RESUMO

This is the taxonomic revision of the South American genus Spinitermes Wasmann, 1897 (Isoptera, Termitidae, Termitinae). I studied 399 samples including all those from MZUSP and others from institutions that I requested material as loans. The species of this genus feed on decomposed organic matter and occurs in both the soil and in the epigeal nests constructed, mainly, by species of the genus Cornitermes (Termitidae, Syntermitinae). Using morphological characters, mainly from soldiers, I clustered the six species already known and the three new ones into three groups: Grupo allognathus: Spinitermes allognathus, S. sp. A, new species and S. sp. B, n.sp.; Grupo robustus: S. robustus; and Grupo trispinosus, that I subdivided, accordantly to the enteric valves characteristics, into two subgroups: Subgrupo de V.E. lisa: S. longiceps, S. nigrostomus, S. trispinosus and S. sp. C, n.sp., and Subgrupo de V.E. rugosa: S. brevicornutus. I described all castes of the three groups and made diagnoses for the species and subgroups; I also made illustrations of the soldier and imago, when presents, for all species and the pronote, mandibles, galea, lacinia, digestive tube in situ, enteric valve and crop from workers of the three groups. In addition, I present a dicotomic key for identification of the species using soldiers and geographic distributions maps for all species.
