Abstract

Although the cladoceran Anthalona neotropica Sousa, Elmoor-Loureiro and Debastiani-Júnior, 2015 has a wide geographic range in Brazil, until now, it has only been reported in a few localities. The present study reports the occurrence of this species in the estuaries of the Jequitinhonha River and Una River, representing the first records of An. neotropica in Bahia State, Brazil.

Highlights

During the last two decades, knowledge on the taxonomy and phylogenetic position of Alona verrucosa Sars, 1901 (Crustacea: Cladocera: Chydoridae) has increased
Sousa et al (2015) have synthesized the knowledge on Anthalona species occurring in Brazil, with An. verrucosa presenting the majority of the records and the widest geographic range
These authors showed the occurrence of Anthalona brandorffi (Sinev and Hollwedel, 2002), Anthalona acuta Van Damme, Sinev and Dumont, 2011, and the new species Anthalona neotropica Sousa, Elmoor-Loureiro and Debastiani-Júnior, 2015 within the distribution range of An. verrucosa

Summary

Introduction

During the last two decades, knowledge on the taxonomy and phylogenetic position of Alona verrucosa Sars, 1901 (Crustacea: Cladocera: Chydoridae) has increased. Sousa et al (2015) have synthesized the knowledge on Anthalona species occurring in Brazil, with An. verrucosa presenting the majority of the records and the widest geographic range These authors showed the occurrence of Anthalona brandorffi (Sinev and Hollwedel, 2002), Anthalona acuta Van Damme, Sinev and Dumont, 2011, and the new species Anthalona neotropica Sousa, Elmoor-Loureiro and Debastiani-Júnior, 2015 within the distribution range of An. verrucosa. In contrast to other Anthalona species occurring in Brazil, which possess chitinized spines on setae of inner distal lobe (IDL) of the trunk limb I, An. neotropica presents just fine spinules on this limb This is a typical feature of the simplex-branch of Anthalona (Van Damme et al, 2011). The present paper aims to report the occurrence of An. neotropica in southern Bahia, as a result of an investigation on zooplankton of two estuarine regions
