 Song. The calling song of this species is unknown.   
 Comments. This species occurs in habitats similar to the other species. It inhabits the weedy vegetation along rainforest margins where it can be found during the day hiding in Pandanus patches or in the axils of tall grasses (Fig. 1 G). The southerly distribution of the species seems to be the area of Krukow Road, Babinda. Intensive collecting to the south of this locality has failed to yield any specimens. Our colleague, Jack Hasenpusch, has been collecting insects in the Garradunga area, south of Babinda, but has not found G. oedicephala (pers. comm.).

Paratypes: Queensland: 10o21’S 142o82’E Sue (Warraber) I., 10.xi.1977, 24.xi.1977, 25.xi.1978, 30.xi.1977, 1.xii.1977, 2.xii.1977, 3.xii.1977, 5.xii.1977, 8.xii.1977, 21.xii.1977, 16.i.1978, 17.i.1978, 18.i.1978, 23.i.1978 (SE Bakker, ED Edwards, J Dowse, RC Lewis, RA Farrow, 6 males, 8 females, ANIC).   
 Comments. When startled and confronted, this species assumes a threat display (Figs. 10 B, C) confronting the source of the irritation head-on with mandibles agape. At the same time the “squeaking sound” is produced from an as yet unidentified source apparently emanating from the head. No other known species of Goodangarkia presents such behaviour. Other species when confronted simply move away or drop to the ground.

 Type locality. The holotype was taken from a stand of Pandanus near the junction of the Capt Billy’s and Bamaga roads.   
 Differential diagnosis. Male. Head. Surface of frons uniformly wrinkled and pitted; median ocellus moderately large, tear-drop shaped; fastigium short, feebly hooked forward, surface not sulcate; eye ovoid, prominent; antennae with scape and pedicel, scape projecting slightly above tip of fastigium.   
 Thorax. Pronotum surface minutely wrinkled, less so in the middle, surface with prominent transverse sulcus beyond the middle, more heavily engraved on shoulders; cephalic margin of disk feebly concave in the middle, posterior margin truncate; lateral lobe broader than deep. Prosternum bearing a pair of relatively short, stout spines; mesosternum with lobes broadly triangular, the outer surface of the posterior margin bearing a tooth; metasternum with a hook or tooth directed outward on anterior margin.   
 Legs. Foreleg with femur spined on both margins of ventral surface with 4–5 spines; tibia unspined dorsally, ventral surface bearing 6 spines on both margins. Middle leg with femur armed only ventrally, with 3 small spines at base of anterior margin and up to 5 larger spines on posterior margin; tibia unarmed dorsally, with 6 spines in apical 2/3 of anterior margin, posterior margin with up to 8 spines along entire length; both sides armed at apex with a much longer spine. Hind leg with femur unarmed on internal margin of ventral surface, external margin with 7, 8 spines mostly in apical half. Genicular lobes of all femora usually bearing a single smooth tooth, although this can be absent from fore or middle femora on one side or the other. Fore and middle coxae bearing a single small spine.   
5. Named with reference to the distinctive shape of the male cercus.  
 Wings. Tegmen (Fig. 11 A, B) bearing a short, irregular costa: subcosta and radius parallel, slightly diverging apically and separated by a few oblique and perpendicular veins; MA with basal fork. Right tegminal stridulatory area with scraper very elongate, gently arching (Fig. 14 E). Stridulatory file (Fig. 13 D) with most teeth about equal in width.   
 Abdomen. Tenth tergite with broad, shallow median excavation; supra-anal plate short, broadly triangular, with deep median sulcus, apex blunt. Cercus with short, blunt apex positioned upwards; internal tooth, dorso-ventrally flattened, with teeth along entire surface (Fig. 11 F).

Titillator (Figs. 11 C, D) bearing feebly sclerotized lateral callouses, main arms serrated on margins.   
 Female. Body slightly larger than male (Table 4). Head slender, not especially prominent or megacephalic. Tegmina extending to or just slightly beyond tip of abdomen to base of ovipositor. Abdomen with cerci slender, directed upwards, apically narrowing; subgenital plate (Fig. 11 E) short, apex truncate.   
 Colour. The colour of G. platycerca is much as described for G. oedicephal a except that males have the caudal margin of the pronotum the same colour as the disk. Less than 10% of the specimens of either sex has been found to have a brown band across the pronotal apex. The colour patch at the base of the tegmen is greatly reduced in this species or completely absent.   
 Song. The calling song is a continuous flickering buzz without breaks unless interrupted by external disturbances (Fig. 17 B).

