Pharnacia sp. ???

  Please help me to identify this species.  My friend says that the hatchlings look identical to  Pharnacia acanthopus (pictured on Cedric's site) as nymphs, but the adults are brown while other cultures of P. acanthopus have been green???  In the picture on the right, the left 3 ova are Pharnacia ???, and the right 3 ova are Pharnacia cantori.  Any help is appreciated!
