Pulvinaria polygonata Cockerell 1905: 131.
Diagnosis.Dorsal derm with polygonal reticulations; tubular ducts present, but small ( Fig. 42E); duct tubercles present ( Fig. 42D). Marginal setae bluntly spinose, mostly with fimbriate apices ( Fig. 42A). Stigmatic clefts distinct, each containing 4 or 5 stigmatic spines ( Figs 41C, 42C). Venter with multilocular disc-pores usually each with 8 loculi, abundant around vulvar area, a few pores also present laterad of meta- and mesocoxa ( Fig. 42I); tubular ducts of 3 types: type I each with a broad inner ductule, present on medial area of head, thorax and anterior abdomen; type II each with a narrow inner ductule, present on medial and inner submarginal area of head, thorax and abdomen; and type III each with a filamentous inner ductule, present in submarginal areas ( Figs 41D, 42J); antenna 8 segmented (partially adopted from Williams & Watson, 1990).
Material examined. 10 ♀♀, LAOS, Kham Dist., Xiangkhoang Prov., 2.v.2015, coll. J.Y. Choi, on Citrussp. ( Rutaceae).
Hosts.Polyphagous. According to García Morales et al. (2016), P. polygonatahas been recorded from plants belonging to 10 genera in 7 families. In Laos, it has been found on Ficussp. ( Moraceae) ( Suh & Bombay2015).
Distribution.Mainly known from Australian, Oriental( Bangladesh, India, Laos, Philippines, SriLanka, Taiwanand Vietnam) and Palearctic Regions ( Suh & Bombay2015; García Morales et al. 2016). Economic importance. Mani & Krishnamoorthy (1998)considered P. polygonatato be a serious pest of mango ( Mangifera indica) in India. In addition, Williams & Watson (1990)noted that P. polygonatacould be a potential pest of citrus because of its host preferences. The species is frequently intercepted at U.S. ports ( Miller & Miller 2003).
Remarks. Pulvinaria polygonataclosely resembles P. aurantiiCockerell, but is easily separated by the number of stigmatic spines in each spiracular cleft: P. polygonatahas 4–5, whereas P. aurantiihas only 3 ( Takahashi 1955b).
