DIAGNOSIS: Recognized by predominately uniformly pale gray coloration with dusky orange to brown markings and strongly S-shaped endosoma with two straps separated by membrane, dorsal strap thin and terminating in small, subapical secondary gonopore; apex of ventral strap with slightly notched.

DESCRIPTION: MALE: Mean total length 3.36, mean pronotum width 0.92. COLORATION (pl. 1): Predominately pale gray with diffuse dusky pale orange to brown on head, antenna, calli, mesoscutum, base of scutellum in middle, legs, and pygophore with discrete markings on apex of clavus, distal medial border of corium, and distal edge of cuneus. SURFACE AND VESTI- TURE (fig. 3A, C, pl. 1): Dorsal vestiture mixed, with silvery shining, somewhat sericeous setae and brown or golden recumbent simple setae on hemelytron and cuneus. STRUCTURE: Head (figs. 3A, B, pl. 1): Transverse, separated from anterior margin of pronotum; eyes large, occupying practically entire head in lateral view; antenna inserted below ventral margin of eye by diameter of antennal segment 1, eyes strongly emarginate at fossa, antennal segment 2 long (1.05), approximately 1.50 times width of head; labium reaching base of mesocoxa. Thorax: Pronotum subconical, posterior margin straight. Pretarsus: Pulvilli absent (fig. 3E). Hemelytron: Elongate. GENITALIA (fig. 3F, pl. 7A–J): Pygophore: Cylindrical with ventroposterior surface slightly prominent; one or two long separated bristles ventrad of left paramere insertion. Endosoma: Strongly S-shaped, with two straps; dorsal strap very thin, terminates at secondary gonopore; ventral strap divided in middle by hyaline seam, apical region of strap large, elongate, and extending distad of secondary gonopore, apex of apical sclerite slightly notched with serrate and smooth sides. Secondary gonopore: Small, ringlike, subapical; aperture teardrop shaped, open caudally, adjacent to discrete distal sclerite of ventral strap. Phallotheca: Elongate, gradually attenuate to posterior apex, aperture relatively short; anterior margin short, reaching to middle of pygophore. Parameres: Left paramere: Diameter of posterior process strongly tapered with pointed apex; anterior process short, pointed, with a few long apical bristles. Right paramere: Very small, rounded, with small apical spine.

FEMALE (pl. 1): Coloration as in male; differing from male as in generic description; mean total length 3.16, mean pronotum width 0.93. GENITALIA (pl. 7K–M): Posterior margin of sternite 7: Concave medially. Ventral labiate plate: With faint platelike anteroventral extension just right of midline. Dorsal labiate plate: Nar- row longitudinally. Posteromedial region: With obvious concentric ribbing. Anterolateral region: Even with anterior margin of sclerotized rings. Posterior wall: Interramal sclerite: Not differentiated from connecting membrane.

ETYMOLOGY: Named for its multiple recorded hosts, all in the genus Eucalyptus . From the Greek polys, “many,” and phagein, “to eat.”

HOSTS: Recorded from the following Eucalyptus species : Eucalyptus camaldulensis , E. gamophylla , E. macrocarpa (pl. 38A, B), E. pleurocarpa (pl. 38C), E. sp., and E. tetragona ( Myrtaceae : Eucalypteae ).

DISTRIBUTION (map 1): Apparently widespread in desertic areas of central, southern, and western Australia. In Western Australia known from several collection events near Ravensthorpe on the southern coast of Western Australia, grounds of the Western Australian Herbarium, and Wheatbelt and Pilbara regions. Also found in Gammon Ranges of South Australia and central desert region of Northern Territory. Found in the widely separated southwestern, southwest interzone, Pilbara , and eastern desert phytogeographic subregions.
