Which Drosophila could this be? I get stuck with the key in Baechli et al. 2004 Beer Trap (23-25)-8-2020 in park Almere, Netherlands. Thanks in advance https://waarnemin...199112649/.    |

Abdominal pattern of this specimen is somewhat peculiar, perhaps because it is still a bit teneral. However, oviprovector shape and 4v-index (about 1.0) show that it is D. funebris. |

Thank you! I got stuck in the key at that species, but this one was different from normal specimens of D. funebris, that's why I thought I was wrong. p.s. What is the 4v-index? |

4v-index is the length ratio of the apical section of M1 to the preapical section of this vein |

I would have guessed Hirtodrosophila confusa! |

Sorry, this specimen confused me. It is H. confusa - nomen omen. |
