Hello, This Brachycera has been collected in a yellow pan trap in coastal area of Moorea, in French Polynesia. I have no idea of its family, is it possible to tell based on this picture ? Thank you for the help ! Tramage attached the following image:  [122.86Kb] Edited by Tramage on 17-09-2025 07:40 |

I think Ephydridae. |

Based on your remarks, I've searched for Ephydridae Discomyzinae for the region, and Discomyza maculipennis (Wiedemann, 1824) can be a good candidate, based on the habitus and wing pattern. This species is already reported from French Polynesia too. |

Could be - it would be worth removing the specimen from fluid and drying it, to see whether the characteristic reticulate pattern of the thorax of D. maculipennis is restored.

I dried some specimens and they do agree with the thorax pattern of D. maculipennis. Thank you for the help. |
