Abstract

The freshwater prawn Macrobrachium amazonicum has a wide distribution throughout the Brazilian territory, occurring in several states and even in other countries, molecular studies report that some populations of this species are isolated due to geographical barriers, possessing a high degree of endemism. Later, a new species was described from one of these populations that previously were denominated like M. amazonicum, happening to be Macrobrachium pantanalense, even if with a low genetic distance. In view of this, in view of the presented scenario, the present study aims to address different aspects of the Biology of these two species by performing a comparative analysis searching dissimilarities in important characteristics that are usually used to distinguish species of the same genus. Individuals of both species will be collected in the type localities where they have been previously reported in other studies. In step 1 the geometric morphometry of the two species will be evaluated, using important morphological structures in the separation of species. In step 2, the spermiotaxonomy of both species will be performed, analyzing and comparing the patterns of the spermatozoid ultrastructure. In step 3 the description of the larval development of both species will be carried out, later the larval morphology will be compared based on the morphology of appendices and number of stages. In step 4 we will observe the behavior of interspecific recognition of copula of species and between species and also viability of the embryos. (AU)
