Notes on Eucryptotermes with a new species from central Amazonia (Isoptera: Kalotermitidae)

Eucryptotermes breviceps, new species, is described from central Amazonia. Both imagoes and soldiers of this new species have only two apical spurs on the foretibia, a condition previously unknown for Kalotermitidae. The soldier of E. breviceps has a peculiar and extremely phragmotic head. The geographical distribution of E. wheeleri is expanded with new records, and measurements of soldiers and imagoes of this species are presented for the first time. E. wheeleri is a native of the Atlantic forest of southeastern Brazil, from Santa Catarina to Rio de Janeiro, but it has been recorded in urban areas and may be an occasional minor pest.
