Abstract

Bu çalışmada, örümceklerde üç familyadan altı örümceğin sitotaksonomik özellikleri bildirilmiştir. Familyalara göre hem erkek hemde dişilerin kromozom sayılar şöyledir: Gnaphosidae Zelotes petrensis (C. L. Koch, 1839) ♂ 11 X, Zelotes aeneus (Simon, 1878) ♂ 9 XX, Nomisia conigera (Spassky, 1941) ♂ 10 XX; Theridiidae Theridion pictum (Walckenaer, 1802) ♀ 11 X, T. pictum ♂ 14 X, Steotoda triangulosa (Walckenaer, 1802) ♂ 12 XX; Lycosidae Trachosa ruricula (De Geer, 1778) ♂ 9 XX. Staetoda triangulosa hariç diğer türlerde karyolojik sonuçlar bu çalışma ile ilk kez gösterilmiştir. Çalışalan türlerin hepisinde kromozomların uzunlukları 2 µm daha kısa olduğundan bu kromozomların ölçüleri verilememiştir.

Abstract

In this study, six species of spiders in three families were reported cytotaxonomical properties. Chromosome accounts for both males and females (2n) on families: Gnaphosidae Zelotes petrensis (C. L. Koch, 1839) ♂ 11 X, Zelotes aeneus (Simon, 1878) ♂ 9 XX, Nomisia conigera (Spassky, 1941) ♂ 10 XX; Theridiidae Theridion pictum (Walckenaer, 1802) ♀ 11 X, T. pictum ♂ 14 X, Steotoda triangulosa (Walckenaer, 1802) ♂ 12 XX; Lycosidae Trachosa ruricula (De Geer, 1778) ♂ 9 XX. All karyologic results shown in this work the first time except to Staetoda triangulosa.All of the speciess, we studied of total lenght of chromosomes, is less than 2 µm. Therefore, the measurements of chromosomes were not made.
