Checklist of the species of Macrobrachium Spence Bate, 1868 (Decapoda: Caridea: Palaemonidae) from the lower Parnaiba River basin, Piaui, Brazil

Abstract

We present herein the results of a brief field survey of species of Macrobrachium Spence Bate, 1868 in three points of the northern portion of the lower Parnaiba River basin. The northern region of the lower Parnaiba River basin is part of the Environmental Protection Area Delta do Parnaiba and comprises several lakes, coastal lagoons, and the delta of the Parnaiba River. In total, we found five species: Macrobrachium acanthurus (Wiegmann, 1836), Macrobrachium amazonicum (Heller, 1862), Macrobrachium carcinus (Linnaeus, 1758), Macrobrachium jelskii (Miers, 1877), and Macrobrachium olfersii (Wiegmann, 1836) all of which are new records for the region.
