Wallabicoris chrysocephali , new species Figure 3; map 3; plate 1

DIAGNOSIS: Recognized among those species with heavily yellow coloration by the nearly uniform but not intensely yellow dorsum (pl. 1), by the moderately large size, mean total length 5.40; the relatively short rather strongly declivent head, ratio head length/head width 3.51; the left paramere relatively short and deep bodied and only moderately projecting beyond margin of pygophore (fig. 3); and the secondary endosomal strap with a short, kinklike, submedial undulation (fig. 3). Breeds on Chrysocephalum apiculatum (Asteraceae) . Similar to W. maralinga and W. rutidosi in the relatively short, deep-bodied left paramere only moderately projecting beyond the margin of the pygophore, but coloration of dorsum in W. rutidosi not so uniformly yellow in many specimens. Distinguished from W. sandstonensis and W. waitzii by the much more elongate left paramere in those species projecting well beyond the margin of the pygophore, and the longer, more slender body, and more intensely yellow coloration in W. waitzii . Potentially confused with W. commoni , a species of similar size, mean total length 5.60, and uniform yellowish coloration, but secondary endosomal strap with a very broad subbasal undulation rather than a short medial twist as in W. chrysocephali .

DESCRIPTION: Male: Body moderately elongate, parallel sided, total length 5.18– 5.67, ratio l/w 5 3.52. COLORATION (pl. 1): Pronotum unicolorous yellow with a pale medial longitudinal stripe; hemelytron unicolorous yellow; markings on cuneus absent; membrane with elongate, contrasting, fumose marking at extreme base, remainder partially fumose, veins white; venter unicolorous pale or mostly so; antennal segment 1 yellow to dirty yellow, with one or two black medial setae; antennal segment 2 yellow to 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 3.49; antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderate, ratio iod/wh 5 0.47; eyes leaving gena moderately exposed in lateral view (hg3/ he20); labium just reaching onto abdomen. GENITALIA (fig. 3): Endosoma: Base mod- erately long, with an open U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap weakly elongate apically, ratio lae/lsg 1.63; apex of primary endosomal strap nearly straight; secondary endosomal strap very slender, of uniform width from endosomal bend to gonopore, reaching to level of secondary gonopore, with a short submedial undulation; secondary gonopore seen frontally in lateral view of endosoma. Phallotheca: More or less right angulate, dorsal surface with a hump; dorsal surface without 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 flattened, broadest at angulate apex; 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 2.83; body tapered from base to apex; posterior margin without distinct protuberance subapically; body elevated at juncture with base; apex with weakly elongate fingerlike process.

ETYMOLOGY: Named for the host genus Chrysocephalum Walp. (Asteraceae) .

HOSTS: Recorded only from Chrysocephalum apiculatum (Labill.) Steetz ( Asteraceae : Gnaphalieae ) or close relatives.

DISTRIBUTION (map 3): Recorded primarily from the McDonnell Ranges of central Australia in the Alice Springs region. The specimens from the Australian Capital Territory and New South Wales lack host data, but are morphologically very similar to material from Central Australia, suggesting a broad— but incompletely known—distribution.

DISCUSSION: Chrysocephalum apiculatum is very widely distributed in Australia. The records from New South Wales and the ACT may well be an indication that W. chrysocephali will prove to be more widely distributed as well.
