- Haplopelma hainanum is a species of spider in the family Theraphosidae (tarantulas), found in China.
- Cyriopagopus hainanus resembles C. schmidti, but can be distinguished by its dark black-brown body and the longer “thorns” on the forward-facing (prolateral) side of the maxillae. The carapace (upper surface of the cephalothorax is black-brown, the sternum (under surface of the cephalothorax) is red-brown; and the abdomen is dark brown, with six black stripes running across it and a black stripe down the centre of the upper surface.
- C. hainanus makes underground burrows, lined with silk, and often with silk alarm lines radiating from the mouth. The spider remains in its burrow during the day, emerging only at night to catch prey, mainly large insects.
