Wallabicoris halganii , new species Figure 12; map 1; plate 2

DIAGNOSIS: Recognized by the presence of numerous small dark spots on the hemelytra and pronotum (pl. 2), as well as dark spots at the base of the tibial spines; apical half of endosoma nearly straight and erect, secondary endosomal strap with a short submedial twist; left paramere greatly elongate, closed over most of dorsal surface, greatly extending beyond margin of pygophore in repose (fig. 12). Most similar to W. pityrodiellus in the presence of spots on the hemelytra, but spots lacking on the pronotum in that species, and tibiae without distinct spots at the bases of spines.

DESCRIPTION: Male: Body moderately elongate, parallel sided, total length 4.42– 5.12, ratio l/w 5 3.12. COLORATION (pl. 2): Pronotum pale, yellowish, with brown spots; hemelytron unicolorous pale, yellowish, with many small brown spots, especially on posterior lobe; red fascia on corium/clavus absent; markings on cuneus present as brown spots; membrane with elongate, contrasting, fumose marking at extreme base, remainder partially fumose, veins yellow; venter light green; antennal segment 1 yellow to dirty yellow, with one or two black medial setae; antennal segment 2 dirty yellow proximally, weakly to heavily infuscate distally; labium pale with segment 4 heavily infuscate; hind femora with many brown or black spots; hind tibial spines dark with conspicuous dark spots at bases. SURFACE AND VESTI- TURE: Dorsum with suberect black setae, especially on pronotum, intermixed with pale setae on hemleytron, and with some sericeous or woolly setae. STRUCTURE: Head: Moderately projecting, ratio wh/lh 5 3.20; antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space relatively small, ratio iod/wh 5 0.51; eyes leaving gena moderately exposed in lateral view (hg3/he20); labium reaching to about midpoint of abdomen. GENITALIA (fig. 12): 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 1.88; apex of primary endosomal strap nearly straight; secondary endosomal

(AMNH_PBI 00136984).

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 without a hump; 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 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 3.82; body more or less parallel sided; posterior margin without distinct protuberance subapically; body elevated at juncture with base; apex with short fingerlike process.

ETYMOLOGY: Named for the host genus, Halgania Gaudich (Boraginaceae) .

HOSTS: Recorded only from Halgania viscosa S. Moore (Boraginaceae) .

DISTRIBUTION (map 1): Known from a single collecting event at the southeastern margin of the Goldfields region of Western Australia.

DISCUSSION: Halgania viscosa is known from a limited area of Western Australia that includes the type locality of W. halganii . This is in strong contrast to other species of Halgania , such as H. cyanea Lindl. , which are very widely distributed and known from a very large number of collections.
