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
No tarantula is considered deadly, but Chilobrachys have maybe the most potent venom, aside from Poecilotheria. Some cases have been reported where bites by Chilobrachys hardwickei resulted in gangrene and unconfirmed death.[4]
