Diagnosis. This species is recognised by the following combination of characters: medium size ( Fig. 2 View Fig ); minor sexual dimorphism, male with a very dark pronotal callar region and hemelytra markings, larger eyes and hemelytra, female paler, hemelytra slightly smaller in sutural area and less rounded apically, eyes very small ( Fig. 2 View Fig ); body covered with elongate, silvery setae ( Fig. 9 View Fig a-e); setae on abdominal venter elongate and semi-erect ( Fig. 9h View Fig ); pronotum ( Fig. 9d View Fig ) and hemelytra ( Fig. 9e View Fig ) with moderately elongate major setiferous tubercles, terminal seta no longer than tuberculate base on pronotum and costal margins, much longer than base on hemelytral veins ( Fig. 9e View Fig ), with greatly elongate terminal seta anteriorly on paranota ( Fig. 9a View Fig ); cephalic spines elongate, occipital spines outcurved ( Fig. 9a View Fig ); paranota ( Fig. 9d View Fig ) and costal areas ( Fig. 9e View Fig ) biseriate, paranota obliquely extended; hemelytra with large areolae in costal area, rest generally small ( Fig. 9e View Fig ).
Description of adult. Moderate size, macropterous form (males 2.59-3.27, females 2.74- 3.00) ( Fig. 2 View Fig ).
COLOURATION. Head: dark brown, almost black; spines stramineous; bucculae mostly orange brown, margins paler. Labium: mostly dark brown. Antennae: AI and AII red/orange brown; AIII yellow-brown; AIV dark brown, almost black. Pronotum: callar region dark brown, almost black, lighter posteriorly; posterior lobe stramineous; collum, paranota and carinae stramineous with light to medium brown patches along margins. Thoracic pleura: mostly dark brown, supracoxal lobes lighter red (medium)-brown. Thoracic sterna: dark brown, almost black, sterna carinae stramineous. Legs: mostly yellow/orange-brown, basal two-thirds of femora sometimes darker red-brown; tarsi dark brown. Hemelytra: patchwork; stramineous, yellowy and orange-brown and dark-brown markings.Abdomen: venter uniformly dark brown. Female generally lighter; pronotal callar region red-brown; legs orange-brown; hemelytra more uniform yellow and orange brown with red-brown patches.
VESTITURE. Woolly setae present on head, dorsum and thoracic pleura, moderately dense distribution, elongate, curly, silvery and slightly thickened. Major setiferous tubercles on pronotum and hemelytra, moderately elongate, terminal seta mostly short, no longer than tuberculate base ( Fig. 9 View Fig a-e). Head: minor setiferous tubercles covering cephalic spines ( Fig. 9a View Fig ). Antennae: minor setiferous tubercles present on AIII, terminal seta elongate with tapered apex ( Fig 9a View Fig ). Pronotum: major setiferous tubercles in two opposing rows on collum, paranota and carinae ( Fig. 9d View Fig ); first anterior tubercle on paranota with greatly elongate straight terminal seta ( Fig. 9a View Fig ). Thoracic pleura and sterna: woolly setae straighter on pleura than pronotum; sternal carinae with two-rows of hair-like setae. Legs: femora and tibiae with minor setiferous tubercles, terminal seta elongate, erect, pale and bristle-like. Hemelytra: major setiferous tubercles in two opposing rows along costal margin, extending to forewing apex; major setiferous tubercles on hemelytra veins in single row, terminal seta greatly elongate, straight ( Fig. 9e View Fig ). Abdomen: venter with dense distribution of elongate, erect, pale, straight, hair-like setae ( Fig. 9h View Fig ).
STRUCTURE. Head ( Figs. 9 View Fig a-d): cephalic spines elongate ( Fig. 9a View Fig ); frontal spines straight ( Fig. 9 View Fig ia); medial spine straight ( Fig. 9a View Fig ); occipital spines strongly curved outwards ( Fig. 9a View Fig ). Labium: elongate, extending to metacoxae. Antennae: AIV compact, with short base. Pronotum: callar region convex, slightly tumid; collum slightly enlarged; paranota biseriate, obliquely extended; carinae areolae small ( Fig. 9d View Fig ). Hemelytra: costal area biseriate; areolae large; subcostal, discoidal and most of sutural area with small areolae; hypocosta very narrow ( Fig. 9e View Fig ); female hemelytra slightly smaller with smaller/reduced sutural area. Legs: pretarsus ( Fig. 9f View Fig ). Male genitalia: pygophore ( Fig. 9g View Fig ); parameres with rounded sensory lobe, sensory lobe with a few elongate setae, inner margin with short setae, dorsal surface of parameres with broad distribution of minute setae; distal U-shaped endosomal sclerite with shallow and rounded cleft, long basal branches, and a straight distal margin; without paired basal endosomal sclerites. Female genitalia: sub-triangular subgenital plate, moderate size ( Fig. 9h View Fig ).
MEASUREMENTS. Ranges of 5 JJ and 9 ♀♀ given in Table 2.
Differential diagnosis. Inoma stysi sp. nov. is similar to I. solusa sp. nov., but is distinguished from it by the following character states: 1) elongate major setiferous tubercles on pronotum and hemelytra, more so on forewings; and, 3) moderately dense distribution of woolly setae on the hemelytra (cf. to almost glabrous hemelytra in I. solusa sp. nov.).
Etymology. This species is named in honour of Professor Pavel Štys, in recognition of his contributions to heteropterology.
Biology. Inoma stysi sp. nov. has been collected on Eremophila forrestii (Myoporaceae) , from a number of localities ( Fig. 12g View Fig ) in Western Australia and Eremophila macdonnellii in the Northern Territory. No host plant was recorded for the lone Pilbara specimen.
Distribution. Inoma stysi sp. nov. is known from three localities in south-central Western Australia and a single record from farther north in the Pilbara region ( Fig. 13b). This species is also known from central Australia in the south of the Northern Territory.
