21 and 22 October 2008, Lenkoran district, Burcali, on sap exudate of Quercus castaneifolia, 3 females and 2 males mounted. I would naturally suggest widespread (and still spreading) Z. indianus (quoted for the Palearctic Region together with Z. tuberculatus and Z. ghesquierei), but in the key by Chassagnard & Tsacas (Ann.Soc.Entomol.Fr. (N.S.), 1993, 29(2): 173-194) it evidently belongs to the same vittiger-subgroup but doesn't seem to have characters leading to indianus (frons without silvery median line, scutellum rather with a touch of white apically). In the original description (faulty as it is, according to Okada's marks), though, Gupta doesn't mention that silvery line at all. I decided to leave genitalia preparation for experts.

Identified as Zaprionus indianus by Dr. Vasily Sidorenko. |

There is a nice website about this fly and its distribution: http://www.kimvdlinde.com/professional/Zaprionus%20distribution.php Years ago I went collecting in Azerbaijan - absolutely awesome flies there, but the bureaucracy there is crazy..... Martin Hauser |

Many thanks for letting me know Martin. There's also a male collected in late October in Krasnodar Territory (Sochi/Adler) - I'm not sure whether Zaprionus is recorded from Russia. |

That single male from Adler is even more interesting (from tuberculatus group), let's wait for an expert opinion. |

I am actually going to remove the record. I had a second look at the images, and I am going to disagree with my colleague Sidorenko on the identification on the basis of the last image that shows that the composite spines are placed on tubercules, which places it in a different set of species excluding indianus. |

OK Kim, actually I had some doubts, too... Maybe I'll have a chance to show it to someone else... |

Ok, i stand corrected. Most of the individuals I had seen did not have tubercles, but it was pointed out to me that some do, and if they do, they form a series of tubercles that decrease in size from the body side towards the tip of the leg. So, I checked my collection more careful and came to the conclusion I have to retract my earlier assessment and will re-add the location to the map. |

The re-assessment re-assessed: a re-re-assessment.
