Cave Beetle; Xuedytes bellus
Xuedytes bellus, a cave dwelling beetle was discovered in a cave in Guangxi Province, China. Like much of southern China, this is in a vast landscape riddled with caves. This new species of beetle is about 9 mm in length, with elongated head and prothorax. First pair of legs are attached to the body segment immediately behind the head.
Beetles that evolve in the darkness of caves often take on a similar set of characteristics, including narrow bodies, spider-like appendages and loss of wings, eyes and pigmentation. Such beetles are an example of convergent evolution.
