Abstract
Abstract A new species of freshwater crab, Kingsleya parnaiba n. sp., collected in a tributary stream of the Parnaiba River Basin in Brazil, is described and illustrated. Kingsleya parnaiba n. sp. morphologically resembles Kingsleya attenboroughi Pinheiro and Santana, 2016 and Kingsleya gustavoi Magalhaes, 2005, from which it can be separated by a set of characters of the first gonopod, chelipeds, and female abdomen.

Despite most species of this tribe being commonly distributed in the Amazon River Basin (Magalhães, 2005), recent studies have shown a great diversity outside this basin, with the Ceará State as the eastern limit (Pinheiro and Santana, 2016) and Rondônia State as
The specimens were collected in the Riacho do Manezinho, close to the Parnaíba River, in the municipality of Ribeiro Gonçalves, 07°33’20”S 45°14’31”W (Fig. 1)
