Chilocorus Leach, 1815

Chilocorus Leach, 1815: 116. Type species: Coccinella cacti Linnaeus, 1767, by monotypy.

Diagnosis.

Body length 2.5-4.8 mm. Dorsal body glabrous; elytra black or brown with white or orange markings; eye clearly emarginate. Antennae short, composed of 8 antennomeres; with scape symmetrical; 8th antennomere either as long as or markedly longer than antennomere 7. Clypeus long; labrum partly exposed. Pronotal base unbordered; prosternal process narrow without carinae; hypomeral fovea absent. All tibiae flattened and angulate externally, without apical spurs; tarsal claws strongly appendiculate. Elytral margin not reflexed with indistinct bead; epipleural foveae weak. Abdominal ventrite 6 visible in males; abdominal postcoxal lines separated medially, each running parallel to hind margin of ventrite (after Ślipiński 2007).

Ecology.

Although various scale insects are primary hosts of Chilocorus ( Escalona et al. 2017), some species at least accept aphids as prey ( Gordon 1985, Drea and Gordon 1990, Ślipiński 2007, Hodek and Honěk 2009). Nonetheless, there are some reports about some species of this genus, such as Chilocorus stigma (Say) which feed on some whitefly species, such as Aleurocanthus woglumi Ashby ( Dowell and Cherry 1981, Hodek and Honěk 2009).
