Key to the soldiers of Rhynchotermes 

1 Mandibles larger than head, clearly visible from dorsal view when closed; apical region of each mandible extending well beyond the opposite mandible when closed ( Fig. 6View FIGURE 6 B)........................................................ 2

- Mandibles shorter than head capsule, barely or not visible from dorsal view when closed; apical region of each mandible aligns to the proximal region of the opposite mandible when closed ( Fig. 6View FIGURE 6 A)........................................... 3

2 Proximal region of frontal tube constricted; apical region bulbous ( Fig. 3View FIGURE 3 C, 4 C)......................... R. bulbinasus 

- Frontal tube elongate, subcylindrical ( Fig. 3View FIGURE 3 H, 4 H)................................................ R. perarmatus 

3 Mandibles with inner margin serrated, strongly curved ( Fig. 5View FIGURE 5 A, F, G, I).......................................... 4

- Mandibles with inner margin smooth, evenly curved ( Fig. 5View FIGURE 5 B, D, E)............................................ 7

4 In profile, dorsal margin of head and margin of frontal tube almost straight ( Fig. 4View FIGURE 4 F, I).............................. 5

- In profile, dorsal margin of head and margin of frontal tube markedly concave ( Fig. 4View FIGURE 4 A, B, D, E, G).................... 6

5 Length of frontal tube equal or slightly longer than length of head (see setae Fig. 4View FIGURE 4 I); head capsule without frontal tube wider than longer ( Fig. 3View FIGURE 3 I)............................................................................. R. piauy 

- Length of frontal tube much longer than length of head (see setae, Fig. 4View FIGURE 4 F); width and height of head capsule without frontal tube approximately equal ( Fig. 3View FIGURE 3 F)........................................................ R. matraga  sp. nov.

6 Head with a slightly constriction behind antennae, antennae articles long ( Fig. 3View FIGURE 3 A, 4 A, 5 A)...................................................................................................... R. amazonensis  sp. nov. ( major  )

- Head capsule rounded in dorsal view, antenna articles short ( Fig. 3View FIGURE 3 G, 4 G, 5 G,)........................ R. nasutissimus 

7 Length of frontal tube equal to length of head ( Fig. 3View FIGURE 3 D, 4 D, 5 D).................................. R. diphyes  ( major  )

- Length of frontal tube distinctly longer than head........................................................... 8

8 Frontal tube conical, mandible thin, four bristles on head ( Fig. 3View FIGURE 3 B, 4 B, 5 B).............. R. amazonensis  sp. nov. (minor)

- Frontal tube subcylindrical, oriented downwards, six to ten bristles on head ( Fig. 3View FIGURE 3 E, 4 E, 5 E)........... R. diphyes  (minor)
