A review of the freshwater crabs of the genus Hypolobocera Ortmann, 1897 (Crustacea: Decapoda: Brachyura: Pseudothelphusidae), from Colombia

A review of the species of Hypolobocera from Colombia is presented. A total of 18 species and four subspecies occur in this country. Diagnoses, illustrations, and a key for the identification of species and subspecies based on the morphology of the first male gonopod, are included. The geographical distribution of the genus, species and subspecies is updated based on new material. Two new species, Hypolobocera murindensis and H. velezi, are described and illustrated. Two more groups of Hypolobocera species, groups 7 and 8, are defined to accommodate H. alata Campos, and H. andagoensis (Pretzmann). One subspecies, H. bouvieri rotundilobata, is elevated to specific rank.
