Barbaragraecia gen. et sp. nov. p. xx

2(1) Ovipositor ensiform, straight or gracefully upcurved......................................................... 3 Ovipositor falcate, either strongly directed upwards or gracefully arching......................................... 4

3(2) Colour green or brown, attenuate rainforest species; fore tibia with dark spots near auditory foramen........................................................................................... Greenagraecia gen. et sp. nov. p. xx Colour variable but not green; robust non-rainforest species; widespread in tropical Australia......... Nicsara Walker , p. xx

4(2) Colour straw brown or light grey brown often with blue-green lines on frons and genae; living in or around grasses............................................................................................ Secsiva Walker 1869 Colours variable but not as above........................................................................ 5

5(4) Stridulatory region of tegmen wholly concealed underneath posterior margin of pronotum…..........................6 Stridulatory region of tegmen exposed, not concealed by pronotum.............................................. 8

6(5). Head with dark brown stripes or lines beneath eyes ( Figs 6A, C )................. .. Larifugagraecia Rentz & Su gen. nov.

Head without stripes of markings on genae beneath eyes...................................................... 7

Geoffagraecia gen. et sp. nov. p. xx Size generally larger; male phallic complex with titillator not enclosed in a hood, apically acute (see Rentz & Su 2019, Figs 4F , 6G ).
