Acizzia Heslop-Harrison

(Figs 26, 54, 75, 76, 82)

Diagnosis: Genal processes shorter than vertex, rounded or conical (Fig. 26). Forewing oblong-oval; with or without pattern; costal break present; tapered pterostigma; cell cu1 high, leaning towards the base of wing (Fig. 54). Metabasitarsus with 1 or 2 apical spurs. Male proctiger with a conspicuous posterior lobe which may or may not bear a secondary finger-like appendage.

Biology and damage: Attacks are mainly on young parts, causing chlorosis and necrosis and promoting the development of sooty mould due to the secretion of honeydew (Burckhardt 1993). Immatures produce wax threads and tend to accumulate on axils of leaves, inflorescences and just below the flower buds (Fig. 75). When the population is high, they can also be found along the leaves (Fig. 76) (field observation).

Host-plants: Predominantly on Acacia and Albizzia (Fabaceae) but also on other plant families such as Capparidaceae, Loranthaceae, Proteaceae, Sapindaceae and Solanaceae (Taylor & Kent 2013) .

Distribution: Old World. Some Australian species such as Acizzia uncatoides were introduced into other continents (Ouvrard 2017).— Colombia: Acizzia uncatoides (Hodkinson 1988) .

Remarks: This is the first record of Acizzia acaciaebaileyanae in South America.
