This resembles a Dobson Fly, but the mouth parts are all wrong. What is it?

Moved from Antlions.

#50262 Identification -- Brachynemurus sackeni (male)
This is the antlion Brachynemurus sackeni Hagen, 1888. The strongly lyriform male abdominal appendages, while not unique to this species, are a good spot character to narrow down the possibilities.

Ant Lion
This looks like an adult Ant Lion. Family Myrmeleontidae.

Thanks, Jay
At least I was in the correct order. I have confirmed fron other pictures in the guide and elswhere. I have edited the title accordingly.


Great find
A great find. I've never noticed the "appendages" at the tip of the abdomen before.

You handled the white wall background well, too, those can be tricky.

The specimen is a male. Males tend to have longer abdomens (exceeding the tips of the folded wings in some genera), adorned with the bracket-like claspers. The morphology of the claspers is probably one way (maybe the ONLY way) to determine the species. Very nice image!
