Chondrochelia Guţu, 2016 (Crustacea, Peracarida, Tanaidacea, Leptocheliidae) from North America: new species, redescription and distribution using morphological and molecular data

Until now, four species of the genus Guţu, 2016 have been recorded from America. Using morphological and molecular data, we were able to recognize and describe two new species, sp. nov. from the Mexican Caribbean and sp. nov. from the Gulf of Mexico. We found significant genetic divergence values be...

Description
Summary:Until now, four species of the genus Guţu, 2016 have been recorded from America. Using morphological and molecular data, we were able to recognize and describe two new species, sp. nov. from the Mexican Caribbean and sp. nov. from the Gulf of Mexico. We found significant genetic divergence values between species based on the nucleotide sequences of cytochrome oxidase subunit I to support the morphological data. Also, the range of distribution of two species: (Jarquín-González, García-Madrigal & Carrera-Parra, 2015) and (Jarquín-González, 2016), were expanded within their described geographic regions. In contrast, the supposed distribution of the Brazilian in the Mexican Caribbean and the Gulf of Mexico was rejected. Additionally, (Harger, 1878) was redescribed based upon type material. Minute details and ornamentation of some structures of three species were examined using SEM.
