Type material. Holotype male. 1. “ 16058.386 S 145026.690 E ( GPS) Qld. Harte Close, Mareeba 4 January 2025 DCF Rentz stop 1”, 2. “ ANIC database #9-006318” . Holotype in Australian National Insect Collection, Canberra.

Paratypes. Same locality and date, 31 males, 6 females. Same locality 15 March 2025, 3 males, 1 female. 16047 ’28“S. 145040 ’16“E (phone) QLD. Kewarra Beach, nr Reefsedge Park., 5 July 2025 DCF Rentz Stop 9, 1 female. All in ANIC .

Type locality. ( In litt.) from T. Utzinger the type locality is described “as open dry sclerophyll forest bordering on riparian vegetation. Dominant species Eucalyptus tesselaris , Eucalyptus alba , Callitris macleayana , Pandanus sp , Melaleuca leucadendra . I suspect my habit of mulching a considerable amount of cut vegetation back into the landscape very likely contributes to hosting a wide range of species.”

Differential diagnosis. Differs from all other known Johnrehnia species in the following:

Antenna with scape and pedicel straw brown, flagellum black, without annuli ( Fig. 4A View FIG ); frons spotted, often with dark overcast ( Fig. 4J View FIG ); occiput dark brown, with a few indistinct light brown stripes ( Fig. 4A View FIG ); pronotum with distinctive dark brown markings, central region light brown and with 2 tiny spots near posterior margin ( Fig. 4A View FIG ); tegmina and wing venation ( Fig. 4H View FIG ), dorsal surface of each tegmen with an elongate, converging curved dark brown stripe ( Figs 4A, H View FIG ); legs uniformly light brown, base of each spine dark brown, right fore femur ( Fig. 4G View FIG ). Ninth abdominal tergite with a prominent triangular projection, tenth tergite with a pair of slender, decurved projections, the apex of each is minutely incised ( Figs 4B, C View FIG ); concealed genitalia with slender clasper on each side ( Fig. 4C View FIG ); median phallomere slender and sharp ( Fig. 4D View FIG ), genital hook apically incised ( Fig. 4D View FIG ); subgenital plate with right style spiniform ( Fig. 4F View FIG ), left style short and straight; cercus straw with black annuli ( Fig. 4C View FIG ). Female with tenth tergite feeble incised, subgenital plate apically subtruncate ( Fig. 4I View FIG ).

Description. Male/female. Overall colour light brown. Tegmina with elongate convergent dark brown, thin stripes ( Fig. 4H View FIG ). Head with frons spotted, with dark overcast ( Fig. 4J View FIG ); scape and pedicel of antenna straw brown, flagellum black, not annulate ( Figs 4A, H View FIG ); occiput dark brown to black with indistinct lighter markings ( Fig. 4J View FIG ). Thorax. Pronotum with distinct colour pattern and spots near posterior margin ( Fig. 4A View FIG ). Tegmina light brown with veins darker brown, with distinct elongate curved stripe on each tegmen ( Fig. 4H View FIG ). Male abdomen mottled light and dark brown; tenth tergite dark brown in the middle and with a pair of slender, decurved prongs, each one minutely incised apically ( Fig. 4B View FIG ); subgenital plate dark brown in central portion, laterally lighter brown, right style swollen basally, apically hooked ( Figs 4E, F View FIG ), left style normal, unmodified. Concealed genitalia with hook notched apically ( Fig. 4D View FIG ); median phallomere elongate, slightly upcurved ( Fig. 4D View FIG ). Female with tenth tergite feebly incised; subgenital plate apically subtruncate, otherwise unmodified ( Fig. 4I View FIG ).

Remarks. The female collected on 15 March 2025 produced an ootheca ( Fig. 5A View FIG ) which was deposited on 23 March 2025. The ootheca was found loosely in some cereal food on the bottom of the jar in which it was housed. This suggests that the ootheca of this species are placed in mulch or leaf litter. The single ootheca measured 4.2 mm in length ( Fig. 5B View FIG ). Nymphs emerged 10 May 2025 ( Fig. 5C View FIG ). The newly emerged nymphs are white with black eyes ( Figs 5D, E View FIG ) and measure 1.4 mm. After 24 hour the nymphs acquired a distinctive colour pattern ( Fig. 5F View FIG ). Oddly, the nymphs could not be raised to adulthood.

Etymology. Named with reference to the spots on the frons and the 2 spots on the dorsal surface of the pronotum.
