Hmm, could well be another genus. Have a larger image?

Paul, I wanted to sent reply as cf.Homoneura or 98%Homoneura, but afterwards I dicided that Homoneura is better for several reasons: 1. Really 98% in Oriental region 2. I collected a lot of Homoneura sp. looking exactly as this one 3. The answer Homoneura in Oriental region is almost equal to Lauxaniidae sp. Weiwei, to be sure, check fore femora, in apical 1/3 you have to find row of short black posteroventral spines clearly visible on yellow femora. If there are spines - Homoneura.

What about the costal spinules continuing till the apex of vein M1+2? That is the character we use to separate Homoneura from the other genera in Western Europe... Which they appear to do in the second picture, by the way, so I think Homoneura should be okay. And the posteroventral setae are visible in the second picture, too

The fly from Thailand was collected and verified both for f1 pv spines and costal spinules continuing till the apex of vein M1+2, as Homoneura. China fly looks rather similar enought to be from same genus, doesn't it? Nikita Vikhrev - Zool Museum of Moscow University |

Weiwei, to be sure, check fore femora, in apical 1/3 you have to find row of short black posteroventral spines clearly visible on yellow femora. If there are spines - Homoneura. I'm sorry, I wrote porteroventral instead of anteroventral. The setae on your image are not what we need. Anteroventral side, apical 1/3, very short and dence row.

This isn't a sure-fire way to identify Homoneura (at least as far as I know) as a genus. Some Meiosimyza (ie. rorida in Europe) have such spinules. I still agree with Nikita, it's most probably a Homoneura. Kahis |
