I am currently working with the key of the genera of the flower flies
of the Neotropical region (1999), on a investigation project of the
colombian syrphidae, and I have a question on the 55 item:
1. Is the 55 item provenient of the sixth item?
2. Does the 55 item refers to the 58 item?

I would really apreciatte all your help and comments
