Selenocosmiinae sp 'Sarawak'

Selenocosmiinae sp. 'Sarawak', commonly known as the Sarawak Banded Tarantula, is a rare and visually striking Old World tarantula originating from Sarawak's dense, humid rainforests, Malaysian Borneo. As an undescribed species within the Selenocosmiinae subfamily, it remains scientifically unclassified at the genus level. Still, it is strongly believed to be related to the Phormingochilus, Lampropelma, and Omothymus lineages—arboreal or semi-arboreal spiders known for their speed, defensive nature, and stunning coloration.

This species is named for its contrasting leg banding, which often appears in cream, yellow, or bronze against a dark brown or slate-black base. The banded pattern, which becomes more prominent as the spider matures, gives it a fierce, tiger-like aesthetic and makes it stand out among Southeast Asian arboreals. Its carapace may display a subtle metallic or golden sheen, especially after a fresh molt.

The Sarawak Banded Tarantula in captivity will readily take to vertical cork bark retreats and construct silk curtains or deep web tunnels, often sealing itself in for extended periods during pre-molt or when establishing territory. Like other Selenocosmiinae, this species is fast, highly defensive, and potent in venom, with no urticating hairs and a strong tendency to flee or posture when disturbed. Because of these traits, it is not suitable for handling and is best reserved for advanced keepers.
