Biromiris enarotadi Schuh, 1984: 209 , figs. 686, 689–698 (n. sp., diag., descr., DV, figs. headpronotum, MG, SEM).

DIAGNOSIS: Recognized by relatively wide vertex, orange-castaneous coloration (pl. 5), large size, and relatively weakly swollen pronotum.

REDESCRIPTION: Male: Macropterous, medium to large sized, elongate, medially constricted. Total length 3.56, width pronotum 1.03, maximum width across hemelytra 0.99. COLORATION: Head pale orange brown. Eyes dark purple. Labium completely orange. Antennal segments missing in specimen examined, however in original description cited as Antennal segment 1 completely golden to golden basally, dark distally, segment 2 brown, segments 3 and 4 completely brown. Pronotum, scutellum, and thorax orange-brown. Scent gland unicolorous with thoracic pleuron. Procoxae golden orange, mesocoxae golden, metacoxae dark red. Pro- and mesofemora golden, metafemora mostly dark red excluding apex with tibiae where golden. All tarsomeres golden. Hemelytra orange-castaneous, with partial transparent transverse fascia on anterior margin of hemelytron possessing dark posterior margin, occupying wide band across median of anterior margin of corium. Posterior lateral margins of corium weakly transparent posterior to median of hemelytron, transitioning into reddish-castaneous color anterior to cuneal fracture (pl. 5). Over M of total area of cuneus posterior to cuneal fracture white, posterior dark reddish brown to brown. Membrane pale brown with weak dark brown pigmentation on veins. Abdomen brown. STRUCTURE: Clypeus flush with frons in lateral view, barely visible in dorsal view. Vertex flat, width greater than width of one eye. Cyberial muscle attachment sites visible on frons. Eyes weakly removed from anterior margin of vertex, vertex partially visible in lateral view by anterior surface of eyes, eyes greater than half of total height of head, and posterior margin of eyes obscure anterior margin of pronotum. Approximately J of total height of head below eyes. Length of antennal segment 2 greater than 1.5 times total head width to two times head width. Antennal segments 3 and 4 terete. Apex labium reaching mesocoxa. Pronotum less than two times as wide as long, dorsal surface weakly swollen dorsally and convex, without dorsal indentation separating anterior and posterior lobes, lateral margins nearly straight, forming almost trapezoidal-shaped pronotum in dorsal view, lateral sides with thin, carinalike ridge along medial line ( Schuh 1984: fig. 691). Scent gland less than J total area of metepimeron. Cuneus length approximately less than M total length of hemelytral membrane. GENITALIA: Pygophore: Large, with ventral surface nearly flat and anterior surface declining, M total length of abdomen. Endosoma: Large, slender at base and wider at apex, twisted, S-shaped, composed of two sclerotized straps, fused into tube toward base and separating toward apex, unified by membrane. Secondary gonopore small, weakly sclerotized, located at apex of endosoma. Phallotheca: C-shaped, relatively short at base, apex tapering to narrow point ( Schuh 1984: fig. 760). Right Paramere: Not examined. Left Paramere: Moderately sized; posterior process relatively wide, wider than base of paramere, with sensory pits, directed ventrally with concave curvature along dorsal margin, relatively elongate compared to anterior process; anterior process stout but without sensory pits on interior margin, dorsal surface subequal to midline of total height of paramere; dorsal surface of median portion between anterior and posterior processes convex ( Schuh 1984: fig. 759).

Female: Unknown.

HOSTS: Unknown; collected at light trap.

DISTRIBUTION: New Guinea; Queensland, Australia.

DISCUSSION: The specimen examined from Queensland is nearly identical to the paratypes from Papua New Guinea except is larger in size and paler in coloration, the latter likely due to fading. Therefore, we consider it conspecific, and include a redescription of the species as part of the emphasis on Australian Leucophoropterini .
