Hi to all This is a very special record I will share with you. In last month Emídio Machado was photographing salticid spiders in Castelo Branco and took one specimen to Ricardo Silva, expert on spiders. Silva has realized that the Evarcha sp (juvenile Salticidae) was parasited by something. It pupated along within two weeks and emerged from the pupa this Monday - 2009 September, 07. The spider that was parasited is precisely this individual: http://www.pbase....cha_sp_x35 My friend Silva sent to me the acrocerid. And a very special thing: the puparium where the acrocerid came out! It is a rare sight. Immediately the genus was easy to recognize with the location of the antennae... Also due the wing venation and general form of the body - Ogcodes. Then I contacted the Christian Kehlmaier and Theo Zeegers. Both had some of mine ideas (I was hesitating between 3 species) and it is general consensus that this can be an Ogcodes cf. pallipes. But it is hard to know because the European Ogcodes is in a mess at the moment. It is necessary much more fresh specimens from all the Europe to make molecular studies so we can tell with more certainty which species it could be. EDIT: Dr. Emilia told me that this can be a probable Ogcodes cf. obscuripes jorgemotalmeida attached the following image:  [186.14Kb] Edited by jorgemotalmeida on 06-02-2012 14:26 |

We must start to collect salticids |

The taxonomy of Ogcodes is rather obscure at the moment. But a revision of the westpalaearctic fauna (to start with) would be an excellent PhD project. It has everything: morphology, molecules, ecology, lots of field-work and rearing in the lab. So anyone who is looking for a suitable topic, take up the challenge and tackle Ogcodes! I am sure that we would all be willing to chip in the few specimens we have in our collections. Christian |

I'm very surpried to hear a thomisid being parasited by acrocerids. I thought it would be more easy in lycosids and salticids. The Diaea dorsata is very common right now in Buçaco mountain. Maybe I will try this... but I never saw an acrocerid in Buçaco. |

Well, recently I got the results from Kehlmaier on this acrocerid. I sent it to Kehlmaier for barcoding and this is an Ogcodes reginae. He wrote: "I received the barcodes for all specimens. Both Ogcodes (the one from Helene Dumas and the one from Portugal) most probably belong to the same species (their genetic difference is less than 1%). I would say they are O. reginae. " Helene Dumas photos of Ogcodes reginae --> http://www.dipter...d_id=40070 Thanks to Kehlmaier and Helena that helped a lot to clarify better the acrocerids.
