Key to the genera of the subfamily Itaquasconinae 

1. Pharyngeal bulb with only one undivided placoid or no placoids ................................................................................ 2 More than one placoid present*.................................................................................................................................... 4

(*) We do not consider the simplex stadium or pseudosimplex stadium.

2. Caudal tract of the bucco-pharyngeal tube rigid, without spiral thickening ( Fig. 19View FIGURE 19 A) .................................. Parascon 

- Caudal tract of the bucco-pharyngeal tube flexible with a spiral thickening ............................................................... 3

3. Rigid buccal tube longer than the apophyses for the insertion of the stylet muscles; stylet supports present ( Fig. 19View FIGURE 19 E) ..................................................................................................................................................................... Itaquascon 

- Rigid buccal tube very short (as long as the apophyses for the insertion of the stylet muscles); stylet supports absent ( Fig. 19View FIGURE 19 F) ...................................................................................................................................................... Astatumen 

4. Caudal processes of the apophyses for the insertion of the stylet muscles point backwards and sideways ( Fig. 19View FIGURE 19 B). Branches of the stylet furcae of the Mesocrista  type ( Figs. 4View FIGURE 4 E, 19 C) .......................................................... Mesocrista 

- Caudal processes of the apophyses for the insertion of the stylet muscles point sideways ( Fig. 19View FIGURE 19 D). Branches of the stylet furcae of the Platicrista  type ( Fig. 4View FIGURE 4 F)............................................................................................... Platicrista
