DIAGNOSIS: Recognized by the pale coloration of the body and appendages (pl. 3), the

(AMNH_PBI 00173972).

moderately large size, mean total length 5.31, and the structure of the male genitalia, the secondary strap of the endosoma complete and with a broad submedial undulation and the left paramere elongate, deep bodied, and substantially exceeding the margin of the pygophore in repose, and without an elevated shoulder on the posterior process; right paramere relatively short and broad, with a distinct protuberance subapically on the posterior margin (fig. 19). Breeds on Olearia axillaris (Asteraceae) . Similar in size and coloration to W. baldersoni , W. ozothamni , and W. schwartzi ; distinguished from W. ozothamni by the shorter left paramere with an elevated shoulder on the posterior process in that species. Significantly larger than the pale Lamiaceae feeders such as W. cassisi , W. lachnostachy os, W. newcastelii , and W. paradicrastyli , but mean total length somewhat greater than in the pale Thymelaeaceaefeeder W. pinocchii .

DESCRIPTION: Body moderately elongate, parallel sided (l/w 5 3.11). COLORATION: Pronotum unicolorous pale; scutellum unicolorous with remainder of dorsum; hemelytron unicolorous white; markings on cuneus absent; membrane unicolorous pale, extreme base unicolorous with remainder, veins white; venter unicolorous pale or mostly so; antennal segment 1 unicolorous pale, with pale medial seta; antennal segment 2 unicolorous pale; labium pale with segment 4 heavily infuscate; hind femora with a few brown or black spots; hind tibial spines dark without dark spots at bases; SURFACE AND VESTITURE: Dorsum with reclining simple setae matching background coloration, and with some sericeous or woolly setae; STRUCTURE: Head: Weakly projecting, ratio wh/lh 5 4.21; antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderate, ratio iod/wh 5 0.45; eyes occupying entire height of head in lateral view (hg0–1/he20); labium just reaching onto abdomen up to midpoint; GENITA- LIA: Endosoma: Base very long, with a tight U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap elongate apically, ratio lae/lsg 2.50; apex of primary endosomal strap nearly straight; secondary endosomal strap very slender, of uniform width from endosomal bend to gonopore; secondary endosomal strap extent reaching to level of secondary gonopore; secondary endosomal strap curvature with a broad submedial undulation; secondary gonopore seen laterally in lateral view of endosoma; fingerlike protuberance at distal margin of secondary gonopore absent. Phallotheca: More or less right angulate; dorsal surface without a conspicuous keel. Left Paramere: Body very elongate, greatly exceeding margin of pygophore; in dorsal perspective closed over about three-fourths length; body not distinctly tapering toward apex; anterior process arising slightly forward of posterior margin of shaft; anterior process direction directed vertically; posteri- or process appearing tubular, fingerlike; posterior process shoulder without strong shoulder at base; base of posterior process at about level of paramere body or very weakly elevated. Right Paramere: Body short, broad, ratio lrp/wrp 2.54; body shape rounded laterally; posterior margin with a distinct protuberance subapically; body elevation elevated at juncture with base; apex tapered.

ETYMOLOGY: Named for the host genus Olearia Moench. ( Asteraceae : Astereae ).

HOSTS: Recorded from Olearia axillaris (DC.) Benth. (Asteraceae) .

DISTRIBUTION (map 3): Known from a single locality on the west coast of Western Australia.

DISCUSSION: The distribution of Olearia axillaris is almost exclusively costal, ranging from Port Hedland south and east to Sydney. Although we would not predict such a broad distribution for W. olearii , further collecting on Olearia axillaris will undoubtedly increase the known range of the species.
