Cryptocercus is a genus of Dictyoptera (cockroaches and allies) and the sole member of its own family Cryptocercidae.[1] Species are known as wood roaches or brown-hooded cockroaches. These roaches are subsocial, their young requiring considerable parental interaction. They also share wood-digesting gut bacteria types with wood-eating termites, and are therefore seen as evidence of a close genetic relationship, that termites are essentially evolved from social cockroaches.[2]
Cryptocercus is especially notable for sharing numerous characteristics with termites, and phylogenetic studies have shown this genus is more closely related to termites than it is to other cockroaches.[3] These two lineages probably shared a common ancestor in the early Cretaceous.[4]
