Holotype male. Labels. 1. “ Townsville, Queensland”. 2. “ ANIC 14-008483”. Holotype ( Fig. 3A, B View FIGURE 3, A – D ) deposited in Australian National Insect Collection, Canberra in agreement with Academy of Natural Sciences of Drexel University.
Type locality. There is no further information on the collection of the type. It seems unlikely that the specimen was collected in Townsville. It is more probable that it came from the mountainous region near Townsville, perhaps around Paluma. The specimens collected from Kuranda were from a simple to complex mesophyll to notophyll vine forest on moderately to poorly drained metamorphics (Regional Ecosystem 7.11.1 EPA, 2007).
Differential diagnosis. The ventral margin of the pronotum is distinctive in both sexes in its armature and colour ( Fig. 3C View FIGURE 3, A – D , 4A View FIGURE 4, A – L ). This species is most closely related to C. angularis sp nov. based on this character and feature of the genitalia. The male cercus ( Fig. 3D View FIGURE 3, A – D ) is unique in the lack of development of the external tooth and the reduced production of the male phallus (titillator). The female supra-anal plate is very prominent, about twice as long as broad and apically narrowed and then sub-truncate.
General. A moderately large species with orange spots on the tegmina and a narrow yellow band on the anterior margin of each tegmen.
Male. Head. Frons not appreciably concave when viewed laterally, surface smooth, genae not swollen. Fastigium of vertex ( Fig. 4B, D View FIGURE 4, A – L ) with a distinctive sulcus, narrowed at each end and with a tubercle on each side at base. Antennal scape well produced on internal margin, anterior margin of dorsal surface bearing a minute tooth.
Thorax. Pronotum with anterior margin with 3 minute tubercles on each side and a single tubercle on each side caudal to those on the cephalic margin ( Fig. 3C View FIGURE 3, A – D , 4C View FIGURE 4, A – L ); lateral margin with a pair of teeth on each segment, the second tooth on the metanotum about half the size of the other; surface of disk cut by 2 undulating sulci continuous onto lateral lobe; lateral lobe with a single minute tubercle ( Fig. 4C View FIGURE 4, A – L ) in the middle of the pro- and metanotum; ventral margin of lateral lobe with a continuous row of small tubercles, those in the region of the black stripe larger than the others. Thoracic auditory spiracle minutely circular. Sternum with prosternal processes not appreciably thickened, close-set and not abruptly narrowing apically. Mesosternum with anterior margin of plates not deeply divided, with teeth on each side and of uniform size. Metasternum with few or no tubercles.
Legs. Fore coxa with a very elongate spine. Fore tibia with 4 spines on each side of ventral surface and an apical spine on each side. Middle tibia swollen in proximal one-third and armed with 4 spines in apical one-third on anterior margin and an apical spine, posterior margin with 3 spines and an apical spine. Hind tibia with a number of tooth-like spines on each margin of dorsal surface and no apical spine; ventral surface with 5–6 spines on each angle and a single apical spine on each side.
Wings. Tegmen ( Fig. 4E View FIGURE 4, A – L , 20 View FIGURE 20 A–B) extending well beyond middle of hind femur at rest ( Fig. 4B View FIGURE 4, A – L ); apex blunt ( Fig. 4A,B View FIGURE 4, A – L , 20 View FIGURE 20 A–B), anterior margin straight, posterior margin slightly concave proximally. Coastal field with an irregular row of large cells, with narrow, irregular cells along anterior margin; anterior margin with a thin yellow stripe; veins of tegmen light green. Wing with radius divided in apical third; cross-veins slightly emphasised by colour; stridulatory file ( Fig. 4F View FIGURE 4, A – L ).
Abdomen. Tenth tergite with cerci turned inwards, concealed on all dry-mounted specimens; caudal margin of tenth tergite not deeply incised; cercus robust ( Fig. 3D View FIGURE 3, A – D ), slightly incurved, apical tooth short, robust about equal in length to internal tooth; subgenital plate shallowly incised ( Fig. 4G View FIGURE 4, A – L ), lateral projections rather elongate; titillator ( Fig. 4J View FIGURE 4, A – L ) weakly sclerotized and enclosed in a sheath.
Female. Differs in considerably larger size ( Table 1 View TABLE 1 ) and in following characters: metanotum with a small tubercle on each side in anterior region; caudal margin of disk minutely tuberculate and feebly incised in the middle; subgenital plate ( Figs. 4K, L View FIGURE 4, A – L ) about as long as broad with a projection at base; apex tapering, acute with a shallow median incision. Ovipositor ( Figs. 4H, I View FIGURE 4, A – L ) minutely serrated on ventral margin near the apex.
Colour. Overall colour green with a number of orange spots on each tegmen ( Figs. 4A, B View FIGURE 4, A – L ); anterior margin of tegmen yellow, this extending to apical quarter. Abdomen creamish white, ringed with green, this rather obscure.

