Biromiris binjour , new species Figure 13 ; plates 4, 8

DIAGNOSIS: Recognized by characters in generic description, small size, dark-maroon

to brown coloration (pl. 4), lack of terete antennal segments 3 and 4, wide vertex, and broad pronotal carina almost shelflike on lateral margins.

DESCRIPTION: Male: Macropterous, medium sized, elongate, weakly medially constricted. Total length 3.12, width pronotum 1.01, maximum width across hemelytra 0.99. COLORATION: Head brown. Eyes silverish. Labium brown with medial area paler. Antennal segment 1 golden, segment 2 golden basally for first third, orange-brown medially for middle third, brown distally for last third, antennal segment 3 mostly yellow-orange basally for approximately L of total length and brown distally, antennal segment 4 completely brown. Pronotum, scutellum, and thorax castaneous with posterior margin of pronotum dark brown. Scent gland same as thorax. Procoxae dark reddish with white margin basal to joint with profemora, mesocoxae brown basally, transparent white for remainder of length, metacoxae dark basally and pale distally at margin with metafemora. Pro- and mesofemora brown, metafemora deeper brown red. Anterior margin of corium dark brown along with anterior half of clavus transitioning into transparent partial fascia with dark brown margin that takes up M of total area of anterior portion of corium (pl. 4). Remainder of hemelytron dark brown, lateral posterior margins of hemelytra completely opaque, reddish brown. Over M of total area of cuneus white posterior to claval fracture, occupying less than M total area of cuneus, posterior darker reddish brown than corium. Abdomen brown. STRUCTURE: Clypeus projecting beyond anterior margin of frons in lateral view, barely visible in dorsal view. Vertex flat, with posterior margin raised for medial half and lateral margins declining forming shelflike appearance, width nearly two times width of one eye. Approximately M of total height of head below eyes. Length of antennal segment 2 greater than 1.33 times total head width to two times head width, weakly curving medially. Antennal segments 3 and 4 slender. Labial segment 1 apex past posterior margin of head, apex of segment 4 reaching apex of metacoxa. Pronotum less than two times as wide as long, dorsal surface swollen dorsally and convex, without dorsal indentation separating anterior and posterior lobes, dorsal lateral margins nearly straight, forming almost trapezoidal-shaped pronotum in dorsal view, lateral sides with broad shelflike carina along medial line with anterior lobes visible dorsally as lateral extensions. Cuneal length approximately less than M total length of hemelytral membrane. GENITALIA: Not examined.

Female: Unknown.

ETYMOLOGY: Named for the collecting locality of Binjour Plateau; a noun in apposition.

HOSTS: Unknown: vine scrub, pitfall trap.

DISTRIBUTION: Southeast Queensland.

DISCUSSION: This species has the pronotal carina as a broad ridge, unlike the narrow ridge found in most species of Biromiris . It is known only by the holotype.

HOLOTYPE: AUSTRALIA: Queensland: Binjour Plateau, Swains Rd , 25.53333 ° S 151.5 ° E, 340 m, 23 Sep 1997 – 21 Dec 1997, Cook and Monteith. 18 (00291236) ( QM).
