golden, distally dark brown. Hemelytra: Pale brown, with anterior margin of clavus abutting scutellum darker, chocolate brown. Posterolateral margins of corium distally dark brown with small transparent areas situated at level with posterior apex of claval suture. Anterior margins of cuneus posterior to cuneal fracture mostly transparent with interior margin lateral to cuneus pigmented yellowish white, posterior portion of cuneus dark brown (pl. 1). Membrane dark brown with weak brown pigmentation along wing veins. Abdomen: Dark brown, abdominal segments 3 and 4 paler brown to white. SURFACE AND VESTITURE: Dorsal surface of body and hemelytron covered with long, erect pale brown setae, hemelytron punctate and also possessing short and golden metallic across surface and patch of long, sericeous setae on anterior portion of clavus and in small patch posterior to apex of claval commissure. STRUCTURE: Head: Clypeus anterior to anterior margin of frons or flush with frons in lateral view, either visible in dorsal view or hidden, frons convex to flat. Cyberial muscle attachment sites visible on frons. Vertex flat or concave, with posterior margin raised for medial half and lateral margins declining, forming shelflike appearance, width equivalent to approximately half total width of one eye to two times width of one eye. Eyes weakly to strongly removed from anterior margin of vertex, vertex hidden or visible in lateral view by anterior surface of eyes, and eyes greater than L total height of head in lateral view to total height of head, posterior margin of eyes obscure anterior margin of pronotum. Gula obsolete. Antennal segment 1 inverted-cokebottle shaped, length surpassing apex of head, segment 2 long and wider in diameter than segment 1, increasing in diameter distally toward segment 3 and total length nearly equal to head width to 1.33 times total width head, weakly curving medially, segments 3 and 4 equal in width to base segment 2, less than half length of segment 2. Labrum narrow. Labial segment 1 apex past posterior margin of head, apex of segment 4 extending past procoxae to nearly reaching mesocoxae. Thorax: Pronotum greater than O as long as wide, dorsal surface flat along anterior lobe, swollen dorsally and convex on posterior lobe of pronotum, with dorsal indentation separating anterior and posterior lobes, dorsal lateral margins narrowed anteriorly and widening distally forming bell-shaped pronotum in dorsal view, length of anterior portion of pronotum well differentiated from posterior lobe and varying in length. Narrow and reflexed pronotal collar present. Mesoscutum hidden by posterior margin of pronotum, scutellum swollen medially and anteriorly posterior margin of pronotum. Scent gland less than M total area of metepimeron. Legs: Elongate, narrow, metafemur widening in diameter distally anterior to joint to metatibia forming kneelike appearance. Claws of moderate length and width, pulvilli less than half of claw length. Parempodia parallel and setiform. Hemelytra: Elongate, lateral margins strongly constricted medially, anterolateral margins narrower than posterior lateral margins or vise versa, hemelytra flat. R+M vein terminating early near median of hemelytron. Cuneus narrow, triangular, with lateral margins weakly curving convexly, length greater than M total length of hemelytral membrane, cuneal fracture angled anteromesially. Abdomen: Narrow for most of length, expanding in diameter to pygophore to form petiolate shape, abdominal sternite 1 longer than wide. GENITALIA: Pygophore: Small, less than one-fifth total length of abdomen, without elaborations, ventral surface nearly parallel to anterior surface. Endosoma: Relatively small, slender, twisted, S-shaped, composed of two sclerotized straps, fused into tube toward base and separating toward apex into two separate processes, posterior process angled in different direction from anterior process, anterior process with horse-collar shaped secondary gonopore located subapically (fig. 5A, E). Phallotheca: Apex broadly tapering toward point, main body elongate and nearly perpendicular to apex forming an L shape (fig. 5D) or curved relative to apex forming C shape (fig. 5G), sometimes with ridges on anterior margin of posterior process. Right Paramere: Moderately sized, smaller than left paramere, relatively elongate, and nearly parallel sided (fig. 5C). Left Paramere: Moderately sized; posterior process of intermediate width to wide, with sensory pits, and gently curving ventrally; anterior process stout but without sensory pits on interior margin, dorsal surface of anterior process near median of total height of paramere (fig. 5F) to nearly equal in height to dorsal surface of posterior process (fig. 5B); dorsomedial margin between anterior and posterior processes either rounded (fig. 5F, Schuh 1984: fig. 677) or with dorsal surface of posterior process raised relative to median of two processes forming convex margin (fig. 5B).

Female: Macropterous, small, medially constricted. Total length 2.67–3.12, width pronotum 0.89–0.99, maximum width across hemelytra 0.84–1.03. COLORATION: Primarily castaneous, similar patterning as in male except segment 2 more yellow basally, segment 3 distally dark brown, segment 4 mostly dark brown, and abdomen darker brown than head and thorax. SURFACE TEXTURE AND VESTITURE: As in male. STRUCTURE: Clypeus extending past anterior margin of frons, weakly visible in dorsal view, frons more convex than in male. Vertex convex, nearly two times width of one eye to two times width, eyes not total height of head in lateral view. Length of antennal segment 2 nearly equal to total head width. Abdomen petiolate, anterior half posterior from thorax sharply declining ventrally in lateral view and constricted relative to posterior half in dorsal view, posterior half of abdomen sloping dorsally. Lateral margins of abdomen sometimes wider than lateral margins of hemelytron. Spine absent on ventral surface of ovipositor. Ovipositor spine absent. Remaining characters as in male. GENITALIA (fig. 44E–G): First gonapophyses with two relatively large, separate, triangular-shaped sclerotized vestibular plates, no visible lateral tube, but with relatively broad apical sclerite covering vulva (fig. 44E): lateral margins of first gonapophyses sclerotized between dorsal and ventral labiate plates; sclerotized rings weakly sclerotized (fig. 44E). Posterior wall mostly membranous, with posterior margin sclerotized and possessing an additionally sclerotized medial plate (fig. 44F) forming medial pro- jection in posterior view (fig. 44G). Lateral areas of interramal sclerite sclerotized (fig. 44F).

HOSTS: Cupressaceae and Euphorbiaceae .

DISTRIBUTION: Papua New Guinea, Northern Australia (Northern Territory, Queensland) (fig. 4).

DISCUSSION: Arafuramiris is relatively easy to recognize due to the possession of the long sericeous setae on the clavus, which are not present in any other Leucophoropterini . Previously only described from the Indo- Pacific, three new species are here described from Northern Australia.
