I was going to make a guide page for this, but Borror, Triplehorn and Johnson (1) state that the members of this family are "rather brightly colored with pale markings on blackish background." This doesn't seem to be the case with this specimen, which looks entirely orange. As well, that book gives a character of cell M3 being closed in this family - its hard to make out, but it doesn't look closed to me. You seemed to be somewhat hesitant on this one - are you confident about the family, or could this be something else?

Further investigation leads me to believe you are right and that this is a species of the Xylophagidae. When you look at http://www.faunistik.net/DETINVERT/XYLOPHAGIDAE/xylophagidae.html you will see an image of Dialysis that resembles this specimen quite well.

Sounds good Paul. I'll move it to a family page. The link you included is missing a piece though; it should be http://www.faunistik.net/DETINVERT/DIPTERA/XYLOPHAGIDAE/xylophagidae.html instead.

I typed in the link rather than copy-paste it. That is what you get when working on two computers at the same time. Thanks for putting in the right link. ;-)
