Moved from Longlegged Flies.

Thanks John!
I got the same thing using the key you sent me.

18 to go
You still need to provide the missing 18(+/-) species not in the guide.

Sure I'll see what I can do. :)

Odd one
See subfamily page(1) for more recent generic limits.

Does the abdomen have black bands? Are there any ornaments on the tarsi, specifically rows of bristles? (For example, "fore basitarsus with a ventral brush of white hairs.") What is the ratio of the lengths of sections 1 and 2 of the fore tarsus? Is the hind trochanter black/green (vs. yellow)? Are the hairs on the bottom of the abdomen mostly pale or black? Does the face have white hairs (as in the caudatus group)? Does the shape of M1 and R5 look more like C. caudatus (broadly rounded curve), Amblypsilopus (sharper curve with R5 approaching M), or other Condylostylus (sharper curve in M1)? Does either the mid or hind femur have a preapical bristle?

Apparently the antennae are entirely black. Is the vertex sharply excavated? I can't see from this angle.

re Odd one
Yes the vertex is excavated, the angle is poor to see that but unfortunately it decided to cock its head to the side.

Antennae are completely black.

At a dorsal view, the abdominal segements have a black basal band.

The only possible tarsal modification is on foretarsus 2, which has an area of longer, slighly denser black setae as compared to those on other tarsi.

Segment of foretarsus is at least twice as long as segment two, maybe slightly more than twice as long.

Only the fore-trochanter is yellow. The middle and hind ones are black/green.

Setae on bottom of abdomen appear all pale.

There are white hairs on the face, laterally near the eye margin but not in the middle.

I don't see any strong bristles on the mid or hind femur.

I'll add a picture of the wing.
