Hi, I've found this creature in San Isidro, Buenos Aires. I'd like to identify it. At first sight, I thought it was a Blepharepium sp, but there are some significant differences, as the lack of a clear border in each abdominal segment Regards Diego A.

From your photo, looks like Diogmites coffeatus; but I can't be certain, as I need more detail & angles. That sp. mimics dark vespidae and has similar coloration to this one. |

Thanks, Eric for your reply. Yesterday I found it again in the same areas and I could take more pictures. Hope they are good enough to see more details. https://drive.google.com/open?id=1GTLI-Kqt_s7-7OVcZ8khcObjHljhEjbV https://drive.google.com/open?id=1_0SdfDMCkl-qU8zs6yYyiqkHNKS3u2mb Regards Diego Rosa Diego A.

This is something from the tribe Plesiommatini. The eyes diverging ventrally are a very good character for this tribe. Compare with http://www.hr-rna.com/RNA/Rfly%20pages/Plesiomma%20page.htm I don't think Plesiommatini has been recorded from Argentina, but Cystoprosopa semirufa was described from Montevideo, Uruguay. I'll have to look into the literature to see if I can get some more info. Great find! Edited by Chris Cohen on 15-02-2019 23:45 |

Yes, I now can see that this is a Plesiomma sp. I haven't been able to open the supplemental images that Diego sent (show view of face?) but after Chris mentioned this genus, the overall shape & impression now says "Plesiomma" to me also. Cystoprosopa is a closely related genus but has a 'fatter' head and shorter antennae than this fly. Cheers, Eric |

Yeah, one of the additional images had a view of the face. I can't seem to attach or embed it, annoyingly.
