A species ID would need a brighter, sharp picture and a lot of luck. |

It seems to me that in 2nd photo there are rows of about 20 pv setae on t3. If so, it is Delia platura. Nikita Vikhrev - Zool Museum of Moscow University |

Wow Nikita!!! You're amazing!!!! Zillion thanks!  Really, an introduced anthropic exotic species makes sense in the place where I've photographed it

There are several presumably native species in South America closely related to Delia platyura. As of 1993 only one was described: D. sanctijacobi. According to the key by Gomes et al. (2022) (http://dx.doi.org....80.e82831) the eyes of D. platyura and D. sanctijacobi are closer togther ("frontal vitta usually obliterated at narrowest point of frons"). |

Then is probably Delia sp, but not platura? Thanks! |

1. Not Delia sp., but species of D. platura group. 2. I'm not very convinced by Gomes et al. (2022) publication. Authors divided D. sanctijacobi from D. florilega by COI sequence. In the morphological key they have not even compare D. sanctijacobi with D. florilega. Thus, D. sanctijacobi is a species described by COI sequence only, without any morphological confirmation. 3. I cannot see any trace of a brush of long dorsal setae on the first tarsomere of mid leg (the main diagnostic character for D. sanctijacobi and D. florilega).

Thanks a lot, very useful Nikita! I deeply disagree in taxonomy based on genetics only - it's completely unreliable. I would not considere valid none species described by sequences only. |

Griffiths compared morphology of all three species in his revision of Nearctic Delia. |