Comments. This species is fairly common on understorey shrubs and saplings along rainforest margins. Males often are carried on the backs of the much larger females ( Fig. 2 View FIGURE 2 , Table 1 View TABLE 1 ). This behaviour has not been noted in other Australian tettigoniids but has been observed especially in the related C. garradunga sp. nov., and C. angularis sp. nov. This behaviour is not uncommon amongst some acridoids such as monistriine pyrgomorphs. Reasons for this pick-a-back behaviour are speculative but could be described as males defending their claim on a female for sexual purposes or using the much larger females to ferry them to food sources.

It is most closely related to C. lampra based on this character. The male cercus is unique in its elongate shape and the projection of the external tooth ( Fig. 6D View FIGURE 6, A – H ); the male phallus (titillator) ( Fig. 6E View FIGURE 6, A – H ) is elongate and very weakly sclerotised. The margin of the plate of the mesothorax is weakly divided in the middle of the anterior margin, each side bearing a series of more or less uniform teeth along the margin. The female supra-anal plate is twice as broad as it is long, the apical margin evenly obtuse and smooth.

Thoracic auditory spiracle minutely circular. Sternum with prosternal processes thickened, close-set, but abruptly narrowing apically. Mesosternum with anterior margin of plates divided and with a prominent tooth on each side, lateral margin evenly tuberculate, posterior margin with an acute projection internally. Metasternum with less prominent tubercles along margins.
Legs. Fore coxa with an elongate spine. Fore tibia with a number of minute spines along both margins of ventral surface; apex armed with a minute spine on each side. Middle tibia armed with 3–4 minute spines on both margins of ventral surface; apex with a minute spine on each side. Hind tibia with approximately 13 minute spines on internal margin of dorsal surface, each separated by a number of stout setae, external margin with 5–6 minute tooth-like spines similarly separated by stout setae, apex unarmed; ventral surface with 6 spines on internal margin, 5 spines on external margin, apex with a single spine on each side.
Wings. Tegmen ( Fig. 6B View FIGURE 6, A – H ) extending to posterior fifth of hind femur at rest; apex acute, anterior margin straight, posterior margin weakly produced ( Fig. 5A View FIGURE 5, A – D , 20 View FIGURE 20 C, D). Costal field produced with large cells, the accompanying veins white. Wing with radius divided in basal third; cross-veins emphasised by colour.
Abdomen. Tenth tergite with cerci turned inwards and concealed on all dry-mounted specimens; caudal margin of tenth tergite not deeply incised; cercus slender, straight, external tooth straight ( Fig. 6D View FIGURE 6, A – H ) about equal in length to that of apical tooth; supra-anal plate ( Fig. 6D View FIGURE 6, A – H ) broadly triangular, apex obtuse, extending to apical quarter of cercus; subgenital plate shallowly incised, the lateral projections short, robust; titillator ( Fig. 6E View FIGURE 6, A – H ) fused, base broad, apex broadly obtuse, very poorly sclerotised.
Female. Differs in considerably larger size ( Table 2 View TABLE 2 ) and following characters: metanotum with a small tubercle on each side in anterior region; tegmen ( Fig. 6B View FIGURE 6, A – H ); wing with cross-veins less emphasised by colour; tenth tergite produced tongue-like, caudal margin smoothly obtuse; cercus elongate, slender directed posteriorly; subgenital plate about as broad as long, without projection at base, apex tapering and with a shallow median incision. Ovipositor with tip minutely serrate on ventral margin ( Fig. 6F, G View FIGURE 6, A – H ).
Colour. Overall colour green with variable number of orange or yellow orange spots on tegmina, variable in position; often one or more creamish irregular large white spots in middle of tegmen. All spotting bilaterally symmetrical. Abdomen ringed with purple, the intensity decreasing caudally.

