Maybe Sapromyza sp. Li Shi rich biodiversity in China. shililauxaniid@aliyun.com. Einstein once said: "Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world." |

Thank you for the suggestion Li Shi. These I suspect are difficult to identify, I recently came across Minettia plumicornis in the gallery and thought it could be that? |

I can not decide it because I identify some species from the Oriental Region. So I can not give you a correct answer.

No interalar setae -> Sapromyza.

Thanks Paul! You were correct with Sapromyza sp. Li Shi. I guess it's not possilbe to get it to species level? We have 7 Sapromyza sp. here, S. albiceps, apicalis, halidayi, obsoleta, opaca, sexpunctata, zetterstedti. I think S. sexpuncatata can be ruled out, I think I have that one too. I found a pic of Sapromyza apicalis on this site which has dark antennae tips, not sure about the rest though. I have pics from June of a paler one which looks similar. http://www.dipter...d_id=20611 |

Letīs use elimination and see where it gets us... albiceps (male) should have frons and face white and a single pair of orbital bristles apicalis should have darkened third antennal segment obsoleta should also have darkened third antennal segment opaca should have three tergites with black spots sexpunctata should also have three tergites with black spots zetterstedti should have one pair of black spots on the abdomen halidayi could be an alternative, but should have yellow palpi, this flyīs palpi are obviously dark... This leaves us with... nothing. It might be something not on your list - but I am not an expert! In summary: always collect, and donīt trust checklists! |

viktor, You are a great man with rich experience on Sapromyza spp. . These identifying characters are helpful to me and other people. I believe your summary: always collect, and don't trust checklists! Support it!

It could be intonsa but Katka might be able to tell more.

shililauxaniid: Thanks, but I am really just a beginner! Just started looking at these Lauxanids last year. I havenīt seen all these Sapromyza species (but I hope I will someday!), but simply used the keys in Shatalkin (2000) to see if there where any particular couplet that strongly eliminated each species. I learned a lot from it and Iīm happy if you learned something too! |

Hi, I think fly in picture 1-3 have dark end of antenae, but fly at fourth picture not. So that 1-3 Sapromyza obsoleta group, 4 may be Sapromyza intonsa group or somethink else, it is very bad visible. Katka |

Thank you all for the input, Victor that list of characters to look for might prove useful! Thanks Katka, I was hoping you would appear. It looked to be one of the two as listed by Victor with dark antennae tips.Is it safe to put the first fly in the Gallery as Sapromyza obsoleta group? There are none at the present so would make a useful addition. |

Hi, i thing it is not for the gallery, the darkness of antenae is very light, so that it is not a typical specimen. Katka |
