So you know the chromosome number of _D. occidentalis_? If you
really do, please tell it to me. It has AFAIK not been published yet.
*Equal* ploidy in the context above means equal number of
chromosomes. For the mentioned hybrid this would mean that _D.
occidentalis_ would require to have the same chromosome count as _D.
nitidula_ (in the form Lowrie & al. erroneously regarded as subsp.
omissa, distinctly different from the type of the latter taxon), i.e.
2n=28.

Difficult to tell with a missing chromosome count.
Kind regards
