A new user (Encarnacion Quijada) has taken a pic to another fly like that in the same province

Cut from here http://www.biodiv..._id=297663

- Tarragona (E. Spain)

Any help is welcome, thanks :)

I see in the gallery Anthomyia bisetosa, but i thought Anthomyia illocata (Walker) mostly Oriental species, also has no black spots before suture.
Maybe Ackland will have a look at this one ( and the one in your other thread)

This looks like Anthomyia illocata in general appearance. I can't of course see any small critical characters such as arista, setae on proepisternum etc.

If it is A. illocata, then it is a new introduction to Spain. If it is just a fortuitous specimen off a plane, then it will not be possible to catch more material. Being a female there is a chance of it breeding and forming a population.

This species seems to be spreading. Usually it is considered an oriental species. I have seen evidence that it occurs in southern North America, but not recorded from there. The other possibility (and perhaps a more likely one) is that it is Anthomyia amoena Macq. which is an A|frican species, which has longer setae on arista.

What is needed is some male specimens from Spain, and if any are sent to me I will investigate further.

I am quoting this from memory. I will check up on the details later, and come back with more information.

I recently offered a specific name to a photo of a Fucellia species on seaweed from America. No one has picked this up, but it could go in the gallery. I can't give the link as I will lose this reply, but I will bring it to the fore by adding another reply.

An introduction would explain some puzzling pictures I have seen on BugGuide. They appear to be members of the Anthomyia pluvialis group, but do not match any species in Griffith's key. (http://bugguide.n...45/bgimage) How can A. illocata be distinguished from other black and white Anthomyia?

Edit: I found Sasa's 1987 paper so I see how to distinguish A. illocata from east palaearctic Anthomyia, and Griffiths' revision will distinguish nearctic species. I don't know about any other world species.
