It is widely accepted among biologists that the Termites are most closely related to Cockroaches. The wood roaches, Genus Cryptocercus, live in wood and have parental care of offspring. Cryptocercus and termites possibly diverged from a common ancestor. Cockroaches have a number of features such as laying eggs in egg cases that are not found in termites that lay eggs individually.

As noted in a previous post, cockroaches have specialized cells called mycetocytes, that contain bacterial symbionts. Most termite species have bacterial and other symbionts, but those symbionts are not contained in mycetocytes. An exception is a primitive Australian termite, Mastotermes darwiniensis. Mastotermes darwiniensis mycetocytes are found in the fat body and the ovarioles of the females. The bacteria are necessary for survival and are transferred from the termite mother to the termite egg. The bacterial symbionts in the mycetocytes provide cockroaches with essential vitamins. It is assumed that the mycetocyte bacteria in Mastotermes darwiniensis has a similar function.
