Özet:

 Wagners gerbil, Gerbillus dasyurus, is present in Middle East, Arabian Peninsula and marginally into eastern desert of Egypt. The only records have been taken from Kilis in Turkey. In the present study, 10 specimens were collected from three localities in the Hatay Province. These specimens were captured in rocky hills and slopes with poor soil and vegetation on blocky igneous rocks, and also in the rocky lava flow area in the north eastern part of the Hatay Province. Diploid number of chromosome, number of chromosomes and fundamental number of autosomal arms of the specimens was found as 2n  60, NF  70 and NFa  66, respectively. The relative abundance of species was estimated to be 2.74. The mean of the entire baculum is 2.37 mm long, and 0.52 mm the maximum wide n3. Number of roots on molars: 3 M1 and M2, 2 M1 and M2 and, 1 M3 and M3. The tail lenght is markedly longer than the total legnth of head and body. Morphological and karyologic characters of the samples verify that the indivuduals investigated belongs to Gerbillus dasyurus. However, it is possible to show inter- and intrapopulational variations because of the differences seen in the root number of M1, the proportion of the tail, and the shape of baculum etc., through a detailed study that covers all distribution area. This record is the second record of the species from Turkey. Since no examples could be obtained in the later studies in Kilis region, which was the first record locality, the protection of the new record localities in Hatay is important for the survival of the species in Turkey.

 Kayalık gerbili, Gerbillus dasyurus, Orta Doğuda, Arap Yarımadasında ve marjinal olarak Mısırın doğu çölünde bulunur. Türkiyedeki tek kayıt Kilisten alınmıştır. Bu çalışmada Hatay ilindeki üç lokaliteden 10 örnek toplanmıştır. Bu örnekler, Hatay İlinin kuzeydoğu kesimindeki kayalık lav akıntısı alanında ve bloklu magmatik kayalar üzerinde toprak ve bitki örtüsünün zayıf olduğu kayalık tepeler ve yamaçlardan yakalanmıştır. Örneklerin diploid kromozom sayısı, kromozom kol sayısı ve temel otozomal kol sayısı sırasıyla 2n  60, NF  70 ve NFa  66 olarak bulundu. Türlerin nispi bolluğu 2,74 olarak tahmin edilmiştir. Tüm baculumun ortalaması 2,37 mm uzunluğunda ve 0,52 mm maksimum genişliktedir n3. Azı dişlerindeki kök sayısı: 3 M1 ve M2, 2 M1 ve M2 ve 1 M3 ve M3. Kuyruk uzunluğu, baş ve gövdenin toplam uzunluğundan belirgin şekilde daha uzundur. Örneklerin morfolojik ve karyolojik özellikleri, incelenen bireylerin Gerbillus dasyurusa ait olduğunu doğrulamaktadır. Ancak M1, kuyruk oranı, bakulum şekli vb. kök sayılarında görülen farklılıklar nedeniyle tüm yayılış alanlarını kapsayan detaylı bir çalışmada populasyonlar arası ve populasyon içi varyasyonlar göstermesi mümkündür. Bu kayıt türün Türkiyeden ikinci kaydıdır. Hatay kaydı Türkiyeden Kilis haricindeki tek kayıt bölgesi olduğu için türün yayılış alanının ortaya konulmasında önemli bir sonuçtur. Hataydaki yeni kayıt bölgelerinin korunması türün Türkiyede varlığını sürdürebilmesi bakımından da önemli olacaktır.
