Holotype male.—Labels 1. “ 28°27’S. 152°54’E. Moore Park , Richmond River , 27 km E. by S. of Woodenbong, NSW 21.xi.1983 (DCF Rentz, MS Harvey, Stop 62)”. Holotype in Australian National Insect Collection, Canberra GoogleMaps .

Male.—Size small for genus ( Table 1 View TABLE 1 ). Head with fastigium of vertex sulcate, sides evenly rounded, surface triangular or diamond-shaped, lateral margins swollen, thicker proximally; frons with surface of clypeus flat. Pronotum with caudal margin of disk truncate, lateral lobes with anterior margin straight, posterior margin acute to obtuse in the middle, ventral margin evenly rounded to subtruncate. Tegmen with principal veins in the costal region parallel ( Fig. 5E View FIGURE 5 ); subcosta and radius parallel and continuous, somewhat diverging apically, the former slightly thicker than the latter; subcosta with Rs feeble and faint, diverging posteriorly, divided well beyond the middle; MA strong, not divided apically; radial area with principal veins parallel and relatively narrowly separated; stridulatory region weakly sclerotised, distal portion of stridulatory vein lacking a recurved hook ( Fig. 5E View FIGURE 5 ), file ( Fig. 7D View FIGURE 7 ). Abdomen with tenth tergite with apex obtuse, cercus arching gracefully, apex divided, in situ cerci often clasping apex of subgenital plate. Male cercus apically bifurcate ( Fig. 6F View FIGURE 6 ).

Female.—Pronotum with caudal margin more deeply emarginated. Abdomen with subgenital plate with a shallow U-shaped median incision, cercus short, stout, evenly incurved. Ovipositor protruding from tip of abdomen.

Colour.—Head green dorsally and laterally with following exceptions: frons, including clypeus, light brown, labrum grayish brown genae green below and around eyes, outer margin bright yellow, occiput green with brownish tinge; area delimited by ocelli light green; antennal scape and pedicel uniformly light green, flagellum reddish brown, with faint light brown widely spaced annulations only apically. Tegmen uniformly green, stridulatory region green ( Fig. 2 View FIGURE 2 ), a small area between subcosta and median black at base, yellow laterally; portion of tegmen protruding just beyond pronotum brownish, lateral portion at humeral angles black. Forelegs light reddish brown with greenish overcast, ventral margin of femur green at apex; middle legs with femur greenish yellow, apex dark brown, tibia brown dorsally, lateral surfaces light green; hind legs with femur green, ventral surface yellow, apex with a pair of brown rings, tibia uniformly green. Abdomen dorsally yellow brown, lateral portions green with purple longitudinal streaks on each tergite, ventral surface uniformly straw brown.

Eggs. Eggs disk-like and dark brown or black. They have not been seen in nature but are probably laid in cracks in bark.

Specimens Examined (Paratypes): New South Wales: 28°27’S. 152 o 54’E. Moore Park, Richmond River , 27 km E. by S. of Woodenbong, 21.xi.1983 (DCF Rentz, MS Harvey, 2 males, some collected as nymphs, matured in laboratory 24.x.1983, Cytol. Prep. 83-174, Stop 62). GoogleMaps 30°08’S. 152°49’E. 1260 Road , Bagawa St For. 12 km SW. by S. of Glenreagh, 17.xi.1985 (DCF Rentz, MS Harvey, Stop 52). National Park , Dorrigo , - ii.1968 (N. W. Frazier, 1 male, ANIC). GoogleMaps Queensland: Mt Tambourine, 6.V.1929 (H. Hacker, 1 female, QMUS). 5 km SW of Canungra, 24.iii.1992 (Monteith, Janetzki, Lovis, Griffin, 1 male, QMUS). Mt Glorious, 22 km NW. of Brisbane, 635m, 14.iii.1979 (A.Hiller, 1 male).

Song.—This species sings with a buzz. One male initiates a bout of singing with a group of males singing for about 30 seconds. A lengthy pause is follows and then another male initiates another bout.

Discussion.—This species is highly localized and was discovered living in small isolated groups. It was found feeding on an introduced ivy which covered most of the native vegetation. The katydids were active after dark and not uncommon at the type locality. At Sawpit Creek, 23 km E. of Woodenbong GoogleMaps , 28°22’S. 152°51’E., the species was heard high in understorey vegetation but out of reach. There GoogleMaps is a single male of this species labeled “ Australia: QUEENSLAND Lemington Nat. Park, 900–1000m, 16–18.II.1964 J. Sedlacek collector Bishop Museum ”. We assume Lemington actually means Lamington. In either case, this is such a disjunct distribution for the species that I am reluctant to include the specimen as a paratype since it may have been mislabelled.
