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, 36G); tubular ducts present or absent (Fig. 36F); 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, 36B). Stigmatic clefts shallow to deep, each containing 3–12 stigmatic spines (Fig. 36C). 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); antenna 7 to 9 segmented (Fig. 36M); legs each with tibio-tarsal articulatory scleroses (Fig. 36I) (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).