 Discussion. This species is distinguished by its small size (Table 4) and slender appearance. Males have a distinctly dorso-ventrally flattened internal cercal tooth that is minutely, irregularly serrate on its internal margin.   
Captive females in the laboratory laid eggs in dental cotton tubes that hatched approximately 4 months later. Maturation took some 6 months under laboratory conditions. They were reared on the Orthopteran Food Mix.

 Type locality. The type locality was an area of heath vegetation in rolling hills on gravelly soil. Plants included Xanthorrhoea from which the type was collected (Fig. 1 C).   
 Differential diagnosis. Male. Head. Surface of frons uniformly minutely wrinkled and pitted; median ocellus minute, margins poorly defined; fastigium of vertex stout, well indicated, apex hooked forward, surface not sulcate; eye ovoid, prominent; antennae with scape projecting slightly in front of fastigium, scape produced on internal apical margin.   
 Thorax. Pronotum with surface minutely pitted and wrinkled, shining; surface cut by two transverse sulci, these much more heavily engraved on lateral lobe; cephalic margin of disk feebly concave, caudal margin feebly emarginate; lateral lobe much broader than deep, ventral margin feebly indented in the middle. Prosternum bearing a pair of elongate, relatively closely-spaced, parallel spines; mesosternum cordate, caudal margin strongly acutely produced; metasternum with lobes extremely broad and bearing a hook or tooth directed outward on anterior margin.   
6. Named with reference to the short, stout male cercus.  
 Legs. Foreleg with femur spined with 5 stout spines on each side of ventral surface; tibia unspined dorsally, dorsal surface flat, feebly indented, ventral surface bearing 6 spines on both margins. Middle leg with femur armed only ventrally, with 4 small spines at base of anterior margin, posterior margin of with 5 spines; tibia unarmed dorsally, ventral surface with 9 spines along anterior margin, posterior margin with 5 small spines, apex armed on each side with one of the abovementioned spines. Hind leg with femur unarmed on internal margin, external margin with 7 spines positioned in apical two-thirds. Genicular lobes of fore femur armed only at apex of anterior margin; middle and hind femora armed on both sides, the internal knee often bearing a second smaller spine. Fore and middle coxae each bearing an elongate spine.   
 Wings. Tegmen (Figs. 7 A, C) with very narrow precostal area; costa poorly indicated, subcosta and radius parallel for nearly their entire lengths, diverging apically; MA feebly indicated, obscure. Right tegminal stridulatory area (Fig. 14 A) with scraper strongly arching. Stridulatory file (Fig. 13 F) with teeth relatively narrow, the broadest teeth slightly distad of the middle.   
 Abdomen. Tenth tergite with broad, somewhat undulating, shallow median incision; supra-anal plate very narrow, usually hidden by tenth tergite, surface deeply sulcate and decurved, apex obtuse. Cercus (Figs. 7 D, E) very short, robust, apical tooth very short, positioned upwards; internal tooth slightly inflated, with minute teeth on internal margin. Subgenital plate with median incision relatively deeply V-shaped; style elongate but shorter than one side of median incision. Titillator (Fig. 7 F) with main arms subacute, not armed; ventral sclerites distinctive, each divided into 2 tubercles.   
 Female. Body slightly larger than male (Table 5). Head not especially megacephalic. Tegmina extending nearly to tip of abdomen. Abdomen with cerci relatively stout, densely hirsute, directed upwards; subgenital plate (Fig. 7 G) short, surface feebly engraved, apex truncate.

 Song. The calling song is a continuous stuttering low sound with short breaks every 15–18 seconds (Fig. 17 A). Comments. Like other Goodangarkia species, G. brevicerca is common and associated with rainforest margins and grasslands. It has been found hiding in the base of Pandanus during the day. After dark the katydids emerge to forage on a variety of plant and animal material.   
 G. brevicerca has been reared in the laboratory through 2 generations. This katydid readily consumes the Orthoptera Food Mix and requires some 6–7 months to mature at 25o C.
