DESCRIPTION OF A NEW PLANICAPRITERMES FROM CENTRAL AMAZONIA, WITH NOTES ON THE MORPHOLOGY OF THE DIGESTIVE TUBE OF THE NEOCAPRITERMES-PLANICAPRITERMES GROUP (ISOPTERA, TERMITIDAE, TERMITINAE)

Planicapritermes longilabrum new species, is described from central Am azonia based on soldiers. The soldier of this new species is morpholog ically intermediate between Planicapritermes and Neocapritermes, but s hows several synapomorphies with P. planiceps. The gross morphology of the digestive tube of the soldier of the new species and of the worke rs of P. planiceps and four Neocapritermes spp. is described and compa red. The shape of the mixed segment of these two genera is distinctive , and provide a good diagnostic character to separate them.
