Ceroplastes floridensis Comstock, 1881 

( Figs 10View FIGURE 10, 11View FIGURE 11)

Ceroplastes floridensis Comstock, 1881: 331  .

Diagnosis. Body covered with thick white wax without a distinct dorsal horn at maturity ( Fig. 10AView FIGURE 10). Dorsum with Ceroplastes  - type pores of 4 types present: mono-, bi-, tri- and quadrilocular pores ( Fig. 11AView FIGURE 11); bi- or trilocular pores frequent; anal plates each with 1 discal seta and 3 apical setae ( Fig. 11DView FIGURE 11); and dorsal setae blunt, sparsely present on dorsum except for clear areas ( Fig. 11BView FIGURE 11). Marginal setae numbering 8–12 in a row between anterior and posterior stigmatic clefts on each side ( Figs 10CView FIGURE 10, 11JView FIGURE 11). Stigmatic clefts shallow, each with conical or bullet-shaped stigmatic spines arranged in about 2–3 rows ( Figs 10DView FIGURE 10, 11KView FIGURE 11). Venter with multilocular disc-pores present on all abdominal segments, with a few pores present laterad of meta-, meso- and procoxa ( Fig. 11EView FIGURE 11); tubular ducts each with a swollen inner ductule, arranged in submarginal ring ( Figs 10GView FIGURE 10, 11GView FIGURE 11); antenna 6 segmented ( Figs 10EView FIGURE 10, 11LView FIGURE 11); and legs without tibio-tarsal articulatory scleroses ( Figs 10FView FIGURE 10, 11FView FIGURE 11) (partially adopted from Hodgson & Peronti 2012).

Material examined. 2 ♀♀, LAOS, Pakse Dist., Champasak Prov., 11.vii. 2015, coll. P.P. Soysouvanh, on Duranta erecta  L. ( Verbenaceae  ); 1 ♀, Pakngum Dist., Vientiane Capital, 13.i.2015, on Nephrolepis  sp. ( Nephrolepidaceae  ) (same collector); 1 ♀, on Chrysophyllum cainito  L. ( Sapotaceae  ) (same locality, date and collector); 1 ♀, 2.viii.2016 (same locality, host plant and collector).

Hosts. Polyphagous. According to García Morales et al. (2016), C. floridensis  has been recorded from plants belonging to 152 genera in 67 families.

Distribution. All zoogeographical regions; Oriental Region ( India, Indonesia, Malaysia and Vietnam) ( García Morales et al. 2016); Laos (new country record).

Economic importance. Hamon & Williams (1984) noted that C. floridensis  is an economic pest on diverse ornamental plants; it has also been recorded as an important pest of citrus in the Aegean islands ( Argyriou & Kourmadas 1980), Egypt ( Salem & Zaki 1984; Swailem et al. 1976), Florida ( Hamon & Williams 1984), Israel ( Podoler et al. 1981; Peleg & Bar-Zakay 1995), the Mediterranean basin ( Argov et al. 1987) and Turkey ( Elekçioğlu & Senal 2007).

Remarks. Ceroplastes floridensis  is rather closely related to C. japonicus Green  , but differs from it mainly in the arrangement of the stigmatic spines. Adult females of C. floridensis  have the groups of stigmatic spines distinctly separated by marginal setae between anterior and posterior stigmatic clefts; whereas C. japonicas  has an almost continuous row of stigmatic spines between the clefts, with only a few marginal setae scattered amongst them ( Hodgson & Peronti 2012).
