Key to the identification of Cretaceous Microphorites

1. Eyes occupying most of the head. Basal flagellomere abruptily tapered, with base bulbous ...................... ................................................................................................................ M. oculeus Grimaldi & Cumming

–. Eyes normal sized. Basal flagellomere shorter............................................................................................2

2. Wing vein C ending at R4+5 ....................................................................... M. similis Grimaldi & Cumming

–. Wing vein C ending beyond R4+5.................................................................................................................3

3. Antennal arista short, as long as basal flagellomere. Vein R2+3 clearly shorter than R4+5 .............................. ..................................................................................................................... M. utrillensis Peñalver sp. nov.

–. Antennal arista long, around twice basal flagellomere. Vein R2+3 barely shorter than R4+5.........................4

4. Four strong setae on the scutellum ............................................................................... M. extinctus Hennig
