| Chamaecrista belongs to subtribe Cassiinae (Caesalpinioideae), and it comprises over 330 species, divided into six sections. The section Xerocalyx has been subjected to a profound taxonomic shuffling over the years. Therefore, we conducted a phylogenetic analysis using a cpDNA trnE-trnT intergenic spacer and nrDNA ITS/5.8S sequences from Cassiinae taxa, in an attempt to elucidate the relationships within this section from Chamaecrista. The tree topology was congruent between the two data sets studied in which the monophyly of the genus Chamaecrista was strongly supported. Our analyses reinforce that new sectional boundaries must be defined in the Chamaecrista genus, especially the inclusion of sections Caliciopsis and Xerocalyx in sect. Chamaecrista,... |

| The four new species Sennius bruneus sp. nov., S. kingsolveri sp. nov., S. maculatus sp. nov. and S. niger sp. nov., predators of seeds of Chamaecrista Moench (Caesalpinaceae) from Serra do Cipó, Santana doRiacho, Minas Gerais, Brazil are described, and their host species listed. A key to the four species is also included. |
