Transfer of two species from N asutitermes D udley to C ortaritermes M athews ( I soptera: T ermitidae: N asutitermitinae)

Soldiers and workers of the N eotropical nasute genus C ortaritermes are easily differentiated from other nasutitermitine genera by the first proctodeal segment of the coiling gut in situ forming a distinct loop visible throughout the abdominal wall on the right side of the abdomen. The study proposes to transfer two species currently in N asutitermes to C ortaritermes , raising the total number of C ortaritermes species to five: C . silvestrii ( H olmgren, 1910) (type species), C . fulviceps ( S ilvestri, 1901), C . rizzinii ( A raujo, 1971), C . intermedius ( B anks, 1919) comb. nov. and C . piliceps ( H olmgren, 1910) comb. nov. The last two species, C . intermedius and C . piliceps , are herein redescribed, and digital images are provided. The distribution of C ortaritermes is now expanded to northern and north‐eastern S outh A merica.
