Remarks

• Systematics: Pulvinaria pistaciaeshaares some characteristics with P. polygonata. such as having each stigmatic cleft containing more than 3 stigmatic spines (P. pistaciae usually has 4 or 6, whereas P. polygonata has 4‒6, usually 5); spiracles each with a sclerotic plate; pregenital disc-pores each with 7 loculi; and dorsal areolations well developed. (Cao & Feng, 2020)
• Structure: Adult female P. pistaciae possesses a combination of the following: (i) body subcircular to broadly oval; (ii) derm sclerotized with reticulations developed, crowded together medially and becoming sparse and small submarginally; (iii) dorsal sub-marginal tubercles absent; (iv) dorsal tubular ducts usually absent, occasionally present; (v) anal plates triangular, together quadrate, posterior margin almost same length as anterior margin; (vi) marginal setae slender, setose and pointed, only a few with bifid apices; (vii) stigmatic clefts containing 4 or 6 spinose stigmatic spines; (viii) antennae each with 8 segments; (ix) legs with tibio-tarsal articulation and articulatory sclerosis developed; (x) claw without a denticle; (xi) pregenital disc-pores each with 5, 6, 7 or 9 loculi, mostly 7, present laterad to metacoxa; (xii) ventral tubular ducts of 5 types present (as detailed below); (xiii) type І ducts present in median area of thorax, anterior abdominal segments, head, and on inner submarginal area, present anteriorly between antennae; (xiv) type II ducts present medially on posterior abdominal segments and submarginal area around body, sparsely present on inner submarginal area and mediolateral thorax and anterior abdominal segments, and anteriorly between antennal bases; (xv) type III ducts present on posterior abdominal segments around vulvar area and posterior abdominal submarginal area, sporadically on submarginal area as far forward as anterior stigmatic clefts; (xvi) type IV ducts present on head, absent from between antennae, sparsely present on anterior abdominal submarginal area; and (xvii) type V ducts sparsely and sporadically present in a narrow submarginal band, absent from between antennae. (Cao & Feng, 2020)
• Economic Importance: When present in concentrated populations, the insects can eventually cause the death of the host. Pistacia chinensis (Anacardiaceae) is of ornamental, environmental and medicinal value in China. (Cao & Feng, 2020)
