TYPE SPECIES: Papuamiroides elongatus , new species.

DIAGNOSIS: Recognized by narrow and elongate antennal segment 2, shape of head, distinctly shiny head, thorax, pronotum, and scutellum, punctate and flat hemelytron with strongly constricted medial margin, patterning on hemelytron, and apex of endosoma in form of a spine.

DESCRIPTION: Male: Macropterous, large, medially constricted. Total length 2.77–2.82, width pronotum 0.71–0.75, maximum width across hemelytra 0.74–0.77. COLORATION: Brown, pale brown, and castaneous. Head: Castaneous. Eyes deep red to purple. Labium pale brown with distal darkening. Antennal segment 1 dorsally brown on distal half and golden for rest, segment 2 dark brown along margin with Antennal segment 1 and golden for over half of remaining length before transitioning to dark brown on distal M, segment 3 completely golden, segment 4 dark brown. Thorax: Pronotum, scutellum, and thorax castaneous, anterior margin of pronotum sometimes more golden. Dorsolateral margin of metepisternum and scent gland unicolorous with thoracic pleuron. Legs: Pro- and mesocoxae pale brown to castaneous, metacoxa dark basally for half of length and pale distally for remainder of length. All femora dark brown with paler brown ventrally, especially metafemur. All tibiae proximally dark brown, distally golden, metatibia with parallel rows of dark spicules along entire length. Basal tarsomeres golden, distally dark brown. Hemelytra: Primarily castaneous to dark brown with anterior of corium castaneous to golden brown, clavus castaneous with medial area darker brown, transparent areas on posterolateral margins adjacent to apex of clavus with dark posterior margin transversing entirety of hemelytron, white patch along medial margin of corium posterior to clavus and anterior hemelytral membrane surround- ed with dark brown margin, lateral corial margin narrowly dark brown, medially golden brown (pl. 7). Anterolateral margin of cuneus white for nearly J total area of cuneus, posterior dark brown. Membrane pale brown with veins lacking pigmentation. Abdomen: Sternite 1 yellowish with dark posterior margin, sternite 2 white to transparent, remaining segments dark brown. SURFACE AND VESTITURE: Dorsal surface of body and eyes covered with long, erect pale brown setae. Head, pronotum, and scutellum distinctly shiny. Hemelytron punctate, also with long, erect, evenly distributed black setae. Reflective patches on clavus and cuneus. STRUCTURE: Head: Wide and flat. Clypeus surpassing anterior margin of frons and barely visible in dorsal view. Vertex weakly convex, posterior margin shelflike, width nearly equal to width of one eye. Eye height greater than 1.5 total height of head, dorsal margins of eyes weakly removed from anterior margin of vertex, vertex visible in lateral view. Antennal segment 1 inverted-cokebottle shaped, length surpassing apex of head; segment 2 narrower than segment 1, increasing in diameter distally, length segment 2 equal to 1.5 times head width, segments 3 and 4 slender and less than half length of segment 2. Labial segment 1 not quite attaining posterior margin of head, apex of labium reaching apex of mesocoxa. Thorax: Pronotum 1.25 times as wide as long, with narrow, weakly reflexed collar. Mesoscutum hidden by posterior margin of pronotum, anterior portion of scutellum swollen. Scent gland approximately J total area of metepimeron. Legs: Moderate length, slender with metafemur weakly flattened. Claws of moderate length and width, pulvilli less than half of claw length. Parempodia parallel and setiform. Hemelytra: Lateral margins strongly medially constricted, dorsally flat. R+M vein terminating near midpoint of hemelytron. Cuneus triangular, lateral margin weakly swollen, occupied by white pigmentation, medial margin weakly convex, total length greater than M total length of hemelytral membrane, cuneal fracture angled anteromesially. Abdomen: Narrow anteriorly, widening posteriorly, petiolate. Abdominal sternite 1 longer than wide. GENITALIA (fig. 32): Pygophore: Small, less than J total length of abdomen, lacking any spines or elaborations. Endosoma: Small, slender, twisted, Sshaped, composed of two sclerotized straps, fused into tube toward base and separating over most of length, unified by membrane, and fusing at apex to form spinelike process. Secondary gonopore small, weakly sclerotized, located subapically (fig. 32A). Phallotheca: Moderately sized, L-shaped, apex gently tapering to a point, ventral surface expanded preapically (fig. 32D). Right Paramere: Moderately sized, nearly equal in size to left paramere, lateral margins nearly parallel, with tapering, pointed apex (fig. 32B). Left Paramere: Moderately sized; posterior process of medium width, with sensory pits, dorsal surface nearly straight, apex directed perpendicular to base of paramere, relatively elongate compared to anterior process, anterior process short, dorsal margin near median of total height of paramere. Body between anterior and posterior processes rounded (fig. 32C).

Female: Brachypterous, small, medially constricted. Total length 2.52–2.62, width pronotum 0.60–0.69, maximum width across hemelytra 0.69–0.74. COLORATION: Similar patterning as in male. SURFACE TEXTURE AND VESTITURE: As in male. STRUCTURE: Clypeus produced, exserted in dorsal view. Vertex convex, width greater than two times width of one eye. Eyes nearly half total height of head in lateral view, dorsal surface of eyes continuous with vertex. Length of antennal segment 2 nearly 1.33 times total head width. Pronotum weakly medially constricted in dorsal view, lateral margins of anterior lobe narrower than posterolateral margins. Apex of hemelytron not attaining apex of abdomen. Abdomen: Petiolate, anterior half sharply declining ventrally in lateral view and constricted relative to posterior half in dorsal view, posterior half sloping dorsally. Spine absent on ventral surface of ovipositor apex, ovipositor continuously linear. GENITALIA: Not examined.

ETYMOLOGY: Name for the similar appearance to Papuamimus ; masculine.

HOSTS: Unknown.

DISTRIBUTION: Papua New Guinea.

DISCUSSION: Papuamiroides is similar to Papuamimus in overall appearance and morphology, however, the narrow and elongate antennal segment 2 and the form of the male genitalia separate the two genera. Furthermore, in the closely related genera Arafuramiris , Missanos , and Waterhouseana , the length of the antennal segment 2 is never more than 1.3 times greater than the width of the head whereas it is 1.5 times in Papuamiroides .
