Agyrtidae, or primitive carrion beetles, are a small family of polyphagan beetles They are found in mostly temperate areas of the northern hemisphere and in New Zealand. They feed on decaying organic material.

Characteristics

Agyrtidae are small or middle-sized beetles (length 4–14 mm). They have usually oval body, but the Pterolomatinae are superficially similar to ground beetles. Abdomen is with five visible ventral sclerites, procoxal cavities internally open. Hindwings have anal lobe but no radial hinge.[1]
Systematics

Currently, about 60 species are known. The family is divided into three subfamilies:

Necrophilinae
Zeanecrophilus
Necrophilus
Agyrtinae
Agyrtes
Ecanus
Ipelates
Lyrosoma
Pterolomatinae
Apteroloma
Pteroloma

Until recently, species of this family had been included in the family Silphidae (as tribes Lyrosomatini and Agyrtini), but are now considered more closely related to the family Leiodidae.[2]
