Ausejanus macrozonata (Carvalho and Gross) , new combination Figure 7 ; plate 3

Leucophoroptera macrozonata Carvalho and Gross, 1982: 23 , fig. 117 (n. sp., descr., disc., DV).

DIAGNOSIS: Recognized by deep red hemelytral coloration, burgundy-brown head, thorax, pronotum, and scutellum, white pigmentation in complete transverse fascia; and completely dark red pro-, meso- and metafemora. Females further recognized by being only Ausejanus species with nearly completely white anterior portion of hemelytron with burgundy to brown posterior (pl. 3).

REDESCRIPTION: Male: Macropterous, medium sized, elongate, and parallel sided. Total length 2.97, width pronotum 0.88, maximum width across hemelytra 0.99. COLORA- TION: Maroon to burgundy, hemelytra primarily burgundy with transverse, white pigmented fascia on anterior portion. Head dark to medium brown. Antennal segments 2, 3, and 4 gold, segments 2 gold basally, dark distally. Labium gold basally, brown distally. Eyes ruby red to dark red. Thorax, pronotum, and scutellum dark burgundy, Dorsolateral margin of metepisternum with thin yellow margin. All coxae dark red to burgundy. Pro- and mesofemora dark burgundy with gold coloration at joint with tibiae, metafemora completely dark red to burgundy. Tibiae gold, metatibia with parallel rows of dark spicules. Basal tarsomeres light, distally dark brown. Hemelytra primarily burgundy with complete yellowish-white transverse fascia on anterior portion containing white pigmentation in portion that transverses clavus and interior margins of corium (pl. 3). Cuneus white along fracture with an orange lateral margin, coloration extending approximately M of total area, remainder of cuneus dark red to brown. Abdomen burgundy. STRUC-

TURE: Eyes in lateral view nearly encompass total height of head, vertex width greater than width of an eye. Length of antennal segment 2 slightly shorter than 1.25 times total head width. Remaining structural characteristics as in generic description.

GENITALIA: As in generic description.

Female: Macropterous. Total length 2.52– 2.57, width pronotum 0.84–0.88, width at widest part of wings 1.04–1.06. STRUC-

TURE: Vertex takes up over half total head width. Segment 2 nearly 1.10 times total head width. COLORATION: Same coloration as male with exception of hemelytron and dorsolateral surface of metepisternum. Anterior portion of corium and clavus nearly completely pigmented white from median of hemelytron to just subapical of bases and interior margins abutting scutellum which transition into gold brown (pl. 3). Females also with at least anterior half of cuneus and greater portion of dorsolateral surface of hemelytron white.

HOSTS: Acacia leptostachya Benth (Fabaceae) . Also collected at lights.

DISTRIBUTION: Western Australia and Queensland.

DISCUSSION: This species was previously known only from the poorly preserved and teneral female holotype. However, the relatively large white portion of the anterior margin of the hemelytron and the completely dark-red femora are diagnostic, allowing the identification of three recently collected specimens, including the male. This species is similar to A. cordatus in possessing distinct white pigmentation and deep red coloration of the hemelytra in both the male and female, however the white patterning is more restrict- ed on the medial portion of the hemelytron in A. cordatus and the pro- and mesofemora are gold instead of burgundy as in A. macrozonata .

Ausejanus mcdonaldi (Carvalho and Gross) , new combination Figure 7 ; plate 3

Sejanus mcdonaldi Carvalho and Gross, 1982: 21 , figs. 22–24, 103 (n. sp., descr., disc., DV, MG).

Sejanus melaleucae Carvalho and Gross, 1982: 20 , fig. 120 (n. sp., descr., disc., DV). NEW SYNONYMY.

DIAGNOSIS: Body and hemelytra in male almost completely brown, whereas majority of Ausejanus species with at least a partial to complete fascia across anterior portion of hemelytra. In addition, male with reduced pigmentation of white stripe on anterior margin of cuneus; relatively thick segment 2; and smaller eyes than other congeners. Female paler in coloration, hemelytra with a golden-brown stripe along apical margin of cuneus orange rather than white, and lacking a partial or complete fascia (pl. 3).

REDESCRIPTION: Male: Macropterous, medium sized, elongate, and parallel sided. Total length 3.32–3.89, width pronotum 0.86– 1.10, maximum width across hemelytra 1.09– 1.39. COLORATION: Brown. Head dark brown. All antennal segments dark brown. All labial segments dark brown. Eyes dark red. Thorax, pronotum, scutellum dark brown. Thoracic pleuron dark brown. Procoxae gold, meso- and metacoxae dark brown basally, gold anteriorly. Pro- and mesofemora gold brown, metafemora dark brown. Tibiae gold brown, metatibiae with parallel rows of dark spicules. Tarsi dark brown. Hemelytra completely dark brown to brown, lack partial or complete fascia (pl. 3). Cuneus with yellowish-white pigmented band present as thin line along anterior margin of cuneus to thick band with width approximately J total length of cuneus, posterior of cuneus dark brown. Abdomen dark brown with segments 3–7 paler brown. STRUCTURE: Diameter of antennal segment 2 wide. Eyes relatively small and not total height of head in lateral view, width of vertex wider than width of one eye. Length segment 2 nearly as long as 1.5 times total head width. Remaining structural characteristics as in generic description. GENITALIA: As in generic description.

