Ceroplastes rubens Maskell, 1893


Ceroplastes rubens Maskell, 1893 

( Figs 12 View Figure , 13 View Figure )

Ceroplastes rubens Maskell, 1893: 214  .

Diagnosis. Body covered with reddish brown wax without a distinct dorsal horn at maturity ( Fig. 12A View Figure ). Dorsum with Ceroplastes  - type pores of 3 types present: mono-, bi- and trilocular pores ( Fig. 13C View Figure ); monolocular pores frequent; anal plates each with 1 discal seta and 3 apical setae ( Fig. 13E View Figure ); and dorsal setae blunt, sparsely present on dorsum except for clear areas ( Fig. 13B View Figure ). Marginal setae numbering 2–4 between anterior and posterior stigmatic clefts on each side ( Fig. 13H View Figure ). 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 12C View Figure , 13A View Figure ). Venter with multilocular disc-pores present on all abdominal segments, with a few pores present laterad of meta- and mesocoxa ( Fig. 13F View Figure ); tubular ducts absent; antenna 6 segmented ( Figs 12D View Figure , 13K View Figure ); and legs very short and poorly developed, each with tibia and tarsus fused ( Figs 12E View Figure , 13G View Figure ) (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.
