Summary

Catops nathani Perkovsky 2001 from Late Eocene Baltic amber is redescribed using propagation phase contrast synchrotron radiation microtomography. Further description of the external morphology is given and genitalia are illustrated. This redescription allows C. nathani to be placed in the “alpinus” species group of the genus Catops.
