Redescription of Hargeria rapax (Harger, 1879) and description of H. chetumalensis a new species from the Mexican Caribbean (Crustacea, Peracarida, Tanaidacea, Leptocheliidae) based upon morphological and molecular evidence
Until now, Hargeria was considered a monospecific leptocheliid genus, with the species Hargeria rapax considered a taxon with a wide distribution, from the Northwestern Atlantic to the Mexican Caribbean. Herein, after a detailed revision of type and topotype materials and specimens collected from th...

Until now, Hargeria was considered a monospecific leptocheliid genus, with the species Hargeria rapax considered a taxon with a wide distribution, from the Northwestern Atlantic to the Mexican Caribbean. Herein, after a detailed revision of type and topotype materials and specimens collected from the Mexican Caribbean, a new species H. chetumalensis sp. nov. is described, and the redescription of H. rapax is provided. Also, we found a significant genetic divergence between the two species based on the nucleotide sequences of cytochrome oxidase subunit I, which support the morphological data. The morphological features used to recognize both species are also adequate to link males, females, and juvenile stages, although these species have a high intraspecific polymorphism. |
