After the paper by Guzmán et al. (2016) was published, an error related to the catalog numbers of the fossils specimens was pointed out. The codes UN-DG-CR-021 and UN-DG-CR-022 had already been used in the description of Colombian specimens of the lobster Meyeria magna M'Coy, 1849, in the publications of González-León (2016) and González-León et al. (2016), forcing us to replace these numbers. By mutual agreement between the authors, new catalog numbers were assigned by the Paleontological Collection of the Universidad Nacional de Colombia.
The correct catalog numbers are found below (corrections are in bold).
In 4. Material (p. 95). Two specimens are deposited in the Paleontological Collection of the Universidad Nacional de Colombia, Facultad de Ciencias, Departamento de Geociencias, Bogotá D.C., Colombia, under catalog numbers UN-DG-CR-031 and UN-DG-CR-032.
