Thank you Katerina for responding, In the Netherlands there are three species of Pseudolyciella; 1. Pseudolyciella pallidiventris (Fallén, 1820) 2. Pseudolyciella stylata Papp, 1978 3. Pseudolyciella subpallidiventris Papp, 1978 These species can only identified by male genitalien. Other species I found in the forest, where called P. cf. pallidiventris. Do you think it's P. cf. pallidiventris? Or is Pseudolyciella sp. much better? greeting Robert, Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

Species have been found together. It will remain 'sp.' Although the male genitalia of the separate species as given in their (re)descriptions are distinctive, I am under the impression that intermediates in shapes exist. Paul - - - - Paul Beuk on https://diptera.info |

thank you for your answer Paul, Species have been found together. It will remain 'sp.' Pseudolyciella pallidiventris and Pseudolyciella subpallidiventris? ? Or is it for all three species; 1. P. pallidiventris, 2. P. stylata Papp and 3. P. subpallidiventris? (I'll ask this, trying to make a better administration on waarneming.nl of this group/species) Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

In general: On one site more than one Pseudolyciella can occur, so there is no guarantee that once you have found one species at a certain date, that you will find the same species the next time. Without a voucher specimen or an extremely lucky shot that shows male genitalia, all pictures will remain Pseudolyciella sp. or Pseudolyciella pallidiventris group (sp.). In the Netherlands that is the same. Edited by Paul Beuk on 05-11-2009 15:01 Paul - - - - Paul Beuk on https://diptera.info |

Thank you Paul, I'll not separate these species in groups then, but put them together in the: - Pseudolyciella sp. greeting, Robert Greeting, Robert Heemskerk ---- WWW: http://robertheem...ndedag.htm --- |

Like Paul, I'm under the impression that intermediates exist. So even if you have collected the specimens and you're dealing with male specimens it's not certain you can positively identify the material. I found several specimens in beer trap samples of the last few weeks, but only females
