Description: SEE TAbLE 1 fOR mORPHOLOGICAL CHARACTERS Of THE HOLOTYPE , AND FIGURE 4C–D AND APPENDIX 1 fOR PHOTOGRAPHS Of LIvE SPECImENS. Colouration: THE bASE COLOURATION IS GREEN (OCCASIONALLY GREY) wITH RED OR YELLOw LATERAL fACIAL STRIPES ON A PLAIN wHITE bACkGROUND. LIkE W. flavolineata sp. nov. IT HAS A bRIGHT YELLOw TO ORANGE mEDIAN fACIAL STRIPE AND ORANGE OR RED PATCHES ON EITHER SIDE Of THE THORACIC TERGITES. LIkE W. whitei sp. nov. IT HAS LATERAL YELLOw STRIPES ALONG PRONOTUm AND AbDOmEN, THOUGH NOT AS INTENSE . Diagnosis: THE kARYOTYPE, wITH 2 n ♀ = 15, DERIvES fROm THE COmbINATION Of THE kARYOTYPES Of W. whitei sp. nov. AND W. flavolineata sp. nov. AND IS UNIqUE wITHIN THE GENUS wITH THE EXCEPTION Of W. virgo . IT CAN bE DISTINGUISHED fROm W. virgo AND OTHER mEmbERS Of THE GENUS bY COLOURATION, AS DESCRIbED IN THE kEY bELOw. Distribution and seasonal cycle: ITS DISTRIbUTION EXTENDS fROm jUST SOUTH Of KALGOORLIE, TO THE EAST AS fAR AS ZANTHUS AND SOUTH TO THE vICINITY Of BALLADONIA ( FIG. 1A & D ), SPANNING A LONGITUDINAL RANGE Of 121.48°E TO 123.53°E . THIS SPECIES REACHES HIGHER LATITUDES THAN ANY OTHER mEmbER Of THE GENUS, SPANNING A RANGE Of 30.97°S TO 32.31°S . IT IS STRICTLY UNIvOLTINE, wITH AN ObLIGATE DIAPAUSE THAT IS bROkEN bY EXPOSURE TO COLD (KEARNEY, UNPUbLISHED). Material examined: 1 fEmALE, 9km WNW Of NEwmAN ROCk, NR.

Biology: Warramaba ngadju sp. nov. IS AN ALL-fEmALE PARTHENOGENETIC SPECIES RESULTING fROm HYbRIDISATION EvENTS bETwEEN fEmALE W. flavolineata sp. nov. AND mALE W. whitei sp. nov. ( HEwITT 1975 ; WHITE et al. 1977; KEARNEY AND BLACkET 2008 ). IT STRONGLY RESEmbLES W. whitei sp. nov. mORPHOLOGICALLY, ESPECIALLY THE mORE SOUTHERN POPULATIONS Of THE LATTER. THIS SPECIES mAY OCCUR SYmPATRICALLY wITH W. virgo AND AT SOmE SITES CAN bE fOUND ON THE SAmE fOOD PLANTS. IT mAY OCCUR IN NARROw PARAPATRY wITH W. whitei sp. nov. IN THE vICINITY Of SPARGOvILLE (WHITE AND CONTRERAS 1979 ). IT HAS bEEN fOUND ON SHRUbS AND TREES Of THE GENERA Acacia AND Senna .
