Genus Saissetia Déplanche, 1859

Type species: Lecanium coffeae Walker, 1852, proposed by Ben-Dov (1989) and ruled by Opinion 1627 (1991).

Diagnosis. In life, dorsum of young females with distinct H-shaped ridge (Figs 49A, 51A) but in mature, convex specimens this ridge is lost. On microscope slide, dorsum with anal plates each with a discal seta and 3 apical setae (Figs 47D, 48G, 49D, 50G, 51D, 52F); dorsal setae spinose (Figs 48D, 50D, 52A); and dorsal tubercles present (Figs 48B, 50B, 52B). Marginal setae mostly with bifid or fimbriate apices (Figs 48F, 50F). Venter with tubular ducts present in submarginal areas (Figs 47C, 48L, 49C, 50L, 51C, 52H); legs each with a tibio-tarsal articulatory sclerosis (Figs 48J, 50J, 52I) (except in S. neglecta) (Hodgson 1994; Choi & Lee 2017b).

Remarks. Saissetia consists of 44 described species which are known from all zoogeographical regions (García Morales et al. 2016). Adult females of the genus are easily recognized by each anal plate having a discal seta and ventral tubular ducts present in a submarginal band (Hodgson 1994).
