This species was described from Hawaii,
Jamaica
and Florida, but subsequently has been recorded from various Pacific islands:
Kiribati
(
Mound & Walker, 1987
);
New Caledonia
(
Bournier & Mound, 2000
);
French Polynesia
(
Hoddle et al., 2008
). Reference material used for the present study included specimens from
Kiribati
that previously had been compared to
type
specimens (
Mound & Walker, 1987
). Females apparently identical to these reference specimens are listed below from several localities in northern
Australia
. One female (in ANIC) collected in
Thailand
in 2003 has also studied. In contrast, females listed below from near Broome, Western
Australia
, have the pronotal discal setae slightly weaker, but with no further apparent differences. Males of this species have not previously been known, and have been found only amongst these Western Australian series. From this occurrence of males it is concluded that
pandens
probably originated in
Australia
, and that a female-only strain with limited variation has been distributed across the Pacific to the Caribbean. The species appears to be polyphagous, although the only plant from which larvae have been taken together with adults was a species of
Cassytha
(Lauraceae)
, a genus of parasitic scrambling vines that is widespread across
Australia
.
Female macroptera.
Very similar in colour and structure to
cissus
and
amyae
described above; antennal segments IV–V largely pale with apex shaded, VI brown with variable pale area basally. Ovipositor length scarcely more than 200 microns.
Male macroptera.
Similar to female, but antennae paler, segment VI largely yellow. Fore tibial armature similar to large and small males of
cissus
; terga laterally without prominent teeth, VII with a few small tooth-like lobes (
Fig. 22
); tergum IX with median pair of setae arising separately, further apart in large male than in small male, with no microtrichia laterally; sterna VIII and IX with transverse band of microtrichia.
Larvae II.
Yellow, tergum X dark on posterior half, antennal segments lightly shaded; abdominal terga each with three pairs of setae with broadly capitate and fimbriate apices, similar setae on head and thorax. Pupae with setae finely acute.
