Collected end of August 2011 in Portugal in the vicinity of Porto. I think this may be Leptogaster cylindrica, am i right? According to Fauna Europaea however the genus Leptogaster is not known from Portugal, which makes me hesitant. Thanks in advance Auratus attached the following image:  [144.24Kb] Edited by Auratus on 09-02-2012 22:18 Greetings, Jan |

I think it is another species because of the shape of the hind tibia. Can you place pictures of wings, thorax and genitalia?

Hello Reinoud, Thanks for watching. I have added pictures of wing and legs, hope it is sufficient. Clear picture of the genitals are a bit more difficult to produce. See what i can do in the evening. Auratus attached the following image:  [153.44Kb] Greetings, Jan |

Shape of genital is different from cylindrica as is shape of hind tibia. In key of EO Engel step 1. asks pterostigma..... To me it looks as if this wing has a pterostigma but i have no experience with exotic Leptogasters. but if it is really a stigma then.....I am not at home at this moment so it might take some time before i react next time.

Although i still think that the hind tibia are strangly shaped, it probably is L. cf cylindrica hispanica..... It seems that there is little known about the Asilidae in Portugal. I think we might assume that they will have a lot in common with Spain.

Hello Reinoud, Thats exactly the problem, the lack of available literature. I just have some literature of the Dutch species, which is of course absolutely insufficient. Unfortunately i also do not have the key by Engel you are referring to. And i thought this would be the easy one, because i have some other species from that region as well I appriciate the effort you have put in it untill now. Here are the pictures you requested, hope ther is sufficient detail on them. Auratus attached the following image:  [182.14Kb] Greetings, Jan |

Sorry Jan, You are right in your presumption. Key by Engel mentions species that are no longer accepted according to Fauna Europaea. My key became useless despite your pictures. I just don't know... : ( Greetings, Reinoud Field guide to the robber flies of the Netherlands and Belgium: https://www.jeugdbondsuitgeverij.nl/product/field-guide-to-the-robberflies-of-the-netherlands-and-belgium/ https://www.nev.nl/diptera/ |

Oke Reinoud, Thanks for all your efforts. I will keep it as Leptogaster cf cylindrica hispanica. Greetings, Jan |

Addendum: Used key by Seguy now and. The bristles on the back of the head seem black according to key by Seguy i end up with L. hispanica. This is however no longer a valid species. Wing venation supports L. cylindrica. Maybe if we put one and one together.... Remains a cf i'm afraid. Until i find a recent key..

Reinoud, when you find a key, as stated before, please let me know. I have more Portugese Asilids waiting for a name FYI, I have checked it and the bristles on the back of the head are black. Edited by Auratus on 08-03-2012 18:18 Greetings, Jan |
