DIAGNOSIS: The only Wallabicorissp.with a medial break in the secondary endosomal strap (fig. 35); some Rhamnaceae/ Sterculiaceaefeeders have a discontinuous secondary strap, but in those species the strap is absent from the proximal end of the secondary gonopore. Recognized among those species with heavily yellow coloration by the nonuniform yellow dorsum having a checkerboard pattern (pl. 4), by the moderate size, mean total length 4.87, the head weakly projecting beyond the anterior margin of the eyes, ratio head length/head width 3.19, the left paramere relatively short and deep bodied and only moderately projecting beyond margin of pygophore (fig. 36), and the secondary endosomal strap discontinuous, with a short medial break (fig. 36). Breeds on Rutidosis helichrysoides(Asteraceae). Similar to W. chrysocephaliand W. maralingain the relatively short, deep-bodied left paramere only moderately projecting beyond the margin of the pygophore, but coloration of dorsum in W. rutidosinot so uniformly yellow in many specimens. Distinguished from W. sandstonensisand W. waitziiby the much more elongate left paramere in those species projecting well beyond the margin of the pygophore, and the longer, more slender body, and uniform, more intensely yellow coloration in W. waitzii. Potentially confused with W. commoni, but that species substantially larger, mean total length 5.60, and with an unbroken secondary endosomal strap with a very broad subbasal undulation. Fig. 35.

DESCRIPTION: Male: Body moderately elongate, parallel sided, total length 4.67– 5.11, l/w 5 3.36. COLORATION (pl. 4): Pronotum unicolorous faded yellow; hemelytron mostly pale or faded yellow with some dirty areas; markings on cuneus present as partial infuscation; membrane with extreme base with an elongate fumose marking, remainder partially fumose, especially within cells, veins white; venter unicolorous pale or mostly so; antennal segment 1 unicolorous pale, dirty yellow with pale medial seta; antennal segment 2 dirty yellow; labium pale with segment 4 heavily infuscate; hind femora unicolorous pale, without 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:Moderately projecting, ratio wh/lh 5 3.18 (fig. 35A); antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderately large, ratio iod/ wh 5 0.39; eyes occupying entire height of head in lateral view (hg0–1/he20); labium reaching to midpoint of abdomen. GENI- TALIA (fig. 35E, F, 36): Endosoma:Base moderately long with an open U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap weakly elongate apically, ratio lae/lsg 1.95; 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, broken at about midpoint; secondary gonopore seen laterally in lateral view of endosoma. Phallotheca:Smoothly curving on dorsal margin; dorsal surface with a conspicuous keel. Left Paramere:Body elongate, somewhat exceeding pygophore margin; in dorsal perspective open over nearly entire length; body not distinctly tapering toward apex; anterior process arising at 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 2.65; body tapered from base to apex; posterior margin without distinct protuberance subapically; body elevated at juncture with base; apex with short fingerlike process.
ETYMOLOGY: Named for the host genus, RutidosisDC( Asteraceae: Gnaphalieae).
HOSTS: Recorded on multiple collecting events from Rutidosis helichrysoidesDC. (Asteraceae)(pl. 7B, C). The records from Amyemaand Eremophilaare either sitting records or the result of commingling specimens in the field.
DISTRIBUTION (map 3): Widely distribut- ed from central Australia( Northern Territory, South Australia) west into Queenslandand New South Wales.
DISCUSSION: Rutidosis helichrysoidesis very broadly distributed across the arid interior of Australia. Known records for W. rutidosiare from the Eyre Basin, although the actual distribution will require further sampling, to determine whether it is host specific and whether its distribution is coterminous with that of its host.
