Additional material examined. AUSTRALIA: NORTHERN TERRITORY: 25.3 km NW of Bond Springs on Tanami Rd, 23.51668°S 133.6212°E, 746 m, 21 Oct 2001, Cassis, Schuh, Schwartz, Silveira, Wall, ex.

Diagnosis. This species is recognised by the following combination of characters: medium size; mostly dark brown, with variegated colouration pattern ( Fig. 1 View Fig ); head, pronotum and venter covered with moderately dense distribution of short, adpressed, thickened, scale-like setae ( Fig. 1 View Fig ), absent from hemelytra; pronotum and hemelytra with major setiferous tubercles, with tuberculate base longer than seta ( Fig. 1 View Fig ); cephalic spines moderately elongate ( Fig. 1 View Fig ); occipital spines laterally arcuate ( Fig. 1 View Fig ); medial spine apically bifurcate ( Fig. 1 View Fig ); paranota biseriate, obliquely upturned ( Fig. 1 View Fig ); longitudinal carinae narrow ( Fig. 1 View Fig ); costal area uniseriate ( Fig. 1 View Fig ); hemelytra with large areolae in costal and sutural areas, small areolae in subcostal and discoidal areas ( Fig. 1 View Fig ).

Description of adult. Relatively small size, macropterous form (males 2.34-2.35, females 2.40-2.53) ( Fig. 1 View Fig ).

COLOURATION. Body mostly dark brown with paler markings ( Fig. 1 View Fig ). Head: dark brown to black; spines orange-brown; basal half of bucculae dark brown, rest orange-brown. Labium: dark brown.Antennae: AI and AII orange-brown; AIII-AIV missing. Pronotum: dark brown to black, posterolateral margins paler; collum orange-brown; paranota orange-brown and stramineous; carinae stramineous, median carina with a dark brown marking medially. Thoracic pleura and sterna: dark brown; sternal carinae lighter, orange-brown. Legs: mostly orange-brown; tarsi dark brown. Hemelytra: mottled colouration, stramineous, orange-brown to dark brown; sutural area dark brown. Abdomen: venter dark brown.

VESTITURE. Body with moderately dense distribution of short, lanceolate, adpressed, silvery, scale-like setae ( Fig. 1 View Fig ); major setiferous tubercles present on pronotum and hemelytra, elongate base, seta shorter than tuberculate base. Head: minor setiferous tubercles present at base of cephalic spines. Antennae: AIII with minor setiferous tubercles, terminal seta with rounded apex. Pronotum: moderately dense distribution of scale-like setae, sparser posteriorly; major setiferous tubercles mostly in single rows, in two opposing rows on posterior half of paranotal margin. Thoracic pleura and sterna: scale-like setae dense, more sparse on supracoxal lobes and sterna; posteroventral margin of proepimeron with a few major setiferous tubercles, seta equal to tubercluate base; sternal carinae with single row of recurved, scale-like setae. Legs: femora and tibiae with rows of minor setiferous tubercles, terminal seta elongate, pale, erect, bristle-like. Hemelytra: without setae; major setiferous tubercles in two opposing rows along costal margin, extending to forewing apex. Abdomen: venter with moderately dense distribution of short, silvery, adpressed, scale-like setae.

STRUCTURE. Head: spines elongate; frontal spines diverging slightly; medial spine shorter, apex forked; occipital spines curved outward. Labium: short, not extending past mesosternum. Pronotum: disc convex, tumid; collum slightly enlarged; paranota biseriate, obliquely extended, inner row of areolae very small. Hemelytra: costal area uniseriate, areolae large; subcostal and discoidal areas with small areolae; sutural area with large areolae; hypocosta very narrow. Male genitalia: not examined.

MEASUREMENTS. Ranges of 2 JJ and 2 ♀♀ given in Table 1.

Description of fifth instar larva ( Fig. 3 View Fig ). COLOURATION. Dorsum orange-brown, with darker red-brown areas at base and apices of hemelytral lobes, abdominal venter, AIV, and tarsi.

VESTITURE AND STRUCTURE. Dorsum with moderate distribution of short, spinelike, pale cuticular outgrowths; pronotum with two pairs of elongate, medial processes; mesonotum, metanotum and abdominal tergite I with paired medial processes, elongate on mesonotum, short on metanotum and abdominal tergite I; abdominal tergites II, V, VI and VIII with single, elongate, medial process; lateral margins of pronotum and hemelytral lobes, and posterolateral corners of abdominal tergites with elongate processes projected laterally; processes covered with minor setiferous tubercles, terminal seta short, spine-like; medial cephalic spine bifurcate.

Differential diagnosis. This species can be distinguished by its short, adpressed, scale-like setae and the absence of any setae on the hemelytra. This species is similar to I. fuscata sp. nov. but differs by the setal characters above and also by being slightly smaller, in addition to having a bifurcate medial cephalic spine and a uniseriate costal area.

Etymology. Named for the short scale-like setae on the head, pronotum and venter of this species. Noun in apposition.

Biology. Inoma breviseta sp. nov. has been collected on Eremophila gilesii (Myoporaceae) in the Northern Territory ( Fig. 12d View Fig ), and an unidentified Eremophila species in South Australia.

Distribution. Inoma breviseta sp. nov. is known from three localities in central Australia ( Fig. 13b), two in the Alice Springs region, and a disjunct location in the Flinders Ranges of South Australia. It is known from low to mid elevations (ca. 175-800 m). This species has been collected at the same locality as Inoma fuscata sp. nov. and I. silveirae sp. nov. ( Fig. 12c View Fig ).
