Diagnosis. Inoma multispinosa is recognised by the following combination of characters: small size ( Fig. 2 View Fig ); brachypterous or macropterous ( Fig. 2 View Fig ); distinctive light cream and redbrown banding colouration on hemelytra ( Fig. 2 View Fig ); pronotum and hemelytra with elongate major setiferous tubercles, sparsely distributed, with minute, barely visible terminal seta ( Fig. 2 View Fig ); head, dorsal surface of pronotum and hemelytra, thoracic pleura and abdominal venter glabrous ( Fig. 2 View Fig ); cephalic spines elongate, occipital spines laterally curved, medial spine

Female genitalia of Inoma fuscata sp. nov. in dorsal view. 0.1 mm. CO, common oviduct; LO, lateral oviduct; Ps, pseudospermatheca.

forked ( Fig. 2 View Fig ); paranotal and costal areas uniseriate and narrow ( Fig. 2 View Fig ); paranota obliquely extended; hemelytra with large areolae in coastal area and remainder smaller ( Fig. 2 View Fig ).

Redescription of adult. Small size, macropterous (males 2.22-2.40, females 2.36-2.46) and brachypterous (males 1.94-2.17, females 1.97-2.18) morphs ( Fig. 2 View Fig ).

COLOURATION. Head: red-brown; bucculae stramineous posteriorly; cephalic spines stramineous in basal half, red-brown in distal half. Antennae: mostly orange-brown; AIV dark brown. Pronotum: disc red-brown; posterior lobe stramineous with dark brown margin; collum stramineous; paranota stramineous with red-brown margin. Thoracic pleura and sterna: pleura red-brown with paler margins; sternal carinae stramineous. Legs: mostly orange-brown; tarsi dark brown. Hemelytra: stramineous and red-brown horizontal broad banding; sutural area more orange-brown; junction of R+M and cubitus veins dark brown. Abdomen: venter uniformly very dark brown, almost black.

VESTITURE. Major setiferous tubercles present, elongate, terminal seta minute, barely visible, tubercles sparsely distributed, mostly in single rows on pronotum and hemelytra. Head, dorsum, thoracic pleura and abdominal venter without setae. Head: cephalic spines with minor setiferous tubercles present at base, terminal seta obsolete. Antennae: AIV with simple, bristle-like setae, rest glabrous. Pronotum: major setiferous tubercles in single rows, absent from ventral margin of paranota. Thoracic pleura and sterna: posteroventral margin of proepimeron with a few major setiferous tubercles; sternal carinae with minor setiferous tubercles, terminal seta obsolete. Legs: femora and tibiae with a few minor setiferous tubercles, terminal seta obsolete. Hemelytra: major setiferous tubercles in two opposing rows on posterior half of costal area, in single rows elsewhere; major setiferous tubercles on costal margin not extending to forewing apex. Abdomen: venter glabrous.

STRUCTURE. Head: spines elongate; frontal spines slightly divergent, widely separated; medial spine forked; occipital spines outwardly curved, erect. Labium: elongate, extending to metacoxae. Antennae: AIV compact, with short base. Pronotum: callar region strongly convex, tumid, in both macropters and brachypters; collum moderately enlarged; paranota uniseriate, narrow, obliquely extended, areolae of carinae small. Hemelytra: Macropters: costal area uniseriate, areolae large; subcostal area broad, as wide as discoidal area; subcostal, discoidal and sutural areas with mostly small areolae; hypocosta broad, as wide as costal area. Brachypters: reduced sutural and costal areas; sutural area greatly reduced; all other characters as for macropters. Male genitalia: parameres with slightly angular sensory lobe, sensory lobe with short setae, inner margin and outer margin of apophysis with short setae, dorsal surface of paramere smooth, without minute setae ( Fig. 10 View Fig a-b); distal U-shaped endosomal sclerite with deep and squared cleft, long basal branches, and a sinuate distal margin ( Fig. 10c View Fig ); with paired basal endosomal sclerites, very small, sub-triangular in shape ( Fig. 10m View Fig ).

MEASUREMENTS. Ranges of 9 JJ and 2 ♀♀ macropters and 7 JJ and 10 ♀♀ brachypters given in Table 2.

Differential diagnosis. Inoma multispinosa is distinguished from all other Inoma species by the following characters: 1) lack of woolly or scale-like setae; 2) distinctive cream and reddish brown colour banding on hemelytra; 3) sparsely distributed, elongate setiferous tubercles with minute terminal seta; and, 4) deeply bifurcate, medial cephalic spine.

Biology. Inoma multispinosa was collected on the pea species, Dillwynia retorta (Fabaceae) , in the Australian Capital Territory. No hosts were recorded for specimens collected in Queensland. The host plant for this species is found in heathlands and dry sclerophyll forests, and is generally limited to the east of the Great Dividing Range, from south-east Queensland south to Victoria (CHAH 2008; Australia’s Virtual Herbarium).

Distribution. Inoma multispinosa is known from temperate to subtropical areas of the eastern seaboard of Australia, ranging from south-east Queensland to Canberra in the Australian Capital Territory ( Fig. 13a). It is distinguished biogeographically from all other species of Inoma , which are known from arid Australia to the drier climes of coastal south-west Western Australia.
