The leaf-footed bugs and allies make up the superfamily

Taxonomic rank

In biological classification, rank is the level in a taxonomic hierarchy. Examples of taxonomic ranks are species, genus, family, and class. Each rank subsumes under it a number of less general categories...

 Coreoidea of the true bug infraorder Pentatomomorpha

Pentatomomorpha

Pentatomomorpha is an infraorder of insects in the true bug order . It unites such animals as the plant bugs , stink bugs , flat bugs , seed bugs , etc. They are closely related to the Cimicomorpha.-Systematics:5 superfamilies are usually placed in the Pentatomomorpha...

There are 5 families

Family (biology)

In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

 presently recognized, but the Coreoidea as a whole are part of a close-knit group with the Lygaeoidea

Lygaeoidea

The Lygaeoidea are a sizeable superfamily of true bugs, containing the seed bugs and allies. The ash-gray leaf bug family , usually placed herein, might be closer to the Aradoidea....

 and Pyrrhocoroidea

Pyrrhocoroidea

Pyrrhocoroidea is a superfamily of insects in the infraorder of Pentatomomorpha....

 and it is likely that these three superfamilies are paraphyletic to a significant extent; they are therefore in need of revision and redelimitation.

The families are:

• Alydidae
  Alydidae
  Alydidae, commonly known as broad-headed bugs, is a family of true bugs very similar to the closely related Coreidae . There are about 40 genera with 250 species altogether...

• Coreidae
  Coreidae
  Coreidae are a large family of predominantly herbivorous insects that belong in the hemipteran suborder Heteroptera. There are more than 1,800 species in over 250 genera. They vary in size from 7 to 45 mm, making the larger species some of the biggest heteropterans. The body shape of coreids...

  Rhopalidae
  Rhopalidae, or scentless plant bugs are a family of true bugs. In older literature, the family is sometimes called "Corizidae". They differ from the related coreids in lacking well-developed scent glands. They are usually light-colored and smaller than the coreids...
