Diagnosis: Proteatingis xouthos can be recognized by the following combination of characters: anterior margin of collum curved medially, projecting forward; anterior portion of costal area uniseriate; paranota areolate along entire length, areolae easily visible and well-defined; metasternal carinae curved, obovate, width between metasternal carinae greater than width between mesosternal carinae; areolae of lateral carinae large, easily seen.
Male: Macropterous; 3.19 ± 0.08 mm (N = 10) (Table 3). COLORATION. Straw-coloured. Head: dark brown; spines straw-coloured; bucculae straw-coloured; eyes red. Antennae: AI–AIII golden-brown, AIV brown. Rostrum: golden-brown with dark brown to black band distally on first segment to proximally on second segment, dark brown to black apex. Pronotum: disc straw-coloured; calli dark brown; collum and paranota straw-coloured; lateral carinae straw-coloured, medial carina golden-brown. Thoracic pleura and sterna: proepisternum straw-coloured anteriorly, mostly brown posteriorly, proepimeron and supracoxal lobes straw-coloured; mesepisternum mostly dark brown to black, mesepimeron and supracoxal lobes golden-brown to straw-coloured; metepisternum brown anteriorly, straw-coloured posteriorly; peritreme of metathoracic gland straw-coloured; prosternum brown, mesosternum dark brown, metasternum golden-brown to brown; pro-, meso-, and metasternal carinae straw-coloured. Hemelytra: straw-coloured; costal area veins brown; R + M vein with dark brown blotch distally; cubitus vein with two dark brown blotches. Legs: mostly straw-coloured, coxae dark brown; tarsi straw-coloured to brown. Abdominal venter: brown. VESTITURE. Head: distribution of straw-coloured 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, ciliate punctures, and globules of wax. 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 arcuate aciculate setae, continuing onto medial and lateral carinae; disc with minute scale-like setae, numerous punctures with six to eight cilia distributed evenly around internal rim of punctures; calli with short straw-coloured cilia, 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: coxa to femur glabrous, tibia and tarsus with straw-coloured aciculate setae. Hemelytra: glabrous, rarely with short aciculate setae on veins. Abdominal venter: aciculate setae and wax distributed throughout. STRUCTURE. Head: frontal spines slightly conical, convergent, approximately one-third length of AI; medial spine straight, conical apically, height approximately equal to AI, approximately 5× longer than wide; occipital spines straight, cylindrical, approximately equal to 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 weakly clavate. Labium: moderate length, extending to posterior margin of mesosternum. Pronotum: strongly convex; collum apex produced, height subequal to disc; carinae greatly elevated from disc, uniseriate, areolae rectangular; medial and lateral carinae equal thickness, lateral carinae mostly parallel, divaricating slightly anteriorly; paranota curved, following disc, upturned obliquely, uniseriate, areolae rectangular. Thoracic sterna: prosternal and mesosternal carinae minimally elevated, areolae barely visible on mesosternal carina; metasternal carinae slightly elevated, uniseriate, areolae rectangular; prosternal and mesosternal carinae straight, parallel, metasternal carinae slightly obovate. Hemelytra: areolae small, irregular, of varying size in discoidal and subcostal areas; sutural area areolae similar to discoidal area proximally, increasing in size to 3× distally; costal area areolae large, rectangular; costal area uniseriate, subcostal area biseriate, discoidal area increasing from one to five or six areolae wide, sutural area increasing from one to nine areolae wide. Male genitalia: pygophore (Fig. 22A, B); parameres (Fig. 22C–E); dorsal plate Y-shaped (Fig. 22F); aedeagus with paired large endosomal lobal sclerites (Fig. 22F–H); endosomal spinulation variable in size, with some spinules enlarged (Fig. 22F–H).
Female: Macropterous; 3.23 ± 0.11 mm (N = 10) (Table 3). COLORATION. As in male. VESTITURE. As in male. STRUCTURE. As in male.
Plant associations: Recorded from three families and five genera. Anacardiaceae: Mangifera indica, one specimen. Fabaceae: Crotalaria aridicola, one specimen; Jacksonia thesioides, two specimens. Proteaceae: Grevillea agrifolia, 14 specimens; G. decora, one specimen; G. parallela, two specimens; G. pteridifolia, 13 specimens; G. teretifolia, eight specimens; Grevillea sp., three specimens; Hakea arborescens, 16 specimens.
Distribution: Occurs across northern Australia from the Kimberley region in Western Australia to the Wet Tropics in Far North Queensland; isolated records in White Mountains National Park and Glasshouse Mountains National Park, Queensland (Fig. 21).
Remarks: Proteatingis xouthos is similar to P r. astibosetes and Pr. burckhardti. It can be distinguished from these species by the large areolae on the paranota, costal area, and medial carina, as well as the broad paranota. The known range of Pr. xouthos is larger than any other species of Proteatingis. It occurs in a wide variety of habitats over its extensive distribution.
