Wallabicoris schwartzi , new species Figure 38; map 3; plate 5

DIAGNOSIS: Recognized by the chalkwhite coloration of the body and appendages (pl. 5), the large size, with a mean total length of 5.97, and the structure of the male genitalia, the secondary strap of the endosoma complete and with a broad submedial undulation and the left paramere relatively short, without an elevated shoulder on the posterior process, closed over most of the dorsal surface, and only weakly exceeding the margin of the pygophore in repose; phallotheca heavily sclerotized, nearly black (fig. 38). Breeds on Ozothamnus spp. Somewhat larger than the similarly colored Asteraceae-feeding W. baldersoni , significantly larger than the Asteraceae-feeding W. helichrysi , W. olearii , and W. ozothamni , as well as the Lamiaceae-feeding W. dicrastyli ; significantly larger still than the Thymelaeaceaefeeding W. pinocchii and the Lamiaceaefeeding W. cassisi , W. lachnostachy os, W. newcastelii , W. paradicrastyli , and W. prostantheri . Potentially confused with W. rutidosi , but that species much smaller, mean total length 4.87, and with a broken secondary endosomal strap.

DESCRIPTION: Male: Body greatly elongate, parallel sided, total length 5.67–6.16, l/w 5 3.43. COLORATION (pl. 5): Pronotum

(AMNH_PBI 00193992).

unicolorous pale, nearly white; hemelytron unicolorous pale, nearly white; markings on cuneus absent; membrane partially fumose, extreme base unicolorous with remainder, veins white; venter unicolorous pale or mostly so; antennal segment 1 dirty yellow, with one or two black medial setae; antennal segment 2 dirty yellow; 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 colora- tion, and with some sericeous or woolly setae. STRUCTURE: Head: Somewhat projecting, ratio wh/lh 5 3.64; antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderately large, ratio iod/wh 5 0.42; eyes occupying entire height of head in lateral view (hg0–1/ he20); labium just reaching onto abdomen. GENITALIA (fig. 38): Endosoma: Base very long, with an open U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap elongate apically, ratio lae/lsg 2.17; 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: More or less right angulate, dorsal surface with a hump; dorsal surface with a conspicuous keel. Left Paramere: Body elongate, somewhat exceeding pygophore margin; in dorsal perspective closed over about threefourths length; body not distinctly tapering toward apex; 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 3.25; body rounded laterally; posterior margin with a distinct protuberance subapically; body elevated at juncture with base; apex with short fingerlike process.

ETYMOLOGY: Named for Michael D. Schwartz, collector of all known specimens.

HOSTS: Recorded from Ozothamnus spp. , including O. ferrugineus (Labill.) Sweet , Ozothamnus argophyllus (A. Cunn. ex DC.) Anderb. (pl. 6A, B) and O. rosmarinifolius (Labill.) DC ( Asteraceae : Gnaphalieae ).

DISTRIBUTION (map 3): Tasmania.

DISCUSSION: The three species of Ozothamnus recorded as hosts for W. schwartzi occur in the near-coastal areas of Victoria as well as in Tasmania. Additional collecting might therefore extend the range of W. schwartzi onto mainland Australia.