Female: Macropterous. Total length 2.97– 3.36, width pronotum 0.94–1.06, width at widest part of wings 1.34–1.39. STRUC- TURE: Vertex over half of total head width. Length segment 2 1.2 times total head width. COLORATION: Female generally paler than male. Antennal segment 1 gold brown, segment 2 golden brown basally then transitioning into dark brown distally for approximately halfway along segment length, segments 3 and 4 dark brown. Hemelytra primarily gold-brown in coloration, without partial or complete fascia on anterior portion. Cuneus yellowish orange along anterior margin with hemelytra for less than J total length, remaining posterior portion gold brown to darker brown.

HOSTS: Fabaceae and Myrtaceae .

DISTRIBUTION: Southeastern and southern Australia.

DISCUSSION: This species has a relatively high amount of sexual dimorphism in coloration compared to other species of Ausejanus , with the male darker in color than the female and having a thicker and completely dark brown antennal segment 2. The female type specimen of S. melaleucae is identical to the female of A. mcdonaldi , which can have a dark brown or paler brown coloration of the hemelytron in the same population. Additionally, both nominal species are found in the same geographic area. Male paratypes from New South Wales show a larger amount of white pigmentation on the anterior portion of the cuneus than a majority of the specimens recently collected in Tasmania, but the remainder of the coloration and structure is consistent across all specimens. For these reasons we are treating the two species as synonyms.

Ausejanus meridionalis (Carvalho and Gross) , new combination Figures 7 , 9D ; plate 3

Sejanus meridionalis Carvalho and Gross, 1982: 32 , fig. 106 (n. sp., descr., disc., DV).

DIAGNOSIS: Distinguishable from other members of Ausejanus by combination of relatively smaller size, ruby-red coloration of hemelytra with contrasting white-pigmented complete fascia in male (pl. 3), yellow pro- and mesofemora and ruby red metafemora, and dark brown thorax and abdomen. Coloration similar to A. albisignatus , but fascia in latter taxon primarily transparent in male rather than with white pigment in A. meridionalis .

REDESCRIPTION: Male: Macropterous, small, elongate, and parallel sided. Total length 2.72–3.19, width pronotum 0.84–0.92, maximum width across hemelytra 0.94–1.11. COLORATION: Dark brown, with hemelytra primarily burgundy to brown in color with transverse, transparent fascia on anterior portion. Head dark to medium brown. Antennal segment 1 gold to pale brown, segments 2 and 4 dark brown, with antennal segment 3 dark brown becoming pale at joint with segment 2. Labium dark brown. Eyes ruby red to dark red. Thorax, pronotum, and scutellum dark brown. Thoracic pleura dark brown. Procoxa entirely pale yellow, meso- and metacoxae dark red basally and gold apically. Pro- and mesofemora gold brown, metafemora dark. Tibiae gold with parallel rows of dark spicules. Basal tarsomeres light, distally brown. Hemelytra primarily dark red to ruby red, with white pigmented complete transverse fascia on anterior portion of hemelytron whose anterior, medial margin passes just posterior to posterior apex of scutellum (pl. 3). Cuneus white pigmented along fracture, extending approximately K to M of cuneus, remainder of cuneus dark red. Membrane pale brown, veins sometimes with subtle red pigmentation. Abdomen dark brown, with abdominal sclerites 3–7 paler. STRUCTURE: Eyes not total height of head in lateral view, width of vertex equivalent to width of one eye. Length of segment 2 nearly as long as 1.33 times total head width. Remaining structure characteristics as in generic description. GENITALIA: As in generic description.

Female: Macropterous. Total length 2.43– 2.87, width pronotum 0.86–0.95, width at widest part of wings: 0.99–1.19. STRUC- TURE: Vertex taking over half of total head width. Length segment 2 nearly 1.10 times total head width. COLORATION: Similar to male but with following exceptions: hemelytra having broader complete transparent fascia than in male (pl. 3), antennal segment 2 gold basally with darkening toward joint with third antennal segment, and cuneus with larger, white pigmented area along apical fracture margin extending approximately K to O of cuneus, remainder of cuneus dark red.

HOSTS: Primarily Fabaceae , Myrtaceae and Thymelaeaceae .

DISTRIBUTION: South Australia, New South Wales, Victoria, Western Australia, Tasmania.

DISCUSSION: Ausejanus meridionalis was described by Carvalho and Gross on the basis of a female holotype, which now is associated with male specimens. Females are fairly easy to associate with the males because both sexes have bright-red hemelytra and a white-pigmented, broad transverse fascia. Males of A. meridionalis also have white pigmentation in the transverse fascia, a characteristic that is absent in most Ausejanus species.
