A member of a macro photography forum posted this fly as an example of stacking and I asked her if I could post it up here for him so someone could ID it. He gave me the green light so here goes.

Thanks, will pass on the info.
I'm a little confused by the cf reference, as that is used to denote that a species is similar to another species but not yet confirmed as being related.
Are you therefore saying that Hylemya vagans is similar to Hylemya nigrimana but that the two are not yet confirmed as being related?

means "close to, but cannot be certain from features present in photo" - or something like that.

Could be either H. vagans or H. nigrimana, but both not certain ;).

Well the actual meaning is in this statement on the Wikipedia:

"In the system of binomial nomenclature cf. is used to indicate that the species needs to be seen in context of its comparison to another, but by definition is not confirmed as the same. For example, Corvus cf. splendens indicates "a bird similar to the House Crow but not certainly identified as this species"

Also from a Tarantula forum:
"cf." is used when the identification is not confirmed, but the organism appears similar to or is thought to be a particular species"

"sp." is used when the species has not been determined, even often by sheer guesswork
