Insects in the subfamily Phymatidae are commonly called ambush bugs after their habit of lying in wait for prey relying on their superb camouflage. Armed with raptorial forelegs, ambush bugs routinely capture prey ten or more times their own size. They form a subgroup within the assassin bugs.

Phymatidae are 5–12 millimetres (0.20–0.47 in) long. In Phymata, the scutellum is triangular and shorter than the pronotum. In Macrocephalus the scutellum is narrow and rounded and extends to the tip of the abdomen.[1]
Phymatidae normally have a large fore femur and clubbed antennae. The forewing membranes sometime lack distinct cells.[2]
The antennae have four segments. There are two ocelli. The beak has three segments. The tarsi also have three segments. The rear half of the abdomen expands beyond the edges of the wings.[3]
Phymatidae was often given family-level status and this classification is still used in some textbooks. Based on cladistic analyses, however, ambush bugs (Phymatidae) are part of the family Reduviidae (assassin bugs).
Phymatinae is derived from the Greek phymata meaning swollen which presumably refers to the enlarged abdomen and femora.[4]
Phymatinae contains the following species:[5]
