Diagnosis: THIS SPECIES IS THE ONLY mEmbER Of THE GENUS TO EXHIbIT THE ANCESTRAL mORAbINE kARYOTYPE Of 2 n ♂ = 17 AND 2 n ♀ = 18, AND AN XO SEX DETERmINING SYSTEm. IT CAN bE DISTINGUISHED mORPHOLOGICALLY fROm OTHER mEmbERS Of THE GENUS bY A COmbINATION Of THE RELATIvE PROPORTIONS Of THE SUbGENITAL PLATE AND COLOURATION, AS DESCRIbED IN THE kEY bELOw.
Distribution and seasonal cycle: THIS SPECIES IS THE mOST INLAND AND NORTHERLY-DISTRIbUTED IN THE GENUS, SPANNING A LATITUDINAL RANGE Of 20.35°S TO 29.65°S AND EXTENDING INLAND AS fAR AS 122.78°E. NYmPHS AND ADULTS CAN bE fOUND AT ANY TImE Of YEAR (KEARNEY, UNPUbLISHED).
