Amitermes beaumonti Banks, 1918
Soldier ( Figs. 15A, 15B View FIGURE 15 ): Described by Banks (1918), with a redescription by Light (1932). Additional illustrations are provided here.
Gut anatomy ( Figs. 6C View FIGURE 6 , 7D, 7E View FIGURE 7 , 16A View FIGURE 16 , 17 View FIGURE 17 , 18A View FIGURE 18 ): Crop slightly asymmetrical, covered internally with pectinate scales before gizzard. Gizzard of the generalized type, with columnar and pulvillar belts subequal in length; firstorder pulvilli conspicuous, with tiny pectinate scales, second-order pulvilli reduced ( Fig. 16A View FIGURE 16 ). Stomodeal valve inserted in apex of mesenteron. Mesenteric tongue internal to mesenteric arch, filiform proximally and gradually enlarging to tip, ending above dilated portion of first proctodeal segment (P1) and enlarged distally ( Figs. 17 View FIGURE 17 A–17C). P1 fusiform, crossing abdomen diagonally in dorsal view, over paunch (P3), inserted in P3 dorsally at right side of abdomen, but partially occluded by P4 segment ( Fig. 17E View FIGURE 17 , arrow). P1 cuticular ornamentation composed of sparse small spines around mesenteric tongue at mixed segment, followed by elongated area of spines ( Figs. 6C View FIGURE 6 , 7D View FIGURE 7 ), and sparse spines in distal portion, just before enteric valve ( Figs. 6C View FIGURE 6 , 7E View FIGURE 7 ). Enteric-valve armature (P2) composed of six digitiform cushions ornamented with small spines distally, and with broadly coverage of small spines proximally ( Fig. 18A View FIGURE 18 ). P3 well developed and globose, with a marked pouch after P2 ( Figs. 17A, 17B View FIGURE 17 , arrows). Isthmus easily recognizable. Fourth proctodeal segment (P4) with short U-turn and located dorsally ( Fig. 17A View FIGURE 17 ).
Comments. Although the available specimens for this study are from Panamá ( Fig. 14 View FIGURE 14 ), we agree with one of the reviews suggestions and include in the paper, since this species distribution overlaps with A. foreli , and maybe reachs the west of Colombia.

Amitermes foreli Wasmann, 1902
Soldier ( Figs. 15E, 15F View FIGURE 15 ,): originally described by Wasmann (1902), with a brief description of the external morphology of the soldier, worker and nymph. A good redescription was provided by Light (1932), based on the type specimens. Additional illustrations are provided here.

Gizzard of the generalized type, with columnar and pulvillar belts subequal in length; first-order pulvilli conspicuous, with tiny pectinate scales, second-order pulvilli reduced ( Fig. 20B View FIGURE 20 ). Stomodeal valve inserted in apex of mesenteron. Mesenteric tongue internal to mesenteric arch, narrower proximally and gradually enlarging to tip, ending before dilated portion of first proctodeal segment (P1) ( Fig. 25C View FIGURE 25 ).

Comment. Only a few specimens were available to prepare the enteric valve slides and we did not succeed in obtaining a perfect preparation; however, the original description includes pictures.
