Types. Holotype, ♂, AUSTRALIA, SA: 45km E of Kimba , 30.ix.1977 (F.H.U. Baker) ( ASCU ASCTHE026378 View Materials ) . Paratypes, SA: 1 ♀, 8 mi. WNW of Nunjikompita , 1.x.1968 (Key, Upton, Balderson) ( ANIC) ; 1 ♀, Brookfield Con. Pk, 34.19S, 139.32E, Site 7, under mallee bark, 3.–12.ix.1991 (Lawrence, Weir, Dressler) ( ANIC) GoogleMaps .

Etymology. Named after the type locality, Kimba.

Colour. Head and pronotum dark brown to black with highly contrasting yellow or orange carinae. Mesonotum dark brown to black with orange carinae. Forewings whitish, veins light brown to whitish, concolorous with cells; tubercles dark brown in distinct contrast with light coloured veins. Pterostigma, crossveins and apical parts of veins slightly darker. Legs brown, dark near base, light near apex, body mid to dark brown.

Morphology. Body length: ♂ 5.6 mm; ♀ 6.2–6.7 mm.

Head: Vertex 2.3 x wider than long; median carina of vertex covering entire length of basal compartment of vertex; absent in apical compartment. Frons 1.4 x longer than wide; position of maximum width distinctly dorsad of frontoclypeal suture; lateral carinae of frons in facial view convex, rectilinear apically. Frontoclypeal suture strongly semicircular, bent upwards, median part just or just not reaching lower margin of antennal scape. Postclypeus with median carina well developed, evanescent near frontoclypeal suture. Anteclypeus with median carina moderately developed. Rostrum reaching hind coxae.

Thorax: Hind margin of pronotum rectangular. Mesonotum with median carina moderately developed, evanescent near posterior end; lateral carinae moderately to well developed. Forewing 3.6 x longer than wide; concavity at costal border absent; costal margin with about 10 tubercles; fork of ScP+RA and RP about same level as fork CuA1 and CuA2; tubercles of forewing dark, distinctly contrasted to paler coloured veins; ScP+RA apically bifid; RP trifid; additional subapical cell between branches of MP1 and MP2 absent; MP1+2 trifid; MP3+4 bifid; 11 apical cells; 6 subapical cells. Hind leg: tibia with 6 apical spines; 1 st tarsomere with 9–10 apical teeth and 4–5 platellae; 2 nd tarsomere with 9–10 apical teeth and 7–8 platellae.

Male genitalia: Anal tube as in Figs 26 View FIGURE 26 D–E. Pygofer and genital styles as in Figs 26 View FIGURE 26 F–G. Aedeagus as in Figs 26 View FIGURE 26 A–C. Phallotheca near base with a bifurcate ventral process at the end of a very large ventral ridge; phallotheca left lateral with a long spine (a), almost straight in ventral view, slightly curved in lateral view; right lateral with a short spine (b), almost straight in ventral view, strongly curved in lateral view; phallotheca forming a well sclerotised ridge right lateral.

Diagnosis. This species is the only species within Chidaea in which the left lateral spine (a) is distinctly longer (almost twice the length) than the other spine on the phallotheca. In all other species the spines are either about the same length or spine (b) is longer. Distribution: SA.
