Brevipalpus obovatus Donnadieu is a thelytokous species having two chromosomes in soma and germ line. G-banding pattern and internal differences during anaphase indicate that the two chromosomes are nonhomologous and that females are haploid with n = 2. The same number applies for the males of the s
