(Figs 40, 78, 105)

Uracanthus cupressianus Rondunuwu and Austin, 1988: 110   .


Male. Body length, 12.76–18.06 mm; width, 2.11–3.20 mm.

Colour (Fig. 40). Body light reddish brown with head, thorax, antennae, scutellum, femora, and basal elytra often darker. Head with dense, long, golden pubescence. Pronotal disc with 2 broad longitudinal stripes of dense, long, golden pubescence, a narrow, longitudinal, glabrous median line between stripes, and 4 vague sparsely haired or glabrous spots near the median line; pronotum with a narrow longitudinal stripe of dense, long, golden pubescence on each side near sternum; ventral surface of prothorax with sparse golden pubescence. Elytra covered with dense, short, golden pubescence but pubescence near prothorax much longer. Body colour may vary from yellowish brown to reddish brown. The glabrous median longitudinal line on the pronotal disc may vary from narrow to wide.

Head. Postclypeus subtriangular and flattened, with sparse punctures; frontoclypeal suture deep and narrow in middle; distance between lower lobes of eyes 1.72–1.82 × as long as distance between upper lobes of eyes; distance between upper lobes of eyes 0.76–0.94 × as long as distance between eyes on ventral side; genal length 0.26–0.32 × as long as head width immediately below eyes. Antennae shorter than body; segments 5–10 subcylindrical.

Thorax and abdomen. Pronotum 1.26–1.54 × as long as width, rounded at side; posterior margin 1.14– 1.32 × as wide as anterior margin; pronotal disc finely punctate; disc and sides strongly rugose transversely. Scutellum semicircular, glabrous. Elytra 4.28–5.47 × as long as prothorax and 4.13–4.44 × as long as shoulder width; each elytron with 3 longitudinal carinae; elytra with coarse punctures on basal 1/3 and fine punctures on the rest 2/3; elytral apex rounded or slightly pointed. Apex of terminal sternite slightly emarginate.

Male terminalia. Apex of ventral median lobe pointed and apex of dorsal lobe shallowly emarginate; dorsal lobe slightly longer than ventral lobe; Spined region of internal sac divided into two sections; first section longer than basal unspined region, with sparse multi-branched spines at base and very dense long simple spines on the remaining part; second section about 3 × shorter than first section, with sparsely simple spines; a short unspined gap between sections ( Fig. 78a). Eighth sternite, rounded at sides, widely emarginate at apex, long and fairly long setae arising terminally; ventral surface with sparse cloud-like processes ( Fig. 78b). Eighth tergite long and narrow, emarginate at apex, with fairly dense simple spines in middle area ( Fig. 78c). Paramere 3.0–3.1 × as long as wide, cylindrical in shape, apex rounded with sparse long and short setae ( Fig. 78d).

Female. Body length, 15.29–19.67 mm; width, 2.68–3.87 mm.

Abdomen more robust, antennae and legs shorter; the median glabrous longitudinal line at pronotal disc broader; elytra 4.51–5.13 × as long as prothorax and 3.92–4.12 × as long as shoulder width.

Ovipositor and spermatheca. Ovipositor relatively long in the genus; styli arising terminally with short hairs ( Fig. 78e). Spermatheca heavily curved; spermathecal gland arising near base ( Fig. 78f).

Distribution Southeastern South Australia ( Fig. 105).


Known hosts are Cupressus sempervirens   , C. macrocarpa   , and C. arizonica   . Adults were collected from December to February.


This species resembles U. acutus   but differs in having the pronotal disc with denser pubescence and more transverse rugae on disc, and the apex of the elytra not strongly pointed.
