Key to genera of aquatic larvae of Nearctic Hemerodromiinae

1 Terminal abdominal segment ending in a pair of prominent, divided apical lobes; terminal pair of prolegs at least 2 x longer than preceding 6 pairs ( Figs. 1 View FIGURES 1 – 4 a, 1b) ............................................................................ Hemerodromia Meigen View in CoL

- Terminal abdominal segment lacking apical lobes; terminal pair of prolegs 1.5– 2 x longer than preceding 4 pairs (anterior 2 pairs may be shorter yet) ( Figs. 2–4 View FIGURES 1 – 4 ) ......................................................................................................... 2

2 Body robust, prolegs long and robust ( Fig. 2 View FIGURES 1 – 4 a), crochets prominent relative to couplet 2- below (see description for actual measurements and ratios); terminal abdominal segment ending in two very small, but distinctly separated processes, each of which bears a pair of setae ( Fig. 2 View FIGURES 1 – 4 b) ................................................................... Neoplasta Coquillett View in CoL

- Body slender, prolegs short and slender ( Figs. 3 View FIGURES 1 – 4 a, 4a), crochets less prominent relative to couplet 2 above (see description for actual measurements and ratios); terminal abdominal segment ending in two pairs of setae that do not arise from distinctly divided processes ( Fig. 3 View FIGURES 1 – 4 b, 4b) .................................................................................................... 3

3 Setae on terminal abdominal segment and longitudinal cuticular striations strongly developed relative to couplet 3- below (see diagnosis section for explanation and interpretation) ( Fig. 3 View FIGURES 1 – 4 a) ................................... Chelifera Macquart View in CoL

- Setae on terminal abdominal segment and longitudinal cuticular striations weakly developed relative to couplet 3 above (see diagnosis section for explanation and interpretation) ( Fig. 4 View FIGURES 1 – 4 a) ................................ Metachela Coquillett View in CoL
