Saissetia miranda (Cockerell & Parrott in Cockerell, 1899)

( Figs 49 , 50 )

Lecanium oleae mirandum Cockerell & Parrott in Cockerell, 1899: 12 .

Diagnosis. Marginal setae mostly with bifid or fimbriate apices ( Fig. 50F ); with 17–23 setae present between anterior and posterior stigmatic clefts on each side ( Fig. 49E ). Venter with multilocular disc-pores abundant around vulvar area, plus a few pores present laterad of metacoxa ( Fig. 50I ); tubular ducts each with a narrow inner ductule, present in submarginal areas ( Figs 49C , 50L ) (partially adopted from Williams & Watson 1990; Choi & Lee 2017b).

Material examined. 5 ♀♀, LAOS, Wattay International Airport, Sikhottabong Dist., Vientiane Capital, 30.iv.2015, coll. J.Y. Choi, on Dieffenbachia seguine (Jacq.) Schott (Araceae) .

Hosts. Polyphagous. According to García Morales et al. (2016), S. miranda has been recorded from plants belonging to 58 genera in 26 families.

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia and Taiwan) ( García Morales et al. 2016); Laos (new country record).

Economic importance. Dean & Hart (1972) considered S. miranda to be a potential pest of citrus in Texas, and it was described as a common pest of ornamental plants in Florida ( Hamon & Williams 1984).

Remarks. Saissetia miranda was synonymized with S. oleae (Olivier) but was subsequently reinstated as a valid species based on the different numbers of marginal setae ( De Lotto 1969). It has 17–23 marginal setae between anterior and posterior stigmatic clefts on each side, whereas S. oleae has only 5–13 setae in this position.
