Rem.: For Al-Yamani & Prusova the specimens, both females and males, are very similar to O. simplex Farran,1913 in a body and rostrum shape, Md and P1-P4 armature. Present specimens are distinguished from O. simplex by their bigger size, proportional lengths of prosome and urosome and in basipod 1 of A2 with 1 short small seta on outer margin both in female and in male.
