There are three myrmecophilous species in this genus. The genus Furcantenna is characterized by the combination of the following characters: wing vein R4+5 without posterior appendix; wing vein M1 straight, perpendicular to wing vein R4+5; abdomen broadly oval; antenna inserted below dorsal eye margin; basal antennal flagellomere much longer than scape, longer than distance between antennal socket and anterior oral margin; scutellum apicomedially sulcate; metasternum developed. There are 43 genera and more than 400 species in this Microdontinae subfamily of Syrphidae.
Based on morphology,Furcantenna nepalen-siswas recovered in a clade containing Carreramyia and Schizoceratomyia. Furcantennais is very similar to Schizocer-atomyiain both external morphology and male genitalia, but presently available evidence is not conclusive about the exact relationships between these taxa.
