Lyneborgimyia magnifica Doczkal & Pape  

Distinct from all other known Syrphidae by the presence of at least the following four unique autapomorphies: an additional, complete cross-vein between R4+5 and M1; trochanteral process of the mesocoxite (coxal prong) shortened; posteroventral part of epimeron not sunk, together with anterior part of katatergite forming a unified flat surface; anterior corners of sternite 1 broadly fused with the metaepimeron. Differing from all other Eumerini by the following two character states: katepisternum completely without setae; hamus missing. [The ‘hamus’ is a hook-like paired structure attached to the base of the phallus and the interior wall of the hypandrium (Doczkal, 1996), and a characteristic feature of the male terminalia of Eumerini.]
