Morphological and molecular characterization of a new species of fredius (decapoda, pseudothelphusidae) from rondônia, southern amazonia, Brazil

A new species of freshwater crab of the genus Fredius Pretzmann, 1967, from the state of Rondônia, Brazil, is described, illustrated, and characterized in terms of an mtDNA sequence (16S rRNA). Fredius buritizatilis sp. nov. is distinguished from its congeners by the following characters of the male...

A new species of freshwater crab of the genus Fredius Pretzmann, 1967, from the state of Rondônia, Brazil, is described, illustrated, and characterized in terms of an mtDNA sequence (16S rRNA). Fredius buritizatilis sp. nov. is distinguished from its congeners by the following characters of the male first gonopod: A mesial lobe comprising a long, narrow, spear-like projection that is recurved upward; a cephalic lobe with a distinctly inflated proximal portion with a large patch of strong, corneous spines along its mesial and caudal surfaces; and an auxiliary lobe on the caudal surface that is inflated and shorter than cephalic lobe. The mt16S rRNA sequence of Fredius buritizatilis sp. nov. establishes its systematic position in relation to other species of Fredius included in the analysis. The occurrence of several species of Pseudothelphusidae in the state of Rondônia, Brazil, as well as the relationships of Fredius buritizatilis sp. nov. to other species of the genus, suggests that the affinities of some Brazilian pseudothelphusids are not as close as their geographical proximity might suggest. © Koninklijke Brill NV, Leiden, 2014. 2020-06-15T21:48:48Z 2020-06-15T21:48:48Z 2014 Artigo https://repositorio.inpa.gov.br/handle/1/17687 en Volume 19, Pags. 101-114 Restrito Crustaceana Monographs
