Wallabicoris pityrodii , new species Figures 27, 28; map 1; plate 4

DIAGNOSIS: Structure of left paramere unique among Wallabicoris spp. , the body of paramere greatly elongate, flattened, tonguelike, and with the anterior process placed about midway along the margin of the paramere (fig. 28); paramere projecting well beyond margin of pygophore; secondary endosomal strap without undulation or twisting; phallotheca with a dorsal crest. Body moderately large and broad, mean total length 5.28, mean ratio total length/ pronotal width 3.17. Head distinctly projecting beyond anterior margin of eyes, mean ratio head length/head width 2.52. General coloration pale, dirty yellow (pl. 4); vestiture of dorsum mostly pale, reclining. Similar in size and breadth of body to W. dicrastyli , but coloration in that species more nearly white, left paramere with anterior process arising in line with paramere shaft, and secondary endosomal strap with a very broad subbasal undulation. Breeds on Pityrodia and Cyanostegia spp. (Lamiaceae) .

DESCRIPTION: Male: Body very elongate ovoid, total length 5.13–5.46, ratio l/w 5 3.17. COLORATION (pl. 4): Pronotum unicolorous pale; hemelytron mostly pale; markings on cuneus present as partial infuscation; membrane with elongate, contrasting, fumose marking at extreme base, remainder weakly fumose over entire area, veins white; venter light green; 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 many brown or black spots; hind tibial spines dark with very small dark bases. SURFACE AND VESTITURE: Dorsum with reclining black setae, especially on pronotum, intermixed with pale setae on hemleytron, and with some sericeous or woolly setae. STRUCTURE: Head: Elongate, projecting anteriorly, ratio wh/lh 5 2.47 (fig. 27A); antennal fossa with ventral margin 1 diameter above ventral margin of eye; interocular space moderate, ratio iod/wh 5 0.45; eyes leaving gena moderately exposed in lateral view (hg3/he20); labium reaching to margin of pygophore. GENITALIA (fig. 27, D–F, 28): Endosoma: Base very long, with an open U-shaped bend; distal half of shaft smoothly curving; primary endosomal strap weakly elongate apically, ratio lae/lsg 1.67; 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, smoothly curving over entire length; secondary gonopore seen laterally in lateral view of endosoma. Phallotheca: More or less right angulate, dorsal surface with a hump; dorsal surface with a conspic- uous keel. Left Paramere: Body very elongate, greatly exceeding margin of pygophore; in dorsal perspective closed over about onehalf length; body not distinctly tapering

(AMNH_PBI 00129643).

toward apex; anterior process arising near middle or anterodorsal margin; anterior process directed vertically; posterior process appearing tubular, fingerlike; posterior process with strongly projecting shoulder at base; base of posterior process at least somewhat elevated above level of paramere body. Right Paramere: Body moderately elongate, ratio lrp/wrp 3.25; 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 Pityrodia R. Br. (Lamiaceae) .

HOSTS: Recorded from Pityrodia terminalis (Endl.) A.S. George (pls. 9D, 10A, B) and Cyanostegia angustifolia Turcz. (Lamiaceae) (pl. 10C, D). The single record from Newcastelia insignis E. Pritz. may be the result of commingling specimens in the field.

DISTRIBUTION (map 1): Know from the Goldfields region of Western Australia.

DISCUSSION: Pityrodia terminalis and Cyanostegia angustifolia are nearly sympatric in their distribution across the wheat belt of southwestern Western Australia. Thus, further collecting might show that W. pityrodii roughly conforms to the distribution of its hosts.
