Abstract :

Spiders (Araneae) appear to be the best studied order, of the class Arachnida concerning Chromosomal aspects. They exhibit great diversity in diploid chromosome numbers. Compared with others Araneidae spiders, chromosomes of the Araneae: spider are less studied. In this study, chromosomes of two Araneidae spiders Cyrtophora citricola (Forskål, 1775) and Neoscona theisi (Walckenaer, 1841) were observed and studied based on the samples collected from Akola region. The chromosome diploid number and the sex chromosomal system in both the spider species found 2n=(22+X1X1X2X2) and 2n=(22+X1X2) respectively. Both the spider species shows telocentric chromosomes.
