A friend is stuck, and so am I. Could anyone do a kindly ID please.
It is a "small" (I interpret that as probably 2mm to 5mm length) fly that showed up at a light.
The location is at Danielskuil in the Northern Cape in South Africa. Google earth's decimal coordinates are about -28.2, +23.55
Someone proposed Muscidae, and I cannot argue, but I have never seen such a decorative Muscid.
Remarks welcomed with the usual respect and gratitude
Jon

Thank you Nikita.
I am not familiar with Neomyiia nudussima and I cannot find much material on the species. I notice that most of the texts I can find spell it Neomyia; do you happen to have a definitive source?

Sorry, my misprint, correct is Neomyia. The previous name of this genus was
Orthellia.

Ah, thanks Nikita. Someone at this end had suggested Orthellia, but without suggesting the actual species.

Nikita, thank you for your efforts so far, and sorry to be a pain, but I made an inquiry and got a size estimate of of 3 to 4 mm, based on a count of the threads in the fabric.
I am not familiar with Neomyia nudissima ; do you think that is a plausible size? Also, such pictures as I could find of (alleged) Neomyia showed no obvious dark areas, whereas my source confirmed that the live specimen did actually have such markings.
Any comments would be welcome, either from you or anyone else.

I'm not insist on Neomyia nudussima by photo. N. nudussima is common and small and scutal chaetotaxy on photo fits it. But there are a lot of other possibilities in Africa, for example, Pyrellia.

Thank you John and thank you Nikita. I reckon Neomyia nudussima will do for our purposes. I'll alter the title accordingly.
