Sinclair, Bradley J., Brooks, Scott E. & Cumming, Jeffrey M., 2025, Revision of the western Nearctic species of Empis subgenus Enoplempis (Diptera: Empididae), Zootaxa 5615 (1), pp. 1-200 : 88

Empis (Enoplempis) geneatis species group

( Figs 12, 13 , 176–187 , 192 )

This group includes four species, E. (En.) fisheri sp. nov., E. (En.) geneatis (Melander) , E. (En.) oharai sp. nov. and E. (En.) subgeneatis sp. nov., which are distinguished by male head holoptic ( Fig. 176 ), unmodified male hindleg (e.g., Fig. 180 , except E. (En.) fisheri sp. nov., Fig. 178 ), long setae on scape, palpus and occiput (e.g., Fig. 181 , except E. (En.) fisheri sp. nov.), long acrostichal and dorsocentral setae (e.g., Fig. 180 ) and subepandrial process present (e.g., Fig. 186 ). In addition, males of this species group (unknown for E. (En.) subgeneatis sp. nov.) produce balloons ( Figs 12, 13 ).