Comments. This is the smallest known species in the tribe and is very delicate and slow moving. The antennae are extraordinarily elongate, perhaps ten times the length of the body when the antennae are intact. It lives in understorey vegetation as illustrated in Fig. 27 View FIGURE 27 B. This species is common some years and rare in others. As noted previously, females lay eggs in dead wood.

Fastigium of vertex relatively prominent ( Fig. 8A View FIGURE 8. A – H ), but ending before the margin of antennal scrobes; surface with a deep sulcus with sides carinulate. Frontal fastigium replaced by median ocellus. Antennal scape not greatly swollen on internal margin, but carinate, anterior margin of dorsal surface lacking a minute tooth.
Thorax. Pronotum with anterior margin truncate and with tubercles well beyond margin ( Fig. 8C View FIGURE 8. A – H ); lateral margin with 3 blunt teeth; mesonotum with 2 larger teeth, metanotum with 2 more prominent teeth followed by 3– 4 smaller, tubercle-like teeth ( Fig. 8C View FIGURE 8. A – H ); surface of disk cut by 2 sulci, the first sulcus straight, that of mesonotum undulating, disk with multiple small tubercles but those on the anterior portion of disk more concentrated, caudal margin of disk smooth, convex; lateral lobe with dorsal sulci continued, parallel and often connected ventrally but not to ventral margin; pro-, meso- and metanotal surface of lateral lobe each with a few scattered minute tubercles; ventral margin of lateral lobe poorly defined, not raised, undulating and with a few tubercles on margin. Thoracic auditory spiracle minutely circular.

Comments. This species is unlike the others in the genus with the armature of the surface of the pronotum, the spination of the legs and the pitted aspect of the head. It does resemble the others, especially C. lampra , in the minute size of the female subgenital plate and the reduced armature of the tip of the ovipositor.

Holotype male. Labels. 1. “Mt Glorious 635m, rainforest, 22 km NW of Brisbane, S. E. Qld. light Feb. 1985 Anthony Hiller Coll.”. 2. “ ANIC 14-008486”. Holotype deposited in the Australian National Insect Collection, Canberra.
Type locality. The type series was collected on low shrubbery along the rainforest margin.
Differential diagnosis. This new species is very distinctive in size and morphology. The fastigium of the vertex ( Fig. 9A View FIGURE 9, A – I ) bears converging carinae laterally with a distinct tubercle basally. The armature of the pronotum is reduced ( Fig. 9B View FIGURE 9, A – I ) compared to the other species but the sternum bears short, divergent prosternal processes similar to those in T. spininota gen. et sp. nov. p. 24; the meso- and metasternal plates are cup-like and unarmed on their margins ( Fig. 9E View FIGURE 9, A – I ). The shape of the tegmen ( Figs. 20 View FIGURE 20 G, H) in both sexes is proportionately broader than in the other species and the development of the male tenth tergite is unlike that of any other known species in the genus. The broad incision of the male tenth tergite is distinctive as is the shallow incision of the male subgenital plate. The female bears a minute subgenital plate with a small median incision. The ovipositor is unarmed ( Fig. 9H View FIGURE 9, A – I ). The overall colour of the species is green with no distinctive colour spots on the tegmina.

