This big Fanniid comes from a forest south of Amersfoort, Netherlands. It is about 12 mm long, and the strangest features are two long spines on the katepisternum between coxa 1 and 2, and on the coxa 2 there is a pair of big strong hooks. Look at picture three!. Can somebody (Nikita?) tell me the species. Greetings, Gerard Gerard Pennards attached the following image:  [81.15Kb] Edited by Gerard Pennards on 01-05-2009 19:57 Greetings, Gerard Pennards |

Hey Nikita, How are you doing? Hope everything is well. Busy with all the catches from your last trips? :-) Thanks very much for your answer, do you know the function of these interesting looking spines and hooks? Would you like to have the specimen? Greetings, Gerard Greetings, Gerard Pennards |

Hi Gerard. 1. Yes, a lot of questions and very few answers. On the other hand a very late spring in Russia this year, nothing to do till today, good spring to write articles. 2. Unknown (as 99% such questions in other cases). The rare case I know the function is described at: http://www.dipteradatabase.info/?article=11 hook-like spines on mid coxa present in scalaris, manicata-monilis, melania, atripes. Both hook-like spines on C2 and stright spines on katepisternum in lustrator, fuscula, vesparia. 3. I have only 1 male of lustrator, more material is very much wellcome!
