Platycypha fitzsimonsi, the boulder jewel or Fitzsimon's jewel is a species of damselfly in the family Chlorocyphidae.

It is endemic to South Africa where its natural habitats include wooded and forested streams and rivers.

The mature male has an orange-red and black striped thorax and a distinctive red, black and blue abdomen.

Females and immature males are dark brown and khaki.

[2] Like several other Chlocyphidae, males extend and vibrate their tibia displaying the white colouration (foot waggling) towards ovipositing females as a courtship display.
