Hypselosyrphus ulopodus

Diagnosis
This is the only known species of Hypselosyrphus with a pilose katepimeron and a ventrally widened occiput. Notes. This species is aberrant from its congenerics because of the pilose katepimeron, the ventrally widened occiput and the unproduced vertex (the latter character is only shared with H. pseudorhoga spec. nov.). A phylogenetic analysis based on morphological characters placed the species as a sister of the clade containing Rhoga and Hypselosyrphus (Reemer and Ståhls 2013 b). The relationships within this clade are considered not well enough established to introduce another generic name, hence the current assignment of this species.

Distribution
Neotropical: Peru, Paraguay
