Cryptocercus

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]

Species

Found in North America and (especially temperate) Asia, there are 12 known species:
