New species of freshwater crab genus Kingsleya Ortmann, 1897 (Decapoda: Brachyura: Pseudothelphusidae) from Piauí, northeastern Brazil

Abstract

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

An observational record of Kingsleya attenboroughi Pinheiro & Santana, 2016 (Decapoda, Pseudothelphusidae), an endemic species from the Chapada do Araripe, southern Ceará, Brazil

“…The Pseudothelphusidae is the most diverse of these families, with approximately 290 described species (Yeo et al 2008;Cumberlidge et al 2014;Acevedo-Alonso and Cumberlidge 2021). In Brazil, most pseudothelphusids occur in the Amazon basin (Magalhães 2016); however, species have been recently described in high-altitude swamps and humid forest zones of northeastern Brazil (Pinheiro and Santana 2016;Pralon et al 2020;Santos et al 2020a).…”
