Austroplagiognathus arbustoides , new species

Figure 6, map 3, table 1, plate 3

DIAGNOSIS: Recognized by body form, conspicuously

the elongate

green head,

pronotum, and scutellum, swollen posterior lobe of the pronotum, hemelytron with strongly infuscate spots at inner angle of the cuneus and at the apex of the membrane cells, strongly infuscate membrane, and structure of the male genitalia; endosoma with two apical spines of structure similar to that seen in Plagiognathus arbustorum (Fabricius) , but also with a shorter spine extending from the distal margin of the secondary gonopore by about the length of the gonopore.

DESCRIPTION: MALE: Total length 5.70, pronotum width 1.38. COLORATION (pl. 3): Head, pronotum, and scutellum distinctly green; mesoscutum orange; corium, clavus, and cuneus almost transparent, weakly infuscate, membrane rather strongly infuscate; otherwise as in generic description. SURFACE AND VESTITURE (pl. 3): As in generic description. STRUCTURE: Head (pl. 3): Eyes relatively large, vertex narrow; eye occupying just less than threequarters of height of head; antenna inserted above ventral margin of eye by diameter of fossa, eye not emarginate; antennal segment 2 long (1.50), 1.65 times width of head; labium reaching posterior apex of procoxa. Thorax (pl. 3): Posterior lobe of pronotum distinctly swollen, lateral margins convex. Hemelytron: Distinctly elongate. GENITA- LIA (fig. 6, pl. 3): Pygophore: Elongate.

Endosoma: Distal portion slightly bent to left; dorsal and ventral straps moderately long; ventral strap bifid with long and short spine distad of secondary gonopore, short spine situated medial to long apical spines, long spine of dorsal strap with extensive membrane forming dorsal surface; long apical spines of equal length. Phallotheca: Broad with large ventral outpocket basally and strong internal ridge; aperture ovoid. Parameres: Left paramere with dorsoposte ‐ rior margin moderately elevated, posterior process straight, anterior process minute.

Right paramere moderately large, apex with one point and a lateral prominence.

FEMALE: Unknown.

ETYMOLOGY: Named after Plagiognathus arbustorum , the type species of Plagiog ‐ nathus, in recognition of the similarity of appearance of the endosoma in the two species.

HOST: Recorded from Eremophila clarkei (pl. 37D, E) ( Scrophulariaceae ).

DISTRIBUTION (map 3): Known only from the Charles Darwin Nature Reserve, the type locality in Western Australia, about 350 km NNE of Perth.

HOLOTYPE: AUSTRALIA: Western Australia: Charles Darwin Reserve, granite outcrop SW of homestead, 29.59261°S 116.94791°E, 312 m, 21 Sep 2009, C. Symonds, Eremophila clarkei A.F. Oldfield & F. Muell. (Scrophulariaceae) , det. WA Herbarium, 1♂ (AMNH_PBI 00414631) (WAMP).
