I used to think this was P. milbertii, though now I wonder if it's not simply a dark P. brevipennis.

Moved from Proctacanthus.

In Hine's key there isn't muc
In Hine's key there isn't much to separate the females of these two except for size and the dorsal markings on the thorax, neither of which can be told from the photo. But brevipennis has "occipito-orbital bristles mostly black" Your photo shows all white bristles, and my specimens of brevipennis all have black bristles there (Unfortunately I don't have milbertii specimens to compare). The photos I see of milbertii show white bristles as in yours,so I lean towards milbertii.

Thanks Paul. I think I had keyed this out years ago, but I didn't remember the details.
