The Anostraca is a diversified crustacean group inhabiting essentially in temporary wetlands on all continents. The genus Dendrocephalus sensu stricto is endemic to tropical or subtropical Neotropical fresh water pools. Of the 13 described species, four are reported from Brazil. Species identification is based on morphological differences on the complex frontal appendage, the anterior thoracopods, and the gonopods. After a detailed comparison of the different Brazilian populations, we developed an illustrated identification key based on the variations of the frontal appendage. This key include...
