Found today in the skylight behind my house, mid Netherlands. No idea?

Family Ceratopogonidae, tribe Ceratopogonini. Reminds me of Stilobezzia (Acanthohelea) but the American speies are more spiny. (The acantho- prefix means with thorns.) https://bugguide....iew/571364

Well, well, ... the specimen told another story. The last antennal segment bears a small apical nipple, placing it in Forcipomyiinae. Wing characters and the seta on the paratergite lead to Atrichopogon. The enormous genitalia lead to subgemnus Psammopogon and that means a species new to the Netherlands. Just downloaded the key but have no time today to finish the ID. Maybe tomorrow...?

Thanks Paul!!! Two new species in my garden for the Dutch fauna in one day. I'm curious what for Psammopogon it will be.

Atrichopogon (Psammopogon) actually. There appear to be two likely candidates considering the distribution of the subgenus but time will tell.

Atrichopogon looks good. I had not seen any Atrichopogon with large genitalia. In America we have a species of Stilobezzia with elongated genitalia.

Atrichopogon (Psammopogon) flavolineatus, based on the genitalia. As mentioned above, another species new to the Netherlands.

Interesting species Paul! Only known from Austria, Bulgaria ,Czech Republic , Slovakia and Spanish Mainland. Not really close to The Netherlands. Do you know something about its ecology?

Actually, it is also known from Germany (German checklist), Turkey, Greece, Hungary and Romania (World catalogue).
No info on biology (yet).

Jewell699, you should post it in the forum, not submit it for the gallery.

Jewelm699 - did you upload it to a forum (which one?) or the gallery? I can't find it.

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.

@Paul Beuk Thanks mate!! Best wishes!

Where are the meaning abbreviations of Lindner's series Die Fliegen der Palaearktischen Region, ie. f1: anterior femur, ...and what about "p"? (I don't possess volume I)

17.07.19 19:37
Yup, you can view the wing from above (dorsal side) and from beneath (ventral side).

Hey Dipterists! Quick Question: Vein r2+3 bare beneath. I've always assumed that this is below as in when you look at the wing flat. Am I right? Thank youuuuu! Pfft
