & Oliveira, 1994 with distribution limited to Brazil. P. gandarela sp. nov. differs from other congeners especially by sensillary set on abdominal segments IV-V and ch...

Drought tolerance (survival at 98.2% relative humidity and 20 degress C) was investigated for adult individuals of the springtail Folsomia fimetaria after three weeks of exposure to different polycyclic aromatic compounds (PACs). Seven PACs were investigated (acridine, dibenzofuran, carbazole, fluorene, dibenzothiophene, fluoranthene, and pyrene), with each substance used at several exposure co...

Parisotoma notabilis is the most common species of Collembola in Europe and is currently designated as ubiquist. This species has been extensively used in numerous studies and is considered as well characterized on a morphological ground. Despite the homogeneity of its morphology, the sequencing of the barcoding fragment (5' end of COI) for several populations throughout Europe and North Americ...
