Biromiris scheyville , new species Figure 13 ; plate 5

DIAGNOSIS: Recognized by relatively strong medial constriction of lateral hemelytral margins, only Australian Biromiris sp. with terete-shaped antennal segments 3 and 4, short segment 2, yellowish coloration of posterior apices of clavus (pl. 5), completely dark brown coxae, and large size.

DESCRIPTION: Male: Macropterous, medium sized, elongate, weakly medially constricted. Total length 3.56, width pronotum 1.06, maximum width across hemelytra 0.99. COL- ORATION: Head dark brown. Eyes silver. Antennal segment 1 golden, segment 2 golden basally and pale brown distally, segments 3 and 4 completely brown. Pronotum, scutellum and thorax dark brown. Scent gland paler than thorax. Legs: All coxae dark brown with white margin basal to joint with femora. Pro- and mesofemora pale brown, metafemora darker brown. All tibiae dark brown basally, golden distally, metatibiae also with parallel rows of dark spicules. Basal segments of tarsomeres golden, distally dark brown. Anterior margin of corium castaneous 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, dark margin extending across median of clavus (pl. 5). Remainder of hemelytron castaneous, lateral posterior margins of hemelytra completely opaque, reddish brown, and margin of corium and anterior of membrane darker brown, posterior apices of clavus yellowish. Over J of total area of cuneus white posterior to claval fracture, with lateral margins possessing yellowish tinge, occupying less than J total area of cuneus, posterior darker reddish brown than corium. Membrane dark brown with dark brown pigmentation around veins. Abdomen dark brown. STRUCTURE: Clypeus projecting beyond anterior margin of frons in lateral view, barely visible in dorsal view. Vertex weakly concave, width nearly 1.5 times width of one eye. Approximately M of total height of head below eyes. Antennal segments 3 and 4 terete shaped. 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 narrowed anteriorly and widening distally forming bell-shaped pronotum in dorsal view, lateral sides with narrow shelflike carina along medial line extending only on M length of pronotum and calli weakly visible. Scent gland less than J total area of metepimeron. Cuneus length approximately greater than M total length of hemelytral membrane. Abdomen narrow for most of length, expanding in diameter to pygophore. GENITALIA: Pygophore: Less than onefifth total length of abdomen. Remaining structures not examined.

Female: Unknown.

ETYMOLOGY: Named for the collecting locality of Scheyville; noun in apposition.

HOSTS: Myrtaceae ; from pyrethrum fogging of Eucalyptus .

DISTRIBUTION: Eastern New South Wales.

DISCUSSION: This species is only known from the male holotype and one other specimen from the same collecting event that is missing its head, pronotum, all appendages, and abdomen and therefore is not designated as a paratype.
