DIAGNOSIS: Recognized by large size, large Jshaped endosoma with wide middle and strongly intertwined straplike distal sclerites supporting an extensive billowy membrane, two terminally overlapping strongly curved apical spines (fig. 41, pl. 13), and an elongate right paramere (fig. 41). Most similar in size to G. forrestii , G. pantonii , and G. symondsae , but broad medial area and flattened, curved, overlapping apical spines of endosoma distinctive (pl. 13).
DESCRIPTION: Male: Total length 4.83, pronotum width 1.31. COLORATION (pl. 12): Green to yellow, hemelytron translucent; corium with an intense dark spot at inner angle of cuneus; membrane weakly fumose, with a small dark spot at apex of cells. SUR- FACE AND VESTITURE (pl. 12): Vestiture of reclining, dark, common setae. STRUCTURE: Head (pl. 12): Eye occupying about two-thirds height of head; antenna inserted just above ventral margin of eye, eye weakly emarginate; antennal segment 2 relatively long (1.34), 1.4 times width of head; labium very short, reaching to apex of procoxa. Thorax (pl. 12): Mesoscutum broadly exposed. Hemelytron: Greatly elongate, costal margin weakly convex, cuneus long. GENITALIA (fig. 41, pl. 13): Pygophore: Large and elongate. Endosoma: Large, Jshaped with well-sclerotized undulating margins, two large, tightly intertwined, strongly curved apical spines, one formed by each strap, and a large membranous bag on distoventral surface supported by a sclerotized process arising near base of secondary gonopore; secondary gonopore subapical.
Phallotheca: Apical portion short and broadly conical; aperture on anterior dorsoapical aspect, relatively large ovoid; basal portion reaching anteriad to one-half length of pygophore in situ, right side with narrow sclerotized strap. Parameres: Left paramere large; dorsoposterior margin inflated with median bulge in dorsal view, with sharp apex of anterior process. Right paramere elongate, apically truncate with two points, posterior point prominent.
Female (pl. 12): Coloration as in male; differing from male as in generic description; mean total length 4.70, mean pronotum width 1.31.
ETYMOLOGY: Named after D.H. Lasseter, the Central Australian gold prospector, and the localities named after him.
HOST: Recorded from Eremophila longifolia (pl. 38F, G) ( Scrophulariaceae ). We posit that one specimen recorded on Grevillea stenobotrya (Proteaceae) is mislabeled and should read E. longifolia , which our field data indicate was documented as a host at the same site as G. stenobotrya .
DISTRIBUTION (map 10): Known from the Alice Springs region of Central Australia and northern South Australia.
