Abstract
Currently,
about 11,000 oribatid mites have been described, but chromosome numbers have
been reported for only a few species. Furthermore, the oribatid mites are a
valuable model for holocentric chromosomes in cytogenetic studies. The diploid
chromosome number is generally 2n = 18 in oribatid mites, though some
have 2n = 16 or 30. Although there are many studies on the morphology
and systematics of Phauloppia lucorum (Koch, 1841) (Oribatida:
Oribatulidae), there is no information about its karyotype or chromosome
numbers. The aim of this study is to investigate the chromosome number,
monoploid ideogram and detailed chromosomal measurements of P. lucorum.
The diploid chromosome number of P. lucorum was found to be 2n =
12. The total haploid chromosome length and the average chromosome length were
7.39 µm and 1.23 µm respectively. The chromosome lengths varied from 0.91 to
1.67 µm. In conclusion, these results are the first for the chromosome numbers
and karyotype analysis for P. lucorum.

Abstract
Günümüzde, 11,000
oribatid akar türü tanımlanmıştır fakat çok az sayıda türün kromozom sayısı
bildirilmiştir. Ayrıca oribatid akarlar sitogenetik çalışmalarda holosentrik
kromozomlar için değerli bir modeldir. Genellikle oribatid akarlarda diploid
kromozom sayısı 2n = 16, 30 gibi bazı istisnalar dışında 2n = 18
şeklindedir. Phauloppia lucorum (Koch, 1841) (Oribatida: Oribatulidae)
üzerine çok sayıda morfolojik ve sistematik çalışmalar bulunmasına rağmen karyotip
ve kromozom sayısı hakkında bilgi yoktur. Bu çalışmanın amacı P. lucorum’un
kromozom sayısı, monoploid ideogram ve detaylı kromozom ölçümlerini
araştırmaktır. P. lucorum’un diploid kromozom sayısı 2n = 12
olarak bulundu. Toplam haploid kromozom uzunluğu ve ortalama kromozom uzunluğu
sırasıyla 7.39 µm, 1.23 µm’dir. Kromozom uzunluğu 0.91-1.67 µm aralığında değişmektedir.
Sonuç olarak, P. lucorum’un kromozom sayısı ve karyotip analizi ilk kez
bildirilmiştir.
