Oecanthus nigricornis
The shaded area shows the combined
distribution of Oecanthus nigricornis and Oecanthus
forbesi, two species that thus far are separable only on the basis
of the calling songs of the males. Dots show county records of
O. nigricornis that are based on tape-recorded males.

based on specimens only or on the literature are either O. nigricornis or
O. forbesi.
