In 14th September 2008 I and Andrade went to the Apulia beach. We had a very pleasant day - clear sky, with 20 km/h winds. We explored the sand dunes all the day, trying to have a clear perspective of the local diptera fauna. We did happen to see some amazing flies. Therefore: We found some Tethina and the resulting video of Tethina pictipennis is probably the first in Europe to be made - http://www.youtub...orr43GJsXQ This is only 3 mm to 4 mm in length. Tethina pictipennis Freidberg and Beschovski, 1996. Hitherto ONLY known from Morocco is therefore a new species for Europe. And we must acknowledge Rui Andrade for this fantastic discovery! Concerning T. pictipennis, the pictures show well the presence of ocellar bristles( 2 proclinate), the post-ocular bristles are converging and it has 3 pairs of frontal bristles. In one photo (from the profile ones), the vibrissae-like bristles can barely be visible. Wings are unmarked except for the central circular and black dots. I have seen some with 2 spots - maybe a local variation (as we can see variations among humans), vein subcosta running parallel to R1 vein and then merging with it before reaching the costa. It is amazing to see a fly with almost no bristles on pleura!  This Tethina pictipennis is among one of the most beautiful flies in Europe, undoubtedly and a paper about the subject is expected to be out soon, having the collaboration of Munari, me and Andrade concerning this new fly. Tethina illota is smaller, with more striking legs than T. pictipennis, much more bristly scutum comparing with T. pictipennis and locally it isn't as common as T. pictipennis, at least in the 2 day survey. And the photos... (4:1 magnification to 2:1 magnification) EDIT: This is a new species for Science and it is a Tethina lusitanica in Canacidae family. jorgemotalmeida attached the following image:  [193.05Kb] Edited by Paul Beuk on 17-02-2009 10:01 |

Thanks, St?phane. Really this is a nice find made by Andrade and then documented by myself and Andrade. I must inform that Tethinidae is no more accepted as a family. Now McAlpine, 2007 defends "the family concepts Canacidae and Tethinidae are here combined as a single family, the former (as Canacenae Jones, 1906) having nomenclatural priority over the latter(..)" So this is a fantastic canacid from Apulia. With great landscapes as I will show later.
