Taxonomic Note

Ageniella fulgifrons is part of the 'accepta group' as defined by Townes (1957), which includes at least three North American species: A. accepta, A. conflicta, and A. blaisdelli. The scarcity of published information on A. fulgifrons specifically suggests that many records may exist under related species names or await modern revision.
