Pulvinaria maxima Green, 1904a: 206 

Diagnosis. Dorsum with anal plates each with 1 cylindrical discal seta, and 3 spinose and/or truncate setae on inner margin and apex ( Figs 35DView FIGURE 35, 36GView FIGURE 36); dorsal setae conical ( Fig. 36AView FIGURE 36); tubular ducts sparsely scattered ( Fig. 36FView FIGURE 36). Marginal setae stout and truncate, of 2 types (one long and slender; the other much shorter and thicker) ( Figs 35CView FIGURE 35, 36BView FIGURE 36). Stigmatic clefts each containing 4–8 stigmatic spines ( Fig. 36CView FIGURE 36). Venter with multilocular disc-pores usually each with 10 loculi, mainly present on posterior area of abdomen ( Fig. 36HView FIGURE 36); antenna 8 segmented ( Fig. 36MView FIGURE 36) (partially adopted from Hodgson 1994; Wang & Feng 2012b).

Material examined. 8 ♀♀, LAOS, Nan Dist., Sayaboury Prov., 29.x.2014, coll. J.Y. Choi, on Dimocarpus longan Lour.  ( Sapindaceae  ); 1 ♀, Beng Dist., Oudomxay Prov., 25.viii.2016, coll. P.P. Soysouvanh, on Lagerstroemia macrocarpa Wall.  ( Lythraceae  ); 2 ♀♀, Xaythany Dist., Vientiane Capital, 16.i.2017, on Mangifera  sp. ( Anacardiaceae  ) (same collector); 2 ♀♀, on Excoecaria cochinchinensis Lour.  ( Euphorbiaceae  ) (same locality, date and collector).

Hosts. Polyphagous. According to García Morales et al. (2016), M. maxima  has been recorded from plants belonging to 24 genera in 15 families.

Distribution. Mainly known from the Oriental Region ( India, Indonesia, Philippines, Sri Lanka, Taiwan, Thailand and Vietnam ( García Morales et al. 2016); Laos (new country record).

Economic importance. Prabhakar et al. (2008) noted that M. maxima  is a pest of cotton ( Gossypium  spp.), mulberry ( Morus  spp.), neem ( Azadirachta indica  ) and physic nut ( Jatropha curcas  ).

Remarks. Megapulvinaria maxima  is similar to M. orientalis (Reyne)  but differs in having 4–10 setae present between antennae, whereas M. orientalis  has only 2 interantennal setae. For comparisons with other species of Megapulvinaria  , see Wang & Feng (2012b).
