Chilobrachys is a genus of Asian tarantulas that was first described by Ferdinand Anton Franz Karsch in 1892.[2] They are found in India, Myanmar, Malaysia, China, Vietnam, Thailand and Sri Lanka. They are usually medium or large-sized, and they can stridulate by using small spines present on the chelicerae.[3]

Identification features
They have special stridulating organs in their chelicerae, which are made of short spines. Males have a palpal bulb which ends in a long and slender blade like spine, females have one pair of spermatheca. The anterior eyes form almost a straight line. Their legs have a narrower scapulae at the tip of the metatarsus.[3]
Deaths
Chilobrachys bites may be fatal. some cases have been reported where bites by Chilobrachys hardwickei resulted in gangrene and deaths.[4]
