apex, discal cell small, no longer than the equal basals, anal cell short, the crossvein abruptly reflexed 
and fusing with the under side ofthe anal cell, the anal vein faint but almost complete, alula distinct

Type species : L. chichimeca, Wheeler & Melander (Pl. 2, Fig. 13), so designated by 
Coquillett in 1903.  Lamprempis was first proposed as a subgenus of Empis, but the species are so. 
highly specialized and distinctive that the group deserves generic rank. Bezzi(1909) has given a table - 
of the known species, all of which are restricted to tropical and subtropical America.
