Karyotypes of six spider species belonging to the families Gnaphosidae, Salticidae, Thomisidae, and Zodariidae (Araneae) from Turkey

Abstract. In this study, the karyotypes of six spider species from Turkey belonging to the families Gnaphosidae, Salticidae, Thomisidae, and Zodariidae were analyzed. Male chromosomal features including diploid chromosome numbers and sex chromosome systems were determined as 2n=22, X(1)X(2)0 in Drassyllus sur Tuneva & Esyunin, 2003, Nomisia exornata (C. L. Koch, 1839), and Nomisia orientalis Dalmas, 1921; 2n=28, X(1)X(2)0 in Sitticus caricis (Westring, 1861); 2n=23, X0 in Xysticus gallicus Simon, 1875 and 2n=42, X(1)X(2)0 in Pax islamita (Simon, 1873), respectively. The chromosome morphology of all species was acrocentric. Data obtained contribute to knowledge of the karyotype evolution of araneomorphs.
