A New Diploid Number and Sex Chromosome System for the Family Hersiliidae from the Mediterranean Region of Turkey

ABSTRACT
Cytogenetic features, mitotic metaphase chromosomes, karyogram and course of meiosis of Hersiliola bayrami were determined based on Giemsa-stained testicular chromosomes for the first time. Results of spermatogonial metaphases showed that the chromosome number and the karyotype formula of the species was 2n♂=35 (X1X2X30) which is the first record for the family Hersiliidae. Both autosomes and sex chromosomes were acrocentric. The lengths of the chromosomes indicated no significant difference between autosomal pairs, however, X3 was the smallest chromosome but X1 and X2 were intermediate in the karyotype.
