The second—"O. illudens clade"—includes O. illudens and O. mexicanus. ….

Mating experiments by Petersen and Hughes (1998)Go revealed high intercompatibility between O. olearius, O. olivascens and O. subilludens. In the case of O. illudens and O. nidiformis they reported a little intercompatibility with every other species…
