Abstract:
Haemaphysalis sulcata (Acarina, Ixodidae) is a common ectoparasite of wild artiodactyls (mouflon and wild goat) in Sierra Nevada (Granada, southern Spain). A study of the spermatogonial meiosis of 15 H. sulcata males was carried out. The diploid complement is 2n = 21 and its sex determination is XX:XO. The behavior of the chromosomes in the different stages of meiosis was also investigated, and the possible presence of a secondary nucleolar organizer region in H. sulcata is discussed.
