Found as pupa between dirt from saltmarsh on Ameland (Netherlands) around march/april 2016 Dorylomorpha seems right to me, but looking at the shape of the ovipositor is has a resemble with D. canadensis. I only have a very old key from Pius Sack (1935),so no description of D. canadensis wich is found in 1943 by Hardy.

The basal segments of the abdomen contain a tuft of pale/yellowish hairs, so maybe it could be D. xanthopus..... |

The description of female canadensis (http://www.biodiv...item/21984 page 133) describes the abdomen: "Sides of abdominal segments two to four and all of the venter, bright yellow, interrupted on the dorsum by broad black spots."

I normal do no Pipunculidae (only Anthos..), so a strange side way for me. D. canadensis is Nearctic, wich I know now, thanks to you. I studied Sack again and D. xanthopus seems a good option for now, the descriptions of the typical characters fit. Also the last antennal segment is black in D. canadensis, so it would be wrong after all. (would you like to have the European key from Pius Sack from 1935 in pdf….it is old and not very updated, but with good descriptions of the species though). Johanna |

D. xanthopus should be right. The best paper around to ID this genus is Anders Albrecht's revision of 1990 (Acta Zoologica Fennica 188) |

Thanks to Paul who was so kind to send me the revision, we have the right name: Genus Dorylomorpha; subgenus Dorylomyza and indeed xanthopus.... By the way, D. canadensis seems holartic. Johanna |
