Identification: This suborder may be most easily recognized
by the development of the hind coxae which separate the first visible
abdominal sternum. In the other suborder (Polyphaga), the hind coxae
do not completely separate the first visible abdominal sternum. In
addition to this feature, Adephaga usually have the hind trochanters
particularly well developed and projecting free from the femur.
In Polyphaga the hind trochanters are usually less conspicuous. The
presence of a well developed notopleural suture, while more difficult
to appreciate, will identify this suborder. This suture is absent in
Polyphaga.
