Ceroplastes rubens Maskell, 1893


Ceroplastes rubens Maskell, 1893 

( Figs 12View FIGURE 12, 13View FIGURE 13)

Ceroplastes rubens Maskell, 1893: 214  .

Diagnosis. Body covered with reddish brown wax without a distinct dorsal horn at maturity ( Fig. 12AView FIGURE 12). Dorsum with Ceroplastes  - type pores of 3 types present: mono-, bi- and trilocular pores ( Fig. 13CView FIGURE 13); monolocular pores frequent; anal plates each with 1 discal seta and 3 apical setae ( Fig. 13EView FIGURE 13); and dorsal setae blunt, sparsely present on dorsum except for clear areas ( Fig. 13BView FIGURE 13). Marginal setae numbering 2–4 between anterior and posterior stigmatic clefts on each side ( Fig. 13HView FIGURE 13). Stigmatic clefts deep, each with a very large and bluntly conical medial seta, and two round lateral setae, plus smaller round setae arranged in 1 or 2 rows ( Figs 12CView FIGURE 12, 13AView FIGURE 13). Venter with multilocular disc-pores present on all abdominal segments, with a few pores present laterad of meta- and mesocoxa ( Fig. 13FView FIGURE 13); tubular ducts absent; antenna 6 segmented ( Figs 12DView FIGURE 12, 13KView FIGURE 13); and legs very short and poorly developed, each with tibia and tarsus fused ( Figs 12EView FIGURE 12, 13GView FIGURE 13) (partially adopted from Hodgson & Peronti 2012).

Material examined. 1 ♀, LAOS, Hadsayfong Dist., Vientiane Capital, 18.i.2016, coll. P.P. Soysouvanh, on Mangifera  sp. ( Anacardiaceae  ); 5 ♀♀, Khong Dist., Champasak Prov., 30.vii.2016, on Ixora  sp. ( Rubiaceae  ) (same collector).

Hosts. Polyphagous. According to García Morales et al. (2016), C. rubens  has been recorded from plants belonging to 168 genera in 79 families. In Laos, it has been recorded on Dracaena  sp. ( Asparagaceae  ) ( Suh & Bombay 2015).

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia, Laos, Malaysia, Philippines, Taiwan, Thailand and Vietnam) ( Suh & Bombay 2015; García Morales et al. 2016).

Economic importance. Yasumatsu (1958) considered C. rubens  to be an economically important pest of various plants; in addition, it has been described as a major pest of citrus in Australia ( Loch 1997) and Japan ( Yasumatsu 1958; Itioka & Inoue 1996).

Remarks. Ceroplastes rubens  is most similar to C. reunionensis Ben-Dov & Matile-Ferrero  but Hodgson & Peronti (2012) provided diagnostic characters to distinguish these two species, based on the distributions of their stigmatic spines and on their distributional ranges. Ceroplastes rubens  has 4 rows of stigmatic setae and a worldwide distribution, whereas C. reunionensis  has 5 rows of stigmatic setae and is only known from the island of Réunion in the Indian Ocean.
