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 49A View Figure , 51A View Figure ) 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 View Figure , 48G View Figure , 49D View Figure , 50G View Figure , 51D View Figure , 52F View Figure ); dorsal setae spinose ( Figs 48D View Figure , 50D View Figure , 52A View Figure ); and dorsal tubercles present ( Figs 48B View Figure , 50B View Figure , 52B View Figure ). Marginal setae mostly with bifid or fimbriate apices ( Figs 48F View Figure , 50F View Figure ). Venter with tubular ducts present in submarginal areas ( Figs 47C View Figure , 48L View Figure , 49C View Figure , 50L View Figure , 51C View Figure , 52H View Figure ); legs each with a tibio-tarsal articulatory sclerosis ( Figs 48J View Figure , 50J View Figure , 52I View Figure ) (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).
