Saissetia Déplanche, 1859


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 49AView FIGURE 49, 51AView FIGURE 51) 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 47DView FIGURE 47, 48GView FIGURE 48, 49DView FIGURE 49, 50GView FIGURE 50, 51DView FIGURE 51, 52FView FIGURE 52); dorsal setae spinose ( Figs 48DView FIGURE 48, 50DView FIGURE 50, 52AView FIGURE 52); and dorsal tubercles present ( Figs 48BView FIGURE 48, 50BView FIGURE 50, 52BView FIGURE 52). Marginal setae mostly with bifid or fimbriate apices ( Figs 48FView FIGURE 48, 50FView FIGURE 50). Venter with tubular ducts present in submarginal areas ( Figs 47CView FIGURE 47, 48LView FIGURE 48, 49CView FIGURE 49, 50LView FIGURE 50, 51CView FIGURE 51, 52HView FIGURE 52); legs each with a tibio-tarsal articulatory sclerosis ( Figs 48JView FIGURE 48, 50JView FIGURE 50, 52IView FIGURE 52) (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).
