HOLOTYPE: AUSTRALIA: New South Wales: Ku-Ring-Gai Chase National Park, McCarrs Creek, West Head Rd., 33.66668 ° S 151.25 ° E, 100 m, 14 Oct 1995, Schuh and Cassis, Grevillea buxifolia (Sm.) R.Br. (Proteaceae) , 13 ( AMNH _PBI 00132267) ( AM).

DIAGNOSIS: Recognized by the large size, elongate and slightly ovoid body, uniformly pale yellowish green coloration, and characters of the male genitalia, most notably the large vesica, with dorsal apical process bladelike, with serration on exterior surface, process of square shape, median apical process treeshaped with numerous branches. Habitus similar to P. mina , but distinguished by vestiture and male genitalia, vesica most similar to P. galbanus and P. mina , but distinguished from both by the larger size of the vesica and distinguished from P. mina by the serration on the dorsal apical blade.

DESCRIPTION: Male: Large (3.45–3.89), elongate ovoid, length apex clypeus–cuneal fracture 2.12–2.47, width across pronotum 1.07–1.19. COLORATION ( fig. 2 ): General coloration very pale yellowish green, yellow suffusion most prominent on pronotum, mesonotum, and scutellum. Head: Uniformly greenish yellow, fasciae indistinct. Antenna pale, infuscate toward apex, segment 1 with subbasal dark ring. Labium pale, infuscate toward apex. Thorax: Pronotum, mesonotum, and scutellum uniformly pale yellowish green, apex of scutellum pale. Pleura pale greenish yellow. Legs: Legs pale with tarsi infuscate, all femora with small brown spots, tibial spines dark with irregular dark bases. Hemelytra: Corium and cuneus uniformly pale greenish yellow, membrane clear, sometimes with anterior cell and patch distal to cells infuscate, veins pale orange. Abdomen: Pale green, gradually turning to greenish yellow toward pygophore, dorsal surface of pygophore pale. SURFACE AND VESTITURE: Dorsum weakly shining, densely covered with moderately stout, suberect, dark, simple setae, and flattened, adpressed, silvery setae, the two types of setae of similar abundance. STRUCTURE: Head: Triangular in dorsal aspect, vertex slightly wider than one eye, clypeus produced, and maxillary plate sunken, eye large, almost as high as head. Antennal segment 1 slender and surpassing apex of head, segment 2 long and slender, slightly smaller diameter than segment 1, diameter slightly increased toward apex, segments 3 and 4 slender, segment 3 longer than segment 4. Labium slender, apex of labium reaching apex of metacoxa. Thorax: Pronotum wider than long and anterior margin slightly sinuate. Legs: Claws of moderate length and stoutness and pulvilli of moderate size. Hemelytra: Slightly convex laterally, cuneus elongate triangular. Abdomen: Stout, reaching to about middle of cuneus. GENITALIA: Parameres: Right paramere as in figure 7 ; left paramere ( fig. 9 ) with anterior process of medium length and thickness, posterior process long, slender, bent ventrad, and truncate at apex, body with large, almost horizontal lobe, slightly bent to the left. Phallotheca ( fig. 11 ): External portion irregularly tubular, tapering toward apex, anterior surface basally with large horizontal flange and distinctly serrate lobe subapically, posterior surface with weakly serrate very shallow flange, opening ventral, slitlike at base and extended toward apex. Vesica ( fig. 13 ): Large, with dorsal apical process blade-shaped and with exterior margin weakly serrate, proximal process square, large, medi- an apical process tree-shaped with numerous branches, weakly sclerotized, ventral apical process long and slender, not connected to strap of vesical body.

Female: Coloration similar to male, somewhat more faded; shorter than male and slightly more ovoid body. Total length 3.12– 3.50, length apex clypeus–cuneal fracture 2.10–2.28, width across pronotum 1.07–1.10.

ETYMOLOGY: Named for the type locality.

HOST (appendix 1): The single recorded host for this species is Grevillea buxifolia (Sm.) R.Br. (Proteaceae) .

DISTRIBUTION: Known from Ku-Ring-Gai Chase and Royal National Parks close to Sydney, in New South Wales ( fig. 17 ).

DISCUSSION: Closely related to P. manilla and the sister species P. australianus and P. galbanus according to the present analysis, based on the shape of the dorsal apical process of the male vesica.

Solid circles on the branches indicate uniquely derived apomorphic character states; empty circles indicate homoplastic characters under unambiguous character optimization. Figures above the bars indicate number of character as shown in table 2 and appendix 1; figures below bars indicate the character state. Large figures in shaded circles denominate clades.
