See Also

O. cornuta and O. simulans are very similar in most color and morphological features. Were it not for the leg color characters (O. cornuta, femora red with apices and remainder of legs black; O. simulans, femora red throughout with tibiae red basally, black apically), they would be difficult to separate. (1)

In most spmns of O. simulans the third antennal segment is clearly shorter than is the fourth, but in O. variabilis the third segment is nearly the same length as the fourth antennal segment. (1)
