but don't see the image in the post.
Indeed, using the key on pg. 243 of Curran[1941] (PDF here), this cerioidine goes to Cerioides vittipes via the couplet sequence:
8) "Antennal process at least as long as the first antennal segment" ;
9) "Second abdominal segment strongly constricted" ;
10) "Abdomen reddish" ;
11) "First abdominal segment yellowish the basal half or more" (and this is not tricolor!) ;
12) "Dark markings of the head and thorax black"......vittipes
Your photos of this male from Peru are also in excellent agreement with the original description of the male of Cerioides vittipes from Peru on pg. 246 of Curran[1941].
Note also that Cerioides vittipes is now a prior synonym for Monoceromyia vittipes, per the 1976 catalog of Thompson et al. See also this Picture Key to the genera of Syrphidae from the Brazilian Amazon...which leads to Monoceromyia here, and lists M. vittipes in the region.
Your photos form an excellent reference post for this distinctive and very beautiful cerioidine!
