Ceroplastes floridensis Comstock, 1881: 331  .

Diagnosis. Body covered with thick white wax without a distinct dorsal horn at maturity ( Fig. 10A View Figure ). Dorsum with Ceroplastes  - type pores of 4 types present: mono-, bi-, tri- and quadrilocular pores ( Fig. 11A View Figure ); bi- or trilocular pores frequent; anal plates each with 1 discal seta and 3 apical setae ( Fig. 11D View Figure ); and dorsal setae blunt, sparsely present on dorsum except for clear areas ( Fig. 11B View Figure ). Marginal setae numbering 8–12 in a row between anterior and posterior stigmatic clefts on each side ( Figs 10C View Figure , 11J View Figure ). Stigmatic clefts shallow, each with conical or bullet-shaped stigmatic spines arranged in about 2–3 rows ( Figs 10D View Figure , 11K View Figure ). Venter with multilocular disc-pores present on all abdominal segments, with a few pores present laterad of meta-, meso- and procoxa ( Fig. 11E View Figure ); tubular ducts each with a swollen inner ductule, arranged in submarginal ring ( Figs 10G View Figure , 11G View Figure ); antenna 6 segmented ( Figs 10E View Figure , 11L View Figure ); and legs without tibio-tarsal articulatory scleroses ( Figs 10F View Figure , 11F View Figure ) (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).
