The Cimicomorpha are an infraorder of insects in the order Hemiptera, the true bugs. The rostrum and other morphology of all members apparently is adapted to feeding on animals as their prey or hosts. Members include bed bugs, bat bugs, assassin bugs, and pirate bugs.

Bersta is an extinct genus of hemipteran in the monotypic family Berstidae. It is known from two species found in the Cenomanian aged Burmese amber of Myanmar. The external morpology suggests that the genus were beetle mimics.

Cimicoidea is the name of a superfamily of insects belonging to the infraorder Cimicomorpha, including bedbugs and related families.

Lyctocoridae is a family of bugs, formerly classified within the minute pirate bugs of the family Anthocoridae.

The Microphysidae are a very small family of bugs, comprising only 5 extant genera.

Miroidea is a superfamily of true bugs in the order Hemiptera. There are about 7 families and more than 15,000 described species in Miroidea.

The Polyctenidae are a rarely collected family of parasitic bugs of the superfamily Cimicoidea. Polyctenidae species or bat bugs are obligate, hematophagous ectoparasites of bats. These insects are not to be confused with cimicid bat bugs, which are members of the family Cimicidae. A significant relationship appears to occur between the family groups and the species of hosts that indicates co-evolution and specialization.

Thaumastocoridae is a family of true bugs in the order Hemiptera. There are about 9 genera and more than 20 described species in the family Thaumastocoridae.

Thaumastocoris peregrinus, the bronze bug, is a true bug first described from Argentina, but is probably native to Australia. The species has been recorded in Africa, Europe, Middle East (Israel), North America, South America, Caribbean, and New Zealand as a pest of eucalyptus.
