In Phymata, the scutellum is triangular and shorter than the pronotum. In Macrocephalus, the scutellum is narrow and rounded, extending to the tip of the abdomen. [2] Phymatinae normally have a large fore femur and clubbed antennae. The forewing membranes sometimes lack distinct cells. [3] The antennae have four segments. There are two ocelli.
These four subspecies belong to the species Phymata americana: Phymata americana americana Melin, 1930 i c g b; Phymata americana coloradensis Melin, 1930 i c g b; Phymata americana metcalfi Evans, 1931 i c g b; Phymata americana obscura Kormilev, 1957 i c g; Data sources: i = ITIS, [1] c = Catalogue of Life, [2] g = GBIF, [3] b = Bugguide.net [4]
The basic body color is dark reddish-brown in males, while females are lighter yellow-brown. Moreover, in the males the antennae terminate with a cylindrical joint, thicker and longer than all other segments, while the females antennae are terminated by a more clavate joint, not as long as the preceding ones.

Phymata is a genus of assassin bugs belonging to the family Reduviidae, subfamily Phymatinae, [1] commonly called jagged ambush bugs. They can be a variety of colors, with their coloring helping them camouflage with the plants they live on.
The antenna surface is covered with large numbers of olfactory scales, hairs, or pits; as many as 1,370,000 are found on the antennae of a monarch. Antennae are extremely sensitive; the feathered antennae of male moths from the Saturniidae, Lasiocampidae, and many other families are so sensitive that they can detect the pheromones of female ...
Insects can feel with their antennae because of the fine hairs that cover them. [17]: 8–11 However, touch is not the only thing that antennae can detect; numerous tiny sensory structures on the antennae allow insects to sense smells, temperature, humidity, pressure, and even potentially sense themselves in space.
Large antennae on a longhorn beetle. Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
Myxophaga have several diagnostic features: the antennae are more or less distinctly clubbed with usually fewer than nine segments, mesocoxal cavities are open laterally and bordered by a mesepimeron and metanepisternum, the hind wings are rolled apically in the resting positions.
