PARATYPES: AUSTRALIA: SOUTH AUSTRALIA: 17.6 km S of Innamincka, 27.88068°S 140.6712°E, 130 m, 06 Nov 1998, Schuh, Cassis, Silveira, ex. Teucrium racemosum R. Br. ( Lamiaceae ; det.NSW Herbarium NSW427991), 3 ♀♀ ( AMNH _PBI 00013137- AMNH _PBI 00013138, AMNH _PBI 00013659) ( AM).
Diagnosis. This species is recognised by the following combination of characters: small size ( Fig. 1 View Fig ); ovoid body ( Fig. 1 View Fig ); generally light-brown to stramineous colouration dorsally and dark brown venter ( Fig. 1 View Fig ); body densely covered with short, curled, silvery, woolly setae ( Figs. 1 View Fig , 6 View Fig a-f); minor setiferous tubercles densely distributed ( Figs. 6 View Fig a-e), terminal seta short and recurved, longer than tuberculate base ( Figs. 6 View Fig a-e); frontal cephalic spines elongate, medial and occipital spines stout ( Fig. 6a View Fig ); paranotal and costal areas uniseriate ( Figs. 1 View Fig , 6 View Fig d-e); hemelytra of brachypters with large areolae in costal area, small in remainder ( Figs. 1 View Fig , 6e View Fig ).
Description of adult. Small species, only brachypterous morph known (male 1.95, females 1.93-2.17) ( Fig. 1 View Fig ).
COLOURATION. Head: medium brown, spines and bucculae stramineous. Labium: mostly dark brown. Antennae: mostly orange-brown, AIV dark brown. Pronotum: disc medium brown, remainder stramineous, light brown spot on apex of collum and middle of median carina. Thoracic pleura: red-brown with paler margins. Thoracic sterna: dark brown; sternal carinae stramineous. Legs: mostly orange-brown, slightly darker at base of femora; tarsi dark brown. Hemelytra: mostly patchy stramineous/cream and yellow-brown; darker orange brown patches medially on R+M vein, at junction of R+M and cubitus veins and on some horizontal areole margins in costal area. Abdomen: venter dark red-brown.
VESTITURE. Woolly setae present on head, dorsum and thoracic pleura, moderately dense distribution, setae short, curly, silvery, fine ( Fig. 6 View Fig a-e). Minor setiferous tubercles on pronotum and hemelytra with minute tuberculate base and short recurved seta, slightly longer than base; densely distributed ( Fig. 6 View Fig a-e). Head: minor setiferous tubercles present, covering entire cephalic spines ( Fig. 6a View Fig ). Antennae: minor setiferous tubercles present on AIII, terminal seta elongate with tapered apex. Pronotum: minor setiferous tubercles densely distributed, not in rows as such ( Fig. 6d View Fig ). Thoracic pleura and sterna: posteroventral margin of proepimeron with a few minor setiferous tubercles; sternal carinae with two rows of recurved scale-like setae. Legs: femora and tibiae with a dense distribution of short, weakly clavate, pale, scale- like setae. Hemelytra: minor setiferous tubercles as on pronotum and extending to forewing apex ( Fig. 6e View Fig ). Abdomen: venter with moderately dense distribution of short, clavate, silvery, scale-like setae ( Fig. 6f View Fig ).
STRUCTURE. Head ( Fig. 6 View Fig a-d): frontal spines moderately elongate, converging slightly ( Fig. 6a View Fig ); medial spine stout, straight ( Fig. 6a View Fig ); occipital spines stout, parallel, directed forwards, straight ( Fig. 6a View Fig ). Labium: short, not extending past mesosternum. Antennae: AIV without elongate base. Pronotum: disc flat (brachypters); collum slightly enlarged, apex slightly rounded; paranota uniseriate, narrow, obliquely extended; carinae, areolae large ( Fig. 6d View Fig ). Hemelytra: brachypters ( Fig. 6e View Fig ); costal area uniseriate, areolae large ( Fig. 6e View Fig ); areolae small over remainder of hemelytra ( Fig. 6e View Fig ); hypocostal area wide, same width as costal area. Male genitalia: parameres with rounded sensory lobe, sensory lobe with elongate setae, inner margin of parameres with short setae, dorsal surface of parameres with broad distribution of minute setae; distal U-shaped endosomal sclerite moderately sclerotised, with shallow and rounded cleft, long basal branches, and a straight distal margin; paired basal endosomal sclerites present, semi-circular with small raised surface bumps ( Fig. 10l View Fig ). Female genitalia: subgenital plate triangular ( Fig. 6f View Fig ).
MEASUREMENTS. Ranges of 1 J and 3 ♀♀ given in Table 1.
Differential diagnosis. Inoma innamincka sp. nov. is similar to I. arrernte sp. nov., but differs by the following character states: 1) slightly larger; 2) shorter and slightly less dense distribution of woolly setae; 3) very short curved terminal setae on minor setiferous tubercles; 4) darker brown abdomen, with short, clavate scale-like setae; and, 5) shorter labium, just reaching mesocoxae. This species is the only Inoma speices that is currently known from brachypterous specimens alone. Like I. arrernte sp. nov., it can be distinguished from I. silveirae sp. nov. by having minor setiferous tubercles, a slightly more elevated collum, and more stramineous or cream colouration.
Etymology. This species is named after the town of Innamincka, near the type locality. Noun in apposition.
Biology. Inoma innamincka sp. nov. is known only from the labiate species, Teucrium racemosum (Lamiaceae) .
Distribution. This species is known only from the type locality, just south of Innamincka, South Australia (see Fig. 13a).
