urn:lsid: Orthoptera.speciesfile.org:TaxonName:5266. New Synonymy.
Type locality. There is no further data on the collection of the type series of N. compacta. The type series consists of two males in good condition but darkened in colour due to age and poor preservation. The left hind leg is missing on the lectotype. The antennae are heavy as is characteristic for Narea species.
Comparison of the figures provided on the OSF and the Museum für Naturkunde, Berlin websites leave little doubt as to the synonymy of the two taxa. Curiously we have not collected this species during the course of this investigation nor is it represented in any of the collections studied by us. It is similar in some respects to the new species described below but the proportions of the male tegmen are quite different between the two taxa, see Table 6. In N. compacta the tegmen length to width ratio is 2.5. In N. kungaree, sp. nov., the ratio is 3.2–3.5. In addition the venation is decidedly different, compare Eades et al. (2014) with Figs. 11. The entry in the Registry in the Natural History Museum, London, number 58–124 for N. compacta records “Sidney and Moreton Bay” as the localities for the types. It also states that they were collected by Edward Dåmel and bought by Samuel Stevens.” The two localities are separated by great distance and several mountain ranges and the Moreton Bay record (Brisbane) seems incorrect. The occurrence of other Narea species in the vicinity of the Jenolan Caves and the south coast of New South Wales suggests that they came from the vicinity of Sydney. No additional material of these taxa has been seen by us. However, colleague Roger Farrow photographed a male (Fig. 11) of what could be this species at 3 km south of Big Badja Hill on the Badja Fire trail in Deua National Park, NSW. The specimen was not collected and appears different from N. kungaree sp. nov., a species known from few specimens from the north of the Deua National Park. It may also have been an individual of the species described below.

Type locality. The type locality is typical coastal mixed wet sclerophyll woodland. There is no information on the actual collection of the holotype.
Differential diagnosis. The elongate, slender tegmen coupled with its rounded or obtuse apex is highly distinctive of this species. In addition the MA vein of the tegmen is very prominent in this species, whereas it is very poorly, if at all defined in N. compacta, compare Figs. 12A–L. This species seems closer to N. compacta than N. elongata based on these characters and the structure of the male genitalia. The male cercus is uniquely short and compact and directed inwards. Unfortunately, we have no males of N. elongata with which to compare this character. Females of N. kungaree, sp nov. are very distinct from those of N. elongata in size (Table 6), shape of tegmen (Fig. 12A, 20 I) and shape of the subgenital plate (Figs. 12H, I). The ovipositor of this species is more slender and relatively shorter than in N. elongata (see Table 6).
6. Kungaree is an aboriginal word meaning knife, an allusion to the elongate, sharp, titillator of the male of the species.
General. A small slender species, smallest known for the genus, with a distinctively elongate tegmen with an obtuse apex in both sexes.
Male. Head. Frons not concave when viewed laterally, surface smooth, not shining, genae not at all swollen. Fastigium of vertex (Fig. 12B) triangular, with a relatively deep median furrow and lateral carinae with a low tubercle at base. Antennal scape elongate, twice as long as broad, without ornamentation; pedicel and flagellum very heavy.
Thorax. Pronotum with anterior margin straight to feebly obtuse, without tubercles; prozona with surface sparsely, regularly tuberculate, laterally with 3 teeth, the anterior two smaller than the posterior (Fig. 12B); junction between prozona and mesozona with a straight, shallow transverse sulcus; mesozona with surface similarly sparsely and uniformly tuberculate, median carina faintly indicated and a minute “A” shaped impression anteriorly; junction between mesozona and metazona with an undulating shallow sulcus, somewhat “V” shaped in the middle; metazona uniformly tuberculate, the tubercles more numerous and much denser in the apical portion of the segment, lateral margins with 2 large teeth followed by 1–3 much smaller teeth. Lateral lobe of pronotum sparsely tuberculate and bearing 3 distinctive sulci (Fig. 12C), anterior and posterior margins oblique, the posterior margin bearing a few tubercles; ventral margin straight, tuberculate. Thoracic auditory spiracle elongate, almost concealed. Sternum with prosternal processes flattened triangular (Fig. 12F), apically feebly divergent; meso- and metasterna with plate unadorned and relatively shallow (Figs. 12D).
Legs. Fore coxa with a very minute spine (Fig. 12E). Fore tibia unarmed dorsally and with many small spines on both margins of the ventral surface, one apical on each side. Middle tibia unarmed dorsally but carinate on each margin, ventral surface armed on each margin with many small spines, those on the anterior margin much more numerous than those on the posterior, a slightly larger apical spine on each side. Hind tibia armed on dorsal surface with many small spines, those on the internal margin much more numerous than those on the outer; ventral surface sparsely armed on both margins with a few small spines, apex with a small spine on each side.
Wings. Tegmen (Figs. 20 I, J; 12G) extending slightly beyond apex of hind femur at rest; apex rounded, anterior margin generally straight but feebly arching apically, posterior margin slightly indented in the middle. Costal field with elongate, mostly quadrate cells all slanting caudally, central portion of cells opaque, veins green. Wing with costa and subcosta parallel for nearly their entire length, radius furcating nearly at base; cross veins light brown.
Abdomen. Tenth tergite (Figs. 12H, I) with cercus very short, stout, less than 1.5 times as long as basal width, apex strongly incurved and bearing a stout but apically acute tooth; caudal margin of tenth tergite indented but not deeply; supra-anal plate (Fig. 12I) very elongate, slender. Titillator (Fig. 12J) with arms joined, apically clothed in unsclerotised sheath, apex acute, unsclerotised. Subgenital plate (Fig. 12I) short, stout, apex with a shallow Vshaped median incision.
Female. Differs considerably in much larger size (Table 6) and following characters: Surface of pronotum more sparsely tuberculate; teeth of lateral margins shorter, more robust; tegmina and wings much more prominent, extending well beyond apex of hind femur at rest. Abdomen with supra-anal plate well developed, ovoid but apex acute; cercus elongate, slender; subgenital plate quadrate, with median carina, lateral margins raised, posterior margin feebly indented. Ovipositor (Fig. 12K) very robust, serrate subapically on dorsal margin (Fig. 12L).
Specimens examined. Paratypes: New South Wales: Moodong Ck., 20 km S. of Major’s Ck, 25.ii.1979 (E. D. Edwards, 1 male, ANIC). Parker’s Gap, 8 km SE. of Captain’s Flat, 22.ii.1956 (M. J. D. White, 1 female, ANIC). 11.2 km W. of Rosebank, 518 m, 8.xi.1961 (I. F. B. Common, M. S. Upton, 1 second instar male, ANIC). Victoria: 37O51’S. 145O45’E Powelltown i.1971 (Forest Communities Prog. Aerial spraying, 2 females, 2 female nymphs, ANIC, MUSV). 6 km SSE of Powelltown, 6.iv.1961 (K. L Taylor, Z. Mazanec, 1 male 3 females, ANIC). Tarago River, 12 km SE. of Powellton, 28.ii.1962 (Z. Mazanec, 1 female, ANIC).
Comments. A small species that seems to be very uncommon. The shape of the tegmina and the details of the male and female genitalia distinguish it from other Narea species.
