Good day fly lovers and friends,
a strange looking Suillia from Madeira collected inon 19-3-1989 at 500-60m altitude.
Of course, again, the photo`s are bad, but nevertheless...
At first I thought about S. oceana, but it is not. The tergits are very glossy blackish/very dark brown. Mesopleura is hairy, arista very long plumose like a variegata. The end half of the palpi is blackish...
All tibiae have extremely long hairs ventrally, much longer than the femurs are thick. Also the tergits of the abdomen are covered with long hairs.
I would like to know which species it is.

Very well possible is is S innotata. I will check it later this week. A very peculiar animal!
Thanks!

I don't know why you would think this is not
oceana - it is exactly like the
oceana material I have (and this is what it should look like)

I checked it with the description of Czerny. I believe that the descriptions and this specimen do not fit. The fly is in my study, I am enjoying my breakfast now, so am unable to tell you exactly where they differ, I will do later this evening or perhaps tomorrow, but I remember that Czerny mentions several brown spots on the thorax. I can't find them back on this animal. And so there are some more

If you take the key of Czerny of the Suillia's in the Fliegen of the Pal. Region on page 7 at point 5 you see that Czerny says that the palpi of innotata are yellow. If you go to the description of S. innotata on page 15 you read:"Taster an der Spitzenhaelfte schwarz"! I think there is a mistake in the key.
Looking at the specimen from Madeira and using the full description of the species in Czerny I think it is rather innotata than oceana, though the abdomen is quite glossy as mentioned for oceana.
In the description of S. oceana so many different spots on the head and thorax are mentioned. If there are some spots on the specimen they are so weak. S. innotata fits perfectly. Question, maybe a barbarian one, aren't innotata and oceana some the same species????
