Chilobrachys dyscolus is a species of spider in the tarantula family (Theraphosidae) native to Vietnam.

[3] While the species is usually a chocolate brown, grayish spider, after the molt it has a blue-black coloration all throughout the body.

Under normal circumstances this tarantula is either a light brown or black all throughout the body.

Although sometimes the front facing areas of the pedipalps and legs bright metallic blue color persist.

As most of the Chilobrachys genus, it digs intricate and beautiful tunnel systems in the substrate.
