Thank you Stefan, the only Sympycnus I've seen here so far is S.pulicarius, maybe one of those? Regards Roger |

Why not S.pulicarius? Sympycnus pulicarius (Fallén, 1823) and Sympycnus annulipes (Meigen, 1824) were synonymized by Meuffels (1981), who found a gradual transition from the longer third antennal segment of S. annulipes to the shorter third antennal segment of S. pulicarius, examining specimens of populations of different localities, mainly in the Netherlands. Later Cole (1990) commenting paper by Beuk (1990) has noted that in the British fauna mainly intermediate forms are present, but showing also a taxonomically insignificant variability in the hind tarsus morphology and even in the male genitalia. Later nobody provided key characters to distinguish different forms. In addition, nothing is known about ecological difference between those phenotypes; therefore, I consider the two names belonging to the same species, S. pulicarius. Igor Grichanov |

Thanks Igor...No reason for it not to be S.pulicarius, only enquiring if it might be  . I had a female ID'd by Kahis a while back (Gallery), so now I have both sexes  Regards Roger PS; Which BEUK (1990)?? |

Dear Thomas, Also notice that Parent (1925) described a species, Sympycnus desoutteri, that corresponds with most of the specimens I have collected in Belgium. Also know that Peter Chandler (UK) informed me some time ago that at least two morphologically different forms exist in the UK, but no attempt has been made thus far to work this mess out. Cheers, Marc |

Correct this time: of course, I mean Roger, not Thomas. Must be the late hour. Cheers, Marc |

I think I related some of Meuffels findings on i]Sympycnus[/i]. I may have the actual text somewhere,,, Paul - - - - Paul Beuk on https://diptera.info |

Thanks Marc...no need to apologise regarding my name...I think I've given every combination of the lettering of your name in the past, as anagrams. My Checklist has S.desoutteri but as per; http://diptera.in...d_id=23039 I changed it. So Paul, 20 years ago you were writing articles for the NDRS. Did you use coloured crayons or chalk? Time to dig out the text. Regards Roger |
