Description
This species has a yellowish head with black markings on the first two antennal segments.[4]
O. forbesi is very similar to O. nigricornis. The two species can be reliably separated only by the pulses per second (p/sec) of the male's song.[5]
The male sings by stridulation, and the p/sec increases with temperature.[6] The song of the male below was measured at 55-56 p/sec in temperature of about 15 degrees Celsius (°C).
