The First Cytogenetic Characterization of Atemnids: Pseudoscorpions with the Highest Chromosome Numbers (Arachnida: Pseudoscorpiones)

Original language description

The karyotypes of pseudoscorpions of the family Atemnidae (Arachnida: Pseudoscorpiones) were studied for the first time. Karyotype data for 7 species have been obtained. The diploid chromosome numbers of most species considerably exceed the numbers reported in pseudoscorpions so far, with males ranging between 65 and 143. In spite of this, the sex chromosome system of atemnids is characterized by the same features that are found in the majority of other pseudoscorpions with an X0 system; the X chromosome is metacentric and is the largest chromosome or one of the largest chromosomes of the karyotype. Male meiotic cells of Atemnus politus contain 1 or 2 autosome multivalents; most specimens had 2 multivalents. The multivalents were composed of 4, 6, 8 or10 chromosomes. Multivalent number and structure was consistent within each of the studied individuals. The same number of chromosomes in all of the males examined suggests that multivalents are generated by reciprocal translocations. Th
