DIAGNOSIS: Recognized by bold contrasting markings of dark mahogany and pale gray, and endosoma C-shaped, sturdy, expanded apically; dorsal and ventral straps separated by wide area of membrane; dorsal strap terminating in large, well-formed subapical secondary gonopore.

DESCRIPTION: MALE: Mean total length 2.96, mean pronotum width 0.94. COLORATION (pl. 1): Contrasting bold markings of dark mahogany on head, calli, mesoscutum, scutellum, wide distal margin of corium and cuneus, femora, and venter and with contrasting pale gray on posterior lobe of pronotum, clavus, corium anteriad of posterior angle of claval commissure, base of cuneus, and legs distad of femoral apices; hemelytral membrane darkly fuscous, small areole mahogany, large areole and region near cuneus translucent. SURFACE AND VESTITURE (figs. 2A, C, pl. 1): Dorsal vestiture mixed, with silvery shining, somewhat sericeous setae covering paler colored areas and golden sericeous setae or brown simple setae over darker colored areas of hemelytron; narrow row of black setae on distal edge of corium; dorsum covered with dense, curved microtrichia and minute bumps (fig. 2C). STRUCTURE: Head (figs. 2A, B, pl. 1): Closely conforming to anterior margin of pronotum, eyes moderately large, occupying three-quarters height of head in lateral view; antenna inserted level with ventral margin of eye, eyes weakly emarginate at fossa; antennal segment 2 moderately long (0.95), 1.25 times width of head; labium reaching to apex of metacoxa. Thorax (pl. 1): Pronotum subquadrate, posterior margin weakly excavated. Pretarsus: Pulvilli present (fig. 2E). Hemelytron: Not elongate. GENITALIA (fig. 2F, pl. 6A–H): Pygophore: Conical, posteroventral surface not prominent. Endosoma: C-shaped, sturdy, with two distinct strongly sclerotized straps, separated by wide area of membrane or nonsclerotized cuticle; dorsal strap thin proximally, expanded to 2× proximal diameter distally; ventral strap wide, gradually tapered distally, terminating in large, discrete apical sclerite, separated from body of ventral strap by thin membrane. Secondary gonopore: Wellformed and ringlike, subapical; aperture apparently open on caudal surface abutting large, smooth, distally blunt sclerite situated between apices of dorsal and ventral straps. Phallotheca: Truncate apically with short tapered apex, aperture narrow on anterodistal surface gradually expanded posteriorly; anterior margin long, practically reaching anterior margin of pygophore. Parameres: Left paramere: Diameter of posterior process evenly thick; anterior process subequal in length to posterior process, with rounded apex and single apical bristle. Right paramere: Relatively large, slightly longer than left paramere; gradually tapered distally with small apical spine.

FEMALE (pl. 1): Coloration as in male; differing from male as in generic description; mean total length 3.01, mean pronotum width 0.96. GENITALIA (pl. 6I, J): Posterior margin of sternite 7: With posteriorly directed medial subtriangular projection. Vestibular sclerites: Ventral labiate plate: With obvious sclerotized platelike anteroventral extension just right of midline. Dorsal labiate plate: Extending longitudinally subequal to width of ring. Posteromedial region: With pair of pocketlike depressions and faint concentric ribbing, with a few minute raised tubercles on midline. Anterolateral region: Projecting anteriad of sclerotized rings by length of ring. Posterior wall: Interramal sclerite: Thickened dorsoposteriad to posterior wall.

ETYMOLOGY: Named for its host, Eucalyptus macrocarpa .

HOSTS: Recorded from Eucalyptus macrocarpa and E. macrocarpa subsp. elachanta (pl. 38A, B) ( Myrtaceae : Eucalypteae ).

DISTRIBUTION (map 1): Known from two collecting events on the west coast of Western Australia: one north of Perth, and one on the grounds of the Western Australian Herbarium. Both sites are in the southwestern phytogeographic subregion.
