Diagnosis: Proteatingis mjobergi is recognized by the following combination of characters: antennal segment I black; collum elevated, forming short hood; anterior margin of collum projecting forward; paranota areolate along entire length, areolae easily visible and well-defined; metasternal carinae truncate-obovate.

Male: Macropterous; 3.36 ± 0.13 mm (N = 10) ( Table 3 ). COLORATION. Straw-coloured to reddish brown. Head: black; spines straw-coloured; bucculae straw-coloured; eyes red in nymphs and teneral imagos, fading to black with age. Antennae: AI black, AII–AIII golden-brown, AIV golden-brown proximally, quickly darkening to dark brown or black distally. Rostrum: golden-brown with dark brown to black apex. Pronotum: disc straw-coloured to brown; calli black; collum and paranota straw-coloured to golden-brown; lateral and medial carinae straw-coloured, medial carina reddish brown to brown posteriorly, lateral carina white posteriorly. Thoracic pleura and sterna: proepisternum straw-coloured to golden-brown anteriorly, mostly black posteriorly, proepimeron straw-coloured to golden-brown, supracoxal lobes golden-brown; mesepisternum mostly black, mesepimeron and supracoxal lobes golden-brown; metepisternum black ventrally, golden-brown dorsally; peritreme of metathoracic gland straw-coloured; prosternum and mesosternum black, metasternum brown; pro-, meso-, and metasternal carinae straw-coloured. Hemelytra: discoidal area straw-coloured medially, straw-coloured to brown proximally and distally; subcostal area straw-coloured to reddish brown to brown; costal margin straw-coloured to golden-brown with brown costal veins; sutural area straw-coloured. Legs: mostly golden-brown, coxae dark brown to black; tarsi dark brown to black distally. Abdominal venter: golden-brown. VESTITURE. Head: distribution of golden-brown aciculate setae in bands from base of AI to occipital spines and from frontal spines along either side of medial spine, to back of head; frons and gena with straw-coloured aciculate setae; medial spine with straw-coloured short aciculate to hooked setae; vertex with globules of wax; bucculae with arcuate aciculate setae and ciliate punctures. Antennae: AI–AII with straw-coloured sparse, aciculate arcuate setae; AIII with straw-coloured aciculate decumbent setae, AIV with straw-coloured aciculate setae; distal ends of AII and AIII with dense ring of microtrichia. Pronotum: anterior and paranotal margins with sparse distribution of arcuate aciculate setae; medial and lateral carinae with sparse distribution of arcuate aciculate setae; disc with minute scale-like setae and numerous punctures with six to eight cilia distributed evenly around internal rim of punctures; calli often with globules of wax. Thoracic pleura and sterna: proepisternum with arcuate aciculate setae and ciliate punctures anteriorly as on pronotal disc, lacking ciliate punctures posteriorly, proepimeron and supracoxal lobes with arcuate aciculate setae and ciliate punctures; mesepisternum with arcuate aciculate setae, mesepimeron and supracoxal lobes with arcuate aciculate setae and ciliate punctures posteriorly; metepisternum with arcuate aciculate setae and ciliate punctures; pro-, meso-, and metapluron covered with small wax globules. Legs: coxae to femur glabrous, tibia with golden-brown aciculate setae, setae very short proximally, increasing in length distally; coxae with single row of arcuate aciculate setae. Hemelytra: sparse distribution of short aciculate setae on veins. Abdominal venter: aciculate setae and wax distributed throughout. STRUCTURE. Head: frontal spines slightly conical, strongly convergent to crossed, approximately one-half length of AI; medial spine stout, conical, height subequal to AI; occipital spines straight, cylindrical, exceeding length of medial spine, easily exceeding anterior edge of collum. Antennae: AI and AII short, AII one-half length of AI; AIII longer than the pronotal width across humeral angles; AIV lanceolate. Labium: moderate length, extending to anterior margin of metasternum. Pronotum: strongly convex; collum apex inflated, forming short hood, height equal to disc; anterior margin of collum projecting forward; carinae slightly elevated from disc, uniseriate, areolae very small; medial and lateral carinae equal thickness, lateral carinae divaricating anteriorly; paranota curved, following disc, upturned obliquely, uniseriate to biseriate, areolae rectangular. Thoracic sterna: pro-, meso-, and metasternal carinae elevated, uniseriate, areolae small, rectangular; prosternal and mesosternal carinae straight, parallel, metasternal carinae truncate-obovate. Hemelytra: areolae small, irregular, and nearly uniform size in discoidal and subcostal areas; sutural area areolae similar to discoidal area proximally, increasing in size to 2× distally; costal area areolae rectangular; costal area uniseriate, subcostal area biseriate, discoidal area increasing from one to six or seven areolae wide, sutural area increasing from two to seven areolae wide. Male genitalia: pygophore ( Fig. 20A, B ); parameres ( Fig. 20C–E ); dorsal plate Y-shaped ( Fig. 20F ); aedeagus with paired large endosomal lobal sclerites ( Fig. 20F–H ); endosomal spinulation present ( Fig. 20F–H ).

Female: Macropterous; 3.58 ± 0.08 mm (N = 10) ( Table 3 ). COLORATION. As in male. VESTITURE. As in male. STRUCTURE. As in male.

Plant associations: Recorded from two families and five genera. Proteaceae : Conospermum distichum , one specimen; Dryandra sessilis , two specimens; Grevillea hookeriana , one specimen; Hakea horrida , five specimens; H. obliqua , four specimens; H. pandanicarpa , 16 specimens; H. preissii , 11 specimens; H. prostrata , 21 specimens; H. trifurcata , five specimens; Hakea sp. , 19 specimens. Scrophulariaceae : Stemodia grossa , one specimen.

Distribution: Found in south-western Western Australia and near Broome, WA ( Fig. 21 ).

Remarks: This species is superficially similar to P r. burckhardti and Pr. howardi but does not overlap the distribution these species. The records reported by Drake (1961) in New South Wales, from Lane Cove and Sydney, likely represent Pr. burckhardti ; we have not seen any specimens of Pr. mjobergi south of SE Queensland, and Pr. burckhardti is well represented in the Sydney region. It can be distinguished from Pr. burckhardti by the black first antennal segment (golden-brown in Pr. burckhardti ), and from Pr. howardi by the ovorectangular areolae of the costal area (vs. reticulate in Pr. howardi ).
