Hi, I wonder if anyone has a clue of the id. of this sympathetic small fly couple in a dark part of the rainforest close by the river in a rainforest of Paraty-Brazil in January of this year.. My pics are not the best but maybe a family is possible? Thank you! Myriam bonitin attached the following image:  [81.82Kb] Edited by bonitin on 30-12-2010 17:00 |

Syrphidae, so not a bad idea to put them in the Syrphidae forum

Hmm, are we sure that they're not phasiine tachinids?

The huge calypters are visible on picture 1. Tachinidae, Phasiinae they are.

It is great. I can see them, Stephane. You are right. I looked at the eyes on the 2nd photo and would swear that they are Scaeva-like. Proof again that as a non specialist you have to keep your mouth shut

Thank you all for your help! Very much appreciated! So Tachinidae, Phasiinae it will be! Myriam  |

Yes, they look like typical neotropical phasiines - potentially Trichopodini, even though I can't actually see leaf-like bracts on the hind legs. The dusting on the thorax is very typical on that group and the general shape and colour reminds me of a few species that I saw in the BMNH this year EDIT: if you look at this tray of Homogenia sp. you can see similarities.

Yes, they look very like Homogenia sp. to me ... though the status of neotropical phasiine taxonomy (like most tachinids) is very chaotic and needs complete revision to work out which genera and species are valid and which are synonyms.
