1. Courtship dance, sperm transfer, and spermatophore morphology of Mastigoproctus giganteus are described. 2. During spermatophore formation, the male stands in front of the female, both animals face the same direction and the female embraces the male's opisthosoma with her pedipalps. 3. After spermatophore formation, the female picks up two long sperm carriers which the male then pushes into her genopore, embracing her from above and using his palpal fingers. 4. The reproductive biology is compared to that of other arachnids, the similarities between Uropygi and Amblypygi are demonstrated and the phylogenctical implications are discussed.
