Morphological investigation of reproductive systems in the female individuals of some araneae species showing in Kastamonu province

Spider morphology and reproductive systems differ from other arachnid groups. With the help of pedipalps similar to walking legs, sperm transfer is made from male to female. Depending on the epigin structure of the female spider, this transfer can take different forms.Fertilization varies in entelegyne and haplogyne type epigins. Haplogyne-type epigins have a simple structure while entelegyne-type epigins have a more complex structure. Spider genital structures show key-lock compatibility to prevent hybrid species formations. Spiders recognize individuals of their own kind with a set of vibration and courtship dances. Spiders have sexual dimorphism. The female individual is much larger than the male individual. In this thesis, the morphological examination of the reproductive systems in female individuals of some arenae species spread in Kastamonu province was made. It has been observed that the spider reproductive structures collected in the images are different in all types.
