Material examined. Australia: 2 males, 1 female, Queensland, Cape Tribulation , 16°07'S, 145°26'E, tropical rainforest, 10–30.III.2000, S. Storozhenko ( ZIN) .

Description. Female. Body robust. Antennae 15-segmented, 1.5 times as long as fore femur; middle segments (seventh–ninth) 5–6 times as long as wide. Antennal grooves situated almost between lower margins of eyes, i.e. upper margins of antennal grooves located at same level as lower margins of eyes. Fastigium of vertex 1.5 times as wide as one compound eye seen from above; anterior margin of vertex straight, slightly surpassing frontal line of eyes; lateral margins of vertex parallel; median carina of fastigium short; transverse carinae only traced by few tubercles; supraocular lobes and fossulae absent. Lateral ocelli situated between middles of eyes. Frontal ridge, in lateral view, broadly rounded with two shallow concavities, one above lateral ocelli and another below antennal grooves. Width of frontal ridge near base of antennae 1.8 times as great as width of first antennal segment. Pronotum slightly surpassing 1/3 of hind femora. Lateral carinae of pronotum well defined, parallel; prozona as long as wide. Humero-apical carinae sinuate; interhumeral carinae absent. Infrascapular area long and narrow. Fore and mid femora with upper carinae almost straight; lower carinae weakly sinuate. Fore femur 3.3 times and mid femur 3.5 times as long as wide. Hind femur stout, 2.5 times as long as wide; upper and lower carinae gentle serrated; genicular tooth as long as antegenicular tooth. Upper side of hind tibia with 7–8 outer and 5–6 inner spines. First tarsal segment of hind legs 2.7 times as long as third one (without claws). Subgenital plate elongated, 1.3 times as long as wide, with deep median furrow bordered with ridges; apex of plate distinctly excised. Cerci conical, narrowing apically, with rounded apices, 2.3 times as long as wide near cercal base. Upper valve of ovipositor 4.5 times as long as its maximum width; lower valve of ovipositor 5.7 times as long as its maximum width.

Body blackish brown. Head blackish. Eyes dark brown. Antennae brown. Dorsal side of pronotum blackish with indistinct brown marks. Lateral lobes of pronotum blackish brown with lower parts brown; infrascapular area blackish. Fore and mid femora blackish with brown marks. Fore and mid tibiae brown, with two black rings. First segment of fore and mid tarsi dark brown, with second segment light brown but having black apex, and with brown claws. Outer side of hind femur above lower outer keel brown with blackish marks, but below lower outer keel, this femur black. Hind tibiae blackish with brown rings situated at base and near middle; apex of tibia light brown. Hind tarsi light brown. Abdomen blackish with light brown lateral and medial stripes, but sternites and subgenital plate completely blackish, and cerci blackish brown. Ovipositor brown.

Male (nov.). Body similar to female but smaller. Antennae 14-segmented, 1.6–1.7 times as long as fore femora; mid segments of antennae 5.5–6.3 times as long as wide. Vertex as in female; fastigium of vertex 1.5–1.6 times as wide as one compound eye seen from above. Width of frontal ridge near base of antennae 1.8 times as great as width of first antennal segment ( Fig. 14 ). Pronotum as in female, but prozona 1.1 times as long as wide; posterior pronotal process almost reaching epiproct. Femora as in female; fore femur 3.3–3.4 times, mid femur 3.3–3.6 times and hind femur 2.4–2.5 times as long as wide. Dorsal side of hind tibia with 7–8 outer and six inner spines. First tarsal segment of hind leg 2.5–2.8 times as long as third one (without claws). Epiproct narrowly triangular, 1.8 times as long as wide near its base, with pointed apex. Subgenital plate, in lateral view, short with pointed apex ( Fig. 15 ); apex of this plate bifurcated in ventral view. Cercus 2.1– 2.3 times as long as wide, widened near base and narrowed in apical part.

Colouration as in female, but cerci light brown.

Length (in mm). Body: male 8.3–8.5, female 8.8; pronotum: male 5.3–5.4, female 6.3; antenna: male 3.0–3.2, female 2.9; fore femur: male 1.8–1.9, female 2.0; mid femur: male 2.0, female 2.1; hind femur: male 5.4–5.5, female 5.9; ovipositor 1.3.

Distribution. Australia (Queensland).

Remarks. This species was briefly described from the single female without hind legs. The photos of this specimen prepared by J. Tumbrinck are available in the Orthoptera Species File ( Cigliano et al., 2018). It allows me to correctly identify this species. The previously unknown male is described above.
