A new species of Kingsleya (Crustacea: Decapoda: Pseudothelphusidae) from the Xingu river and range extension for Kingsleya junki, freshwater crabs from the southern amazon basin

Abstract

Kingsleya castrensis sp. nov., a pseudothelphusid crab is described and illustrated from the Xingu River, state of Pará, southern Amazon region, Brazil. The new species is characterized by the male first gonopod bearing a large, well-developed apical plate, with a broadly rounded, thick distal lobe. New records of Kingsleya junki Magalhães, 2003 extend the distribution of this species eastward to the Tocantins River basin, in the state of Pará, Brazil.
