3 mm. Taken today in Motril (Granada).

Similar to this Odinia ornata of Dmitry Gavryushin: http://www.diptera.info/photogallery.php?photo_id=2174

Thanks

The basal anteannal joint on your fly are yellow - so not ornata so possbly something close to xanthocera ?

One normally needs to inspect genitalia on Odinia, so ID from a photo alone is difficult

I'm not a specialist but I don't think this is odinia. I remember that I found a similar one last year. http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=37964

Also here, there is no presutural dorsocentral which makes this Neoalticomerus. Then you have to look to genitalia and hope Phil has a look at it. ;)

Again on your Neoalticomerus the basal antenatal joints are black. not yellow as pictured in Manuel 's photo.

Best wait for Phil

Here is the key to separate the two genera (Bei Bienko) :

1 (2). Mpl. bare, without br. or hairs. Msn. with five pairs of dc.
pvt long and well developed. t without subapical
br. ................................................... . . l . Odinia R.-D
2 (1). Mpl. with setae, along post. margin with two well developed
br. Msn. with four pairs of dc. pvt short and weak.
t with subapical br .............. 2. Neoalticomerus Hendel.

As far as I can see, there are 5 dc, no setae on anepisternum, so this one is Odinia.

This is an Odinia - the light coloured antennae would lead immediately to xanthocera...if it were not for the fact that there are at least two taxa with this condition (one with fat hind femora, the other without)...for now (unless you caught this) it's a "near xanthocera".

Thanks Phil and Sthephane for the information. Again something learned. Next time I go in the books before I react. |t

:) my first guess was "something close to xanthocera"

I usually struggle with Odinia !

The only 'all together now' I know is "all you need is love". But I guess everyone loves Odiniidae. :D

Interesting debate, pity that I was late, but here always be on time to the party. I came here reviewing a specimen in alcohol than I would have sworn it was O.ornata. Then I've seen this discussion and decided to stop the car. To my knowledge, we have only one genus reported from the Iberian Peninsula, Odinia, with 5 species and xanthocera is not among them.
Phil, what is the other species with the the light coloured antennae?
