Tocama tonkinensis is a species of beetle of the family Scarabaeidae.[1] It is found in China (Guangxi, Guizhou, Hunan, Shandong, Yunnan), Cambodia, Laos, Myanmar and Vietnam.[2][3]

Description

Adults reach a length of about 24 mm (0.94 in).[4] They are sexually dimorphic, particularly with regard to the shape of the pygidium. Additionally, the intraspecific variation is significant in body colour. There are two main forms of body colour, black and castaneous.[3]
