Nannocyrtopogon sp., male. One of the 18 spp. with tubercules on the frons/vertex -- like N. richardsoni -- but need more details for positive ID.

Mark -- if you have more photos (or same one - at higher resolution), it might be possible to confirm sp. ID on this fly...


No other photo

Thanks Mark! Your photo is nice, with fine detail, but I still need more angles of the face (to clearly see the felt-covered tubercules and raised ridges). Also would need to see the pattern of the spots on the abdomen (underneath the wings).

I can see enough detail to believe your fly is close to richardsoni but likely not that sp.; probably it is an undescribed sp.

Moved from ID Request.

a place to start anyway
