Diagnosis.
Marginal setae variable in size, mostly with fimbriate apices (
Fig. 48F
); 11–18 setae present between anterior and posterior stigmatic clefts on each side. Venter with multilocular disc-pores mainly present around vulvar area, plus a few pores present laterad of meta- and mesocoxa (
Fig.
48I
); tubular ducts of 3 types: type I each with a broad inner ductule, present on medial submarginal area, and few ducts present around meso- and procoxa; type II each with a narrow inner ductule, present on inner submarginal area and medial area of thorax and abdomen; and type III each with a filamentous inner ductule, present on outer submarginal area (

Citrus
sp. (
Rutaceae
).
Hosts.
Polyphagous. According to
García Morales
et al
. (2016)
,
S. coffeae
has been recorded from plants belonging to 290 genera in 106 families.
Distribution.
All zoogeographical regions;
Oriental
Region
(
India
,
Indonesia
,
Laos
,
Malaysia
,
Philippines
,
Sri
Lanka
,
Taiwan
,
Thailand
, and
Vietnam
) (
Waterhouse 1993
;
García Morales
et al
. 2016
).
Economic importance.
Hamon & Williams (1984)
and
Alford (2012)
considered
S. coffeae
to be a pest on a variety of ornamental plants; it was also listed as a pest of coffee in
Ethiopia
(
Abebe 1987
) and of citrus in Mediterranean countries (
Franco
et al
. 2006
). In addition,
Rosen
et al
. (1971)
and
Ricalde
et al
. (2015)
noted that
S. coffeae
is one of the main pests on olives (
Olea europaea
) in
Israel
and
Brazil
.

coffeae
(Walker, 1852)
, adult female, from Choi & Lee (2017b). A, dorsal microduct; B, dorsal tubercle; C, dermal areolations; D, dorsal seta; E, stigmatic spines; F1-4, marginal setae; G, anal plates; H, preopercular pore; I, multilocular disc-pores; J, leg; K, ventral seta; L1-3, ventral tubular ducts; M, spiracular disc-pores; N, ventral microduct; O, antenna.
Remarks.
Saissetia coffeae
differs from other
Saissetia
species in having
3 types
of ventral tubular ducts in the submarginal areas. It is similar to
S. bobuae
Takahashi
in having ventral tubular ducts with broad inner ductules, but differs in having the following combination of character states (character states of
S. bobuae
in parenthesis): (i) dorsal tubercles present (absent), (ii) marginal setae mostly with fimbriate apices (with pointed apices), and (iii) antenna 8 segmented (7 segmented) (
Tao
et al
. 1983
;
Williams & Watson 1990
).
