Abstracts

EN

Six species from six genera of the Oxycareninae were investigated.Males of all examinated species have 2 elongate follicles in each of the paired testes and an unpaired branched mesadenial gland.Four of them hsve 14 autosomes in the set.Two other pecies have 12 autosomes, one autosomal pair being larger than the others.The last two genera are monotypic and have similar morphological characters.In all the examined species there is a pair of m-chromosomes, situated separately or as a pseudobivalent during mataphase 1 of meiosis, found in all the investigated cells near to the sex (XY) chromosomes.
