Diagnosis.
Body covered with thick white wax forming a distinct dorsal horn at maturity (
Fig. 6A
). Dorsum with
Ceroplastes
-
type
pores of
4 types
present: mono-, bi-, tri- and quadrilocular pores (
Fig. 7B
); bi- or trilocular pores abundant; anal plates each with 4 apical setae; and dorsal setae variable, usually blunt, evenly distributed on dorsum except for clear areas (
Fig. 7A
). Marginal setae spinose, each with a pointed apex; with 2–4 setae present between anterior and posterior stigmatic clefts (
Fig. 7K
). Stigmatic clefts shallow, each with conical or bulletshaped stigmatic spines, arranged in a triangular area composed of about 6 setal rows (
Figs 6C
,
7C
). Venter with multilocular disc-pores present on all abdominal segments, with a few pores present laterad of meta-, meso- and procoxa (
Fig. 7F
); tubular ducts each with a very narrow inner ductule, present on submarginal area of posterior abdomen and head (
Fig. 7G
); antenna 6 segmented (
Figs 6D
,
7L
); and legs without tibio-tarsal articulatory scleroses (
Figs 6E
,
7H
) (partially adopted from
Hodgson & Peronti 2012
).
Material examined.
4 ♀♀, LAOS, Paksong Dist., Champasak Prov.,
30.vii.2016
, coll. P.P. Soysouvanh, on
Persea americana
Mill. (Lauraceae)
.
Hosts.
Polyphagous. According to ScaleNet (
García Morales
et al
. 2016
),
C. ceriferus
has been recorded from plants belonging to 80 genera in 52 families. In
Laos
, it has been recorded on
Dracaena
sp. (
Asparagaceae
) and
Ficus
sp. (
Moraceae
) (
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.
Although
C. ceriferus
may be not a serious pest, some authors note that it can cause damage to numerous ornamental plants by producing honeydew, which fosters the development of sooty mold (
Williams & Kosztarab 1972
;
Hamon & Williams 1984
;
Hodgson & Henderson 2000
). Sooty mold blocks light and air from the leaves, impairing photosynthesis.

Remarks.
Ceroplastes ceriferus
is closely related to C.
pseudoceriferus
Green
, as indicated by only a narrow genetic distance in the DNA barcode region of COI (
Deng
et al
. 2012
;
Lee
et al
. 2012
); but these species differ morphologically in the number of marginal setae.
Ceroplastes ceriferus
has fewer than 15 slender marginal setae between the anterior stigmatic clefts, and about 3 marginal setae between the anterior and posterior stigmatic clefts on each side; whereas
C. pseudoceriferus
has about 40 marginal setae between the anterior stigmatic clefts, and about 10 marginal setae between the anterior and posterior stigmatic clefts on each side (
Gimpel
et al
. 1974
;
Hodgson & Peronti 2012
).
