Morphology

Adult Coccinelloidea have a reduced tarsal formula (each tarsus with 4 or 3 segments), hind coxae separated by more than 1/3 their width, the intercoxal process of abdominal ventrite 1 usually broadly rounded or truncate, hindwings with reduced anal veins and lacking a closed radial cell, the adeagus resting on its side when retracted and the phallobase usually reduced.⁴

Larval Coccinelloidea have a unisetose pretarsal claw, spiracles that are usually annular, and the sensory appendage of the second antennal segment usually as long as the third segment.⁵

Families

The family constituency of this lineage has changed considerably over time, from as few as four or five recognized families in 1970⁶ to 15 in 2015.⁷
