What is "alydidae"

Alydidae, commonly known as broad-headed bugs, is a family of true bugs very similar to the closely related Coreidae (leaf-footed bugs and relatives). There are about 40 genera with 250 species altogether. Distributed in the temperate and warmer regions of the Earth, most are tropical and subtropical animals; for example Europe has a mere 10 species, and only 2 of these occur outside the Mediterranean region.
