Genus Megapulvinaria Yang, 1982 

Type species: Pulvinaria maxima Green, 1904a  , by original designation.

Diagnosis. Dorsum with anal plates each with 1 spinose discal seta, and 2 spinose and/or truncate setae on inner margin and apex ( Figs 35D View Figure , 36G View Figure ); tubular ducts present or absent ( Fig. 36F View Figure ); duct tubercles absent. Marginal setae stout and truncate, with 2 types (one long and slender; the other shorter or same length and thicker) ( Figs 35C View Figure , 36B View Figure ). Stigmatic clefts shallow to deep, each containing 3–12 stigmatic spines ( Fig. 36C View Figure ). Venter with 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 abdomen; type III: each with a filamentous inner ductule, present in submarginal areas) ( Fig. 36J View Figure ); antenna 7 to 9 segmented ( Fig. 36M View Figure ); legs each with tibio-tarsal articulatory scleroses ( Fig. 36I View Figure ) ( Hodgson 1994; Wang & Feng 2012b).

Remarks. Megapulvinaria  contains 5 described species that are mainly distributed in the Oriental and Australian regions ( García Morales et al. 2016). The genus is related to Pulvinarisca  , but is easily differentiated from the latter by possessing 2 types of marginal setae, and each anal plate having 1 discal seta and 2 spinose and/ or truncate setae ( Hodgson 1994); in contrast, Pulvinarisca  has only 1 type of marginal seta and each anal plate has 3 spinose setae only ( Hodgson 1994; Wang & Feng 2012b).
