Collessicoris Carvalho and Gross, 1982: 53 (n. gen., descr.).

TYPE SPECIES: Collessicoris bellissimus Carvalho and Gross, 1982 , by original designation.

DIAGNOSIS: Recognized by relatively flat, wide head, yellow transverse fascia in addition to white transverse fascia (pl. 5), presence of long, erect setae without hemelytral punctation, and flat hemelytral margins. Female recognized by wide head nearly as wide as width of posterior margin of pronotum, clublike antennal segment 2, and brachypterous hemelytra.

REDESCRIPTION: Male: Macropterous, medium sized, elongate, weakly medially constricted. Total length 2.92–3.07, width pronotum 0.88–0.89, maximum width across hemelytra 0.92–0.94. COLORATION: Brown, pale brown, and castaneous. Head: Brown. Eyes deep red to purple. Labium brown with medial paler. Antennal segment 1 golden, segment 2 golden basally brown distally, segment 3 pale basally for approximately one-eighth of total length and brown distally, segment 4 completely brown. Thorax: Pronotum, scutellum, and thorax dark brown. Dorsolateral margin of metepisternum and scent gland with relatively narrow orange-yellow band, width equal to about J of total width of scent gland. Legs: Pro- and mesocoxae brown basally for most of length golden distally at joint with femora, metacoxa dark basally for half of length and pale distally for remainder of length. Profemur brown basally and lightening to pale brown distally, meso- and metafemora brown. Pro- and mesotibiae basally dark brown, distally golden, with metatibia pale at joint with metafemur, dark brown for remainder of apical half and then transitioning back to golden for remainder of proximal half, with parallel rows of dark spicules along entire length. Basal tarsomeres golden, distally dark brown. Hemelytra: Anterior margin of corium dark brown along with anterior half of clavus transitioning into transparent complete fascia occupying up M of total area of anterior portion of corium and thin strip at median of clavus but not extending medially to claval suture (pl. 5). Posterior to transverse fascia dark brown margin extending across entire width of hemelytron, followed by yellowish-gold diffuse transverse fascia also extending across entirety of hemelytron anterior to midpoint. Posterior area of corial margin with lateral transparent areas, remainder of corium dark brown. Over M of total area of cuneus white posterior to claval fracture with yellowish tinge at lateral margins, posterior dark reddish brown. Membrane pale brown. Abdomen: Brown. SURFACE AND VESTITURE: Dorsal surface of body and hemelytron covered with long, erect pale brown setae. Medial portion of hemelytron and midpoint of claval suture with reflective patches. STRUCTURE: Head: Relatively flat anteroposteriorly, dorsally clypeus weakly visible, barely surpassing frons anteriorly in dorsal view. Cyberial muscle attachment sites visible on surface of frons. Area of head below eyes in anterior view relatively wide and short. Vertex flat, with posterior raised for medial half and lateral margins declining, forming shelflike appearance, width greater than width of eye. Eyes nearly continuous with anterior margin of vertex. Eye height greater than 1.5 total height of head, vertex visible in lateral, posterior margin of eyes obscures anterior margin of pronotum. Nearly M of total height of head below eyes, gula short, flat. Antennal segment 1 inverted-coke-bottle shaped, length surpassing apex of head; segment 2 long and narrower in diameter than segment 1, increasing in diameter distally toward segment 3. Length of antennal segment 2 nearly 1.5 times total head width, weakly curving medially. Antennal segments 3 and 4 slender and less than half length of segment 2. Labrum narrow. Labial segment 1 exceeding posterior margin of head, apex of segment 4 extending past apex of mesocoxa. Thorax: Pronotum less than two times as wide as long, weakly swollen dorsally on posterior lobe, but without dorsal indentation separating anterior and posterior lobes, lateral margins angled, straight, forming trapezoidal-shaped pronotum in dorsal view. Anterior margin with thin, partially reflexed collar. Mesoscutum hidden, scutellum elevated anteriorly compared to posteri- or portion, whole structure transversely round- ed. Scent gland greater than a third of total area of metepimeron. Legs: Elongate, rounded, metatibia convexly curved near median and weakly laterally compressed medially. Claws of moderate length and width, pulvilli less than half of claw length. Parempodia parallel and setiform. Hemelytra: Elongate, lateral margins weakly constricted medially and posterior margins wider than posterior margin of pronotum, hemelytra flat on dorsal surface of body and not obscuring lateral margins of thorax and abdomen. Lateral margin of corium anterior cuneal fracture swollen and elongated, forming lobelike structure. Cuneus triangular, length slightly greater than M total length of hemelytral membrane, cuneal fracture angled anteromesially, and with partial thickening on lateral margins of cuneus in area occupied by white margin. Abdomen: Narrow, elongate. GENITALIA: (fig. 18): Pygophore: Small, unelaborated, occupying about onefifth length of abdomen, ventral margin weakly sloping upward toward apex. Endosoma: Small, slender, twisted, S-shaped, composed of two sclerotized straps, fused into tube toward base and separating toward apex, unified by membrane. Secondary gonopore apical, small, horse-collar shaped (fig. 18A). Phallotheca: Fairly small, Cshaped, apex gently tapering to a point (fig. 18D). Right Paramere: Moderately sized, smaller than left paramere, expanded to one side at base, tapering to pointed apex (fig. 18C). Left Paramere: Moderately sized; posterior process narrow and with dorsal margin medially convex, gently curving anteriorly, relatively elongate compared to anterior process, and with sensory pits; anterior process stout, dorsal surface far removed from posterior process and median of total height (fig. 18B).

