Key to genera of aquatic pupae of Nearctic Hemerodromiinae

1 Four bristle-like apical spines on terminal abdominal segment, 2 projecting dorsolaterally and 2 projecting ventrolaterally; femur of fore leg (visible through the pupal cuticle) thin, subequal in width to femur of middle and hind leg ( Fig. 5 View FIGURES 5 – 6 ) .......................................................................................................................................... Neoplasta Coquillett View in CoL

- Two bristle-like apical spines on terminal abdominal segment, each projecting either posteroventrally or posterolaterally; femur of fore leg thick, width 2 x that of femur of middle and hind leg ( Figs. 6–8 View FIGURES 5 – 6 View FIGURES 7 – 8 ) ....................................... 2

2 Two bristle-like apical spines on terminal abdominal segment projecting posteroventrally; pre-terminal abdominal segments with posterior row of several large spines; dorsal spines of terminal abdominal segment ca. 1/2 length of bristle-like apical spines ( Fig. 6 View FIGURES 5 – 6 ).............................................................................................. Hemerodromia Meigen View in CoL

- Two bristle-like apical spines on terminal abdominal segment projecting posterolaterally; pre-terminal abdominal segments with posterior row of numerous small spines; dorsal spines of terminal abdominal segment no more than 1/ 5 length of bristle-like apical spines ( Figs. 7–8 View FIGURES 7 – 8 )........................................................................................................... 3

3 Pre-terminal abdominal segments with posterior row of spines of nearly alternating longer and shorter lengths ( Fig. 7 View FIGURES 7 – 8 ); dorsal spines of terminal abdominal segment ca. 1/5 length of bristle-like apical spines (tend to get broken or dislodged on specimens in alcohol vials) .......................................................................................... Chelifera Macquart View in CoL

- Pre-terminal abdominal segments with posterior row of short spines of uniform length ( Fig. 8 View FIGURES 7 – 8 ); dorsal spines of terminal abdominal segment ca. 1/10 length of bristle-like apical spines ....................................... Metachela Coquillett View in CoL
