T iunatermes mariuzani gen. nov. et sp. nov., a new nasute termite from the B razilian savannah ( I soptera: T ermitidae)

T iunatermes mariuzani gen. nov. and sp. nov. from the subfamily Nasutitermitinae is described based on soldiers and workers collected in B razilian savannah ( C errado), J alapão region, B razil. Digital images, scanning electron micrographs and illustrations of diagnostic characters are provided. Soldiers and workers of T iunatermes share in particular some morphological traits with the neotropical nasute termite genera A nhangatermes   C onstantino, but soldiers can be distinguished by a conical nasus, procoxa without a hump on the anterior surface, abdominal sclerites well sclerotized, and imbricate tergites and workers are distinguished by mandible morphology, coiling gut in situ , and cuticular armature of the gizzard and the enteric valve.
