Description.
Adult (
Figs 43–50
). Colour: Male: general colour pale cream to ochraceous with orange-brown to brown markings. Vertex pale with thin black transverse line on anterior margin and a pair of pale brown spots in vicinity of fovea; genal processes with pale grey infuscation towards apices; antennal segments 1–2 ochraceous to brown; segment 3 darker apically; segments 4–10 dark brown to black; pronotum pale with a pair of pale brown lateral spots; mesopraescutum with a pair of short broad triangular markings confluent with anterior margin; mesoscutum with two pairs of orange-brown to brown longitudinal submedial stripes; mesoscutellum ochraceous; wings clear with anterior half of vein Cu1a distinctly suffused dark brown to black; legs pale with dorsal brown infuscation; fore- and mid-tarsi dark brown to black; hind basitarsi with dorsal infuscation, distal segment of hind tarsi dark brown to black; abdominal tergites with a broad dark brown to black longitudinal medial stripe, and a pair of thin dark brown longitudinal lateral stripes; proctiger and subgenital plate ochraceous; parameres with brown to dark brown apices; proximal segment of aedeagus dark brown to black, distal segment pale. Female: as for male, except with slightly paler markings; proctiger with dark brown to black infuscation confluent with lateral margins of circum-anal pore ring; subgenital plate with pale brown infuscation towards apex.
Structure: measurements and ratios as in Tables 1–5. Antennae moderate in length, 1.60 times width of head; genal processes elongate, conical with rounded apices, anterior margin of vertex rounded from dorsal aspect, delineated from genal processes by prominent ridge; vertex with weak medial suture; pronotum with weak anterior, medial node; thorax weakly arched, head little wider than pronotum and mesoscutum, fore wings short with broadly rounded apex; Rs short, mostly straight except distally, terminating well short of wing apex; vein M1+2 terminating short of wing apex; cell m1 short, broadly triangular, m1 cell value 0.70–0.86; cell cu1 short triangular, cu1 cell value 1.03–1.18; vein Cu1a weakly arched; radular areas prominent, elongate triangular in cells m2 and cu1; male terminalia as in
Fig 60–61
; proctiger long, thin, without lateral expansions; parameres short, with basal expansion, strongly incurved towards apices. Female terminalia as in
Fig. 62
; proctiger short broad with angular dorso-posterior margin from lateral aspect; subgenital short, broadly rounded, triangular from lateral aspect.
Nymph. Unknown.
Etymology.
Named after the host plant,
Allocasuarina luehmannii
.
Distribution.
Recorded from two widely separated localities in inland south-eastern Queensland and inland south-eastern South
Australia
(
Fig. 137
).
Host plant.
Recorded from
Allocasuarina luehmannii
(R.
Baker
) L.A.S.Johnson
(bull oak).
Allocasuarina luehmannii
occurs as a
5–15 m
tree in woodland in non-calcareous soils from Mareeba, Queensland through central Queensland and New South
Wales
, to north-western Victoria and eastern South
Australia
to S of Bordertown (
Wilson & Johnson 1989
).
Comments
. This species has been collected rarely from only two, widely separated localities: three specimens from south-eastern Queensland, and one from south-eastern South
Australia
. Both series were collected from
A. luehmannii
.
Aacanthocnema luehmannii
is very close morphologically to
Aa. dobsoni
,
Aa. huegelianae
and
Aa. torulosae
(see Comments under
Aa. dobsoni
for diagnoses).
