DIAGNOSIS: Recognized by the presence of numerous small dark spots on the hemelytra but not on the pronotum (pl. 3); tibial spines without dark spots at bases; apical half of endosoma straight, erect, and elongate, secondary endosomal strap with a broad undulation proximally; left paramere greatly elongate, open over most of dorsal surface (fig. 26), greatly extending beyond margin of pygophore in repose. Most similar to W. halganiiin the presence of spots on the hemelytra, but spots present on the pronotum in that species, and tibiae with distinct spots at the bases of spines.
DESCRIPTION: Male: Body moderately elongate, ovoid, total length 5.17–6.02, ratio l/w 5 3.14. COLORATION (pl. 3): Pronotum unicolorous pale; hemelytron unicolorous pale with small brown spots; markings on cuneus present as individual small brown spots; membrane weakly fumose over entire areas, extreme base unicolorous with remain- der, veins white; venter light green; antennal segment 1 unicolorous pale, with one or two black medial setae; antennal segment 2 unicolorous pale; labium pale with segment 4 heavily infuscate; hind femora with many brown or black spots; hind tibial spines dark with very small dark bases. SURFACE AND VESTITURE: Dorsum with reclining simple setae matching background coloration, and with some sericeous or woolly setae. STRUCTURE: Head:Moderately projecting, ratio wh/lh 5 3.21 antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderate, ratio iod/wh 5 0.47; eyes occupying entire height of head in lateral view (hg0–1/he20); labium just reaching onto abdomen. GENI- TALIA (fig. 26): Endosoma:Base moderately long, with a tight U-shaped bend; distal half of shaft more or less straight and erect; primary endosomal strap weakly elongate apically, ratio lae/lsg 1.75; apex of primary endosomal strap weakly arcuate; secondary endosomal strap very slender, of uniform width from endosomal bend to gonopore, reaching to level of secondary gonopore, with a broad submedial undulation; secondary gonopore seen laterally in lateral view of endosoma. Phallotheca:Smoothly curving on dorsal margin; dorsal surface without a conspicuous keel. Left Paramere:Body very elongate, greatly exceeding margin of pygophore; in dorsal perspective open over nearly entire length; body tapered toward apex, apex elongate nipplelike; anterior process arising slightly forward of posterior margin of shaft; anterior process angled posterodorsally; posterior process appearing tubular, fingerlike; posterior process with strongly projecting shoulder at base; base of posterior process at about level of paramere body or very weakly elevated. Right Paramere:Body moderately elongate, ratio lrp/wrp 3.33; body tapered from base to apex; posterior margin with a distinct protuberance subapically; body elevated at juncture with base; apex with short fingerlike process.
ETYMOLOGY: Named for the host genus PityrodiaR. Br. (Lamiaceae).
HOSTS: Recorded only from Pityrodia cuneata(Gaudich.) Benth. (Lamiaceae).
DISTRIBUTION (map 1): Known only from the Shark Bay region of Western Australia.
DISCUSSION: Pityrodia cuneatais restricted to the Shark Bay region of Western Australiaand, on the basis of present knowledge, so is W. pityrodiellus.
