Key to Neotropical subfamilies of Miridae

1 Tarsi two segmented, the first segment shorter than the second; ocelli present............................ Isometopinae

- Tarsi two or three segmented; ocelli absent................................................................. 2

2 Parempodia large, fleshy, apically convergent or divergent, arising between claws; phallotheca never cone shaped........ 3

- Parempodia setiform, if large, fleshy, and convergent, then with a cone-shaped phallotheca nested within the left paramere and protruding posteriorly from genital capsule................................................................ 4

3 Parempodia divergent at apices, usually thickened; a prominent collar present, separated from anterior margin of pronotum by a deep furrow.................................................................................. Mirinae *

- Parempodia convergent at apices, usually slender; pronotal collar absent, if present, not separated from pronotum by a deep furrow................................................................................... Orthotylinae *

4 Pulvilli present, free, or connected along inner surface of claws, sometimes difficult to see, in which case a collar is always absent.............................................................................................. 5

- Pulvilli absent; collar present or absent..................................................................... 6

5 Pulvilli arising from base or inner margin of claw; hemelytral membrane with.................. two cells; tarsi uniformly slender....................................................................................... Phylinae *

- Pulvilli arising from ventral surface of claw; hemelytral membrane with one or two cells; tarsi thickened distally or slender with tiny pretarsi............................................................................... Bryocorinae *

6 Claws distinctly toothed or thickened at bases; never toothed apically............................... Deraeocorinae *

- Claws not toothed or thickened basally; apex almost always with a fine subapical tooth ..................... .. Cylapinae *
