Gyrophallus darwinensis , new species

Figure 37, map 9, table 1, plates 12, 13

DIAGNOSIS: Recognized by its small size, diffuse dark markings on apex of corium and on membrane (pl. 12), small J-shaped endosoma with one narrow, reflected apical spine, and a long sclerotized plate supporting membranous sac on dorsoapical surface of endosoma (fig. 37, pl. 13). Gyrophallus darwinensis smaller than congeners and endosomal structure also distinctive.

DESCRIPTION: Male: Mean total length 3.64, mean pronotum width 0.98. COLORATION (pl. 12): Light green to pale, mesoscutum yellow, hemelytron translucent; corium with a weak dark spot at inner angle of cuneus; membrane at most weakly fumose, with a weak spot at apex of cells. SURFACE AND VESTITURE (pl. 12): Vestiture of reclining, dark, common setae. STRUCTURE: Head (pl. 12): Eye occupying slightly less than two-thirds height of head; antenna inserted just above ventral margin of eye, eye weakly emarginate above insertion; antennal segment 2 relatively short (0.91), 1.15 times width of head; labium reaching between midpoint and posterior margin of mesosternum. Thorax (pl. 12): Mesoscutum broadly exposed. Hemelytron: Weakly elongate, costal margin weakly convex, cuneus relatively short. GEN- ITALIA (fig. 37, pl. 13): Pygophore: Moderate in size. Endosoma: Small, J-shaped; dorsal strap bifid, forming slender, recurved, apical spine and wide, weakly sclerotized apical shroud; ventral strap bifid with slender, overlapping spines, one longer and thicker than other, both shorter than spine of dorsal strap. Phallotheca: Apical portion narrow; aperture elongate with undulating margin on anterior dorsoapical and apical aspect; basal portion reaching one-half length of pygophore in situ. Parameres: Left paramere relatively small, dorsoposterior region strongly inflated medially; posterior process short; anterior process truncate. Right paramere moderately large; apically truncate, with small point on anterior angle.

Female (pl. 12): Coloration as in male; differing from male as in generic description; mean total length 3.11, mean pronotum width 0.93.

ETYMOLOGY: Named for the Charles Darwin Reserve, Western Australia, the type locality.

HOSTS: Recorded from Eremophila clarkei (pl. 37D, E) and E. miniata (Scrophular ‐ iaceae).

DISTRIBUTION (map 9): Known from the Charles Darwin Nature Reserve, about 350 km NNE of Perth, Western Australia.
