Cyriopagopus sp. sumatran tiger is a very beautiful bird spider due to its size, behavior and coloration from West-Sumatra. The “tiger” in her name refers to the remarkable and ongoing pattern on her abdomen, which is different than the far more famous Cyriopagopus Schioedtei. Males are brown with black legs and white bands around the joints, which is in contrast with the green and beige males of the other species from the Cyriopagopus-genus.

The legs are very robust and the carapace can grow up to 3cm. Until now the bird spider hasn’t been officially published yet. The subfamily of the Ornithoctoninae (known as “earth tigers”, due to the patterns on their abdomen) mostly consists burrowing bird spiders living deep underground, except for spiders of the Cyriopagopus– and Phormingochilus-genus.


The species formerly placed in Haplopelma are medium to large spiders; for example, Cyriopagopus schmidti females have a total body length, including chelicerae, up to 85 mm (3.3 in), with the longest leg, the first, being about 70 mm (2.8 in) long.

The carapace is generally dark brown. They have eight eyes grouped on a distinctly raised portion of the cephalothorax, forming a “tubercle”. The forward-facing (prolateral) sides of the maxillae have “thorns” which act as a stridulating organ. The first leg is usually the longest, followed by the fourth, second, and third. Mature females have an M-shaped spermatheca. Mature males have a spur on the forward-facing sides of the tibiae of the first pair of legs and a pear-shaped palpal bulb with a wide, curved embolus.


Because of the fact Cyriopagopus sp. sumatran tiger is a very timid bird spider, they might react very defensive towards every disturbance nearby. Adult version live high in the trees, while their younger brothers and sisters live closer to the surface between rocks, stones or even lower, adding terrestrial prey to their menu.


  • Only start breeding 4-6 weeks (or later) after the spider molted. If the female molts between pairing and cocoon, the eggs will remain unfertilized.
  • Make sure the female is well-fed (not obese) before you introduce the male.
  • Plan mating in autumn.
  • Provide an escaping route for the male.
  • Plan the pairing at the end of wet season and let the cage dry out for 2/3 months, while temperatures drop to 22/23°C. Systematically raise up temperature and humidity. This will trigger the female to start making the cocoon.
  • Arm yourself with long greased tweezers. Seperate male and female immediately after mating.