Female: Brachypterous, medium sized, medially constricted. Total length 2.72–2.92, width pronotum 0.82–0.88, maximum width across hemelytra 0.81–0.89. COLORATION: Similar patterning as in male, but with larger portion of anterior segment 2 yellow and more of total area of cuneus white. SUR- FACE TEXTURE AND VESTITURE: As in male. STRUCTURE: Head: Head much wider than in male, nearly equal in width to posterior margin of pronotum and wider than width of anterior margin. Clypeus produced, exserted in dorsal view. Vertex convex, width two times as wide as width of one eye. Eyes approximately half total height of head in lateral view, dorsal surface of eyes continuous with vertex. Gula short, flat, and more developed than in male, greater than M total height of head below eyes. Antennal segment 2 long and more slender than segment 1 at basal joint with antennal segment 1, increasing in diameter distally toward segment 3, clublike. Length of antennal segment 2 just longer than total head width. Thorax: Pronotum less than two times as wide as long, anterolateral margins nearly straight and forming box shape in dorsal view. Mesoscutum and anterior margin of scutellum hidden by posterior margin of pronotum, scutellum weakly transversely rounded. Hemelytra: Apex subapical to posterior margin of abdomen, lateral margins weakly medially constricted. Cuneus shorter than in male, fracture angled anteromesially. Abdomen: Parallel sided, anterior half sharply declining ventrally, posterior half of abdomen parallel to dorsal surface of abdomen. Ovipositor spine present. GENI- TALIA (fig. 44R–S): Two relatively large, separate, triangular-shaped vestibular sclerites, lateral tube absent, narrow apical sclerite over vulva between two vestibular sclerites, sclerotized areas present on lateral margins of first gonapophyses between dorsal and ventral labiate plates, sclerotized rings weakly sclerotized (fig. 44R). Posterior wall mostly membranous, with posterior margin sclerotized and flat, lateral region of interramal sclerite sclerotized (fig. 44S).

HOSTS: Goodeniaceae .

DISTRIBUTION: Southeastern Australia.

DISCUSSION: Only the type species C. bellissimus is currently known for this genus. This taxon is distinctive compared to all other Leucophoropterini in color patterning and the shape of the head and pronotum in males and females (pl. 5).
