Specimens with one or more of the following: eyes and wings well-developed, and/or (if eyes or wings reduced) with metatrochanters bearing some form of hook; often also with weak to prominent metaventral process (males) .......... 2 1′. Specimens, if small-eyed, then without modified metaventrite or metatrochanters (females) ....................................... (not keyed further) 2. Eye well-developed, comprising more than 6 ommatidia............................................... 2b 2′. Eye extremely reduced, with fewer than 5 ommatidia................................................... ...... 6 (in Caterino and VÁsQuez-VÉlez 2017 ) Figs. 1–3. Phylogenetic hypotheses for Prespelea species. 1 ) Maximum likelihood tree based on COI data alone; 2) Parsimony tree based on morphology alone (40 steps; CI = 0.525, RI = 0.678); 3) Parsimony tree based on combined morphology and COI data (values shown above branches represent majority rule consensus indices; numbers next to names are DNA extract numbers in Caterino collection or [JP] Joseph Parker collection). 2b. Eye fully developed, with>20 ommatidia, winged (humeri wider than prothorax)........... ...... 3 (in Caterino and VÁsQuez-VÉlez 2017 ) 2b′. Eye reduced, with <10 ommatidia ( Fig. 4 ); not fully winged, humeri narrowed to prothorax ................... P. videns , new species