Type species: Tallebudgeroptera spininota Rentz, Su, Ueshima , gen. et sp. nov., here designated.
This species is so distinctive that it cannot be placed in any recognised genus. It is related to Chloracantha on the basis of its overall body shape and shape of its tegmen ( Fig. 20 View FIGURE 20 M). The armature of the pronotum is the key to its placement ( Fig. 10A View FIGURE 10, A – I ). The posterior margin of the disk is heavily spinose, a condition not shared with any other species in the Australian Simoderini . This genus and species is known only from females.
Differential diagnosis. Females. Overall body shape similar to Chloracantha species. Females have the tegmina shaped similar to those of Narea elongata . The antennae are not thickened as they are in Narea species. The supra-anal plate is roundly tongue-shaped ( Fig. 10G View FIGURE 10, A – I ). The ovipositor is robust and minutely, irregularly serrate dorsally ( Fig. 10H View FIGURE 10, A – I ) and the subgenital plate is minute ( Figs. 10E, F View FIGURE 10, A – I ).
General. Body robust, not delicate, of moderate to large size for tribe. Males unknown. Females with distinctive tegmina ( Fig. 20 View FIGURE 20 M), apically acute. Ovipositor thick and heavy, minute, irregularly serrate subapically on dorsal margin ( Figs. 10H, I View FIGURE 10, A – I ).
Head. Head narrow when viewed dorsally, well seated in pronotum, strongly slanting in lateral aspect; frons feebly undulating, bulging slightly below fronto-clypeal suture. Fastigium of frons represented as a minute, low linear carina at the base of the antennal scrobes and with a minute tubercle (median ocellus) on its ventral margin; fastigium of vertex ( Fig. 10A View FIGURE 10, A – I ) short, triangular and with a deep sulcus in the middle and with a minute tubercle (lateral ocellus) at its base on each side. Eyes positioned high on head, moderately bulging, horizontally depressed. Antennal scrobes prominent, pedicel with a swelling on internal surface; occiput smooth, without sculpture, feebly tumid.
Thorax. Pronotum with surface flat ( Fig. 10A View FIGURE 10, A – I ), regularly pitted, surface cut by two sulci, the posterior sulcus forming a distinctive “V” in the middle; anterior margin of disk straight, without teeth or tubercles, posterior margin distinctively spiked ( Fig. 10A View FIGURE 10, A – I ); lateral margins of disk with 2 heavy spikes on pro- and mesozona, metazona with 3 larger spikes laterally; lateral lobes with margins smooth, unarmed ( Fig. 10B View FIGURE 10, A – I ). Thoracic auditory spiracle minute, elongate, not concealed by pronotum. Sternum with prosternum armed with a pair of elongate, slightly divergent spikes ( Fig. 10D View FIGURE 10, A – I ); mesosternum with cup-like lobe, the margins minutely serrate, metasternum with margins smooth ( Fig. 10D View FIGURE 10, A – I ).

Hind femur very elongate, only slightly swollen basally, armed only on outer ventral margin with stout tooth-like spines, emphasized by colour; genicular lobes armed on both margins with a single stout spine; hind tibia elongate, carinate on both surfaces, slightly swollen basally, dorsal surface armed on both margins with relatively elongate spines, ventral surface armed with a smaller number of more slender spines; apex of ventral surface with a pair of spurs, only slightly longer than adjacent spines, dorsal surface unarmed apically.
Wings. Tegmina reaching well beyond apex of abdomen, tegminal venation ( Fig. 20 View FIGURE 20 M) with costal field with irregular cells; costa, if present, very faintly indicated; median and radius parallel for near their entire length and diverging apically. Media Anterior vein most prominent, with regular veins and cells dorsally and ventrally. Hind wing with costa well developed, diverging cephalically apically, subcosta and radius parallel for nearly their entire length.
Abdomen. (Female) Tenth tergite appearing indented; supra-anal plate ( Fig. 10G View FIGURE 10, A – I ) tongue-shaped; cercus short, conical, about ¾ the length of supra-anal plate; subgenital plate ( Figs. 10E, F View FIGURE 10, A – I ) disproportionally small compared to size of insect, produced on each side at base. Ovipositor ( Figs. 10H View FIGURE 10, A – I ) short, robust, feebly serrated subapically on dorsal margin ( Fig. 10I View FIGURE 10, A – I ).
Colour. Overall colour dark green. Most of the original colour is changed due to preservation. Pronotal spikes yellow with tips dark brown. Outer surface of femora appear to have had a brown longitudinal stripe in life.

Holotype female. “ Mt Cougal Upper Tallebudgera Ck S. E. QLD 500m 7 Mar. 1988 G. B. Monteith”. Holotype in the Queensland Museum, Brisbane, Queensland.
Type locality. The collector, G. B. Monteith reports (in litt.) that the type locality is rainforest and Mt Cougal is a rocky pinnacle on the spine of a ridge which runs from the Springbrook Plateau down to the coast behind Coolangatta on the Gold Coast. The border between NSW and Qld actually runs along the same ridge so Cougal is right on the border, and the track to walk to Mt Cougal runs beside the border fence. The katydid was found in adjacent rainforest.
Differential diagnosis. Known only from females. Pronotum with very elongate spines on lateral margin; ventral margin of lateral lobe smooth, with 1–2 minute tubercles or no tubercles at all. Prosternal tubercles widely spaced, divergent. Mesosternum with plates very broad, only feebly notched along cephalic margin; metasternum with plates not defined. Tenth tergite with supra-anal plate tongue-like, about 1.5x as long as broad, apex obtuse; cercus tapering but apically bent, directed inwards. Subgenital plate minute, with shallow, broad median incision. Ovipositor minutely tuberculate, serrulate on dorsal margin near tip.
