Fig. 10 in Species groups in the genus Cubitermes (Isoptera: Termitidae) defined on the basis of enteric valve morphology

Fig. 10. Gut coiling in soldiers and workers. A. Dorsal view; B. Ventral view. C = crop; D = diverticulum or caecum of the second paunch; Gz = Gizzard; M = mesenteron (dotted segment); MS = mixed segment; P1 to P5: first to fifth hind-gut segments (Holmgren 1909; Noirot 2001): P1 = ileum, P2 = enteric valve, P3 = paunch, P4 = colon, P5 = rectum. The gut is quite convoluted and some masked parts need to be described. In dorsal view, the distal end of the mesenteron (M) passes behind the upper loop of P3 to join P1 which is connected to P3 via P2; P3 turns forward, passes under the loops of M and P4 and finally turns left to join P4; P4 loops rightwards along M, then turns right and backwards behind M to join P5.
