Figure 43, map 10, table 1, plates 14, 15

DIAGNOSIS: Recognized by large size, pale coloration (pl. 14), strongly twisted J-shaped endosoma with an elongate curved, sharp apical spine of moderate length, a folded sclerotized plate supporting dorsal aspect of a discrete billowy membranous sac laterad of secondary gonopore (fig. 43, pl. 15), and left paramere with medial portion of dorsoposterior margin conspicuously elevated (fig. 43). Most similar in size to G. forrestii , G. lasseteri , and G. symondsae , but endosomal structure distinctive with discrete membrane sac adjacent to secondary gonopore (pl. 15).

DESCRIPTION: Male: Mean total length 5.19, mean pronotum width 1.21. COLORA- TION (pl. 14): Light green to pale, hemelytron cloudy; corium with a diffuse dark spot at inner angle of cuneus; membrane weakly fumose, with a weak dark spot at apex of cells. SURFACE AND VESTI- TURE (pl. 14): Vestiture of reclining, dark, common setae. STRUCTURE: Head (pl. 14): Eye occupying two-thirds height of head; antenna inserted just above ventral margin of eye, eye very weakly emarginate; antennal segment 2 moderately long (1.37), 1.48 times width of head; labium reaching posterior margin of mesosternum. Thorax (pl. 14): Mesoscutum moderately exposed. Hemelytron: Greatly elongate, costal margin nearly straight, cuneus long. GENITALIA (fig. 43, pl. 15): Pygophore: Moderate in size. Endosoma: Moderately large, J-shaped, tightly twisted; ventral strap terminating as a large curved solitary spine; dorsal strap terminating with large thin, weakly folded sclerite forming support of billowy membranous bag dorsad of secondary gonopore. Phallotheca: Apical portion elongate and narrow, conical; aperture on anterior dorsoapical aspect, elongate ovoid; basal portion long, reaching anteriad to three quarters length of pygophore in situ. Parameres: Left paramere with dorsoposterior margin strongly produced and narrowed to medial prominence; anterior process long, relatively large, and narrow. Right paramere moderately large, irregularly lanceolate, with a well-developed point on posterior angle.

Female (pl. 14): Coloration as in male; differing from male as in generic description; mean total length 4.33, mean pronotum width 1.21.

ETYMOLOGY: Named after one of the known hosts, Eremophila pantonii (Scrophulariaceae) .

HOSTS: Recorded from Eremophila oppositifolia and E. pantonii (Scrophulariaceae) .

DISTRIBUTION (map 10): Known from the area of the Charles Darwin Nature Reserve, Western Australia, about 350 km NNE of Perth.
