Photograph taken on 3 October 2015 in the wetlands of the Suárez Pond, Motril, Granada, Spain.
Immediate area of the Mediterranean coast.
Apparent size with wings, about 2,5-3 mm

Jordi Clavell, en "Biodiversidad Virtual", tells me I could be Zaprionus indianus

Thanks for help!

The images do not show the legs properly and that is necessary for species ID. Did you keep the specimen?

Hello Paul.
Will it serve the photo I attached to reach your ID?
The image is of 1800 dpi. Clicking on it is extended.

When it is no longer necessary to take more pictures, I will send you to your collection.

I have a curiosity. Are there many species of drosophila with those stripes so characteristic ?.

With the guidance of Jordi Clavell, I found these on the Web. I think the resemblance is striking.

Thank you always for your help.

The front femur appear to have the tubercles typical of indianus. I believe this is a species that is spreading through the Mediterranean area and elsewhere.

---

There are many similar species, but only Z. indianus is widespread outside of Africa. It has spread rapidly in North America recently. Two other species of even-striped Zaprionus are recorded from southern Europe in Fauna Europaea, one of which is much darker than your fly.

The leg characters Paul is looking for are illustrated here: http://zookeys.pe...hp?id=2231

Using the key to which John provides the link, Z. indianus seems to be the most probably candidate indeed.

Thanks for your help, Tony Irwin.
I understand that in your opinion if they match the characteristics of the front femur with Z. indianus. It's like that?
cordial greetings

John Carr, although I have no training or knowledge to know how to interpret the valuable information this URL, I've taken advantage: first to understand the wide variety of species of Drosophila, which may have white and black stripes on its top view.

And second, if I have been able to interpret well the link information, know the differences that allow to know the species that are referenced with the indicative a, b, c, d, e, f of Figure 2.
I proceeded to mount an image illustration f, which corresponds to Zaprionus indianus, cutting the femur with my photograph taken. Deputy well composed image. From my limited knowledge, I think we agree. But I would like to hear from you, the experts.

I am very grateful for your help and for the information you have given me to know.

Best wishes.
Jose Marin.

Thanks for your help and collaboration.
You made his entrance while I sent my reply to Tony and John, so I did not include earlier in my response.
In my opinion, you can rule out the similarity of the femur with the options a, b, c, d and e of Figure 2, according to the documentation link John Carr. And I think if it matches the option f, corresponding to Z. indianus
But I think it should be yourselves, the experts, who make the decision.

Best wishes from the south of Spain.

After examing the specimen I can confirm it is Z. indianus. :)

---

:D :D :D
Paul, very grateful for your help.
I think it's species that was not cited in Spain.

Best wishes from the south of Spain.

According to this site it is not, but here Spain and the Canary Islands are mentioned separately, so that makes one wonder... Unfortunately, the latter is just an abstract (I have no access tot he full report) and it may be the result of clumsy phrasing.

---

I have news that had been cited in Austria, Italy, and Madeira. So it is not the first European appointment.
Yes it is cited in Madeira, so it is not first appointment in Portugal. Madeira is part of the Portuguese State,
Yes it is cited in the Canary Islands, which is not first appointment in Spain. Canary is part of the Spanish state.
But if it would be first quoted in the Iberian Peninsula.
And, as recorded by CAB Direct, (not including Austria and Italy)would also be the first European appointment. Madeira and the Canary Islands are islands belonging to European states; but not part of the geographical continent of Europe.

---

I just met this link that Carles-Tolrá cited Z. indianus in Malaga, in 2009.
Comprising, already cited in Iberian Peninsula

Although no longer needed after Paul already confirmed it really is Z. indianus I hereby also confirm it :)

Jan Willen, you also am very grateful for your confirmation. ;)
